Open calculator →A connected workflow
Connect advertising return, acquisition cost, order value and customer retention. Work through the calculators in the order that matches the decision rather than collecting isolated metrics.
- Validate attribution: Define which orders and customers belong to the campaign before calculating return.
- Apply margin: Convert attributed revenue into gross contribution before comparing it with advertising and creative costs.
- Connect the customer: Review order value, repeat purchase behaviour, returns and churn for the same acquired cohort.
- Set the scale rule: Increase spend only when the downside case remains above break-even and cash payback is acceptable.
Checks before acting
- Include agency, creative, discount and fulfilment costs where relevant.
- Do not credit one conversion fully to several channels.
- Separate new-customer economics from existing-customer orders.
