Formula
CPC = Total Ad Spend ÷ Total Clicks
CTR = (Clicks ÷ Impressions) × 100%
CPA = Ad Spend ÷ Conversions
ROAS = Revenue ÷ Ad Spend
Max CPC = Target CPA × Conversion Rate
Example
Example: $500 ad spend, 1,000 clicks, 50,000 impressions. CPC = $500 ÷ 1,000 = $0.50. CTR = 1,000 ÷ 50,000 = 2%. With 50 conversions, CPA = $500 ÷ 50 = $10.00.
Frequently Asked Questions
- Cost Per Click (CPC) is the amount you pay each time someone clicks on your advertisement. CPC = Total Ad Spend ÷ Total Clicks. It is the standard metric for paid search and display advertising.
- A "good" CPC depends on your industry and margins. E-commerce averages $0.50–$2.00. Legal and finance keywords can exceed $50/click. The key metric is whether your CPC generates a positive ROAS (revenue ÷ ad spend > 1).
- CPC (cost per click) charges per click received. CPM (cost per mille) charges per 1,000 impressions regardless of clicks. CPC is better when you want direct response; CPM is better for brand awareness campaigns.
- Max CPC = Target CPA × Conversion Rate. For example, if your target CPA is $20 and your conversion rate is 5%, your max CPC = $20 × 0.05 = $1.00.
- ROAS (Return on Ad Spend) = Revenue from Ads ÷ Total Ad Spend. A ROAS of 3x means you earn $3 for every $1 spent. Lowering your CPC while maintaining conversion volume improves ROAS.
