Method
Net gain = final value − initial investment − additional costs. ROI percentage = net gain ÷ total invested cost × 100.
Example
An investment of $10,000 that becomes $12,500 after $500 in costs has a $2,000 gain and 19.05% ROI on $10,500 invested.
Limits
Check inputs and units. Important academic, financial or professional decisions should be confirmed against an appropriate source.
