Future Value of an Annuity Calculator

What Is an Annuity?

Annuity refers to a series of equal payments made at regular intervals such as monthly, quarterly, or yearly. Examples include:

Monthly contributions to savings
Retirement fund deposits
Regular investments into a mutual fund
Scheduled deposit plans

These payments grow over time depending on the interest rate and the future value is how much they will be worth at a specific point in the future.

What Is Future Value of an Annuity?

The future value of an annuity is the total value of a series of regular payments at a given point in the future, including interest or investment gains.

Simply put:

Future Value = How much your regular deposits grow over time

This is important because:

It helps you plan long-term goals
It estimates how much your savings will grow
It helps you evaluate investment strategies

By calculating the future value, you know exactly how much your systematic savings will accumulate over time.

How the Future Value of an Annuity Calculator Works

Under the hood, the calculator uses a financial formula:

FV = A × [((1 + r)^n − 1) ÷ r]

Where:
FV = Future value of the annuity
A = Payment amount per period
r = Interest rate per period
n = Number of periods

While this looks complex, the calculator does the math for you instantly!

Step-by-Step: How to Use the Calculator

Using the Future Value of an Annuity Calculator is simple.

Here’s exactly what to do:

Enter the Periodic Payment (A)

This is the amount you contribute each period.

Example:
If you save $200 per month → enter 200

Enter the Interest Rate (r)

This is the expected annual interest rate (e.g., return on investment).
If it’s annual and you are making monthly deposits, the calculator usually auto-adjusts internally to a monthly rate based on your input.

Example:
Enter 5 for 5% interest

Enter the Number of Payments (n)

This is how many times you make the payment.

Example:
If you save monthly for 10 years → enter 120 months
(10 years × 12 months)

The tool instantly shows:

Future Value (FV) the total value your annuity grows to
Optionally breakdowns like total contributions vs interest earned

Real-World Example: Future Value of Savings

Let’s say you plan to save:

$200 per month
At an annual interest rate of 5%
For 10 years

Using the formula behind the tool, the future value might be around $31,000+ depending on compounding frequency.

This total includes:
Your total contributions
The interest earnings over 10 years

That’s the power of regular investing + compounding growth!

FAQs

What’s the difference between present value and future value?

Present Value (PV) tells you what future money is worth today.
Future Value (FV) tells you what current money will be worth in the future after earning interest.

This calculator focuses only on future value.

What happens if I increase the interest rate?

Higher interest → higher future value
Because interest compounds over time, even small rate increases make big differences over many periods.

Can this calculator work for yearly payments?

Yes just enter the payment amount and number of years instead of months.

Example:
$1,000 per year for 15 years

Does this calculator include inflation?

No unless you choose to use a real (inflation-adjusted) interest rate. The tool gives you nominal future value based on the rate you input.

Why is compound interest important?

Compound interest lets your money earn interest on interest meaning your savings grow faster as time goes on!
