About this calculator
The future value of a lump sum uses the standard compound interest formula, FV = PV × (1 + r)^n, where a one-time investment (PV) grows at a fixed annual rate (r) compounded over a number of years (n) — the same formula behind virtually every long-term investment growth projection.
Because compounding means each year’s growth is calculated on an ever-larger balance, the gap between simple and compound growth widens dramatically over longer time horizons. This calculator takes your initial investment, annual rate, and number of years to show what that lump sum becomes at the end of the period.
