Annuity Calculator
Calculates present and future values of an annuity given payment, rate, and term.

What Annuity Calculator does
An annuity calculator that determines both the present and future value of a series of periodic payments. Users input a regular payment amount, an interest rate per period, and the total duration of the investment. The tool then projects what those consistent payments would accumulate to by a specified end date, assisting with retirement income planning or investment strategy evaluation. | The Pi Day Calculators version offers a straightforward interface for entering payment, rate, and term parameters. It explicitly calculates both present and future values, allowing users to see the current worth of future payments alongside the projected accumulation. While other annuity calculators exist, this implementation focuses on the core financial values associated with periodic payments over time, providing a clear view of how regular savings can grow.
