How the Currency Profit Calculator works
Suppliers in China, Europe or India quote in their own currency; you sell in dollars (or another marketplace currency). This calculator converts the supplier cost at a static rate (or a rate you enter from today's bank quote), then runs the full FBA profit calculation.
Because exchange rates move, it also shows profit if the supplier currency strengthens or weakens by 10%, and the rate at which the product stops being profitable.
Formula
- Converted cost = Supplier cost × Rate (selling currency per 1 supplier currency)
- Net profit = Price − Converted cost − Inbound shipping − Amazon fees − Ads − Returns − Misc
- Break-even rate = (Converted cost + Net profit) ÷ Supplier cost
Example
¥45 converts to about $6.20; after fees the unit nets roughly $10, and a 10% stronger yuan costs about $0.62 of that.
Frequently asked questions
Where does the exchange rate come from?
A static table maintained by the FBAZone admin (Settings → fx.rates). It is not a live feed; enter your bank's quote in the manual rate field for an exact figure.
Which rate should I use for planning?
Your payment provider's actual rate including its spread, which is usually 1–3% worse than the mid-market rate.
