ROI Calculator Measure Your Return on Investment.

ROI Formula

To calculate ROI, subtract the initial investment from the final value to determine the net return. Divide the net return by the initial investment and multiply by 100.

Net Return = Final Value − Initial Investment

ROI Calculation Example

Suppose your business invests $10,000 in a project. The investment generates a final value of $13,500, including the original investment.

The net return is $3,500 ($13,500 − $10,000). Dividing $3,500 by the original $10,000 investment and multiplying by 100 gives an ROI of 35%.

How to Interpret Your ROI

A higher ROI can indicate a better return relative to the amount invested, but it should not be evaluated in isolation.

ROI vs ROAS: What's the Difference?

ROI and Return on Ad Spend (ROAS) are both performance metrics, but they measure different things.

For example, an advertising campaign may generate strong revenue compared with ad spend but still deliver a low or negative ROI after product costs and other expenses. Use the metric that matches the question you need to answer.
