Average Return on Investment Calculator
Investors seek to understand how well their investments perform over time. The Average Return on Investment (ROI) is a vital metric that shows the average yearly percentage gain or loss on an investment. It helps investors compare different investment opportunities, measure growth, and make informed financial decisions.
The Average Return on Investment Calculator simplifies this calculation by providing an easy way to determine your investment’s average annual return over multiple years, taking compounding into account.
Formula
The formula to calculate Average Annual ROI is:
Average Annual ROI (%) = ((Total Gain ÷ Initial Investment) ^ (1 ÷ Number of Years) − 1) × 100
This formula calculates the compound annual growth rate (CAGR), reflecting the average yearly return.
How to Use the Average Return on Investment Calculator
- Enter Total Gain from Investment — The final value of your investment after gains.
- Enter Initial Investment Amount — The amount you originally invested.
- Enter Number of Years — The total time period of the investment.
- Click “Calculate” — The calculator will show the average annual ROI as a percentage.
This helps investors understand how their money grew on average each year.
Example Calculation
Suppose you invested $10,000 and after 5 years the investment is worth $16,105.
Average Annual ROI = ((16,105 ÷ 10,000) ^ (1 ÷ 5) − 1) × 100 ≈ (1.6105 ^ 0.2 − 1) × 100 ≈ (1.1 − 1) × 100 = 10%
Your investment grew on average by 10% annually.
Why Average ROI is Important
Knowing the average ROI helps you:
- Evaluate investment performance
- Compare different investment options
