What is ROI?

Return on Investment (ROI) measures the gain or loss generated on an investment relative to the amount invested. It’s one of the most widely used metrics to evaluate investment efficiency.

ROI = [(Final Value – Total Cost) / Total Cost] × 100

Annualized ROI = [(Final / Initial)^(1/years) – 1] × 100

A positive ROI means you made money; a negative ROI means you lost money on the investment.

ROI vs Annualized ROI

Simple ROI: Shows total return regardless of time. Good for comparing investments over the same period.

Annualized ROI: Shows average yearly return, making it easier to compare investments held for different lengths of time.

What’s a Good ROI?

  • Stock Market: The S&P 500 has averaged ~10% annually over the long term. Beating this consistently is considered excellent.
  • Real Estate: Average annual returns of 8-12% including appreciation and rental income.
  • Bonds: Government bonds typically yield 3-5%; corporate bonds 5-8%.
  • Business Investment: A “good” ROI varies by industry, but 15-30% is often considered strong.
  • After Inflation: Your “real” return is ROI minus inflation (~3%). A 10% ROI = ~7% real return.

Using ROI Effectively

  • Include all costs: Factor in fees, taxes, commissions, and opportunity costs for accurate ROI.
  • Compare similar timeframes: Use annualized ROI when comparing investments held for different periods.
  • Consider risk: Two investments with the same ROI may have very different risk profiles.
  • Look at after-tax returns: Your actual return depends on how gains are taxed.
  • Don’t chase past performance: Historical ROI doesn’t guarantee future results.

Limitations of ROI

  • Ignores time value: Simple ROI doesn’t account for how long money was invested.
  • Doesn’t show risk: A 20% ROI from bonds vs crypto have very different risk levels.
  • Cash flow timing: Doesn’t capture when money was added or withdrawn.
  • Excludes dividends/income: Make sure to include all returns, not just price appreciation.
  • Can be manipulated: Different starting points or cost calculations can change ROI significantly.
