Currency Calculators
Cross Currency Converter
Build a cross rate for a pair nobody quotes directly by chaining two legs through an intermediate currency, with worked examples and direction checks.
Currency Arbitrage Calculator
Test three exchange rates for a triangular arbitrage loop, with the product formula, worked profit figures and why real spreads close the gap so fast.
Currency Conversion Fee Calculator
Reveal the fee hidden inside an offered rate by comparing it against the mid-market rate, with a spread cost table and where hidden spreads usually show up.
Currency Converter
Convert an amount between two named currencies at a rate you enter, with the quote direction explained and reciprocal rates for converting back again.
Currency Exchange Calculator
Convert an amount and get the reverse rate in one step, with a reciprocal rate table, a curve chart and why small rates swing their mirror image so much harder.
Exchange Rate Calculator
Convert an amount at an exchange rate you supply, with the direction of the quote explained and a worked table showing how the rate scales the result.
Foreign Transaction Fee Calculator
Work out the card surcharge added to a foreign purchase, with a fee table across the common card rates and why it stacks on top of the conversion spread.
Forex Pip Calculator
Work out what a single pip is worth from pip size, exchange rate and lot size, with standard, mini and micro lot values plus the yen pair pip difference.
Historical Exchange Rate Calculator
Compare an amount converted at two exchange rates and the percentage the rate moved, with worked examples and why the base rate always sets the percentage.
Purchasing Power Parity Calculator
Compare a market exchange rate against the rate implied by two basket prices, with the PPP formula, worked verdicts and why the gap tends to persist for years.
The Rate You See Is Rarely the Rate You Get
Advertised exchange rates and the rate actually applied to a transaction routinely differ — banks and card networks add a spread on top of the mid-market rate, and international transfers often carry separate fixed fees. These calculators work with real mid-market rates, spreads, and fees to show what a conversion actually costs.
Popular Currency Calculators
Ten tools cover conversion, forex trading, and cross-border cost:
- Currency Converter — converts between currencies using current exchange rates.
- Foreign Transaction Fee Calculator — estimates the extra cost card issuers add on international purchases.
- Forex Pip Calculator — calculates the monetary value of a pip movement for a given position size and currency pair.
- Purchasing Power Parity Calculator — compares what the same money actually buys across countries, beyond the raw exchange rate.
- Currency Arbitrage Calculator — checks for profitable rate discrepancies across three or more currency pairs.
Why the Mid-Market Rate Isn't What You Actually Pay
The mid-market rate is the midpoint between what banks buy and sell a currency for — it's the rate quoted on financial news and currency comparison sites, but almost no retail transaction happens at that exact rate. Banks, card networks, and money transfer services add a spread on top, sometimes several percentage points, and may layer a fixed fee as well; a currency conversion fee calculator exists specifically to reveal that markup, which is often larger than the advertised "no fee" transfer implies.
Frequently Asked Questions
What exactly is a pip in forex trading?
A pip is typically the fourth decimal place in most currency pair quotes (the second decimal for pairs involving the Japanese yen), representing the smallest standard price movement tracked in forex trading.
Does purchasing power parity mean exchange rates are "wrong"?
Not exactly — PPP measures relative cost of living and price levels, while market exchange rates reflect trade flows, interest rates, and capital movements, so the two can diverge substantially without either being incorrect for its purpose.
