Real-Life Examples

Example 1: Annual Retirement Contributions

You contribute $6,000/year to a retirement fund earning 8% for 30 years.

Given

PMT = 6,000k = 0.08n = 30

Step-by-Step

1.FVA = $6,000 × [(1.08)^30 - 1] / 0.08
2.FVA = $6,000 × [10.0627 - 1] / 0.08
3.FVA = $6,000 × 113.2832
4.FVA = $679,699.40
Result:679,699.40

Your annual contributions will grow to $679,699.40 over 30 years.

Example 2: Vacation Fund

Save $2,000/year at 5% annual return for 10 years.

Given

PMT = 2,000k = 0.05n = 10

Step-by-Step

1.FVA = $2,000 × [(1.05)^10 - 1] / 0.05
2.FVA = $2,000 × 12.5779
3.FVA = $25,155.79
Result:25,155.79

Your vacation fund will total $25,155.79 after 10 years.

Frequently Asked Questions

An ordinary annuity is a series of equal payments made at the end of each period. Most loans, bond coupon payments, and retirement contributions are structured as ordinary annuities.

The future value of an annuity is the total amount accumulated after making a series of equal periodic payments, including all interest earned. It tells you how much your regular savings will grow to.

In an ordinary annuity, payments are made at the end of each period. In an annuity due, payments are made at the beginning. An annuity due is always worth more because each payment has one extra period to earn interest.

The basic annual formula works for annual payments. For monthly savings, use the m-times-per-year version of the formula, which adjusts the rate and number of periods for the compounding frequency.
