How It Works

Understanding the logic and mathematics behind the precision.

Core Algorithm

ROI = ((Revenue - Cost) / Cost) × 100

ROI (Return on Investment) measures the total profitability of the campaign including all overhead. ROAS (Return on Ad Spend) focuses specifically on the relationship between direct ad spend and revenue.

Scaling a campaign often leads to 'diminishing returns', where the cost of acquiring the next customer becomes slightly higher as you reach broader audiences.

Frequently Asked Questions

Usually, fixed salaries are excluded from campaign ROI to focus on the marginal profitability of the marketing effort itself.

This calculator uses Gross Revenue to derive ROAS, but you should use Revenue minus COGS (Cost of Goods Sold) if you want a true bottom-line ROI.
