ROI Calculator
Calculate return on investment (ROI) from invested and returned amounts. See net profit, payback multiple, optional annualized ROI, and simple charts.
Calculate return on investment (ROI)
ROI is a simple way to compare opportunities: how much did you get back relative to what you put in? Use it for marketing experiments, equipment purchases, hiring decisions, or investment outcomes.
Calculator
Enter your invested amount and returned amount to calculate ROI, profit, and payback multiple.
Used for annualized ROI and the growth chart.
Results
ROI is a simple metric—use it alongside risk, time, and cash flow.
How it works
- Enter your invested amount and returned amount.
- The calculator computes net profit, ROI%, and payback multiple.
- Add a duration to compute an annualized return (CAGR-style) and show a simple growth line.
Benefits
- Compare options with a single consistent metric.
- See both percent return (ROI) and absolute profit.
- Use annualized ROI to compare investments with different durations.
- Pair with cash flow tools to understand timing and payback speed.
ROI formula and examples
ROI is computed as:
ROI% = ((returned − invested) / invested) × 100
Example: invest $10,000 and return $15,000 → net profit $5,000 and ROI 50%.
ROI vs annualized return
A 50% ROI in 3 months is not the same as 50% over 3 years. Annualized ROI (CAGR-style) helps compare returns across different holding periods by converting them into an equivalent average yearly growth rate.
Use annualized ROI for longer horizons; use plain ROI for quick one-off comparisons (especially when you don’t have a duration).
Limitations of ROI
- Ignores timing of cash flows (payback speed matters).
- Doesn’t include risk or volatility.
- Can look good on paper while harming cash flow in the short term.
