What Is This Calculator?
Return on Investment (ROI) measures the profitability of an investment relative to its cost. It is expressed as a percentage and helps you compare the efficiency of different investments. A positive ROI means the investment gained more than it cost; a negative ROI means the opposite.
How to Calculate
To calculate ROI: 1) Determine the total cost of your investment. 2) Determine the total gain (or current value) from the investment. 3) Subtract the cost from the gain. 4) Divide the result by the cost. 5) Multiply by 100 to get a percentage. Formula: ROI = (Gain − Cost) / Cost × 100.
Examples
Example: You invest $10,000 in a marketing campaign that generates $15,000 in revenue. ROI = ($15,000 − $10,000) / $10,000 × 100 = 50%. This means for every dollar invested, you earned $0.50 in profit.
Recommended Tools
For advanced ROI tracking across multiple campaigns and channels, consider analytics platforms like Tableau or Microsoft Power BI that can aggregate data from multiple sources and provide real-time ROI dashboards.
