CPC Formula
Total Ad Spend ÷ Total Clicks = CPC
If you spend $500 on a Facebook campaign and receive 250 clicks, your CPC is $2.00.
Why CPC Matters
CPC is the primary efficiency metric for paid social advertising. It tells you how much you're paying to drive each interested user to your website or landing page. Lower CPC means your ad creative and targeting are resonating — you're not paying a premium to reach people who click.
Typical CPC Ranges by Platform (as of 2025)
- Facebook/Instagram: $0.50–$2.00 for most B2C industries; $2–5+ for competitive verticals like finance or legal
- LinkedIn: Significantly higher at $5–$15+ due to precise B2B targeting
- X (Twitter): $0.50–$3.00 for promoted posts
- TikTok: $0.10–$1.50, lower due to the platform's native ad format blending with organic
These ranges vary significantly by audience, creative quality, bidding strategy, and industry.
CPC vs. CPM
- CPC (Cost Per Click) — You pay only when someone clicks; useful for traffic and conversion goals
- CPM (Cost Per Mille/Thousand Impressions) — You pay per 1,000 views; better for brand awareness goals
Reducing CPC

- Tighten audience targeting — highly relevant audiences click more
