What is an Annuity?

An annuity is a financial product that provides a series of payments made at equal intervals. It can be used for retirement savings, investment planning, or any scenario where you deposit money regularly and earn interest over time.

Key types of annuities include:

  • Ordinary Annuity – Payments made at the end of each period
  • Annuity Due – Payments made at the beginning of each period

This calculator focuses on ordinary annuities, which are the most common for savings and investment purposes.


How the Future Value of an Annuity is Calculated

The future value (FV) of an annuity is determined using the formula:FV=P×(1+r)n1rFV = P \times \frac{(1 + r)^n – 1}{r}FV=P×r(1+r)n−1​

Where:

  • P = Payment per period
  • r = Interest rate per period (as a decimal)
  • n = Number of periods

This formula accounts for compound interest, meaning each period’s interest is calculated on both the principal and accumulated interest.


How to Use the Annuity Calculator

Using the calculator is straightforward and requires only three inputs:

Step 1: Enter Payment per Period

This is the amount you plan to deposit or contribute regularly.
Example: $200 monthly savings

Step 2: Enter Interest Rate per Period (%)

Input the expected rate of return per period.
Example: 5% annual interest

Step 3: Enter Number of Periods

Specify the total number of contributions or periods.
Example: 12 months, 10 years (if yearly, input 10)

Step 4: Click Calculate

The tool instantly computes the future value of your annuity, showing how much your regular payments will grow over time.

Step 5: Copy or Share Results

You can easily copy results to your clipboard or share them via supported devices for convenience.


Example Calculation

Let’s assume you want to save $100 per month for 5 years at an annual interest rate of 6%, compounded monthly.

  • Payment per period: $100
  • Interest rate per period: 0.5% (6% / 12 months)
  • Number of periods: 60 (5 years × 12 months)

Using the formula:FV=100×(1+0.005)6010.005$3,465.35FV = 100 \times \frac{(1 + 0.005)^{60} – 1}{0.005} \approx \$3,465.35FV=100×0.005(1+0.005)60−1​≈$3,465.35

This shows that your total contributions grow significantly thanks to compounding interest.

Advantages of Compounding in Annuities

Compound interest allows your savings to grow faster than simple interest. For example:

Monthly PaymentInterest RatePeriodsFuture Value
$1005%60$6,680
$2005%60$13,360
$1006%60$6,950

Even small adjustments in payment or rate significantly increase the future value.
