Formula Used
Definitions
SA= Send amount in the source currency.FF= Fixed fee in the source currency.PF= Percent fee (% ofSA).MMR= Mid‑market rate (1 FROM = MMR TO).PR= Provider rate. If not given and marginm%is provided, thenPR = MMR × (1 − m/100).
Fees before conversion
FeesBeforeFX = FF + SA × PF/100 NetConverted = max(SA − FeesBeforeFX, 0) ReceivedTO = NetConverted × PR YouPayFROM = SA IdealTO = YouPayFROM × MMR EffectiveRate = ReceivedTO / YouPayFROM TotalLossTO = IdealTO − ReceivedTO LossPct = 100 × (TotalLossTO / IdealTO)
Fees charged on top
FeesOnTop = FF + SA × PF/100 NetConverted = SA ReceivedTO = NetConverted × PR YouPayFROM = SA + FeesOnTop IdealTO = YouPayFROM × MMR EffectiveRate = ReceivedTO / YouPayFROM TotalLossTO = IdealTO − ReceivedTO LossPct = 100 × (TotalLossTO / IdealTO)
This calculator does not fetch live rates. Enter a benchmark rate and any quoted rate to compute the all‑in effective rate and total cost.

How to Use
- Enter the two currency codes and the amount you intend to send.
- Provide a benchmark mid‑market rate for the pair.
- Either enter a quoted provider rate or supply an expected margin percentage; the tool will compute the missing value.
- Set fixed and percent fees and choose whether fees are deducted before conversion or charged on top.
- Click Calculate to view the summary, then optionally Calc & Add Row to build a comparison table.
- Export your table to CSV or PDF for records and side‑by‑side provider comparisons.
FAQs
It is the recipient amount divided by the total you pay in the source currency. It blends the quoted rate with all fees into one comparable figure.
The mid‑market rate is a neutral benchmark often between wholesale buy and sell prices. Comparing against it highlights hidden margins embedded in provider quotes.
Either works. If you enter a provider rate the tool derives the margin. If you enter a margin it derives a provider rate from the benchmark.
Many providers deduct fees before conversion but some charge on top. Use the fee mode toggle to mirror how your provider bills.
It means the fixed and percent fees exceeded your send amount when fees are deducted before conversion. Increase the send amount or switch to fees on top.
No. To ensure transparency this tool requires you to enter a benchmark rate and any quoted rate. That keeps the math clear and portable.
