Calculate marketing ROI
This tool uses contribution profit (revenue × margin) so you can compare channels without fooling yourself with top-line revenue.
Tip
If you don’t know your margin, start with a conservative guess. ROI swings hard when margin is wrong.
Result
Assumptions
- Revenue is attributed fairly (same attribution window across channels).
- Margin is gross margin (not revenue). Include variable costs.
How to use this calculator
Keep the attribution window consistent (same time range, same conversion definition). Otherwise you will compare numbers that do not mean the same thing.
If you’re evaluating partnerships or affiliates, include the variable costs you will pay (commissions, payout fees, chargebacks) inside your margin.
Where this helps
• Decide whether a campaign is profitable (or just looks good on revenue).
• Compare channels: ads vs content vs affiliates (using the same margin model).
• Find break-even revenue needed before you scale spend.
