What This Currency Calculator Does

A currency calculator converts an amount of money from one currency to another using an exchange rate. This tool uses live mid market rates for 36 major currencies, including the US dollar, euro, British pound, Indian rupee, Japanese yen, UAE dirham, and Saudi riyal.

Beyond a simple conversion, it shows what you receive after a bank or card fee, the cost of that fee in both currencies, the inverse rate, and how your amount looks in other popular currencies. For currencies covered by European Central Bank reference rates, a 30 day chart and a badge show whether today's rate is better or worse than the recent average.

If live rates cannot load, the calculator falls back to saved reference rates and clearly labels them as offline, so you always know how current the figures are.

Currency Conversion Formulas

Basic conversion

Converted = amount × rate Rate = units of target currency per 1 unit of source $1,000 × 0.8888 EUR/USD = €888.75

Inverse rate

Inverse = 1 ÷ rate 1 ÷ 0.8888 = 1.1252 USD per EUR

Cross rate through the US dollar

B per A = (B per USD) ÷ (A per USD) INR per EUR = 96.37 ÷ 0.8888 = 108.44

Amount after a fee

Received = amount × rate × (1 − fee) €888.75 × (1 − 3%) = €862.09; fee cost €26.66

Example rates are from 3 October 2026 and are for illustration. The calculator itself uses the latest rates available when you open the page.

How Exchange Rates Work

Exchange rates are set by supply and demand in the global foreign exchange market, where banks and institutions trade currencies around the clock on weekdays. Interest rates, inflation, trade balances, and economic news all move them.

Mid market, buy, and sell rates

  • Mid market rate: the midpoint between wholesale buy and sell prices, used by this calculator.
  • Buy and sell rates: what a bank or exchange counter offers you. The gap from the mid market rate is their markup.
  • Reference rates: official daily rates published by central banks, such as the ECB euro reference rates and the Federal Reserve H.10 release.

Fixed (pegged) currencies

Some currencies are pegged to the US dollar. The UAE dirham is held at about 3.6725 per dollar and the Saudi riyal at 3.75, so their rates against the dollar barely change while their rates against other currencies move with the dollar.

ℹ️
Rates update continuously during market hours. Weekend rates usually reflect the Friday close.

Worked Example: The Real Cost of Conversion Fees

A traveler converts $1,000 to euros at a mid market rate of 0.8888. Here is what different options deliver:

MethodFee or markupEuros receivedCost vs mid market
Mid market rate0%€888.75€0.00
Low fee transfer service1%€879.86€8.89
Card with foreign transaction fee3%€862.09€26.66
Bank exchange5%€844.31€44.44
Airport exchange counter8%€817.65€71.10

On a single $1,000 conversion the difference between the cheapest and most expensive option is more than €70. Fee levels in this table are examples; check the exact rate and fees quoted by your provider and enter them in the calculator.

💡
Compare the amount you will receive, not the advertised fee. A service with "no fee" can still give you a poor exchange rate, which is a hidden fee.

Tips to Get a Better Exchange Rate

  • Pay in local currency abroad. Decline dynamic currency conversion at card terminals and ATMs.
  • Use a card without foreign transaction fees. Many travel cards charge 0% and use network rates close to mid market.
  • Avoid airport and hotel exchanges. They often have the widest markups.
  • Compare total cost for transfers. For international money transfers, US providers must disclose the exchange rate, fees, and amount received before you pay.
  • Exchange larger amounts less often. Fixed fees per transaction add up on small conversions.
  • Watch the trend. Use the 30 day chart to avoid converting right after a sharp drop, but remember short term moves are hard to predict.

Common Currency Conversion Mistakes

  • Reading the rate backward. 0.8888 EUR per USD is not the same as 0.8888 USD per EUR. Check which currency is the base.
  • Ignoring the markup. The rate a bank shows may already include its margin even if it charges no separate fee.
  • Using an old rate. Rates move daily; check the "rates as of" date before relying on a figure.
  • Rounding too early. Keep at least four decimal places in the rate for large amounts.
  • Forgetting receiving fees. Some banks charge to receive international transfers.

For prices with tax, try the sales tax calculator, and to measure buying power over time, use the inflation calculator.

Currency Conversion for Travel, Shopping and Transfers

Travel. Before a trip, convert your daily budget into the local currency so menu and hotel prices make sense at a glance. Enter the fee your card charges abroad, often 0% or 3%, to see the true cost of each purchase. If you plan to withdraw cash, add the ATM operator fee to your estimate, since it is charged on top of any card fee.

Online shopping. When a foreign store lists prices in its own currency, your card issuer converts the charge on the day it posts, which may differ from the day you ordered. Refunds are converted again at a later rate, so a returned item can come back worth slightly more or less than you paid.

Sending money abroad. For family support, tuition, or property payments, compare providers by the amount the recipient gets. A small rate markup on a large transfer can cost more than a flat fee. Under US rules, remittance providers must give you a receipt showing the rate, fees, and the amount delivered, and you generally have 30 minutes to cancel after paying.

Business invoices. If you bill or pay suppliers in another currency, record the rate used on the invoice date and on the payment date. The difference is a currency gain or loss for your books. For recurring payments, check the trend chart before scheduling large transfers.

Frequently Asked Questions

How do you calculate a currency conversion?
Multiply the amount by the rate quoted as target currency per one unit of source currency. At 0.8888 euros per dollar, $1,000 is about €888.75. To convert back, divide by the rate or multiply by the inverse, about 1.1252.
What is the mid market exchange rate?
It is the midpoint between wholesale buy and sell prices and the fairest reference rate. Consumers rarely receive it exactly because providers add a markup or fee.
How much do currency conversion fees cost?
A 3% card fee turns $1,000 at 0.8888 into about €862.09 instead of €888.75, costing about €26.66. Airport counters and dynamic currency conversion often cost more.
How do you calculate a cross exchange rate?
Divide the target currency's rate per US dollar by the source currency's rate per dollar. With 96.37 rupees and 0.8888 euros per dollar, one euro is about 108.44 rupees.
Should I pay in local currency or my home currency abroad?
Usually the local currency. Paying in your home currency triggers dynamic currency conversion, which often uses a marked up rate. Paying locally lets your card issuer apply its own rate.
