Use this calculator to estimate the total cost of a foreign transaction made with your Visa card. This tool calculates the final billing amount by factoring in the exchange rate and your bank's specific foreign transaction fees.

Note: Visa exchange rates fluctuate daily. The rate applied is usually the rate on the date the transaction is processed, not necessarily the date of purchase.
Understanding Visa Exchange Rates & Fees
When you use your Visa card internationally, the final amount you see on your statement is rarely just a direct conversion of the price you saw in the store. Several factors influence the final cost:
1. The Visa Network Rate
Visa sets a daily exchange rate for currencies worldwide. This rate is generally very close to the mid-market rate (the wholesale rate banks use to trade with each other). However, it is not live; it is usually fixed once per day.
2. Foreign Transaction Fees (FX Fee)
This is the most significant extra cost. While Visa may charge a small assessment fee (often around 1%), the card-issuing bank (e.g., Chase, Wells Fargo, HSBC) often adds a markup. A common standard is 3%. This means for every $100 you spend, the bank adds $3 to the bill.
3. Dynamic Currency Conversion (DCC)
Sometimes, a merchant's payment terminal will ask if you want to pay in the local currency or your home currency. Always choose the local currency. If you choose your home currency, the merchant sets the exchange rate (DCC), which is almost always significantly worse than the Visa rate.
How the Calculation Works
The formula used in this calculator is:
Base Amount: Transaction Amount × Exchange Rate
Bank Fee: Base Amount × (Fee Percentage / 100)
Total Billed: Base Amount + Bank Fee
Example Calculation
Imagine you are from the US and buy a dinner in Paris for 100 Euros.
Exchange Rate: 1 EUR = 1.08 USD
Bank Fee: 3%
Base Conversion: 100 × 1.08 = $108.00
Fee Calculation: $108.00 × 0.03 = $3.24
Total Cost: $108.00 + $3.24 = $111.24
In this scenario, your effective exchange rate became 1.1124 USD per Euro due to the added fees.

// Get input values
var amountInput = document.getElementById('transactionAmount').value;

var feeInput = document.getElementById('bankFee').value;
// Clean and parse inputs
var amount = parseFloat(amountInput);
var rate = parseFloat(rateInput);

// Validation
if (isNaN(amount) || amount <= 0) {
alert("Please enter a valid positive transaction amount.");

alert("Please enter a valid positive exchange rate.");
return;
}
if (isNaN(feePercent) || feePercent < 0) {
alert("Please enter a valid bank fee percentage (0 or higher).");
return;
}
// Calculation Logic
var baseConverted = amount * rate;
var feeAmount = baseConverted * (feePercent / 100);
var totalBilled = baseConverted + feeAmount;
var effectiveRate = totalBilled / amount;
// Display Results
document.getElementById('baseResult').innerHTML = baseConverted.toFixed(2);
document.getElementById('feeResult').innerHTML = feeAmount.toFixed(2);
document.getElementById('totalResult').innerHTML = totalBilled.toFixed(2);
document.getElementById('effectiveRateResult').innerHTML = effectiveRate.toFixed(4);
// Show results container
document.getElementById('results').style.display = 'block';
