Annuity Calculator
Calculate future value, present value and required payment for recurring cash flows.
Use this annuity calculator to model recurring payments with more confidence. It helps you estimate how much a steady contribution plan can grow, what a fixed payment stream is worth today and how much you need to invest each period to reach a target amount.
The tool works with rate per period and number of periods, so you can model monthly, quarterly or yearly scenarios as long as both use the same time base. You can also switch between end-of-period payments and beginning-of-period payments.
The result highlights the main value, total contributions, the difference created by growth or discounting and the annuity factor used in the formula. That makes it useful for savings plans, pension estimates, cash-flow planning and side-by-side comparisons of recurring financial decisions.
Use clear inputs to get a more useful result.
How to use Annuity Calculator

Frequently asked questions
What should I prepare before using the tool?
Keep the key values, labels and units ready before filling in the fields. Cleaner inputs make the final result easier to review and compare.
Can I test different scenarios on the same page?
Yes. The safest approach is to change one field at a time, compare the outputs and note which value actually changes the final answer.
Is the result ready to use without checking it?
It is better to treat it as support. Review the output once more before using it in a quote, document, spreadsheet, technical task or published page.
