📣 CPC & CPM Calculator
Calculate cost per click (CPC), cost per thousand impressions (CPM), and total ad campaign costs.
Key Ad Metrics
| Metric | Formula | Good Range |
|---|---|---|
| CPC | Spend / Clicks | $0.10–$3 (display), $1–$5 (search) |
| CPM | Spend / Impressions × 1000 | $1–$10 (display) |
| CTR | Clicks / Impressions | 0.5–2% (display) |
CPC vs CPM: When to Use Each Pricing Model
CPC (Cost Per Click) = Ad Spend ÷ Clicks. CPM (Cost Per Mille) = Ad Spend ÷ Impressions × 1,000. CPC campaigns charge only when someone clicks — ideal for direct response goals where each click has measurable value. CPM campaigns charge per thousand impressions regardless of clicks — ideal for brand awareness where exposure itself has value. Google Search defaults to CPC; display and social platforms commonly offer both.
Converting Between CPC and CPM
CPM = CPC × CTR × 10. If your CPC is $2.00 and CTR is 2%, CPM = $2.00 × 0.02 × 1,000 = $40. Conversely, CPC = CPM ÷ (CTR × 1,000). This conversion lets you compare campaigns across platforms using different pricing models.

Depends on your goal. CPC is better for direct response campaigns where each click has measurable value — you only pay for engagement. CPM is better for brand awareness campaigns where reach matters more than clicks. High-intent keywords on Google Search warrant CPC; broad awareness campaigns on YouTube or display work better on CPM.
Audience quality (demographic targeting narrows supply and raises CPM), placement (premium placements command 2–5x standard CPM), ad format (video CPMs exceed display), time of year (Q4 e-commerce season dramatically raises CPMs across all platforms), and competition in your audience segment.
CPC is determined by auction competition — the more advertisers bidding on a keyword, the higher the CPC. Keywords with high commercial intent command premium prices: 'best personal injury lawyer' ($150+ CPC) vs 'legal advice' ($8 CPC). Industry, intent, and conversion value all drive keyword-level CPC.
