Formula
Ordinary annuity: FV = PMT × [((1 + r)^n − 1) / r]
Annuity due: FVdue = FV × (1 + r)
How to calculate
- Enter the regular payment amount.
- Use the interest rate for each payment period.
- Enter the total number of periods.

Frequently asked questions
What is an annuity?
An annuity is a stream of equal payments made at regular intervals.
What is the difference between ordinary annuity and annuity due?
An ordinary annuity assumes payments are made at the end of each period. An annuity due assumes payments happen at the beginning of each period.
Can I use this calculator for monthly savings?
Yes. It is commonly used for monthly or annual savings plans.
Why does payment timing matter?
Payments made earlier have more time to earn returns, so annuity due results are slightly higher.
