Transparent mathematical formulas behind this calculation engine.
Net Profit ($)
Net Profit = Final Return - Initial InvestmentThe actual dollar earnings generated by the investment.
Return on Investment (ROI %)
ROI (%) = (Net Profit ÷ Initial Investment) × 100Percentage return relative to the original capital committed.
Investment Multiple

Worked Example
Marketing Campaign ROI ($5k Investment / $8.5k Return)
A company invests $5,000.00 into a growth initiative, generating $8,500.00 in attributed return.
- Initial Investment
- $5,000.00
- Total Return
- $8,500.00
- Net Profit
- $3,500.00
- ROI Percentage
- 70.00%
- Return Multiple
- 1.70x
- Net Profit = $8,500.00 - $5,000.00 = $3,500.00
- ROI (%) = ($3,500.00 ÷ $5,000.00) × 100 = 70.00%
- Multiple = $8,500.00 ÷ $5,000.00 = 1.70x
Takeaway: The investment yielded a 70.00% net return, turning every $1.00 of capital into $1.70.
Methodology & Assumptions

Frequently Asked Questions
Practical answers regarding margins, markups, and pricing strategy.
How is ROI calculated?
ROI is calculated by subtracting initial investment from final return to find net profit, dividing that profit by the initial investment, and multiplying by 100: ROI (%) = ((Return - Investment) ÷ Investment) × 100.
What is a good ROI for a business?
Standard long-term benchmarks range from 10%–15% annually. For short-term marketing initiatives, campaigns often target 30%–70%+ depending on product gross margin.
How is ROI different from ROAS?
ROAS measures top-line revenue divided by ad spend. ROI measures net profit after subtracting investment costs.
