Currency Converter

The currency converter uses live exchange rates to instantly convert between more than 30 major world currencies. Updated every 60 seconds, it's the most accurate free currency tool for travelers, international shoppers, freelancers invoicing across borders, and forex traders needing quick reference rates.

What this calculator does

Exchange rates are fetched in real time via the Frankfurter API. Supported currencies include EUR, USD, GBP, JPY, CHF, CAD, AUD, NZD, SEK, NOK, DKK, PLN, CZK, HUF, BTC and more.

How it works

Currency exchange rates fluctuate continuously due to macroeconomic factors including interest rate decisions, inflation data, trade balances, and geopolitical events. Always check rates close to the time of your transaction.

When to use this calculator

This calculator earns its keep at decision points: before accepting a loan, comparing investment platforms, or negotiating salary. The difference between the headline figure and the true cost or return is only visible with accurate arithmetic.

Common mistakes

Many financial calculation errors stem from omitting ancillary costs: fees, taxes, insurance, or maintenance. The headline figure (interest rate, monthly payment) is rarely the complete cost of a financial product.

Real-world scenarios

An employee receives a counter-offer from another employer: a £4,000 salary increase but no pension contribution versus the current role's lower salary with 8% employer pension. Running both through the finance calculator shows the true net financial value of each offer.

Formula

Currency Conversion Formula

Amount in Target Currency = Amount × Exchange Rate (base → target)

Exchange rates represent how many units of the target currency equal 1 unit of the base currency. EUR/USD = 1.08 means €1 =

.08.

Worked example

Convert €1,500 to US Dollars with an EUR/USD rate of 1.085.

  1. Identify: Amount = €1,500, Rate = 1.085
  2. Multiply: 1,500 × 1.085 =
    ,627.50

Result: €1,500 =

,627.50 at a rate of 1.085

Frequently asked questions

Are exchange rates live?

Yes, rates are updated every 60 seconds via the Frankfurter API, reflecting the mid-market interbank rate.

Why is my bank rate different?

Banks and exchange desks add a margin (1–4%) to the mid-market rate shown. Services like Wise or Revolut offer rates closer to the mid-market rate.

Can I convert cryptocurrency with this tool?

Yes, Bitcoin (BTC) and major cryptocurrencies are supported alongside fiat currencies.

What is the mid-market exchange rate?

The mid-market rate is the midpoint between buy and sell prices on the global forex market. It's the fairest benchmark rate, though you rarely get it at banks or exchanges.
