How to use

An annuity turns a lump sum into equal periodic payments, common for pensions, loans and structured settlements.

Formula

PMT = PV · r / (1 − (1 + r)−n)

FAQ

Is this for loans or payouts?

Both — the math is identical, only the direction of cash differs.

What if the rate is zero?

Payment is simply PV divided by the number of periods.
