Compound interest is interest earned on both your original money and the interest it has already earned. Because each interest payment starts earning interest of its own, a balance grows along a curve rather than a straight line. This calculator projects the future value of a starting balance plus optional regular contributions, using the formula A = P(1 + r/n)^(nt) for the lump sum and the future-value-of-a-series formula for the ongoing deposits, compounded as often as you choose.
For example, 1,000 invested for 10 years at 7% a year, with 100 added every month, grows to about 19,300. Of that, roughly 13,000 is money you actually paid in (the 1,000 start plus 120 monthly deposits) and about 6,300 is interest the account earned for you — money that came from nothing but time and compounding.
Use the solve-for tabs to run the projection backwards: instead of the end balance, pin a target and solve for the starting amount, the return rate, the monthly contribution or the number of years you need. That makes it a planning tool for a house deposit, a college fund or any long-term savings goal.

Maitiro ekuzviisa muzvinyorwa zvinokosha sei?
The more often interest compounds, the more you earn, because each new interest payment starts earning interest sooner. The effect is small but real over long periods.

Ndeipi kusiyana kuri pakati pekudzoka kwemari nemari?
A big one. Because growth compounds, a couple of extra percentage points of return can nearly double the final balance over 20 or 30 years. Try changing only the rate to see how sensitive long-term investing is to it.
