Reference-rate benchmark
The user supplies a destination-units-per-send-unit reference rate. We multiply it by the send amount to create a transparent no-fee benchmark. This is a comparison device, not a claim that a consumer could transact at that rate.
All-in cost estimate
For a quote, the tool subtracts the recipient amount from the reference benchmark. It converts that difference back to the send currency at the reference rate, then adds upfront and receiving fees supplied by the user. No provider data is preloaded.
Rounding and uncertainty
Displayed money is rounded to two decimal places while calculations retain JavaScript number precision. Intermediary charges and final bank conversion may be unknown. Results should be treated as estimates and reconciled with the provider's final disclosure.

From user input to result
Create the benchmark
Multiply the send amount by the reference rate.
Measure the shortfall
Subtract the amount expected to reach the recipient.
Return to one currency
Convert the shortfall to the send currency and add stated fees.
Keep uncertainty visible
Show unknown route charges as unknown instead of guessing.
The core transfer relationships
- Benchmark recipient amount
- send amount × reference rate
- Rate shortfall
- benchmark amount − quoted recipient amount
- Estimated send-currency cost
- rate shortfall ÷ reference rate + stated fees
- Required principal for a target
- (recipient target + receiving fee) ÷ customer rate
- Linear route cost
- flat fee + amount × (variable fee % + FX markup %)
- Annual account value
- spread savings + payment savings − annual account fees
