Why Break-Even CPA Matters

Your Break-Even CPA (Cost Per Acquisition) is the absolute ceiling for your ad spend. If you pay more than this amount to acquire a customer, you are losing money on the first order.

By knowing your numbers, you can bid more aggressively on high-converting keywords while staying profitable. This calculator helps you factor in all variable costs—including COGS, shipping, and payment fees—to give you a realistic target.
