Compound Growth Formula

A = P(1 + r/12)^(12t) + PMT × [(1 + r/12)^(12t) – 1] / (r/12)
A = Future value
P = Principal (initial investment)
r = Annual return rate (decimal)
t = Time in years
PMT = Monthly contribution

Frequently Asked Questions

Pro Tips

1

Time in the market beats timing the market. Missing just the 10 best trading days over 20 years can cut your returns in half. Stay invested through downturns.

2

Tax-advantaged accounts (401k, Roth IRA) let your investments grow tax-free or tax-deferred — always max these before investing in taxable accounts.

3

The Rule of 72: divide 72 by your annual return to estimate years to double. At 7%, money doubles every ~10.3 years. At 10%, every 7.2 years.

4

Increase your contribution by just 1% of salary each year you get a raise. You won't notice the difference in take-home pay, but it compounds dramatically over decades.
