Future Value of Annuity
$205,517 USD
Total amount accumulated at the end of the investment period.
An annuity is a series of regular payments made at fixed intervals (monthly, quarterly, or annually). The future value of an annuity is the total amount that those payments accumulate to, including earned interest. There are two types: ordinary annuities (payments at period end) and annuities due (payments at period start). This calculator handles both, letting you project growth for retirement plans, pension income, structured settlements, and systematic savings programs.
The calculator applies the annuity future value formula, which multiplies each payment by its accumulated interest using the compound interest rate and period count. You input the periodic payment amount, annual interest rate, investment duration, and payment frequency (monthly or annually), then select whether payments occur at the end (ordinary) or start (due) of each period. The formula accounts for all compounding automatically and displays the total contributions, interest earned, and final balance.
FV = PMT × [((1 + i)^n - 1) / i] × (type factor)
where i = rate per period, n = number of periods, type factor = 1 (ordinary) or (1 + i) (due)The formula calculates how much each payment grows when compounded over the full investment period. The type factor adjusts for whether payments occur at the start or end of each period, creating a slight difference in final value.
| Input | Result | Notes |
|---|---|---|
| Monthly payment: $500, 5% annual rate, 20 years, ordinary | $186,682 | Consistent monthly contributions grow to nearly $187k with modest interest compounding over two decades. |
| Annual payment: $6,000, 7% rate, 15 years, ordinary | $137,826 | Higher annual payments at 7% demonstrate faster growth; this scenario suits high-contribution retirement plans. |
| Monthly payment: $300, 3% rate, 30 years, due | $144,288 | Paying at the period start (due) slightly increases final value versus ordinary; long timeframes benefit from early contributions. |
Ordinary annuities have payments at the end of each period; due annuities have payments at the start. Due annuities earn slightly more interest because each payment has an extra period to compound. The difference is multiplied by (1 + i).
Yes. The calculator handles both monthly and annual payment frequencies. Select the frequency that matches your payment schedule, and the formula automatically adjusts the interest rate per period.
Use the 'real' interest rate (nominal rate minus inflation rate) rather than the nominal rate. This accounts for purchasing power loss and gives a more realistic picture of growth.
Annuity calculators work for both. Savings and investments use future value (what you'll have). Loan amortization is a related but distinct calculation (how much you owe over time).
The calculator assumes constant interest and consistent payments. Real returns fluctuate, and payments may change. Use this as a baseline projection, not a guarantee.
