A budget is not a number you pick — it is a number you derive. This runs the five-line math from our budget guide on your own economics: what a job is worth, how often you close, and how many jobs you actually want.
Your three numbers
Recurring-revenue trades: run it once on first-job value (conservative), once on first-year value (the ceiling you can actually afford).
What the math says
Affordable cost per booked job
25–35% of ticket keeps one-off work profitable
$100–$140
Calls needed per job
1 ÷ close rate
3.0
Affordable cost per call
Job ceiling × close rate
$33–$46
Monthly budget for your target
25 jobs × cost per job
$2,500–$3,500
Testing phase
Enough spend to gather real conversion data in 30–60 days without betting the quarter.
A planning range, not a quote — click costs in your market decide whether the cost-per-call ceiling is realistic. Check yours against our observed ranges by trade.
What to do with the number
Sanity-check the cost-per-call ceiling against what clicks actually cost in your trade — if your market’s clicks make a call cost more than your ceiling, the fix is the landing page and keywords, not a bigger budget. And before spending it, decide the scoreboard: cost per booked job, tracked from click to invoice.
