A customer says something went wrong, and you can refund now or wait to see if they ask their bank. Chargeback vs refund looks close, but the sums say otherwise. Here is what each costs a UK seller.
In a chargeback vs refund choice, the chargeback costs more whenever the customer is right: you lose the sale, pay the £10 fee and take a mark on your chargeback rate, even if you later win. A refund costs only the sale. If the customer is wrong, fighting can beat refunding.
This guide is for you if:
- You run a UK Shopify store and keep asking yourself whether to refund an unhappy customer or "see what happens".
- You have lost money on disputes and want to see, with real numbers, when a refund would have cost less.
- You want a simple break-even rule, a decision table and a template you can use on the next borderline case.
Last updated: 9 October 2026. Written by the ChargeFix team.
The 30-second answer (TL;DR)
- In a chargeback vs refund comparison, a refund costs the sale price. A lost chargeback costs the sale price plus the £10 fee, and a won chargeback costs nothing in cash but still counts toward your chargeback rate.
- Shopify withdraws the amount and the £10 fee as soon as a chargeback is filed. Winning returns both. Losing or accepting returns neither the fee nor the sale.
- A simple break-even rule: fight rather than refund only when your chance of winning is higher than £10 divided by (sale price + £10). On a £60 sale that is about 14 percent.
- That rule ignores three things: the dispute still counts in your chargeback rate, fighting takes your time, and a customer who is right is unlikely to be a win.
- You cannot refund once a chargeback is open, so the decision has to be made before the customer goes to the bank.
- Refund fast when the customer is right and the value is low. Fight when the evidence is strong. Accept only when you know you cannot win.
What is the real difference in a chargeback vs refund choice?
In any chargeback vs refund choice, a refund is your decision and a chargeback is the bank's decision. That is the whole difference, and everything else follows from it.
With a refund, you send the money back, you control the timing, the amount and the message, and the matter ends. The cost is the amount you refund. With a chargeback, the customer asks their card issuer to reverse the payment, the issuer reviews evidence from both sides, and a third party decides. You lose control, and you pay for the privilege.
Shopify describes the process this way. When a customer files a chargeback, the disputed amount and the chargeback fee are withdrawn immediately. You then have a response window that is normally 7 to 21 days after the chargeback is filed. A card issuer review can take up to 75 days after you submit your response. If you win, you get the amount and the fee back. If you lose or accept, you get neither back, and there is no appeal. For UK merchants the fee is £10.
An inquiry is a gentler cousin. Shopify says that in an inquiry nothing is taken from you, and a full refund during an inquiry ends it, while a partial refund does not. So an inquiry is the last moment at which a refund is still a clean option.
| Point | Refund | Chargeback |
|---|---|---|
| Who decides | You | The card issuer |
| Money taken | When you choose | Immediately, with the fee |
| Fee | None from you for the refund itself | £10, returned only if you win |
| Time | Minutes | 7 to 21 days to respond, then up to 75 days for review |
| Appeal | Not needed | None |
| Effect on chargeback rate | None | Counts, even if you win |
| Control over the customer relationship | Yours | Mostly lost |
The last two rows are the ones sellers underrate. A refund never touches your chargeback rate. A chargeback does, win or lose.
How much does a chargeback cost you in cash?
In cash, a chargeback costs one of two things. If you lose, you lose the sale plus the £10 fee. If you win, you lose nothing, though you spend time. There is a third outcome, accepting the chargeback, which costs the same as losing.
Illustration: the cash outcomes on a £60 order.
| Outcome | Cash out | Cash back | Net cost |
|---|---|---|---|
| Refund the customer | £60 | £0 | £60 |
| Lose the chargeback | £60 + £10 fee = £70 | £0 | £70 |
| Accept the chargeback | £70 | £0 | £70 |
| Win the chargeback | £70 | £70 | £0 |
The chargeback vs refund comparison shows why a refund beats a lost chargeback by exactly the fee: £60 against £70. It also shows why a won chargeback beats a refund by the full sale price. Everything turns on how likely you are to win.
These are cash figures and leave out the cost of the product itself, which you have already lost if the customer keeps it or if the parcel never arrived. They also leave out what happens to your chargeback rate, covered below. Amounts are illustrative.
What is the break-even rule for chargeback vs refund?
You can settle a chargeback vs refund choice with one line of arithmetic. Let S be the sale price and p be your chance of winning, as a decimal.
- Cost of refunding: S.
- Expected cost of fighting: (1 minus p) x (S + £10), because you only lose the sale and fee if you do not win.
Fighting is cheaper than refunding when (1 minus p) x (S + £10) is less than S. Rearranged, that means p must be greater than £10 divided by (S + £10).
| Sale price | Break-even win chance | Meaning |
|---|---|---|
| £20 | 33% | Fight only if you have a good case |
| £40 | 20% | Fight if you think you have a fair chance |
| £60 | 14% | Fight unless the case is very weak |
| £100 | 9% | Fight almost always, if evidence exists |
| £250 | 4% | Fight, unless there is no evidence at all |
Check the sum for £60. £10 ÷ (£60 + £10) = £10 ÷ £70, which is 14.3 percent. If your chance of winning is 25 percent, the expected cost of fighting is 0.75 x £70 = £52.50, which is less than the £60 a refund costs. If your chance is 10 percent, fighting costs 0.9 x £70 = £63, which is more than £60.
The chargeback vs refund rule tells you something useful: on higher-value orders, fighting beats refunding even when your odds are poor, in cash terms. This is also where the rule misleads, because it leaves out three things. Our should I fight a chargeback calculator is built for the same question if you want a quick chargeback vs refund check on a live case.
Where does the chargeback vs refund rule break down?
First, your time. Building a response can take an hour or more, and your hour is worth something. If you value an hour at £20, add that to the cost of fighting. On a £20 sale, the break-even jumps well above 33 percent.
Second, the chargeback rate. A refund does not count. A chargeback does, even when you win. Chargeback rate is chargebacks in a month divided by chargeback-eligible transactions, and winning does not remove a dispute from it.
Third, the odds themselves, which decide every chargeback vs refund case. A customer who is right, such as one who really never got the parcel, gives you little chance of winning. The rule assumes you can estimate p honestly, and most sellers overestimate it when they are annoyed.
How does chargeback vs refund change your chargeback rate?
The chargeback rate is the share of your transactions that end in a chargeback. Shopify measures it as the chargebacks in a month divided by the chargeback-eligible transactions in that month. Winning a dispute does not take it out of the count. A refund, on the other hand, never enters the count at all.
That is the strongest argument in the chargeback vs refund debate for refunding early. A payments-industry guide I read makes the same point: a chargeback counts against your ratio even if you win, and a refund avoids this. Shopify publishes no store-closure threshold, so I cannot tell you the number at which a store is shut down. The guides I read suggest keeping the ratio well below 1 percent. Visa's VAMP programme is reported to use 1.5 percent from April 2026, and you should confirm the current figures with your processor.
Illustration: the rate effect. In one month you have 500 eligible transactions. Five customers have problems.
| What you do | Chargebacks | Chargeback rate |
|---|---|---|
| Refund all five | 0 | 0.0% |
| Refund two, fight three | 3 | 0.6% |
| Fight all five | 5 | 1.0% |
Even if you win all five fights, the rate in the last row is 1.0 percent. If you refunded them all, the rate is zero. For a small shop with a few hundred orders a month, a handful of chargebacks can move the rate noticeably. That is why a refund can be worth more than its cash cost. Amounts are illustrative, and the effect on your account depends on your processor's rules.
Our guide to what happens when you lose a chargeback covers how disputes affect your account, and our Shopify chargebacks UK guide has the wider picture.
When does a refund win the chargeback vs refund choice?
A refund is the better choice when the customer is probably right, when the order is low in value, when your evidence is thin, or when you are worried about your chargeback rate. In plain terms: if you would not want to explain your position to a reasonable stranger, make a goodwill refund.
Specific cases where a refund usually wins:
- The parcel never arrived and you have no strong proof. The customer is likely right, and a refund costs less than a lost dispute.
- A low order value with a bad record. At a low order value, the hour of effort costs more than the sale.
- A repeat or valued customer. The relationship is worth more than the margin.
- A problem you caused. A wrong item, a late delivery or a faulty product are all cases where fighting is hard to justify.
- A dispute that is only an inquiry. A full refund ends it with no fee.
- A shop already near its comfortable rate. One more chargeback is not worth the risk.
The cleanest refund is the one made before the customer contacts the bank. Shopify says you cannot issue a refund after a chargeback has been made. If the customer asks their bank for an inquiry, you can still refund, and a full refund ends it.
When does a chargeback fight win the chargeback vs refund choice?
In a chargeback vs refund decision, fight when you have strong evidence, when the sale value is high enough to justify the effort, and when the customer's claim looks wrong. In a chargeback vs refund decision the facts tip the balance. Examples:
- The parcel was delivered with a signature or photo. Shopify lists shipping and tracking information, and says a signature significantly strengthens your position.
- The customer received the product and used it. You hold messages and delivery proof.
- A fraud claim where the delivery matches the cardholder's details. The evidence links the buyer to the order.
- The customer was refunded before the dispute. Refund records matching the disputed charge are the strongest evidence in a credit not processed case.
- A high order value. Even a modest chance of winning can beat the cost of a refund.
Remember that Shopify Payments adds some evidence automatically, including order details, addresses, IP address, fulfilment details, a tracking PDF and previous orders. You add the rest: messages, policies and the proof of what the customer was told. The better your records, the higher p becomes. Our guide to the evidence to save at fulfilment shows how to build them.
When should you accept the chargeback?
Accepting costs the same as losing: the sale and the fee. So accept only when you know you cannot win and want to stop spending time. Shopify's own list of reasons notes that for a genuine duplicate charge, or a charge after a cancellation, you must accept. For other cases accepting is a choice, and usually a poor one if you have any real evidence.
Accepting does have one benefit: it ends the matter quickly, and you can use the time to fix the cause. But if you are going to accept, you should have refunded earlier. A refund would have cost £10 less and left your chargeback rate untouched.
How does chargeback vs refund change by dispute reason?
The right move depends on why the customer is unhappy. Shopify groups disputes into reasons, and each one changes the odds. Use this table as a starting point for a chargeback vs refund choice, then check the evidence you actually hold.
| Dispute reason | Typical position | Chargeback vs refund leaning |
|---|---|---|
| Product not received | Good if you hold delivery proof; weak if not | Fight with signature or photo; refund if proof is thin |
| Credit not processed | Strong if you refunded earlier | Fight with refund records; refund first if you have not yet |
| Product unacceptable | Depends on the listing and the customer's attempt to return | Offer a fix or refund early; fight if the listing was accurate |
| Fraudulent | Depends on whether the buyer can be linked to the order | Fight when delivery and billing details match |
| Unrecognised | Often a descriptor problem | Contact the customer; ask them to withdraw; fight with order records |
| Duplicate | Shopify says to accept a genuine duplicate | Refund the extra charge at once |
| Subscription cancelled | Shopify says to accept a charge after cancellation | Refund and fix your cancellation process |
| General | Varies | Judge on the evidence |
The pattern is that the more objective your evidence is, the better fighting looks. Delivery scans, signatures and refund records are objective. A story about what the customer "must have known" is not. Where your evidence is mostly a story, refund. Where it is mostly records, fight.
For the duplicate and subscription rows, notice that Shopify's own guidance is to accept. In those cases the chargeback vs refund choice has already been made for you, and the only question is whether you refunded before the bank got involved.
How does order value change the chargeback vs refund maths?
Order value changes the break-even, but also the effort. Here is how the maths looks at different prices, using the £10 fee and an hour of your time at £20. Assume a 30 percent chance of winning in each row.
| Sale price | Cost of refund | Expected cost of fighting (no time) | Expected cost of fighting (with £20 time) | Better move |
|---|---|---|---|---|
| £20 | £20 | 0.7 x £30 = £21 | £41 | Refund |
| £40 | £40 | 0.7 x £50 = £35 | £55 | Refund (with time included) |
| £80 | £80 | 0.7 x £90 = £63 | £83 | About equal; judge the evidence |
| £150 | £150 | 0.7 x £160 = £112 | £132 | Fight |
| £300 | £300 | 0.7 x £310 = £217 | £237 | Fight |
The sums are simple, and order value drives them: expected cost of fighting is (1 minus the chance of winning) x (sale + fee), and the time column adds £20. The table shows how time matters most at a low order value and almost disappears at high ones. Amounts are illustrative, and your own win rate may be much higher or lower than 30 percent, so use your own figures where you have them. Charle's Shopify chargebacks guide cites a manual win rate of about 12 percent, but that is a third-party figure I could not verify, so do not treat it as a benchmark for your store.
What does a double refund look like, and how do you avoid it?
A double refund is when you refund a customer and they also have a dispute open, so the customer is paid twice and you pay twice. The payments-industry guide I read warns that a double refund happens when a merchant refunds a transaction that a customer has also disputed can lose twice the transaction cost plus fees. Shopify staff on the Community forum have also advised against refunding during a chargeback for this reason.
Illustration: the double refund loss. A customer disputes a £60 order. You do not notice and refund £60 the same day. The chargeback goes through and you lose it. You are out the £60 refund, plus £60 withdrawn by the bank, plus the £10 fee: £130 for a £60 sale. Amounts are illustrative.
Shopify says you cannot issue a refund after a chargeback has been made, so in many cases the system will stop you. But the risk is real when a dispute is filed just before or just after you refund. The safe habit is simple: before you refund any order, check whether it has a dispute. Our guide on refunding a customer who has opened a dispute explains the order of steps, and our guide on what to do when a customer is refunded but still disputes covers the aftermath.
What are the hidden costs of chargeback vs refund?
The cash chargeback vs refund comparison leaves out costs that are real but harder to count. Here they are side by side.
| Hidden cost | Refund | Chargeback |
|---|---|---|
| Your time | Minutes | An hour or more to respond |
| Chargeback rate | None | Counts, win or lose |
| The product | Lost, unless returned | Lost if you lose, kept if you win |
| Postage | Already spent | Already spent |
| Customer relationship | Often preserved | Usually lost |
| Processing fee on the sale | Depends on your plan | Depends on your plan |
| Risk to the account | None | Rises with the rate |
Whether Shopify returns its processing fee when you refund or lose a chargeback depends on your plan and terms, and I have not verified the current treatment, so check your own fee schedule before you include it in your sums.
The payments-industry guide I read says that once fees, customer service and acquisition costs are included, a chargeback can cost more than twice the original transaction amount in total. That is the guide's claim, not a figure I could verify independently, so treat it as an upper-end illustration, not a rule. The direction is plain enough without it.
How do you decide chargeback vs refund in practice?
Use this chargeback vs refund table when a customer complains and you are tempted to wait.
| Situation | Customer likely right? | Evidence | Best move |
|---|---|---|---|
| Customer asks for a refund, no dispute yet | Yes | Any | Refund promptly, save the record |
| Customer threatens a chargeback | Maybe | Medium | Reply fast, offer a refund or fix, save the thread |
| Inquiry opened, nothing taken | Maybe | Medium | Full refund ends it; consider if the claim is fair |
| Chargeback filed, strong evidence | No | Strong | Fight with a full response |
| Chargeback filed, weak evidence | Yes | Weak | Accept, or fight only if the sale is high |
| Chargeback filed, customer was already refunded | No | Strong | Fight, using the refund records |
| Genuine duplicate or post-cancellation charge | Yes | n/a | Accept, as Shopify says you must |

How should you word a goodwill refund?
A goodwill refund is a good moment to protect yourself. A clear, kind message helps the customer feel looked after and keeps a record of what you did and why. Keep it short and specific.
Subject: Your refund for order [number]
Hi [name],
I am sorry this did not go as it should have. I have refunded
£[amount] to your original payment method. Depending on your
bank, you should see it in a few working days.
If you have any questions, reply to this email and I will help.
[Name]
Save the refund confirmation with its date, amount and transaction reference. If a dispute is filed afterwards, Shopify's guidance for credit not processed is to submit evidence that you refunded the customer before the chargeback, so this record could be the whole of your response. A refund you cannot prove is a refund that might as well not have happened.
Is a goodwill refund an admission of fault?
Not necessarily. A goodwill refund does not mean you say the customer was right. The wording above does not say the order was your fault. If you want to be careful, say "as a gesture of goodwill" and leave it there. A refund is a commercial decision. But keep in mind that a refund does not stop a customer who has already filed a dispute, and you must check for one first.
What's different for UK merchants?
This section is general information, not legal advice. For UK stores, the main differences are the £10 chargeback fee, the 120 day claim window MoneyHelper describes, Section 75 for credit card purchases from £100 to £30,000, and consumer rights under UK law.
Many chargeback vs refund guides quote dollar fees from $5 to $50 and US consumer law, so their sums do not transfer to a UK shop. Your fee is £10 on Shopify Payments, which makes the chargeback vs refund break-even rule above much easier to apply, and your customers have rights under the Consumer Rights Act 2015 and the Consumer Contracts Regulations 2013 that sometimes require a refund regardless of what a chargeback would cost.
In particular, under the Consumer Contracts Regulations, regulation 34, a refund after a distance sale cancellation is due without undue delay and within 14 days. So in some cases chargeback vs refund is not really a choice. If the customer is entitled to a refund, you owe it, and the question is only whether to pay it now or after a dispute that you are likely to lose. Take your own advice on specific cases.
Credit card buyers also have Section 75, with a customer able to claim from their card provider for purchases from £100 to £30,000. That is another route to the same money, which means a refusal does not end the matter.
MoneyHelper says buyers typically have 120 days to make a chargeback claim, so a decision not to refund today can come back months later. For how long you may keep records, I have not verified ICO guidance, so take your own data protection advice.
How do you review chargeback vs refund numbers each month?
Once a month, spend fifteen minutes on your chargeback vs refund numbers. How many refunds did you issue? How many chargebacks did you receive? What did each cost? You will probably find that a few causes account for most of both, such as late delivery, unclear descriptions or a supplier problem.
MONTHLY REFUND VS CHARGEBACK REVIEW
Eligible transactions: ___
Refunds issued: ___ Value: £___
Chargebacks received: ___ Value: £___ Fees: £___
Won: ___ Lost: ___ Accepted: ___
Chargeback rate: ___% (chargebacks ÷ eligible transactions)
Top cause: ___
One fix for next month: ___
If chargebacks are costing more than refunds, move your decision point earlier. Reply faster, offer refunds sooner and fix the cause. If refunds are rising sharply, look for a product or delivery issue. The chargeback vs refund numbers tell you where the problem lies.
What are the most common chargeback vs refund mistakes?
- Waiting to "see if they actually dispute". If they do, you lose the option to refund.
- Ignoring the chargeback rate in a chargeback vs refund choice. A won dispute still counts.
- Overestimating your chance of winning. Be honest about the evidence when you weigh chargeback vs refund.
- Forgetting your own time. An hour of work belongs in the sum.
- Refunding without checking for a dispute. That is how double refunds happen.
- Refunding without saving the confirmation. You may need it as evidence.
- Accepting without checking. Accepting costs the same as losing.
- Fighting every case on principle. Principle is expensive at £10 a time.
Frequently asked questions
Is chargeback vs refund cheaper for a UK seller?
A refund is cheaper whenever the customer is likely right. It costs the sale price. A lost chargeback costs the sale price plus the £10 fee, and a won one costs nothing in cash but still counts in your chargeback rate. Fighting beats refunding only when your chance of winning is above £10 divided by (sale price + £10).
How much is the chargeback fee for UK merchants?
Shopify charges £10 for UK merchants. The chargeback fee is withdrawn together with the disputed amount as soon as the chargeback is filed. If you win, both come back. If you lose or accept, the fee does not come back, and there is no appeal, so the chargeback fee is a real cost on every lost case.
Does a refund affect my chargeback rate?
No. The chargeback rate is chargebacks in a month divided by chargeback-eligible transactions, and a refund is not a chargeback. A chargeback counts toward the rate even if you win it. That is one reason an early refund can be worth more than its cash cost.
Can I refund after the customer files a chargeback?
No. Shopify says you cannot issue a refund after a chargeback has been made. If the customer opened an inquiry instead, you can refund, and a full refund ends it while a partial one does not. Decide before the customer goes to the bank, and check for an open dispute before any refund.
What is the break-even win chance in chargeback vs refund?
It is £10 divided by (sale price + £10). On a £60 sale that is about 14 percent. If you think you have a better chance than that, fighting costs less than refunding in cash terms. The rule ignores your time and the effect on your chargeback rate, so use it as a guide, not a rule.
What happens if I refund and the customer still disputes?
You can end up paying twice: once by refund and once when the bank withdraws the amount. Shopify staff on the Community forum have advised against refunding during a chargeback for this reason. If it happens, respond to the dispute with proof of the refund, which is strong evidence in a credit not processed case.
Should I accept a chargeback to save time?
Accepting costs the same as losing, so it only makes sense when you cannot win and want to stop spending time. Shopify says you must accept a genuine duplicate charge or a charge after cancellation. Otherwise, if you hold real evidence, a response is usually worth the effort.
Is chargeback vs refund different for a high-value order?
In a chargeback vs refund choice on a high-value order, fighting looks better in cash terms, because the break-even win chance is low. At £250 it is about 4 percent. But it is only worth fighting if you have evidence and are willing to accept the effect on your chargeback rate. A refund early is still the cleanest chargeback vs refund answer when the customer is right.
How long can a customer wait before filing a chargeback?
MoneyHelper says buyers typically have 120 days to make a chargeback claim. So a refusal today can become a dispute months later, and you should keep your records for at least four months after the sale. Credit card buyers can also claim under Section 75 for purchases from £100 to £30,000.
