Frequently Asked Questions

What is an annuity?

An annuity is a series of equal payments made at regular intervals. The future value shows the total accumulated amount including all deposits and earned interest.

Beginning vs end of period?

This calculator assumes end-of-period deposits (ordinary annuity). The deposit for each period is made at the end, so it earns interest from the next period onward.
