True cost of a chargeback in the UK (calculator)

Count the goods and the sale price together and you count the same stock twice. Count them once and the true price of a dispute is easier to see, and easier to cut.

The true cost of a chargeback in the UK is the disputed amount plus the fee, because the sale's own costs were spent either way. On Shopify Payments the fee is £10 and it comes back if you win. On a £60 order, a lost chargeback costs you £70 against the profit you expected, before your time.

Last updated: 3 October 2026. Written by the ChargeFix team.

The 30-second answer (TL;DR)

Measured against the profit you expected, a lost chargeback costs the disputed amount plus the fee. Measured as cash out of pocket, it costs your goods, shipping, payment fees and the fee. These are two views of the same loss, so never add them together.

The Shopify fee in the UK is £10 and is returned if you win. Stripe's UK fee is £20, which is never returned, plus a £20 counter fee that comes back only on a win.

Your time is the one cost you can see coming. Two and a half hours on a £60 order is worth more than the £10 fee at almost any hourly rate.

The £10 weighs most on small baskets. At a 1% chargeback rate, the cost per £100 of sales is £1.40 on a £25 average order and £1.08 on a £120 one.

Winning removes the amount and the fee from your loss. It does not remove the dispute from your chargeback rate.

We could not confirm from Shopify's pages whether the original payment processing fee is returned, so the calculator treats it as an input you check against your own payouts.

Whether to fight is a separate sum. The calculator below turns your own numbers into a decision.

What is the true cost of a chargeback in the UK?

The true cost of a chargeback in the UK is what the dispute takes from you compared with a normal sale. On a lost dispute that is the disputed amount plus the fee, with your time added on top. It is not the order value plus the goods, because the goods were already part of the sale.

Here is why. Follow £60 of money through an ordinary sale and then through a lost dispute.

Example 1 (illustration)

A customer pays £60.00 for an item that cost you £22.00. You pay £3.20 to post it. The payment fee is £1.45, which is 2% plus 25p on the Basic plan in Shopify's UK pricing as we opened it on 2 October 2026.

Step	Cash in	Cash out	Running position
The customer pays	£60.00		£60.00
You buy the item		£22.00	£38.00
You post it		£3.20	£34.80
Payment fee		£1.45	£33.35
Chargeback lost: amount reversed		£60.00	−£26.65
Chargeback fee		£10.00	−£36.65

Before the dispute you were £33.35 up. After it you are £36.65 down. The gap between the two is £70.00, which is the £60.00 disputed amount plus the £10.00 fee.

That £70.00 is the true cost measured against what you expected to earn. The £36.65 is the cash you are out of pocket. Both are correct, and they answer different questions. The first tells you what the dispute cost you. The second tells you how much cash has to come from somewhere else.

The mistake to avoid is adding the goods again. If you add £22.00 of goods to the £70.00, you reach £92.00, which is a number that never left your account.

How do you calculate the cost of a chargeback?

Use two lines. Measured against the profit you expected, the cost is the disputed amount plus the fee. Measured as cash, it is your cost of goods plus shipping plus the payment fee plus the chargeback fee. Then add your time. If you win on Shopify, the amount and the fee come back.

Keep the formulas in a spreadsheet so you can use them on every dispute.

Chargeback cost calculator (copy into Google Sheets or Excel)

Inputs
B2  Disputed amount (£)
B3  Chargeback fee (£)                     Shopify Payments UK: 10
B4  Cost of goods (£)
B5  Shipping you paid (£)
B6  Payment fee on the original sale (£)
B7  Hours you will spend
B8  Your hourly value (£)

Results if you lose or accept
B10 Swing against expected profit (£)      =B2+B3
B11 Cash out of pocket (£)                 =B4+B5+B6+B3
B12 Time cost (£)                          =B7*B8
B13 Total cost against expected profit     =B10+B12

Results if you win on Shopify Payments
B15 Swing against expected profit (£)      =0
B16 Cash out of pocket (£)                 =B4+B5+B6
B17 Time cost (£)                          =B7*B8
B18 Total cost against expected profit     =B15+B17

Notice what the sheet leaves out. If you win, the amount and fee come back, so B15 is zero and you are left with only the time you spent. That is why fighting on Shopify costs you time, not cash, when you already hold the evidence.

The payment fee in B6 needs one honest caveat. Shopify's chargeback help page we opened does not say whether the original processing fee is returned. Treat it as lost, and check your payout line items to see what actually happens for your store. If the fee is returned, set B6 to zero.

For the Shopify side of the maths, our post on the Shopify chargeback fee UK covers when the fee is charged and returned.

What does a chargeback cost on a £60 order?

On a £60 order, a lost Shopify chargeback costs £70.00 against expected profit and leaves you £36.65 out of pocket in Example 1. A win leaves you with your normal profit minus the time you spent. The time cost, not the fee, usually decides whether fighting is worth it.

Put the same order through the calculator in four outcomes. Time is 2.5 hours at £20 an hour, which is £50.00 and is an illustration, not a benchmark.

Outcome	Against expected profit	Cash out of pocket	Time cost	Total against expected profit
Accept, 0.25 hours at £20	£70.00	£36.65	£5.00	£75.00
Fight and lose	£70.00	£36.65	£50.00	£120.00
Fight and win	£0.00	−£33.35	£50.00	£50.00
Fight and win with a saved evidence folder, 0.5 hours at £20	£0.00	−£33.35	£10.00	£10.00

The row signs can confuse, so here is the key. A negative out of pocket figure means you are still in profit. In the winning rows, the £33.35 is the profit from the original sale, and the table shows it as a negative cost.

Read the table as a decision. Fighting and losing costs £45.00 more than accepting, and that £45.00 is all time: £50.00 minus £5.00. Fighting and winning saves £25.00 compared with accepting. The cash outcome swings by £70.00, and the time bill is the price of the chance.

Our post on whether you can win a Shopify chargeback covers how to judge that chance, and the break-even maths that follows from it.

How do you put a price on your time?

Estimate hours for each task, multiply by what an hour of your time is worth, and keep the figure honest. A dispute response often takes two to three hours when you gather messages, tracking, policy screenshots and files. Use your own hourly value, and record real hours after each dispute so the estimate improves.

The hours in the table are an illustration, not a benchmark. Your own log is the only number that counts.

Task	Illustrative hours
Find the dispute and read the claim	0.25
Collect tracking, order and delivery proof	0.75
Collect customer messages and policy screenshots	0.50
Build and size-check the files	0.50
Write the cover note and read it cold	0.50
Total	2.50

At £20 an hour that is £50.00. At £12 an hour it is £30.00. At £40 an hour it is £100.00. A founder who values an hour at £40 will not fight a £30 order for a £10 gain, and should not.

The time cost falls once you have a routine. A saved folder of policy screenshots, a template cover note and a habit of saving carrier proof at shipping can cut the hours on later disputes. Our guide to Shopify chargeback evidence and what Shopify submits for you shows what to prepare.

What else belongs in the cost of a chargeback?

Add anything that is a real cash effect: a return shipping label you paid for, a replacement you sent, and any extra fee on a failed debit. Leave out things you cannot price, such as goodwill. VAT on a lost sale is not covered in the sources we reviewed, so ask your accountant before treating it as recoverable.

Four extras come up often.

Return and replacement costs. If you shipped a replacement before the dispute arrived, that stock and postage are cash you have spent. Put them in B4 and B5.

Reserves. Shopify's monitoring page says a high chargeback rate can affect your Shopify Payments account health and can lead to actions such as reserves on payouts. A reserve does not cost you money directly, but it holds cash back from you. We found no figure for how large or how long a reserve is, so we have not priced it.

A bank debit. If your Shopify balance cannot cover a chargeback, Shopify debits your bank account outside the normal payout schedule, and a failed debit is retried after three business days. That can create a bank charge or an overdraft cost for you, which is yours to price.

Tax. We did not find guidance on VAT or tax treatment of a lost sale or a chargeback fee. Treat it as an open question for your accountant.

How much does a chargeback cost per £100 of sales?

At a 1% chargeback rate where every dispute is lost, the cost per £100 of sales is the average order value plus £10, divided by the average order value. That is £1.40 at a £25 average order and £1.08 at £120. The fixed £10 fee weighs most on small baskets.

The sum is simple. One dispute in every 100 orders, each costing the order amount plus the £10 Shopify Payments fee, spread over the sales that produced them.

Example 2 (illustration)

Every dispute here is lost, and time is left out so the fee effect is clear.

Average order	Cost of one lost dispute	Cost per 1,000 orders at 1%	Cost per £100 of sales
£25	£35	£350	£1.40
£40	£50	£500	£1.25
£55	£65	£650	£1.18
£80	£90	£900	£1.13
£120	£130	£1,300	£1.08

Two things follow. First, the cost can never fall below 1% of sales at a 1% rate, because the order amount alone is already 1%. Second, a lower average order pushes the figure up, because the fee is the same on a £25 sale as on a £120 one.

If you win some disputes, the amount and fee come back on those, so the real figure sits below the table. Cut the table by your own win share once you have a log.

What does a 1% chargeback rate cost a year?

A store with 1,000 orders a month at a £55 average order and a 1% chargeback rate sees 10 disputes a month. If it loses all 10, the cost is £650 a month, or £7,800 a year, before time. If it wins 3 of the 10, the cost falls to £455 a month.

Here are three outcomes for the same store, using the £65 cost of one lost dispute (£55 plus £10).

Disputes lost out of 10	Cost a month	Cost a year
10	£650	£7,800
7	£455	£5,460
5	£325	£3,900

This is an illustration, not a forecast. We found no audited UK win rate, so the 7 and 5 rows are there to show the shape of the sum, not to suggest what you will win.

Notice what moves the annual figure most. Winning five more disputes a year saves less than preventing five, because a prevented dispute also takes away the time and the rate pressure. That is the reasoning behind our chargeback rate calculator and thresholds post, which turns your own order counts into a rate.

Does the cost change if you sell on Stripe?

Yes. Stripe's UK dispute fee is £20 and is not returned, plus a £20 counter fee that comes back only if you win. On a £60 order, accepting costs £80, fighting and losing costs £100, and winning costs £20. The counter fee gives fighting a cash price that Shopify's does not.

Stripe's own pricing and support pages list those two fees for UK accounts, and say the counter fee is waived under Smart Disputes, which charges 30% of the amount on won disputes only. We have not confirmed who qualifies for it.

£60 order on Stripe, before time	Cost
Accept	£80 (£60 plus £20 received fee)
Fight and lose	£100 (£60 plus £20 plus £20)
Fight and win	£20 (received fee only)

Fighting beats accepting in cash terms only when your chance of winning is above 20 divided by the amount plus 20. At £60 that is 25%, at £100 it is 16.7%, and at £200 it is 9.1%. Add your time and the bar rises. Our guide to Stripe dispute fees in the UK covers the fee rules in full, and whether it is worth fighting a chargeback builds the decision table.

When does fighting pay once your time is counted?

With time counted at 2.5 hours against 0.25 hours for accepting, fighting a £60 Shopify order pays only if you win about 64% of the time. At £120 the bar drops to 35%, and at £250 to 17%. On a £25 order, fighting never pays, because a win costs more than accepting.

Extra time is the whole price of fighting on Shopify, because a loss costs the same cash as accepting. So the break-even win chance is the extra time cost divided by the extra time cost plus what a win saves.

Example 3 (illustration)

Time is £20 an hour. Accepting takes 0.25 hours (£5.00). Fighting takes 2.5 hours (£50.00). Fees and amounts are Shopify Payments UK.

Order	Accept	Fight and lose	Fight and win	Win chance needed
£25	£40.00	£85.00	£50.00	Never
£60	£75.00	£120.00	£50.00	64.3%
£120	£135.00	£180.00	£50.00	34.6%
£250	£265.00	£310.00	£50.00	17.3%

Each figure is the amount plus the £10 fee plus time on a loss, and time alone on a win. The £25 row shows the trap: a win costs £50.00, which is more than the £40.00 it costs to accept.

The result changes sharply when the hours do. With a saved folder and a template, the same dispute might take 0.5 hours (£10.00), so the extra time falls from £45.00 to £5.00. At £60 the break-even win chance then drops from 64.3% to about 7%. A routine does more for your cost than any single decision.

We found no audited win rate to compare these thresholds against, so judge your evidence honestly. Our post on whether it is worth fighting a chargeback turns this into a decision table by order value and evidence strength.

How much cash should you set aside for chargebacks?

Multiply your expected disputes a month by the cost of one lost dispute, then add a buffer for the first week. A store with 1,000 orders and a 1% rate expects 10 disputes, so at £65 each it sets aside £650 a month, plus enough in its bank account to cover an off-schedule debit.

Treat the figure as a monthly line in your cash plan, next to postage and payment fees, rather than as a surprise. Three practical points.

Use a cautious win share. Until your log shows otherwise, plan as though you lose every dispute, and treat any win as a gain. That is the safe way to budget without an audited win rate.

Plan for timing. A chargeback takes the amount and the fee when it is filed, and a win returns them later. Shopify says a decision can take up to 75 days after you submit evidence, so cash can sit out of your hands for weeks. Our post on how long a Shopify chargeback takes lays out the stages.

Keep the buffer where Shopify can reach it. If your Shopify balance cannot cover a chargeback, Shopify debits your bank account, so a balance that sits close to zero invites a failed debit.

How do you bring the cost of a chargeback down?

You cannot change the £10 fee, but you can change how many disputes you receive, how many hours each one takes, and how many are decided in your favour. Refund genuine problems early, save proof at the point of dispatch, and keep a template folder so each response takes less time.

Look at the cost formula and you will see only four levers.

Fewer disputes. Every dispute you prevent saves the amount, the fee and the time, and it lowers your chargeback rate. Clear product pages, honest delivery times and a fast reply to a worried customer are the unglamorous ways to do it.

An early refund. Stripe's documentation says responding to an inquiry or issuing a full refund avoids the dispute fee. If the customer is right, refunding before the dispute opens costs you the sale and nothing more. Once a chargeback has opened, Shopify says you cannot refund through it.

Fewer hours. The hours table earlier shows where the time goes. Saving carrier proof when you ship, keeping policy screenshots in one folder and reusing a cover note can take a lot of it away. Our post on what Shopify submits for you shows which parts you do not have to build yourself.

A better chance to win. Evidence matched to the reason raises your odds without guaranteeing anything. The bank decides, so keep expectations modest and let your own log tell you what works.

What should you do in the first 24 hours to limit the cost?

Note the due date, read the reason and amount, and run the calculator the same day. Decide whether to fight or accept before you collect anything, and, if you fight, save carrier proof first. A decision made on day one keeps the time cost to what the order is worth.

Work through this list in order.

Write down the evidence due date. Shopify gives a window of 7 to 21 days, so check the exact date in your admin.
Check whether it is an inquiry or a chargeback. An inquiry takes no money, and a full refund can end it before it becomes a chargeback.
Read the reason the bank recorded, because it decides which evidence matters.
Fill in the calculator with the real amount, goods, shipping and fee.
Estimate hours honestly from the task table above.
Decide fight or accept, and write the decision and the reason in your log.
If you fight, save carrier proof, customer messages and policy screenshots today, before links expire or inboxes fill.

For timing, our guide to how long a Shopify chargeback takes shows when money moves and when the answer lands.

How do you track the cost of chargebacks each month?

Keep one row per dispute and one total per month. Record the dates, amount, fee, hours spent and outcome, then sum the cost of each. After three months you will have your own average cost per dispute, which is a better number than any estimate in this post.

Copy this layout into a sheet.

Chargeback cost log (one row per dispute)

Order date | Dispute date | Order no. | Reason | Amount (£) | Fee (£)
Goods (£) | Shipping (£) | Hours | Hourly value (£) | Outcome | Payment fee returned? (Y/N/unknown)

Monthly totals
Disputes opened                    =COUNT of rows
Lost or accepted                   =COUNTIF(Outcome, "lost") + COUNTIF(Outcome, "accepted")
Cost against expected profit (£)   =SUM of (Amount + Fee) on lost or accepted rows
Time cost (£)                      =SUM of (Hours * Hourly value)
Chargeback rate (%)                =Disputes opened / orders in the month * 100

The last column answers the open question from earlier. Check your payout line items on the first few disputes you win, and note whether the original payment fee came back. After a handful of rows you will know your store's answer, which Shopify's pages do not give.

Keep the order date as well as the dispute date. A dispute can land months after a sale, so the month it hits your log is not the month the money came in.

What's different for UK merchants?

Three things matter in the UK: the £10 Shopify Payments fee in sterling, the way a shortfall is collected from your bank, and the length of time a customer has to dispute. This section is general information, not legal advice.

The fee. Shopify's help page lists £10 GBP for the United Kingdom and says it is returned if you win. Stripe's UK fees are £20 received and £20 countered. The Shopify pricing page does not list a chargeback fee, so use the help page, and see our Shopify Payments UK fees 2026 post for the processing rates.

Cash. If your balance cannot cover the chargeback, Shopify debits your UK bank account outside the normal payout schedule, and retries after three business days if the first attempt fails. Keep a buffer so a dispute does not trigger a bank charge.

The customer's side. MoneyHelper says a debit card gives chargeback protection on all purchases, with 120 days from the purchase date to claim. For credit cards it points to Section 75 for items costing £100 to £30,000, and chargeback within 120 days for other amounts. Disputes can therefore arrive months after the sale, so budget for them in your cash plan.

Rates. Pricing and fees change. Everything here was read on 2 October 2026, so check the current pages before relying on a figure. For the wider picture, start with our guide to Shopify chargebacks in the UK.

Common mistakes

Adding the goods on top of the order value. The goods are already inside the sale, so you count the same stock twice and overstate the loss.
Treating the £10 fee as the whole cost. On a lost dispute the amount is the larger part, and your time often outweighs the fee.
Leaving time out. Two hours spent on a £30 order can cost more than the order is worth.
Pricing every dispute at your average order value. The cost of a dispute is that order's amount, so use the real figure.
Assuming a win removes the dispute from your chargeback rate. The rate counts disputes opened, so a win saves money but not the count.
Assuming the original payment fee comes back. We could not confirm it, so check your payout line items and log the answer.
Using Shopify's fighting maths on Stripe. The Stripe counter fee is lost on a loss, so the break-even win chance is above zero.
Keeping no log. Without your own cost per dispute you will argue from estimates every time.

FAQ

How much does a chargeback cost a business?

On a lost dispute, a business loses the disputed amount plus the fee, which is £10 on Shopify Payments in the UK and £20 on Stripe. Add the hours spent responding. On a £60 order the total against expected profit is £70 before time on Shopify. A win returns the amount and, on Shopify, the fee.

Does the cost of a chargeback include shipping?

Only as part of your cash position. Measured against expected profit, shipping is already inside the sale, so it is not added to the disputed amount and fee. Measured as cash out of pocket, it joins your goods, the payment fee and the chargeback fee. Count it once in the view you choose, never in both.

How do you calculate chargeback loss?

Use the disputed amount plus the chargeback fee, then add the value of the hours you spend. For cash out of pocket, add your cost of goods, shipping, original payment fee and the chargeback fee instead. The two figures describe the same loss, so pick the one that answers your question and do not sum them.

What does a 1% chargeback rate cost?

At 1%, one order in 100 is disputed. If you lose every dispute, the cost per £100 of sales is the average order plus £10, divided by the average order. That is about £1.18 at £55 and £1.40 at £25, before time. Wins reduce the figure, and the rate itself still counts every dispute.

What is the chargeback cost per order?

Divide your monthly dispute cost by the number of orders in the month. A store losing 10 disputes at £65 each across 1,000 orders pays 65p per order, before time. Your own figure will differ with your average order value, your fee and your win share, so work it from your log.

Is the Shopify chargeback fee refundable?

Yes, if you win. Shopify's help page says the £10 UK fee is returned when the chargeback is won, and the disputed amount comes back too. If you lose or accept, the fee stays charged. The page does not say whether the original processing fee is returned, so check your payout line items.

Is it cheaper to accept than to fight a chargeback?

Not always. On Shopify, a lost fight costs the same cash as accepting, so fighting adds only your time. On Stripe, a lost fight adds the £20 counter fee. Fighting pays when the chance of winning, times the amount recovered, beats your time and any counter fee. Our decision table works it through.

What is the annual cost of chargebacks?

Multiply the monthly cost by twelve. A store with 1,000 orders a month at a £55 average order and 10 lost disputes a month spends £650 a month, or £7,800 a year, before time. Winning some disputes lowers it. Use your own log, since no audited UK win rate exists to rely on.
