Exchange Rate Margin Calculator

Measure the margin between the market rate and the rate you were offered.

Provider margin

How it works

The gap between the two rates is expressed as a share of the market rate, then applied to your amount to show what the spread costs.

Example

An offered 1.052 against a market 1.085 is a 3.04% margin, costing 132.00 on 4,000.

This tool is for estimation and education, not financial, tax, or legal advice.

Frequently asked questions

Do these tools fetch live rates?

No. You enter the rate you were quoted, which is the one that will actually apply to you.

Does the calculator send my numbers anywhere?

No. The calculation runs locally in your browser.

Why does my bank's rate differ from the market rate?

The difference is the provider's margin; the exchange rate margin tool measures exactly that.
