What Is ROI?

Return on Investment (ROI) measures investment efficiency — how much profit you generate relative to cost. It’s the most universally used performance metric in finance, business, and personal investing.

Formula: ROI = ((Final Value − Initial Cost) ÷ Initial Cost) × 100. Annualized ROI normalizes returns across different time periods using compound annual growth rate (CAGR): (Final/Initial)^(1/Years) − 1.

S&P 500 Benchmark

~10% annual return historically (7% real). Always measure your ROI against this baseline — it’s your true opportunity cost.

Total vs Annualized

50% total over 5 years = 8.45% annualized. Always use annualized (CAGR) when comparing investments of different durations.

Real Estate

Typical 8–12% annually combining rental yield and appreciation. Leverage amplifies both gains and losses significantly.

ROI vs IRR

ROI is simple but ignores cash flow timing. For multi-year cash flows with irregular payments, use Internal Rate of Return (IRR) instead.

What’s Considered a Good ROI?

US stocks average 10% annually. High-yield savings: 4–5%. Real estate: 8–12%. Venture capital targets 20%+ but carries extreme risk. A “good” ROI depends entirely on the risk level and your next-best alternative — always calculate risk-adjusted returns.

Common ROI Mistakes

Comparing total ROI without adjusting for time. Ignoring fees, taxes, and inflation. Forgetting opportunity cost. Not accounting for investment risk. A 20% return over 10 years (1.84% CAGR) loses badly to a 7% annual return compounded over the same period.
