#marketing#calculators#roi

Marketing is only effective if it drives more revenue than it costs. But calculating the exact return on investment (ROI) or return on ad spend (ROAS) can be tedious.

Instead of opening a spreadsheet, just use the calculator below.

Return on Investment (ROI) helps you see the actual profit percentage after all costs are paid. It is the ultimate metric for business health.

How to Use the ROI Calculator

To get an accurate reading of your marketing effectiveness, follow these steps:

  1. Gather your data: Total your ad spend, agency fees, and any other direct costs for the campaign.
  2. Track your revenue: Use your attribution software or e-commerce dashboard to find the gross revenue linked to those costs.
  3. Input your values: Enter them into the "Investment" and "Revenue" fields above.
  4. Review results: The ROI and ROAS will update instantly without needing to refresh the page.

The Math Behind ROI and ROAS

Providing transparency in your marketing math is crucial for trust. Here are the exact formulas our tool uses:

  • ROI Formula: ((Total Revenue - Total Investment) / Total Investment) * 100
  • ROAS Formula: Total Revenue / Total Investment

Real-World Strategic Example

Imagine you are running a Google Ads campaign for a boutique coffee brand.

You spend $2,500 on ads and management fees in a month. Those ads result in $10,000 in gross revenue.

  • Your ROAS is 4.0x, meaning for every dollar you put in, you got four dollars back.
  • Your ROI is 300%, showing that your net profit (before other COGS) is triple your initial marketing spend.

Frequently Asked Questions

What is a "good" ROAS in 2026? Most e-commerce businesses aim for a minimum of 3x to 4x ROAS to remain profitable after accounting for fulfillment and product costs. High-margin businesses like SaaS can often sustain a lower ROAS because of high customer lifetime value (LTV).

Should I include labor costs in "Total Investment"? For a true ROI calculation, yes. You should include ad spend, creative costs, and any agency or freelancer fees. However, for "ROAS", most marketers only include the direct media spend (the actual dollars paid to Google/Meta).

How is ROI different from Profit Margin? While both measure profitability, ROI compares your profit to your investment, whereas profit margin compares your profit to your revenue. ROI tells you how hard your money is working for you.
