Did You Know?
How Does ROI Work?
The Formula
ROI = (Gain - Cost) / Cost × 100. Gain includes capital appreciation plus any cash flows (dividends, rent). Cost is your initial investment.
Annualized ROI
Annualized ROI = ((1 + ROI/100)^(1/years) - 1) × 100. Converts total return to an equivalent annual rate for comparing investments of different durations.
Payback Period
Payback Period = Cost / Annual Gain. Measures how many years until you recover your initial investment from annual returns.

Frequently Asked Questions
What is ROI?
Return on Investment measures the percentage gain or loss relative to cost. ROI = (Gain - Cost) / Cost × 100. A 50% ROI means $1.50 back for every $1 invested. It's the most universal investment metric.
What is a good ROI?
S&P 500 historical average: ~10% annually. Real estate: 8-12%. Private equity: 15-25%. Venture capital: 25%+ (high risk). Context matters - compare risk-adjusted returns, not just raw ROI.
How do I annualize ROI?
Annualized ROI = ((1 + ROI)^(1/years) - 1). A 100% total return over 5 years = 14.9% annualized. This allows apples-to-apples comparison of investments held for different durations.
What are the limitations of ROI?
ROI ignores time value of money, risk, and cash flow timing. A 50% ROI over 1 year is much better than 50% over 10 years. Use IRR or NPV for time-sensitive comparisons.
How does ROI differ from IRR?
ROI measures total return as a percentage. IRR accounts for the timing of cash flows. A project with uneven cash flows may have 50% ROI but only 12% IRR. IRR is more accurate for complex investments.
Should I use simple or compound ROI?
Simple ROI works for single-period investments. For multi-year investments, use annualized (compound) ROI. S&P 500's ~10% average is compound. Simple ROI overstates multi-year performance.
