Future Value Result
FV Breakdown — Contributions vs. Interest
Formula
FV = PMT × [(1+r)ⁿ − 1] / r = $81,939.67
PMT = $500.00 | r = 0.500000% / period | n = 120 periods | Ordinary Annuity
Period-by-Period Growth
See the balance grow each period — payment contributed, interest earned, and running total.
Note: Results assume a fixed periodic rate and equal payments throughout. Annuity due calculations assume each payment is made at the very beginning of each period. For financial planning, tax treatment, and insurance products, consult a qualified financial advisor.
An annuity calculator helps you determine the future value or present value of a series of equal, periodic payments — or find exactly how much you need to save each period to hit a target. Whether you're planning retirement contributions, evaluating a pension stream, or pricing a loan, this free annuity calculator handles ordinary annuities and annuity due with any payment frequency and interest rate.
An ordinary annuity makes payments at the end of each period (most loans and bonds work this way). An annuity due makes payments at the beginning of each period. Because annuity-due payments sit in the account one extra period, they earn slightly more interest, producing a higher future value for the same payment amount and rate.
The formula is FV = PMT × [(1 + r)^n − 1] / r, where PMT is the payment per period, r is the periodic interest rate (annual rate ÷ periods per year), and n is the total number of periods. For an annuity due, multiply the result by (1 + r) to account for the extra compounding period on each payment.
Present value tells you what a stream of future payments is worth in today's dollars, discounted at your chosen interest rate. It answers questions like 'how much is a 20-year pension of $2,000/month worth right now?' — useful for comparing lump-sum buyouts against structured payment offers.
Yes. Switch the calculator to 'Required Payment' mode and enter your target future value. The tool solves the annuity formula in reverse to tell you exactly how much to save each period — whether monthly, quarterly, or annually — to accumulate that amount at your chosen rate.
