Forex Calculator
Our forex calculator converts any amount between major currency pairs and shows the total received after typical transfer fees — helping businesses, investors, and individuals understand the true cost of international currency conversion. For those moving larger sums, even small differences in the exchange rate can result in thousands of pounds of difference in the final amount received.
Forex / Foreign Exchange Calculator
Compare the true cost of converting currency. See exactly how much you lose to bank margins and transfer fees.
Live mid-market rates fetched from European Central Bank. Actual rates offered by your bank or transfer service will include a margin above the mid-market rate. UK high-street banks typically charge 2–4% above mid-market; specialist FX providers charge 0.3–1.5%.
How Forex Markets Work
The foreign exchange (forex) market is the largest financial market in the world, trading approximately $7 trillion per day. Exchange rates fluctuate continuously based on economic data, interest rate differentials, geopolitical events, and market sentiment. Businesses with international operations face forex risk — the risk that currency movements between invoicing and payment will change the sterling value of a transaction. Forward contracts, currency options, and natural hedging are strategies to manage this exposure. Use our Currency Converter to see the mid-market rate as a reference for evaluating any quote you receive from a bank or transfer service, and our Income Tax Calculator to model the tax position on any forex-related income.
Frequently Asked Questions
A forward contract locks in an exchange rate today for a currency conversion that will take place at a specified future date. Businesses use forward contracts to eliminate forex risk on known future payments — for example, a UK importer expecting a $100,000 invoice in 6 months can lock in the sterling cost today.
No — exchange rates are set by supply and demand in the global forex market. The Bank of England influences sterling through interest rate decisions and very rarely through direct market intervention.
A pip (percentage in point) is the smallest standard price movement in a currency pair — typically the fourth decimal place (0.0001). On GBP/USD at 1.2850, a 1-pip move changes the rate to 1.2851.
For individuals, currency gains on foreign currency bank accounts are generally not taxable unless speculative trading in nature. For businesses, forex gains and losses on trading transactions are taxable income or allowable expenses.
For personal use, use a specialist money transfer service for large amounts. For business use, open an account with a corporate FX provider and negotiate rates on volume. Avoid exchanging at airports, hotels, or high-street banks — these consistently offer the worst rates.
Enter the currency pair and amount for your transaction. The calculator shows the current mid-market rate and estimates the typical spread charged by different types of provider — banks, online transfer services, and cash bureaux. For regular international transfers, the annual cost difference between using a bank and a specialist transfer service can be significant on moderate transaction sizes. Forward contracts allow you to lock in today’s exchange rate for a future transaction — useful for businesses or individuals with known future foreign currency requirements such as property purchases abroad or regular overseas payments. The forward rate reflects the interest rate differential between the two currencies and may be better or worse than the spot rate depending on the currency pair.
