Future Value Formulas
Lump Sum
FV = PV × (1 + r/n)^(n×t)
PV = Present Value, r = rate, n = compounds/year, t = years
Ordinary Annuity
FV = PMT × [((1+r)^n - 1) / r]
PMT = Payment amount, r = rate per period, n = periods

Frequently Asked Questions
What is future value?
Future value (FV) is the value of a current asset or sum of money at a specified date in the future, based on an assumed growth rate. It answers: "How much will my money be worth in X years?" This is the cornerstone of financial planning and investing.
What is the difference between future value and present value?
Future value calculates what today's money will be worth in the future (compounding forward), while present value calculates what future money is worth today (discounting backward). They are inverse calculations using the same time value of money principles.
How does compounding frequency affect future value?
More frequent compounding produces higher future values. Money compounded daily grows faster than money compounded annually at the same rate. The difference becomes more significant with higher rates and longer time periods. Daily compounding at 5% yields an effective rate of 5.13%.
What is an ordinary annuity vs annuity due?
An ordinary annuity has payments at the end of each period (like most loans). An annuity due has payments at the beginning of each period (like rent). Annuity due has a higher future value because each payment has one extra period to earn interest.
How do I calculate future value manually?
For a lump sum: FV = PV × (1 + r)^n. For an annuity: FV = PMT × [((1 + r)^n - 1) / r]. Where PV = present value, r = interest rate per period, n = number of periods, PMT = payment amount. Combine both for deposits with regular additions.
Why is future value important for retirement planning?
Future value shows how much your savings will grow by retirement, accounting for compound interest and regular contributions. It helps determine if you're saving enough, compare different investment strategies, and set realistic retirement goals based on your current savings rate.
