Before you rely on this

Shows the mid-market rate. Banks, card networks and bureaux add a spread on top and charge transfer fees separately, so the amount you actually receive is lower. Values are as of the time of lookup and are not dealable quotes.

Tool Overview & Key Purpose

Converts amounts using the mid-market rate across 160-plus currencies. The mid-market rate is the reference banks trade with each other at — the same number quoted in the news, and not the number you get at the counter. Reading it with that gap in mind is the point of this tool.

Step-by-Step Usage Instructions

1STEP 1

Pick the source and target currency, enter an amount, and the conversion appears immediately.

2STEP 2

Use the swap button to reverse the pair and check the conversion the other way.

3STEP 3

Check the lookup timestamp — rates move constantly, so when the number is from matters as much as the number.

4STEP 4

To estimate what you will actually receive, subtract the bank or card spread (typically 1–3%) from this figure.

Real-World Scenarios & Practical Cases

3 Practical CasesScenario #1

Estimating what an overseas purchase will cost

For a $120 item paid by card, the mid-market conversion is the floor of what you will be billed. A foreign transaction fee (often around 1%) and the exchange spread sit on top of it.

A statement 2–3% above the converted figure is the spread, not an error.Scenario #2

Comparing moments to exchange before a trip

Checking at the same time of day over several days shows whether the rate is moving your way. Short-term rates are not predictable, though, so splitting the amount across a few exchanges reduces the risk of timing it badly.

Airport bureaux carry the widest spreads — use them only when you have no alternative.Scenario #3

Working backwards from an amount someone must receive

Converting in reverse from the amount the recipient needs gives the minimum you must send. Add the transfer fee and any correspondent bank charges on top to get the real figure.

Correspondent charges appear or not depending on the routing — ask your bank whether it offers a full-amount-to-recipient option.Rate source and refresh

Converted = amount × (target base rate ÷ source base rate)
A cross rate: the two currencies are linked through a base currency, usually USD.
Actual proceeds ≈ converted × (1 − spread) − transfer or card fees

Pro Tips & Key Considerations

A gap between the news rate and your bank’s board rate is the spread, not an error. The bank’s "base rate" line is the one closest to the figure shown here.FX markets close at weekends and on holidays, so the rate stops updating — Friday’s close can still be showing on Monday.When a card terminal abroad offers to charge you in your home currency (dynamic currency conversion), it is usually the worse deal — choose the local currency.Many countries share a currency symbol ($ covers the US, Canada, Australia, Singapore and more). Confirm by currency code, not symbol.
