ROI Calculator Formula
ROI (%) = [(Net Profit) ÷ (Cost of Investment)] × 100
ROI (%) = [(Final Value – Initial Cost) ÷ Initial Cost] × 100
Step 1: Identify Key Values
- Initial Cost (Investment): The total money spent
- Final Value (Return): The total amount earned from that investment
Subtract the initial cost from the final value to find your net profit. Then divide by the initial cost and multiply by 100 to get the ROI percentage. This method gives a clear view of cost vs return, making it one of the most used profit margin formulas in finance.
Example of ROI Calculation
- Initial Cost = $5,000
- Final Value = $6,200
Net Profit = 6,200 – 5,000 = $1,200
ROI (%) = (1,200 ÷ 5,000) × 100 = 24%
So, your Return on Investment is 24%, This means the project earned 24% profit compared to the money you invested.
Example: Comparing Two Investments
- Cost = $10,000
- Return = $12,000
- ROI = (2,000 ÷ 10,000) × 100 = 20%
- Cost = $15,000
- Return = $18,750
- ROI = (3,750 ÷ 15,000) × 100 = 25%
Even though Investment B required more money, it produced a higher return rate.
