Compound Growth Calculator
Here are a few key points to consider before using the calculator.
- Investment Doubling Timeframe: The Rule of 72 is an easy way to determine how frequently a balance will double. Years to Double = 72 ÷ Annual Growth Rate.
- Early Contributions are KEY: The earlier you contribute, the better, even without future investment.
- Investing Consistently Over Time: Investing over time is the most commonly used investment strategy and it truly pays off. Even when you contribute small amounts, compound interest makes up the difference.

Compound Growth Formula (Initial Investment with Annual Contributions)
A = P (1 + r)t + PMT x[((1 + r)t– 1) ÷ r]
- A = future value or total amount of money at the conclusion
- P = principal or initial contribution
- r = interest rate/growth rate (e.g., 5% = .05 or 10.5% = 0.105)
- t = time or the number of years the investment is left
- PMT = annual contribution (fixed amount deposited yearly)
