It can calculate how much investment will be worth over a period of time, or the necessary rate, duration of time, periodic deposits or initial investment required to achieve a desired accumulation. Compoundee makes these calculations simple with a user interface that can be used by anyone, with or without previous exposure to financial calculations. It is very flexible in that it allows for different investment lifetimes, different compounding periods, periodic withdrawals or deposits, and different rates of return. Compoundee also automatically provides an inflation and tax adjusted amounts for each of the equations that it solves.
