Decision Context
Page-specific guidance for using this result in a real planning decision.

This page estimates return on investment so you can compare projects, campaigns, purchases, or initiatives with a common performance ratio.

Use it when you need a fast way to prioritize options competing for the same budget or management attention.

ROI is useful for ranking ideas, but decisions should still consider risk, time horizon, and cash-flow timing because two projects with similar ROI can behave very differently.

Return on Investment (ROI)

ROI measures the profitability of an investment as a percentage of the initial cost. Annualized ROI accounts for the time period to enable fair comparisons.
ROI = (Final Value - Initial Investment) ÷ Initial Investment × 100% Annualized ROI = [(Final ÷ Initial)^(1/Years) - 1] × 100%

Variables:

Final ValueCurrent or ending value of the investment
Initial InvestmentOriginal amount invested
Net ProfitFinal Value - Initial Investment
YearsInvestment time period

Example

Stock Investment Example

Inputs:

Initial Investment:$10,000
Final Value:$15,000
Time Period:1 year

Steps:

  1. 1.Net Profit = $15,000 - $10,000 = $5,000
  2. 2.ROI = ($5,000 ÷ $10,000) × 100 = 50%
  3. 3.Annualized ROI = [($15,000 ÷ $10,000)^(1/1) - 1] × 100 = 50%
  4. 4.Return Multiple = $15,000 ÷ $10,000 = 1.5×
Result:
50% return on investment in 1 year

Frequently Asked Questions

What's a good ROI?

Does ROI include dividends or distributions?

Yes, ROI should include all returns from the investment - capital gains, dividends, interest, rental income, etc. Use final value inclusive of all distributions.
