Question 1

How do you calculate CPC?

Accepted Answer

CPC = Total Ad Spend / Total Clicks. If you spent $2,000 and received 1,600 clicks, your CPC is $1.25. This is your average cost per click — individual clicks may cost more or less depending on auction competition and targeting.

Question 2

What is a good CPC for ecommerce?

Accepted Answer

It depends on your margins and conversion rate. Average CPCs: Google Search $1-$5, Google Shopping $0.30-$1.50, Facebook/Instagram $0.50-$2.00, TikTok $0.50-$1.50. The real question is whether your CPC is below your break-even CPC (max affordable CPC). This calculator shows your break-even CPC based on your margins and conversion rate.

Question 3

What is break-even CPC?

Accepted Answer

Break-even CPC is the maximum you can pay per click and still make a profit. Formula: AOV × Gross Margin × Conversion Rate. With $60 AOV, 60% margin, and 2.5% CVR: $60 × 0.60 × 0.025 = $0.90 break-even CPC. Any CPC above $0.90 means you lose money on average.

Question 4

How do I lower my CPC?

Accepted Answer

Improve Quality Score/relevance (better ad copy and landing pages), refine targeting (exclude non-converting audiences), use negative keywords (Google), test different bidding strategies, improve CTR (higher CTR = lower CPC on most platforms), and test different ad placements and formats.

Question 5

What is the relationship between CPC, CPM, and CTR?

Accepted Answer

CPC = CPM / (CTR × 10). Or equivalently: CPM = CPC × CTR × 10. A $10 CPM with 2% CTR = $0.50 CPC. Improving CTR lowers your effective CPC even if CPM stays the same. This is why creative quality (which drives CTR) is the biggest lever for reducing click costs.
