How ROI Calculator Works?
Calculate your return on investment, annualized ROI, and net profit from any investment.
Enter the total amount you invested.
Enter the total returns received (including the original investment).
Enter the investment duration in years.
The calculator subtracts the investment amount from total returns to find net profit.
ROI percentage is calculated as (Net Profit / Investment Amount) x 100, and annualized ROI adjusts this for the time period.
Formula Used
Net Profit = Total Returns - Investment Amount | ROI (%) = (Net Profit / Investment Amount) x 100 | Annualized ROI = ((1 + ROI)^(1/Years) - 1) x 100
ROI does not account for risk, inflation, or taxes. Always compare ROI across investments with similar risk profiles and time horizons for a meaningful assessment.
Important — Read Before You Decide
- ROI doesn't account for risk — high ROI may mean high risk
- Inflation erodes real returns — nominal ROI can be misleading
- ROI ignores the time value of money without annualization
- Different investments have different liquidity profiles
- Tax implications can significantly reduce actual ROI
- Past ROI doesn't guarantee future returns
- Opportunity cost of capital isn't captured in basic ROI
What Happens If You Ignore These?
- Chasing high ROI without risk assessment leads to losses
- Ignoring inflation overstates real investment gains
- Comparing ROI across different time periods is misleading
- Not factoring taxes leads to overestimated net returns
- Neglecting opportunity costs results in suboptimal allocation
Smart Tips
- Always compare ROI after adjusting for inflation
- Use annualized ROI to compare investments of different durations
- Factor in all costs including fees and taxes
- Diversify investments to manage risk vs return
- Set a minimum acceptable ROI before investing
