ROI Calculator
Return on investment percentage
How to Use the ROI Calculator
Calculate return on investment percentage, net profit, and annualized returns. Essential for evaluating investment performance and comparing opportunities.
ROI Formula
ROI = (Final Value - Initial Investment) / Initial Investment × 100
For time-based comparison, we also calculate annualized ROI using the compound annual growth rate (CAGR) formula.
Interpreting Results
- Positive ROI = profit; negative ROI = loss
- Compare annualized ROI across investments with different time periods
- Higher returns often come with higher risk
- Consider opportunity cost—what could the money have earned elsewhere?
Beyond Simple ROI
For comprehensive investment analysis, also consider factors like risk-adjusted returns, liquidity, tax implications, and diversification benefits.
Frequently Asked Questions
ROI = (Current Value - Initial Investment) / Initial Investment x 100. If you invested $10,000 and it is now worth $13,000: ($13,000 - $10,000) / $10,000 x 100 = 30% ROI. This measures total gain as a percentage of your original investment.
A good ROI depends on the investment type and risk. Stock market average is 10% annually. Real estate typically returns 8-12%. A 15%+ annual return is excellent. Riskier investments should offer higher potential returns to compensate for increased risk.
ROI is total return regardless of time. Annualized return converts total ROI to a yearly rate for comparison. A 50% ROI over 5 years equals about 8.4% annualized. Annualized returns help compare investments held for different periods.
Subtract all costs from your final value before calculating. If you invested $10,000, paid $500 in fees, and have $13,000 now: ($13,000 - $10,000 - $500) / $10,000 = 25% true ROI. Always account for fees, commissions, and taxes.
Yes, negative ROI means you lost money. If $10,000 investment is now worth $8,000: ($8,000 - $10,000) / $10,000 = -20% ROI. Negative returns happen during market downturns or poor investment choices. Long-term investing reduces negative return risk.
Convert all returns to annualized percentages for fair comparison. Also consider risk level, liquidity, and time horizon. A 6% guaranteed CD return may be preferable to a potential 10% stock return for some investors.
