Step-by-step working
  1. Net profit = $7,200.00 − $5,000.00 = $2,200.00
  2. ROI = $2,200.00 ÷ $5,000.00 × 100 = 44%
  3. Annualised = (1.44)^(12 ÷ 6) − 1 = 107.36%

How to use the ROI Calculator

  1. Enter the total cost of the investment.
  2. Enter the total amount it returned.
  3. Optionally add how many months it took, then press Calculate.

Formula

ROI = (amount returned − cost) ÷ cost × 100

Annualised ROI = (returned ÷ cost)12 ÷ months − 1

Examples

  • 5,000 in, 7,200 back: ROI = 44%. Over 6 months that is about 107% annualised.

Frequently asked questions

How is this different from ROAS?

ROAS uses revenue; ROI uses profit. Use the cost of goods and all expenses in the cost figure for a true ROI.

Is there a longer-term version?

For investments held over years with income, use the Investment Return Calculator.
