Free economic ceiling calculator

Stop guessing what a click can afford.

Use your own numbers. CEILR does not pull Amazon data for this calculator and does not estimate sales. It simply shows the economics your inputs support.

Pre-ad contribution = selling price − landed cost − Amazon/per-order fees − other per-order costs.

Profit-Safe CPC = (pre-ad contribution − protected contribution per order) × conversion rate.

Cash-supported CPC = available ad cash ÷ (planned daily clicks × planning days).

Fundable CPC = the lower of Profit-Safe CPC and cash-supported CPC. If required cash inputs are missing, CEILR leaves Fundable CPC uncalculated.

This lightweight marketing calculator is intentionally narrower than CEILR's in-app Profit Profile and cash/inventory context.
