The dollar amount above which fighting pays off
With the sale amount, the dispute fee, and the odds of winning based on the reason given, you calculate the number above which you fight a chargeback and below which you let it go.

You get an $18 chargeback. The reason the bank gave is 'I don't recognize this charge.' You have a screenshot of the booking, the IP address it came from, and the confirmation email the customer opened. You could put the case together in half an hour.
That half hour isn't free, and responding to the dispute can cost you a fee too, one you lose if you don't win. What's missing is the exact number: the sale amount above which it's worth risking that time and that fee, and below which it's better to write the charge off as a loss.
Almost nobody runs these numbers before the first case shows up. They fight every chargeback on principle, or let them all slide out of sheer fatigue. Both habits get expensive, each in its own way.
Picture a month with six chargebacks ranging from $15 to $40. If you fight all six on principle and win only two, you've spent three hours and several fees to recover a fraction of what you lost on the other four. If you let them all slide out of fatigue, you've given away up to $240 without checking whether any of them already had delivery proof saved and could've been won in five minutes. Setting a cutoff avoids both drains.
A fixed cost, a variable amount
Every chargeback comes with fees that stay the same whether the sale was $12 or $300, and each payment processor charges them its own way. With Stripe, it's $20 just to receive the dispute, charged whether you fight it or not and never refunded, plus another $20 to contest it by responding, which you get back if you win. With PayPal, the standard dispute fee is $14 and isn't charged if the dispute is resolved in your favor. The fee for receiving the dispute is already paid no matter what you do, so it doesn't factor into your decision: what matters is the fee you risk by responding.
Then there's your time. Gathering screenshots, writing the response, and uploading it to the disputes dashboard takes a while. If it takes you half an hour and your time is worth $20 an hour, the real cost of fighting isn't just the $20 fee to contest it: it's $30.
That number, fee plus time, is your cost of fighting. Compare it to what you can recover before you open the case, not after you've already built it.
- You know the exact cost before deciding whether it's worth it
- It's only worth fighting when the amount already covers that fee plus your time
- Fighting a case you expect to win doesn't add a fee cost, just your time
- It's worth fighting low amounts if the reason is one you almost always win
- If you lose, you pay the fee and the sale amount at the same time: it's a double hit
- It's worth checking your processor's terms, since some change the fee based on how many disputes you rack up in a month
Which I choose: With a fee only if you lose, lower your cutoff for cases with a strong reason, like 'I don't recognize this charge' backed by an IP address and delivery confirmation. With a fee charged every time, raise your cutoff and save your fight for amounts that already cover that fee before you even look at the reason.
The math that decides
With the fixed fee and your time valued in dollars, you already have your cost of fighting. Put it next to the amount of every chargeback that comes in, before you decide anything.
The reason changes the cutoff, not just the amount
The $30 cutoff isn't fixed. It goes up or down depending on your odds of winning, and those odds come down to the chargeback's reason code. An 'I don't recognize this charge' case backed by a saved IP address and delivery timestamp has good odds; and if the payment passed the customer's bank verification (3D Secure), Stripe says a fraud dispute typically won't even reach you, since liability usually shifts to the card-issuing bank. A 'service quality' case is much harder to win, because the bank has no way to check whether a haircut or a physical therapy session was done well.
The evidence you gather depends on what you sell (an appointment, an order, or access to something). But whatever it is, having it ready ahead of time is what brings your fighting time down close to zero, and that pushes the cutoff lower: putting a case together in ten minutes because you already have the IP address and signed receipt saved is nothing like scrambling for screenshots after the bank's notice has already landed.
The full calculation multiplies the amount by that probability, and you compare the result to the cost. A $90 sale with a reason you win eight times out of ten is worth, in practice, $72 in expected value: fight it with room to spare. That same sale with a reason you win two times out of ten is worth $18, and at that point the cost of fighting no longer pays off.
You don't have to guess those odds every time. Your processor's disputes dashboard keeps a history of past cases, won and lost, with the reason for each one. If you've been using it for six months, you already have your own number: how many 'I don't recognize this charge' cases you've won, how many 'service quality' cases you've lost. That number beats any general average, because it's yours, based on how you sell and how you keep records.
you're paying a guaranteed cost for an unlikely payoff
- The cost of fighting is fixed: the dispute fee plus your time valued in dollars
- The cutoff isn't a fixed amount: it rises or falls based on the odds of winning that the reason sets
- You now have a written rule to decide without having to think it through every time a case comes in
- You know whether your payment processor's fee gets charged every time or only when you lose, and how that shifts the cutoff
Test yourself
Answer before opening each one. If one gives you trouble, go back to the section that explains it.
1. You get a $22 chargeback for 'I don't recognize this charge,' and you have the IP address and delivery confirmation saved.
You fight: with that evidence, the reason has good odds and you already have it ready, so the real time cost is minimal; and if your processor refunds the response fee when you win, what you're risking is small next to the $22.
2. A customer files a $130 chargeback for 'service not as described,' after a session you did without a photo or signed work order.
Let it go: this reason code is one you almost never win without documented proof, so even though the amount is high, the odds of collecting are low and the cost of fighting won't pay off.
3. Your processor only charges the response fee if you lose, and you get a $20 chargeback for a reason you usually win.
You fight: since that fee is only paid if you lose, your real cost if you win is just your time, and with a reason you almost always win, the expected value already beats that, even though it's below the cutoff you'd use with a processor that always charges.
That number tells you when to fight a single case. It doesn't mean winning them all is free: every chargeback filed against you counts against your account even if you win, and there's a limit to how many you can rack up before they cut off your ability to take card payments.
