How it works

An ordinary annuity pays at the end of each period; an annuity due pays at the start. Future value = PMT × [(1+r)^n − 1] / r, where r is the periodic rate and n is the number of periods. Present value discounts those cash flows back to today. Use this for structured settlements, lottery payouts, and savings plans.
