DECISION MAP

Start with the question you actually have

The metric should follow the decision, not the other way around.

“What can this order afford?”Contribution margin, maximum CPA and target ROAS. “What can I pay for traffic?”CPC, CPM, CTR and break-even CPC. “Where is the funnel leaking?”CTR, conversion rate, RPV and AOV. “Are our leads actually becoming customers?”CPL and lead-to-customer conversion. “Do customers stay and buy again?”Retention, churn, purchase frequency and LTV:CAC. “What budget is required for the target?”Budget, target ROAS, CPA and traffic assumptions.
WHY THE LIBRARY IS BUILT THIS WAY

Every calculator should connect to another business decision

A standalone formula is easy to copy. The value comes from showing how one result changes the next. Contribution margin influences maximum CPA and break-even ROAS. Conversion rate changes affordable CPC. Retention and purchase frequency change the value of customer acquisition. Budget forecasts depend on all of those assumptions.

ROAS Lab keeps inputs visible, uses worked examples, and links related calculations so users can audit the logic instead of receiving a black-box score. Review the calculation methodology for formulas and edge cases.
