Investment Return Calculator
Understanding how investments grow over time helps you plan for retirement, major purchases, and financial independence.
Key Terms
- Principal — The initial amount invested.
- Return Rate — The annual percentage gain on your investment.
- Compound Growth — Earnings on both principal and accumulated returns.
- Future Value — The total amount after growth over the investment period.
- Dollar-Cost Averaging — Investing fixed amounts regularly regardless of market conditions.
Investment Growth Formula
FV = PV(1 + r)^n
Where:
- FV = Future value
- PV = Present value (initial investment)
- r = Annual return rate
- n = Number of years
The Rule of 72
A quick way to estimate how long it takes your investment to double:
Years to Double = 72 ÷ Annual Return Rate
Example: At 8% return, your money doubles in approximately 9 years.

- Diversify across asset classes to reduce risk
