Simply enter the parameters needed to calculate the future value (FV) from the present value (PV) investment. No personal information is saved within these pages - closing the webpage or refreshing will clear inputs.

The future value compound interest formula is as follows:

A = P * ( 1 + ^r/_n )^nt

A = Final amount
P = initial principal amount
r = interest rate (in decimal)
n = compounding intervals within a time period
t = number of time periods elapsed

This formula allows the user to quickly arrive at the final accrued amount, but through simple programmatic iterations, this mini-application can also break down the steps of every compounding interval, then display on a line graph.

It should be noted that with contributions, the app assumes an equal distribution within the year ( ^{yearly contribution} / ₁₂ ), and are added to the growing equity prior to the interval compounding.

(Example: if monthly contributions are $100, and the compounding intervals are quarterly, $300 will be added to the present value before the interval interest rate is applied.)
