Google Ads Waste Calculator
Estimate how much of your Google Ads budget is being wasted — and what you could recover with smarter campaign management.
What causes Google Ads waste?
Most wasted Google Ads spend falls into five categories that are easy to miss without systematic review:
- Broad match keywords without negatives — triggering irrelevant searches that burn budget on zero-intent clicks
- Poor CTR from ad-to-keyword mismatch — low Quality Scores driving up CPC across the account
- Landing page conversion failure — traffic arriving but not converting, inflating effective CPA
- Uncapped automated bidding — Target CPA or ROAS strategies overspending during low-quality traffic windows
- Impression share lost to budget — spending too broadly on too many campaigns instead of dominating the best-performing ones
