How we calculate CPC
CPC shows how much each click costs. When you also provide impressions, we calculate CTR and connect the two metrics.
Use the CPC CalculatorFormula
CPC = investment ÷ clicks
CTR (%) = (clicks ÷ impressions) × 100
CPC = CPM ÷ (CTR × 10)
Variables
- investment
- Total campaign budget.
- clicks
- Valid clicks recorded.
- impressions
- Optional; enables the CTR calculation.
Step-by-step calculation
- We divide the investment by the number of clicks.
- If impressions are provided, we calculate CTR and show clicks per dollar.
Worked example
Inputs
- Investment: $900
- Clicks: 1,800
- Impressions: 120,000
Calculation
CPC = 0.50
CTR = 1.5%
CPC of $0.50 with a CTR of 1.5%.
Common mistakes
- Optimizing only for CPC and losing traffic quality.
- Ignoring that better creatives raise CTR and lower CPC without touching the bid.
