What it measures
Google Ads Quality Score is a 1-10 rating of your keyword, ad, and landing-page relevance that directly affects your actual cost per click.
Formula
Estimated CPC = Baseline CPC × (5 ÷ Quality Score)
Worked example
A $2.50 baseline CPC at a Quality Score of 8 drops to about $1.56, roughly 37.5% cheaper than an average score of 5.
Typical benchmarks
- Average Quality Score
- 5/10
- Strong Quality Score
- 8-10
- CPC at QS 10 vs 5
- ~50% cheaper
How this calculator works
Higher Quality Scores earn lower costs. Using the common modifier of 5 ÷ Quality Score, a score of 10 roughly halves CPC versus an average score of 5, while a low score sharply raises it.
Frequently asked questions
How does Quality Score affect cost? +
Google rewards relevance: a higher Quality Score lowers your actual CPC and improves ad rank, so the same budget buys more and better-positioned clicks.

Increase expected CTR, ad relevance, and landing-page experience — the three components Google grades.
What are the three components of Quality Score? +
Expected click-through rate, ad relevance, and landing-page experience. Each is rated below average, average, or above average in the keyword's status.
Does Quality Score directly set my bid? +
No, it doesn't set your bid, but it factors into Ad Rank and the actual CPC formula, so a higher score lowers what you pay and improves position.
How fast can I improve Quality Score? +
Ad relevance and CTR can shift within days of better-matched ad copy, while landing-page experience improvements take longer to be re-evaluated.
