Formula / Working

The ROI is calculated using the basic formula: ROI(%)=Net ProfitInvestment Cost×100ROI (\%) = \frac{\text{Net Profit}}{\text{Investment Cost}} \times 100ROI(%)=Investment CostNet Profit​×100

Where:

• Net Profit = Total returns from investment – Initial investment
• Investment Cost = The amount initially invested

Some calculators also allow adjustments for time period, providing annualized ROI: Annualized ROI=(Ending ValueBeginning Value)1n−1\text{Annualized ROI} = \left( \frac{\text{Ending Value}}{\text{Beginning Value}} \right)^{\frac{1}{n}} – 1Annualized ROI=(Beginning ValueEnding Value​)n1​−1

Where nnn = number of years
