How it works: pick your industry, how many enquiries you want each month, your close rate and average sale value. The calculator estimates ad spend on Google Search and Facebook/Instagram lead ads using published US benchmark data, plus the customers and revenue that spend could produce.

How to use the result
- Treat the number as a starting budget for the first 60 to 90 days, then replace benchmarks with your own cost per lead.
- If return on ad spend is below about 3x on revenue, check your margins: you may need a higher close rate, higher job value or lower cost per lead before scaling.
- Local Services Ads, strong landing pages and fast follow-up usually beat the averages.
