How to Use This Calculator

Enter your Initial Outlay / Cost Price (e.g. 10000 in ) and Final Value / Revenue Received (e.g. 15000 in ). Results update instantly as you type — adjust any value to compare scenarios.

The Formula

Net Profit = Final Value - Initial Cost

ROI (%) = (Net Profit ÷ Initial Cost) × 100%

Investment Multiple (x) = Final Value ÷ Initial Cost

Worked Example

10,000 initial outlay yielding 15,000 in final returned value.

• Net Profit Dollars: 15,000 - 10,000 = 5,000.

00.

• Return on Investment (ROI): (5,000 ÷ 10,000) × 100 = 50.00%.

• Investment Multiple: 15,000 ÷ 10,000 = 1.50x.

Understanding Your Result

ROI = (Net Profit ÷ Investment Cost) ×

• A positive ROI means the investment returned more than it cost; negative ROI means a loss. For capital investment comparisons, use ROI alongside payback period and IRR — a high ROI over 10 years may be less attractive than a moderate ROI over 3 years.

Internal projects typically require minimum 15–25% ROI to clear a standard hurdle rate.
