How to read CPC

CPC is the amount paid for one ad click. It is useful only when read with conversion rate, order value, and margin, because cheap clicks can still lose money if they do not convert.

Usage notes

  • CPC = ad spend / clicks
  • Projected clicks from target CPC = ad spend / target CPC
  • Estimated conversions = clicks x conversion rate
  • CPA = ad spend / estimated conversions
  • ROAS = estimated revenue / ad spend x 100
  • Break-even CPC = average order value x gross margin x conversion rate

Frequently asked questions

Is a lower CPC always better?expand_more

No. A low CPC can still be unprofitable if conversion rate, order value, or margin is weak.

What conversion rate should I use?expand_more

Start conservatively around 1-2% if you do not have data, then replace it with real campaign or analytics data.

What is break-even CPC?expand_more

It is a reference for the highest CPC that can still leave gross profit per click before other costs.
