How Amazon Currency Converter for Sellers actually prices its service
If you sell on Amazon marketplaces that pay out in a currency different from your home bank account, Amazon offers to handle the conversion for you automatically through a service called Amazon Currency Converter for Sellers, usually shortened to ACCS. It's convenient, it's the default path most sellers end up on without ever choosing it deliberately, and it is not free, even though nothing about the payout screen tells you that in plain language.
The stated fee typically falls somewhere between 0.70% and 1.50%, depending on your annual payout volume run through the converter, higher-volume sellers get better rates, smaller sellers pay closer to the top of that range. There's one flat exception worth knowing specifically, sellers receiving payouts in Japanese Yen pay a flat 2.0% regardless of their volume tier, no sliding scale applies.
Those percentages sound modest in isolation. They're also not the whole story, which is the part that costs sellers real money without them noticing.
Why this fee is so easy to miss on your own P&L
Most fees Amazon charges show up as a discrete line item somewhere you can find it, referral fees, FBA fees, storage fees, all itemized. Currency conversion doesn't work that way. ACCS doesn't charge you a visible fee and then apply the real market exchange rate. Instead, it bakes its markup directly into the exchange rate itself, the rate you see applied to your payout is already worse than the actual mid-market rate by roughly the amount of the fee. There is no separate invoice, no line labeled "currency conversion fee," nothing that shows up as a deduction you can point to.
That structure is exactly why this is one of the most commonly overlooked costs on an international seller's P&L. You see a payout amount, it looks reasonable, and there's no obvious prompt to go check it against anything else. The cost is real, it's just invisible by design rather than by accident.
Think about how differently you'd treat this if Amazon itemized it. A line item labeled "currency conversion fee: 1.2%" sitting next to your referral fee and FBA fee lines would get noticed, questioned, and probably shopped around within a year. Because it's folded into the exchange rate instead, most sellers go their entire selling history on a given marketplace without ever running the comparison that would surface it. The fee isn't hidden because Amazon is doing anything unusual by industry standards, banks and payment processors have used spread-based currency margins for a long time, it's hidden because nothing in Seller Central's reporting prompts you to go looking for it.
Independent estimates suggest that once you account for the unfavorable exchange rate itself, not just the advertised percentage, the real effective cost to a seller's profit can run as high as 3.5% on converted international sales. On thin-margin categories, that's not a rounding error, it's a meaningful chunk of what you thought you earned.
How to calculate what you're actually losing
You don't need anything sophisticated to find your real number, you just need to compare against a rate ACCS isn't the one quoting you. Pull the exchange rate Amazon actually applied on a specific payout date, it's visible in your payout report and transaction detail. Then look up the real market mid-market rate for that same currency pair on that same date, any independent source works for this, a bank's published rate or a financial data site.
- Find your ACCS-applied rate. In Seller Central, pull the payout report for a settlement period where a currency conversion actually occurred and note the exact rate used.
- Find the true mid-market rate for that date. Look up the same currency pair's mid-market rate for the same date from an independent source.
- Calculate the spread as a percentage. Subtract the ACCS rate from the mid-market rate, divide by the mid-market rate, and that percentage is your real effective cost on that conversion, likely higher than the stated ACCS fee range alone.
- Apply it across your annual converted volume. Multiply that percentage against your total annual payout volume that goes through currency conversion to see the real annual dollar cost, not just the per-transaction one.
Run this once and most sellers are surprised. It's rarely a number anyone budgeted for, because it was never presented as a number to budget for in the first place. Say your ACCS-applied rate comes out a little worse than the mid-market rate you looked up for that same day, once you translate that gap into a percentage and apply it against a full year of converted payouts from a marketplace doing meaningful volume, the annual dollar figure is usually large enough to change how you think about the problem, from "a fee I probably pay" to "a specific cost I can now decide whether to keep paying."
Do this exercise across a few different payout dates, not just one, since exchange rates and ACCS's applied spread both move day to day. A single data point can be an outlier in either direction. Averaging three or four dates spread across a settlement period gives you a more reliable read on your actual ongoing cost than a single snapshot.
The workaround: get paid in local currency instead of converting at all
The most direct fix isn't finding a cheaper converter, it's avoiding conversion entirely for marketplaces where that's possible. Amazon lets sellers add local-currency bank account details directly to their Seller Central account, so instead of Amazon converting your UK payout into dollars through ACCS, it just pays directly into a GBP-denominated account. Same idea applies to a Eurozone account for EUR payouts, and other supported currency and marketplace combinations.
Setting this up is a Seller Central account settings task, under your payment or deposit method settings, where you can add a bank account and specify its currency rather than relying on the default currency conversion path. Once it's added and verified, payouts for that marketplace route to that account in its native currency, and ACCS never touches that money, so there's no spread to lose in the first place.
This doesn't mean the money is now "free" of any conversion cost forever, if you eventually need to move those funds back to a home-country account in a different currency, you're still converting at some point, just not through Amazon and not automatically. But it puts you in control of when and how that conversion happens, instead of it happening silently on every single payout.
The setup itself is usually just opening (or already having) a bank account denominated in the marketplace's local currency and entering its account and routing details into the relevant deposit method section of Seller Central for that specific marketplace. It's a one-time task per marketplace, not something you have to touch again once it's confirmed, and Amazon typically verifies the account with a small trial deposit before switching your payouts over to it. The main friction is that opening a foreign-currency bank account isn't always trivial depending on your home country and banking relationships, which is exactly the gap that cross-border fintech services were built to close.
A seller active on Amazon UK, Amazon Germany, Amazon Japan, and Amazon Canada simultaneously can easily be paying the ACCS spread on four or five separate currencies at once without realizing it, simply because local bank details were only ever set up for the one marketplace they started on.
When a dedicated cross-border banking service is worth using
The local-currency account setup solves the problem for sellers who are comfortable holding funds in multiple currencies indefinitely, or who have a genuine local use for that currency, paying an overseas supplier in their own currency, for instance. It doesn't solve it for sellers who ultimately need everything consolidated back into one home-country currency and account.
For that second group, a dedicated cross-border payment or banking service built for exactly this use case is usually the better move over letting ACCS handle it. These services generally offer conversion rates in the 1% to 1.5% range, meaningfully better than ACCS's stated range and considerably better than the real effective cost once ACCS's hidden spread is accounted for. The mechanics are straightforward: instead of adding a local Amazon bank account, you add the fintech's provided local account details as your payout destination, Amazon pays into it in local currency, and the service converts and moves it to your home account at its own, more transparent rate.
The right choice comes down to your actual cash flow needs. If you need funds in dollars every month to run your business, a fintech service beats ACCS on cost with minimal added complexity. If you're building up genuine multi-currency operations, paying suppliers or running ad accounts in local currency, the plain local bank account might mean you don't need to convert some of that money at all.
A practical audit for multi-marketplace sellers
If you're selling across more than one Amazon marketplace, this is worth a real, deliberate review rather than something you assume is fine because nobody's complained. Go marketplace by marketplace and check three things, whether you're currently on ACCS by default or have local currency banking set up, what the calculated spread has actually cost you over the trailing twelve months using the method above, and whether your transaction volume in that marketplace justifies setting up either a local account or a fintech relationship versus just leaving it as is.
For a seller doing meaningful volume in even two or three non-home-currency marketplaces, this audit routinely uncovers a cost that's been running quietly for years, invisible precisely because Amazon never itemized it, sitting there the entire time as a permanent, compounding tax on international growth that nobody flagged until someone went looking.
Put a recurring reminder on this rather than treating it as a one-time fix. New marketplace launches, new currency payout defaults, and account settings that reset after a support interaction can all quietly put you back on ACCS for a currency you'd previously moved off of. A five-minute check each quarter, confirming that every active marketplace's payout method is still set the way you intended, costs you almost nothing and protects a savings you already did the work to capture once.
If you're active in six marketplaces but ninety percent of your international revenue comes from two of them, fix those two first. Chasing a perfect setup across every low-volume marketplace before addressing your highest-volume currency exposure is a common way this project stalls out without delivering the savings that actually matter.
