Currency conversion, with the spread made visible.

Enter an amount and the mid-market rate, then add the margin your provider charges to see what you actually receive rather than what the rate implies.

Inputs

The formula used

received = amount × rate × (1 − margin) − fixed fee

Rates must be entered manually because this page makes no network requests. Take the mid-market rate from a reference source, then add your provider's margin.

No live rates are fetched — nothing on this page contacts a server. Enter the current rate yourself from a source you trust.

The spread is the fee.

Providers advertising no commission make their money on the margin between the mid-market rate and the rate they give you, typically one to three per cent and occasionally far more at airport counters. The effective-rate figure above is the only honest basis for comparison, because a low fixed fee with a wide spread is usually more expensive than the reverse.

Questions about currency

What is the mid-market rate?
The midpoint between buy and sell rates in the interbank market. It is the rate quoted in the news and the one no retail customer actually gets.
Why is the airport rate so poor?
Captive demand, low volumes and high operating costs. Margins of five to ten per cent are common, which is several times the online alternative.
Should I let the merchant convert?
Usually not. Dynamic currency conversion at the point of sale typically carries a worse rate than your own card issuer's.

A calculator handles the arithmetic. It cannot teach you the method.

If the number is not the part you are stuck on, that is what the service is for — a specialist who explains the working, not just the answer.

These are coursework tools. Nothing here is financial advice, no figure accounts for tax rules in your jurisdiction, and no result should be relied on for a real borrowing or investment decision.
