How to Use the Currency Exchange Split Calculator
Exchange all your cash before the trip and you risk locking in a bad rate if it drops later. Rely entirely on local ATMs and you'll pay a withdrawal fee every single time. This calculator splits your budget between upfront cash exchange and local ATM withdrawals based on your trip length, budget, and how much exchange rate risk you're comfortable with.
Choose "Cautious" and 60% of your budget gets exchanged upfront so you're not overly dependent on cards or ATMs abroad. Choose "Prefer local ATM withdrawals" and only 25% gets exchanged upfront, letting the rest track the local exchange rate as you go. "Balanced" splits it roughly 40/60 to trade off risk and convenience.
ATM withdrawals carry a fixed fee per transaction, so withdrawing small amounts too often adds up fast. This calculator defaults to withdrawing about 3.5 days' worth of spending money at a time and estimates both the number of withdrawals and the fees (roughly $3 per withdrawal plus 1% of the amount). Upfront exchange is assumed to cost about 1.5% in spread, so you can compare the total cost of both approaches. Actual rates and fees vary by bank and card issuer, so treat these numbers as an illustrative example.
Frequently Asked Questions
It depends. Exchanging upfront costs a spread of about 1.5% but gives you cash ready to use, while local ATM withdrawals charge a fee each time but adapt better to exchange rate swings. This calculator recommends a mix of both.
Yes. Each withdrawal carries a fixed fee, so withdrawing small amounts often adds up. Pulling out about 3-4 days' worth of spending money at once balances fee savings with not carrying too much cash.
