Use this free future value of annuity calculator to estimate what regular monthly, quarterly, or annual payments could be worth with compound growth over time.
Calculate the future value of your payments.

To calculate the future value of an ordinary annuity, multiply the regular payment by the compound growth factor for the number of payments. The calculator below does this after converting your annual rate and payment frequency into a per-period rate.
FV = P x [((1 + r)n - 1) / r]
Example: $1,200 paid once per year for 10 years at 6% grows to about $15,816.95. Monthly payments use the same formula, but with a monthly rate and more total periods. This is an ordinary annuity calculation, where payments happen at the end of each period.
Search Console variants such as annuity future value calculator and calculate value of annuity are handled here by estimating the future value of repeated payments.
An Annuity Calculator is a tool used to determine the future value (FV) of an annuity. An annuity isn't necessarily a complex insurance product; in financial terms, it's simply a series of fixed, equal payments made over a set period. This calculator shows you how much those regular contributions will grow, thanks to the power of compound interest.
This tool calculates the future value of an ordinary annuity, where payments are made at the end of each period (like a typical 401(k) contribution from your paycheck). It helps you visualize your savings growth and plan for long-term financial goals.
To find out how much your savings will be worth, our calculator uses the standard formula for the future value of an ordinary annuity:
FV = P × [ ((1 + r)n - 1) / r ]
Let's say you want to save money by making annual payments for 10 years.
Calculation:
P = $1,200
r = 6% / 1 = 0.06
n = 10 years × 1 = 10 total payments
FV = 1,200 × [ ((1 + 0.06)10 - 1) / 0.06 ]
FV = 1,200 × [ (1.790847 - 1) / 0.06 ]
FV = 1,200 × [ 0.790847 / 0.06 ]
FV = 1,200 × 13.18079
FV = $15,816.95
In this case, you would have contributed a total of $12,000 ($1,200 x 10). The remaining $3,816.95 is the total interest you earned from compounding.
This tool is more flexible than its name might suggest. You can use this annuity payment calculator for many financial planning scenarios:
This calculator is designed for an ordinary annuity, which is the most common structure. However, it's helpful to know the difference:
An annuity is a series of equal payments made at regular intervals. A lump sum is a single one-time payment. This calculator shows how a series of annuity payments can grow into a future value.
An ordinary annuity has payments at the end of each period. This calculator uses ordinary annuity timing, which is common for many savings and retirement contribution examples.
An annuity due has payments at the beginning of each period. Because each payment earns interest for one extra period, an annuity due has a higher future value than an ordinary annuity with the same payment, rate, and time.
Your annuity's future value depends on the payment amount, interest rate, payment frequency, and number of years. For example, $1,200 paid yearly for 10 years at 6% grows to about $15,816.95 before tax.
Future value shows what regular payments may be worth later. Present value works the opposite way: it estimates what a stream of future payments is worth today.
Divide the annual interest rate by 12 to get the monthly rate, multiply years by 12 to get total monthly payments, then use FV = P x [((1 + r)n - 1) / r]. The calculator handles these conversions when you choose Monthly.
Understanding how your regular savings grow is the key to effective financial planning. After using the annuity calculator, try our Compound Interest Calculator to see how a single lump sum can grow, or our Retirement Calculator for a more detailed look at your nest egg.
