The Hidden Fee: Amazon's Currency Conversion Markup
When you sell on an Amazon marketplace denominated in a different currency than your bank account, Amazon offers to convert the funds for you via the Amazon Currency Converter for Sellers. Convenient? Yes. Cheap? No.
Amazon's Currency Converter for Sellers (ACCS) adds a markup of approximately 3-4% on top of the mid-market exchange rate. This markup isn't shown as a separate line item - it's baked into the exchange rate. What makes this particularly insidious is that most sellers never see it broken out separately. Your disbursement report shows a single converted amount in your home currency - there is no line for "currency conversion fee." You have to manually compare the rate Amazon used against the mid-market rate on that day to see the true cost.
For a seller generating EUR 10,000 per month in UK sales, the ACCS markup represents EUR 300-400 per month in hidden fees. Over a year, that is EUR 3,600-4,800 - more than enough to fund an alternative conversion service that charges a fraction of that amount.
When Does It Apply?
Currency conversion hits EU sellers in these scenarios:
- EUR-based seller selling on Amazon.co.uk (GBP → EUR conversion)
- GBP-based seller selling on EU marketplaces (EUR → GBP conversion)
- Any seller selling on Amazon.se (SEK → EUR/GBP conversion) - check your SEK settings in Seller Central DE
If you sell on Amazon.de, .fr, .it, .es, .nl, .pl, .be - and your bank account is in EUR - no conversion needed for these marketplaces. This is one of the advantages of being an EUR-based seller in the EU: seven of the nine EU Amazon marketplaces operate in EUR, meaning you only face conversion on UK (GBP) and Sweden (SEK).
However, for sellers based in the UK (GBP) or non-EU countries, every EU marketplace sale involves conversion, making the cost much more significant. A UK-based seller doing EUR 50,000 per month in EU sales through Amazon's converter loses approximately EUR 1,750-2,000 monthly to conversion fees alone.

The Real Impact
Let's calculate the cost on a EUR 30 product sold on Amazon.co.uk:
- UK selling price: GBP 26 (approximate equivalent)
- Amazon's conversion rate: Mid-market minus 3.5%
- You receive: ~EUR 29.10 instead of EUR 30.16
- Hidden cost per sale: EUR 1.06
On 50 UK sales per day: EUR 53/day = EUR 1,590/month lost to currency conversion. Over a year, that is EUR 19,080 - a substantial sum that could fund significant inventory expansion, marketing campaigns, or simply flow straight to your bottom line.
Many sellers are unaware of this cost because Amazon does not break it out as a separate fee. In your payment reports, you simply see the converted amount in EUR. Without manually comparing Amazon's exchange rate to the mid-market rate on the same day, the markup is invisible. This opacity is by design - it is more convenient for sellers to not think about conversion, which means Amazon retains the full 3-4% margin on every cross-currency transaction.
Alternatives: Amazon vs Your Bank vs Wise/Payoneer
| Method | Conversion Cost | Speed | Convenience |
|---|---|---|---|
| Amazon ACCS | 3-4% | Instant | Highest |
| Traditional bank | 1-3% + flat fee | 2-3 days | Low |
| Wise (TransferWise) | 0.4-0.7% | Same day | Medium |
| Payoneer | 0.5-2% | Same day | Medium |
Recommendation: Use Wise or Payoneer for currency conversion. You can update your disbursement settings directly in Seller Central under Payment Settings. Receive GBP into your Wise GBP account, convert at near mid-market rates, transfer to your EUR bank account. The savings on 50 daily UK sales: ~EUR 1,200/month.
Setting up Wise for Amazon disbursements takes about 15 minutes. You create a Wise business account, obtain GBP account details (sort code and account number), and enter these in your Seller Central payment settings for the UK marketplace. Amazon then disburses your UK earnings in GBP directly to your Wise account, where you convert to EUR at near mid-market rates (typically 0.4-0.7% fee). The entire process is automated once configured - no manual intervention needed for each disbursement cycle.
For sellers also active on Amazon.se, the same approach works with SEK. Wise supports SEK accounts, and the savings on Swedish sales can be proportionally even larger due to the SEK/EUR conversion spread Amazon applies.
How This Affects Your Repricing Min Price
If you use Amazon's currency converter, your UK min price must include the 3-4% conversion fee:
UK Min Price = (EK + UK FBA + Shipping) / (1 - Referral%) / (1 - UK VAT 20%) / (1 - 3.5% FX fee) + Margin
This means your UK min price should be approximately 3.5% higher than it would be without conversion fees. For a product with a EUR 18 UK min price before conversion costs, the adjusted min price becomes approximately EUR 18.63. This may seem like a small difference, but on competitive ASINs where the BuyBox price sits near your floor, that EUR 0.63 buffer can make the difference between a profitable sale and a loss.
If you use Wise/Payoneer, the buffer drops to ~0.5-1%, significantly reducing the min price adjustment needed and making your UK prices more competitive while maintaining the same margin protection.
Setting Marketplace-Specific Min Prices Accounting for FX
In arbytrage.io, when calculating your UK min prices:
- Start with your purchase price in EUR
- Add UK-specific FBA fees (convert from GBP to EUR at current rate)
- Factor in UK VAT (20%)
- Add your currency conversion fee buffer (3.5% for Amazon, 0.5% for Wise)
- Add your target margin
Review monthly when GBP/EUR rate moves more than 2%.
Consider a practical example: You sell a yoga mat at GBP 22.99 on Amazon.co.uk. Your purchase price is EUR 8.00, UK FBA fee is GBP 3.80 (approximately EUR 4.40), and UK VAT is 20%. Using Amazon's converter at 3.5% markup, your net EUR revenue is approximately EUR 25.60 instead of EUR 26.53 at the mid-market rate. After deducting purchase price, FBA fees, and referral, your margin is EUR 2.85. Using Wise at 0.5% markup, the same sale yields EUR 3.68 margin. That is EUR 0.83 more per sale - a 29% margin improvement purely from changing your conversion method. On 150 monthly UK sales of this product, you earn EUR 124.50 more per month or EUR 1,494 per year.
Factor FX costs into your repricing rules - stop giving away margin to hidden fees.

Frequently Asked Questions
How much does Amazon charge for currency conversion?
Amazon's Currency Converter for Sellers (ACCS) adds approximately 3-4% on top of the mid-market exchange rate. This markup is embedded in the conversion rate and not shown as a separate fee, making it easy to overlook. To determine your actual conversion cost, compare the rate Amazon applied (visible in your disbursement report) against the mid-market rate on xe.com for that same day. The difference is your true conversion fee. Most sellers who perform this comparison are surprised to find the markup is consistently at the higher end of the 3-4% range.
Can I avoid Amazon's currency conversion fees entirely?
Yes. Use services like Wise or Payoneer to receive payments in the local currency (e.g., GBP for UK sales) and convert at near mid-market rates. This can reduce your conversion cost from 3-4% to under 1%. The setup process involves creating a local currency account with the service provider and entering those account details in your Seller Central payment settings. Once configured, all disbursements from that marketplace go directly to your local currency account, bypassing Amazon's converter entirely.
Does currency conversion affect my repricing min price?
Absolutely. If you use Amazon's converter, your UK min price should be approximately 3.5% higher to account for the hidden fee. If you use Wise or Payoneer, you only need a 0.5-1% buffer. Failing to account for this is a common cause of negative margins on cross-currency sales. Many sellers discover this issue only after reviewing their profit and loss for the quarter and finding that UK sales were significantly less profitable than expected despite similar gross prices.
Which EU marketplaces involve currency conversion?
For EUR-based sellers, only Amazon.co.uk (GBP) and Amazon.se (SEK) involve conversion. All other EU marketplaces (DE, FR, IT, ES, NL, PL, BE) trade in EUR with no conversion needed. For Polish zloty (PLN) concerns: Amazon.pl operates in EUR for seller disbursements to EUR-based bank accounts, so no conversion is needed despite Poland's local currency being PLN. Amazon handles the PLN to EUR conversion internally without charging sellers the ACCS markup.
