What it measures
Google Ads keyword cost is the estimated monthly spend to bid on a keyword, projected from its search volume, expected click-through rate, and CPC.
Formula
Clicks = Search volume × CTR · Cost = Clicks × CPC
Worked example
A keyword with 20,000 monthly searches at a 5% CTR drives 1,000 clicks, costing about $2,500 at a $2.50 CPC.
Typical benchmarks
- Avg. Search CTR
- 3-6%
- Top-position CTR
- 10%+
- Realistic capture
- Fraction of volume
How this calculator works
Clicks = search volume × CTR. Cost = clicks × CPC. You won't capture all searches — your share depends on ad rank, budget, and match type — so treat this as an upper-bound estimate.
Frequently asked questions
How do I estimate keyword cost? +
Multiply monthly search volume by your expected CTR to get clicks, then by CPC to get cost. Use Keyword Planner for volume and CPC inputs.
Will I get all the searches? +
No. Budget, match type, and competition limit your impression share, so actual clicks are usually a fraction of total volume.
Where do I find keyword search volume and CPC? +
Google's Keyword Planner provides average monthly searches and top-of-page bid estimates, which you can feed into this calculator.
Will I really get all those clicks? +
No. Budget, match type, ad rank, and competition cap your impression share, so actual clicks are typically a fraction of total search volume.
How does match type affect keyword cost? +
Broad match reaches the most queries (and can cost more on irrelevant traffic), while phrase and exact match limit reach to tighter, usually higher-intent searches.
