What is a return on investment calculator used for?
A return on investment calculator turns raw investment data — what you paid, what it is worth, how long you held it — into meaningful performance metrics. It tells you not just how much you gained, but how fast your money grew on an annualized basis, so you can compare it fairly against any other investment or benchmark.
