What Is the ROI Calculator?
The ROI Calculator measures how well an investment performed. Enter what you put in, what it's worth now and how long you held it to see your total return on investment, net profit and the annualized return (CAGR). All math runs locally.
How It Works
Enter the initial investment, the final value and the holding period in years. The ROI, net profit and annualized (CAGR) return update instantly.
When to Use It
Use it to compare investments, evaluate a project's payoff, or convert a total return into a comparable per-year rate.
Frequently Asked Questions
- What's the difference between ROI and CAGR?
- ROI is the total percentage gain over the whole period. CAGR (compound annual growth rate) expresses that as a smoothed per-year rate, which makes investments of different lengths comparable.
- Can ROI be negative?
- Yes. If the final value is less than the initial investment, the ROI and profit are negative — shown in red.
