Result interpretation
Annuity FV accumulates equal payments to the last period. Due payments compound for one extra period. This is a textbook equal-payment model.

Formula
Annuity FV is payment times the accumulation factor; payments at period start gain one more period of growth.
Formula and assumptions
PMT is the periodic payment, i the annual rate divided by payment frequency, and n the count. Rate, payment schedule, and compounding frequency are fixed; use Compound Interest when an initial principal also matters.
WORKED EXAMPLE
Example
- Set payment 100, annual rate 10%, three annual payments.
- End-of-period FV is 100×1.1² + 100×1.1 + 100 = 331.
- Beginning-of-period FV is 331×1.1 = 364.10; total contributions are 300 in both cases.
Frequently asked questions
How is this different from the compound interest calculator?
This is the standard equal-payment formula. Compound Interest also models an initial principal and monthly contributions with yearly growth.
Is there a gain at zero interest?
No. Future value equals total payments.
Does this predict investment returns?
No. A fixed rate is an assumption; market variation, taxes, fees, and missed payments change outcomes.
