🛠 What is the ROI Calculator?

The ROI Calculator is a quick and reliable tool that calculates the net profit and ROI percentage based on two simple inputs:

  • Initial Investment — the amount of money you put in.
  • Return Received — the amount of money you got back.

With these inputs, the calculator uses the following formula:

ROI (%) = (Net Profit / Investment) × 100
Net Profit = Return Received − Initial Investment

This helps you gauge how effective or profitable an investment has been.

✅ How to Use the ROI Calculator (Step-by-Step)

Using this tool is incredibly easy. Here's a step-by-step guide:

  1. Go to the ROI Calculator section on the webpage.
  2. Enter your Initial Investment in the first input field (e.g., $1000).
  3. Enter the Return Received in the second input field (e.g., $1500).
  4. Click the "Calculate" button.
  5. The tool will instantly display:
    • Net Profit (e.g., $500.00)
    • ROI Percentage (e.g., 50.00%)
  6. To try again with different values, click the "Reset" button to clear inputs and results.

💡 Real-World Example

Let’s say you invested $2,000 in an online advertising campaign, and it brought in $3,200 in revenue.

  1. Enter 2000 in the "Initial Investment" field.
  2. Enter 3200 in the "Return Received" field.
  3. Click "Calculate".

Result:

  • Net Profit = $1,200.00
  • ROI = 60.00%

That means for every dollar you invested, you earned $0.60 in profit.
