Currency conversion fee calculator

A small fee on every conversion looks like rounding. Paid on every deposit for years, it also removes what that money would have earned.

Each monthly amount loses the fee on the way in, so less is invested from the start and less compounds. If you convert back at the end, the fee is charged once more on the whole balance. Both paths earn the same return, so the gap you see is the fee and its lost growth.

The fee is whatever you enter: check your broker’s own fee schedule for the rate that applies to you. Ongoing fund charges add to this; see the fee drag calculator.
