What to prepare

  • Define the event, conversion, customer and attribution period before collecting data.
  • Use spend and outcomes from the same reporting window.
  • Distinguish revenue, contribution profit, recurring revenue and customer lifetime assumptions.

How to interpret the result

A marketing metric depends on its attribution and cost definitions. A favourable ratio is not proof that advertising caused every sale or that future customers will behave the same way.

Compare campaigns with the same attribution window and outcome definition. Test a lower conversion rate or shorter retention period before extrapolating a promising result.

Common mistakes to avoid

  • Do not double-count a customer or conversion reported by multiple channels.
  • Revenue is not the same as profit available to fund acquisition.
  • Small samples and changing cohorts can produce unstable comparisons.

Assumptions and sources

Each opportunity must appear in one stage only. Use historic probabilities and consider deal timing and correlated outcomes separately.

If your case falls outside this scope, use a more suitable calculator or contact us about an unclear method.
