We believe you should be able to spend your money abroad without penalty, so we do not charge any foreign transaction fees! Please note that Mastercard will determine the exchange rate used, and that rate does fluctuate frequently. You can always check the current exchange rate on the Mastercard website - enter 0% when you're asked to enter the 'Bank Fee,' and select US Dollar (USD) as your 'Card Currency.'
Remember, Aspiration also rebates all ATM fees! For every ATM fee you are charged by an ATM overseas, you will be rebated $4 on the statement date of the following month.
