How to use it

  3. Read the results and the plain-language note under them.
  4. Change one number at a time to see what moves the result.

Formulas used

  • Profit before ads = price − all costs except ads
  • Break-even ACOS = profit before ads ÷ price × 100
  • Maximum CPC = profit before ads × conversion rate
  • Expected ACOS = CPC ÷ (conversion rate × price) × 100
  • Ad cost per order = CPC ÷ conversion rate
  • Minimum conversion rate = CPC ÷ profit before ads

Assumptions and limits

  • Conversion rate is clicks-to-orders, one unit per order.
  • Costs include marketplace fees; enter them yourself.
  • Averages hide differences between keywords, so use this as a guide for target setting.

Results are estimates from your inputs, not financial advice or a guarantee of outcome.

Frequently asked questions

Where do I get CPC and conversion rate?

From your advertising console reports for the same campaign and period.

Can I use this for Walmart or other ads?

The maths is the same. Use that marketplace’s fees and ad reports.
