How savings are calculated
The calculator uses the future value formula for a growing annuity: FV = PV(1+r)ⁿ + PMT[(1+r)ⁿ − 1] / r where r is the monthly rate, n is months, PV is initial amount, and PMT is monthly contribution. To find the monthly contribution or the number of months needed, the formula is solved algebraically.
