THE THINKING BEHIND THE NUMBER

How to use this calculator

Enter the economics of one acquired order, excluding advertising. The remaining contribution is the highest first-order CPA before profit falls to zero.

THE METHOD

Break-even CPA = selling price − discount − all non-ad variable costs.

A practical example

For illustration, enter selling price / aov ₹1,000, cogs ₹300, shipping ₹70, packaging ₹20. With the remaining fields at their starting values, the break-even cpa is ₹585.00. Replace these sample figures with your own numbers before making a decision.

How to read your result

This is a first-order ceiling. Repeat-purchase value is excluded unless you model it separately.

Use the result alongside your store analytics, product costs and operating context. If the inputs are estimates, treat the output as an estimate too. Change one input at a time to understand what drives the result.

GO DEEPER

Understand the result before you act

How much can you afford to pay for a customer?

Subtract every non-ad variable cost from first-order net revenue. The remainder is your first-order CPA ceiling. If retention is strong, a business may deliberately spend more, but that requires a separate evidence-backed lifetime-value model.
