Basic
What it is & how to use it
Cost per click (CPC) is what you pay on average for each click in a paid campaign. It is a unit-cost metric, not a profit metric.
How to use the CPC Calculator
1) Enter total ad spend.
2) Enter the number of clicks.
3) Read average CPC as results update.
4) Use an example chip to explore, then replace with platform exports.
Intermediate
Formula & worked example
CPC = Ad Spend ÷ Clicks.
Worked example: $500 ÷ 250 clicks = $2.00 CPC.
Both spend and clicks should be positive for a meaningful average.
Advanced
Interpretation, edge cases & next steps
Lower CPC is not always better if click quality or conversion rate drops.
Advanced: compare CPC across keywords, audiences and devices; gate scale on CPA or ROAS. Cross-check with CTR and budget planning tools.

Frequently asked questions
Can CPC be zero?
Only in odd edge cases (zero spend with clicks). Typically both inputs are positive.
Should I optimize only for CPC?
No — pair CPC with conversion rate, CPA or ROAS.
Does this include taxes or fees?
Only if you included them in the spend figure you entered.
Platform CPC vs this calculator?
Use the same date range and filters as your ads UI for a fair check.
How do I share a scenario?
Use the shareable URL when available so teammates open the same numbers.
