## Two costs, one number

Every transfer has two costs. The margin: the gap between the rate you get and the mid-market rate, usually 0% to 4%. The fee: a flat amount, a percentage, or both. This calculator combines them into the amount received and the effective cost percentage, so different providers compare honestly.

## Worked example

You send **$1,000** USD to EUR at a quoted rate of **0.90** with a **1%** margin and a **$4.99** fee. After the margin the rate is 0.891; after the fee, the recipient gets **886.51 EUR**. Effective cost: **1.5%**. A "zero fee" provider with a 3% margin would cost twice as much.

## Finding the mid-market rate

Search your currency pair and compare the quoted rate to the mid-market rate shown by a neutral source. The percentage gap is the margin. Wise, banks, and PayPal all quote different margins; the fee line is only half the story.

## Why the rate field is editable

Rates move constantly, so the page does not fetch live rates. Enter the rate your provider quotes right now, or the mid-market rate plus the margin you expect. The pair dropdown fills a recent approximate rate as a starting point.

## Frequently asked questions
### What is the true cost of an international transfer?

The margin (the gap between your rate and the mid-market rate) plus any flat or percentage fee, expressed as one percentage of the amount sent. That is the only number that lets you compare providers.

### How do I find the exchange rate margin?

Compare the quoted rate to the mid-market rate for the pair; the percentage gap is the margin. Typical margins: 0% to 1% for specialist services, 2% to 4% for banks and PayPal.

### Is a zero-fee transfer really free?

Often the margin. A provider advertising zero fees with a 3% margin costs more than a $5 fee with a 0.5% margin on most amounts. Always compute the effective cost.

### Are the exchange rates live?

No. The pair dropdown fills a recent approximate rate as a starting point, but rates move constantly. Enter the rate your provider quotes for an exact answer.

### Does the transfer size change which cost matters?

The flat fee dominates small transfers; the margin dominates large ones. Splitting or combining transfers changes which cost matters most.

### What is the mid-market rate?

Mid-market rate is the midpoint between buy and sell rates on the open market: the fairest reference. Your provider's rate will always be worse; the gap is their cut.

### What do I need to enter?

Enter the amount, pick a currency pair, enter the quoted rate, margin, and fees. All math happens on the page.

### Is my data sent anywhere?

No. The calculator runs entirely in your browser. You can disconnect from the internet after the page loads and it still works.
