How to use it
- Enter your initial investment amount.
- Enter the final value of the investment.
- Enter the number of years you held the investment.
- Click Calculate to see ROI and CAGR.
What it does – The Investment Return Calculator takes three simple inputs (initial amount, ending amount, years held) and instantly returns two key performance metrics: Return on Investment (ROI) and Compound Annual Growth Rate (CAGR).
Why it matters – ROI tells you the total percentage profit or loss over the entire holding period, giving a quick snapshot of success. CAGR smooths out the ups and downs, showing the steady‑rate equivalent you would need each year to reach the ending value.
How to read the numbers – A positive ROI means you earned money; a negative ROI means a loss. CAGR is expressed as an annual percentage; the higher it is, the faster your money grew on average. Use both figures together to compare investments of different lengths or cash‑flow patterns.
Pro tips
- Round to two decimals for easy comparison.
- Use the same currency for both amounts.
- If years is less than 1, convert to a fraction of a year.
- Check that initial investment isn’t zero to avoid errors.
Real-life examples
