About this calculator
This calculator combines two effects: compound interest growing the starting principal, and a future value of annuity calculation for a stream of regular monthly deposits added on top — the full formula is FV = P(1+r)ⁿ + PMT × [((1+r)ⁿ − 1)/r]. This is different from a plain compound-interest calculator, which only handles a single lump sum.
It's used by people saving toward retirement, a house down payment, or an emergency fund who plan to contribute a fixed amount every month, letting them see how much of the final balance comes from their own deposits versus investment growth.
