Payment Processing · Buyer guide
A chargeback has two costs. The first is the sale itself: the card issuer takes the disputed amount back from your processor, your processor takes it from you, and if you lose, it stays gone. That part is the same everywhere. The second is the fee your processor charges for handling the dispute, and that part is not the same anywhere. It ranges from nothing to $30, it is sometimes returned if you win and sometimes not, and at one processor it now comes in two parts. The card networks set the rules for how disputes are decided; the fee is the processor's own, which is why the answer to 'what does a chargeback cost' depends entirely on whose fee schedule you are reading.
We read nine of them, all as published in September 2026 for US merchants, and put them on one basis: a $100 sale disputed by the cardholder, in three outcomes — you accept it, you fight it and lose, you fight it and win. This piece is about the fee. For what happens when disputes become frequent enough that the networks take an interest, see our piece on chargeback monitoring programmes, and for finding the fee on your own statement, how to read a merchant processing statement.
The mechanics are worth knowing because they decide when the cost lands, not just how much it is. Stripe's documentation describes the standard pattern: when the cardholder's bank opens a dispute, the network debits the processor, and the processor 'debits the disputed amount, plus a dispute fee, from your Stripe account'. Those funds are held for the life of the dispute, which Stripe puts at 7 to 21 days for you to respond depending on the network, 60 to 75 days for the issuer to decide, and two to three months end to end. You cannot refund the customer outside the dispute while it is open. If the issuer finds for you, it returns the amount to the processor and the processor passes it back. If it finds for the cardholder, nothing further moves: the processor already credited the issuer when the dispute opened.
Two variations matter. Square places 'an immediate hold on the disputed funds by withholding funds from your Square balance or debiting your linked bank account', gives you seven days to respond, and on a win releases the funds 'including the processing fees'. Shopify Payments's help centre is in two minds about timing: its overview page says a chargeback 'is deducted from your next available payout', while its process page says 'the disputed amount and chargeback fee are withdrawn immediately' from your Shopify Payments account, and that a US merchant whose balance cannot cover it has the shortfall debited from their bank account outside the payout schedule. If you win, 'the full chargeback amount plus the chargeback fee is returned in your next payout after the decision is made'. American Express and Discover also run a preliminary 'inquiry' stage before a formal chargeback, and Stripe's documentation says an inquiry answered with satisfactory evidence, or settled with a full refund, is resolved 'without incurring a dispute fee'. An inquiry you ignore can become a chargeback you cannot win.
Stripe charges the most complicated fee of the nine, and the one most often misreported. Its US pricing page lists a dispute received fee of '$15.00 for each dispute you receive' and a dispute countered fee of '$15.00 for each dispute you respond to manually. You get this fee back for won disputes. You don't get this fee back for lost disputes.' The second fee applies to disputes initiated after 17 June 2025; Stripe's support notice says card network fees 'have increased across the full disputes lifecycle' and that the countered fee is waived when its Smart Disputes tool files the response. The documentation is blunt about the first fee: 'Unless otherwise stated in your Stripe contract, we never return the dispute received fee.' On a $100 sale: accept it, $115 gone; fight and lose, $130; fight and win, $15. If part of a dispute is won, Stripe returns that part and keeps both fees.
Square charges nothing. Its US support centre says 'there are no fees for dispute management services for chargebacks — we cover the fee for every dispute that we work together to challenge'. Accept, $100; fight and lose, $100; fight and win, nothing, and the original processing fee comes back with the sale. Square's Australian fee page says the same. The cost of that policy is elsewhere in the relationship — Square's rate is a flat 2.6% plus 15 cents in person — but on disputes alone it is the cheapest schedule here, and the only one where fighting a dispute has no downside.
PayPal's merchant fee page, last updated on 1 September 2026, lists three fees, and which one you pay depends on how the payment was made. For a payment made through a buyer's PayPal account or PayPal guest checkout, there is a Standard Dispute Fee of $15 and a High Volume Dispute Fee of $30. The user agreement says the fee is 'deducted from your PayPal account after the claim is decided', and that the standard fee is not charged for disputes 'decided in your favor by PayPal or your issuer', for transactions PayPal deems to have met Seller Protection, for unauthorised-transaction claims, for cases resolved with the buyer before escalation, and for claims 'with a transaction value that is less than twice the amount of a Standard Dispute fee' — under $30. You are on the high-volume rate if your ratio of item-not-received and not-as-described claims to sales was 1.5% or more over the previous three full calendar months and you had more than 100 sales; the win exemption does not apply to it, and PayPal may ask for a remediation plan. Then there is the third fee: for card transactions 'not processed either through a buyer's PayPal account or through a PayPal Guest Checkout' — a card taken through PayPal's own card processing — a chargeback costs a $20 chargeback fee, which 'will apply regardless of whether the buyer is successful'. On a $100 PayPal-checkout sale at the standard tier: accept, $115; lose, $115; win, nothing. On a directly processed card: $120, $120, $20.
Braintree, PayPal's enterprise gateway, prices cards at 2.89% plus 29 cents and lists 'Chargeback: 15.00 USD' on its fee page. The page says nothing about returning it on a win, and its statement that transaction fees 'will not be returned for refunded transactions' is about refunds, not disputes — so on the published terms, assume $15 whatever the outcome and ask your account manager to confirm in writing. Braintree sells cover on top: Chargeback Protection 'starting at 0.4% per transaction' and Effortless Chargeback Protection from 0.6%, with eligibility set out in the Payment Services Agreement.
Helcim states its fee as '$0 for cases resolved in your favor' and '$15 if lost'. That is the same net result as a refunded fee, but it is charged the other way round: nothing is taken until the case is decided against you. Helcim's card pricing is interchange-plus — 0.40% plus 8 cents in person and 0.50% plus 25 cents online at up to $50,000 a month — so it is also the only schedule here where the underlying sale is priced at cost plus a margin rather than a flat rate. A $100 sale: accept, $115; lose, $115; win, nothing.
Shopify Payments charges $15 in the United States, and its help centre says 'if you win the chargeback, then the fee is returned to you'. The amount and the fee come out of your Shopify Payments balance when the chargeback opens, and go back in the next payout after a win. WooPayments, which runs on Stripe's rails but sets its own fee schedule, charges $15 per dispute at its 2.9% plus 30 cents US rate, and its documentation says the fee 'is refunded to you automatically should you challenge and win the dispute'. Note the condition: a dispute you do not challenge keeps the fee. Both work out to $115 on a loss and nothing on a win.
Squarespace Payments charges $20 in the United States — higher than the $15 it charges in Canada, Australia, New Zealand, the UK and the eurozone in local currency — and its help centre says the fee 'is immediately debited from your Squarespace Payments account balance' when the dispute is opened and 'if you win the dispute, the fee is refunded'. It adds two details the others do not spell out: that American Express and Discover only deduct the fee if you lose an inquiry, and that the response deadline 'varies by card brand but is typically 20-45 days'. A $100 sale: $120 on a loss, nothing on a win.
QuickBooks Payments is the outlier at the expensive end. Intuit's help article says 'there's a $25 fee for chargebacks to cover our processing costs', and, on a win, 'any returned money won't include the $25 processing fee'. So a $100 sale costs $125 on a loss and $25 on a win, the worst won-dispute outcome of the nine. Intuit sells its way out of that: Payments Dispute Protection, priced 'as low as 0.99%' of every card transaction, covers up to $10,000 per chargeback and $25,000 a year, waives the $25 fee while you are enrolled, and excludes ACH, PayPal, Venmo and Affirm payments and anything disputed before you signed up.
Put the nine on the $100 basis and three groups appear. Fighting and winning costs nothing at Square, Helcim, Shopify Payments, WooPayments, Squarespace Payments and PayPal's standard tier; it costs $15 at Stripe and, on the published terms, Braintree; it costs $20 on a card taken through PayPal's direct card processing and $25 at QuickBooks Payments. Fighting and losing costs $100 at Square, $115 at Helcim, Shopify, WooPayments, PayPal standard and Braintree, $120 at Squarespace and on PayPal direct card, $125 at QuickBooks and $130 at Stripe. And accepting a dispute without a fight costs $100 at Square and Helcim, $115 at Stripe, Shopify, WooPayments, Braintree and PayPal standard, $120 at Squarespace and PayPal direct card, and $125 at QuickBooks.
Two things follow. The first is that the fee is a small number next to the sale, so a processor's dispute fee should almost never decide who you process with; a difference of 0.1 percentage points on your rate is worth more than any of these fees on all but the smallest businesses. The second is that the refund rule changes the maths on whether to fight. Where the fee comes back on a win, the only cost of a losing response is your time. At Stripe, a manual response is a $15 bet that you will win; Stripe's own guidance is to refund pre-dispute fraud warnings on charges 'roughly less than or equal to your dispute fee', because at that size the fee is most of what is at stake.
Most of the third-party comparison pages we read while researching this say Stripe charges $15 and refunds it if you win. Whatever the arrangement was before June 2025, it is not what Stripe's pricing page says now, and a merchant who reads a blog rather than the fee page will find $30 missing after a lost response and $15 missing after a won one. The same pages tend to give PayPal a single number, usually $20, which is the chargeback fee on directly processed cards and is neither the standard nor the high-volume dispute fee that most PayPal sellers actually pay. Fee schedules change and the processors do not announce the changes loudly. The fee page, dated, is the only source worth quoting, and every figure above is from one.
If you want to check your own processor, look for three things on its fee page or in its agreement: the amount, whether it is charged when the dispute opens or when it is decided, and whether it comes back if you win. If the page does not say, ask in writing, and keep the answer with the agreement.
