Budget and break-even planning
Google Ads Budget Calculator for Local Business Owners
This free Google Ads budget calculator uses your average collected job, gross margin, close rate, retained profit, and lead goal to estimate a monthly and daily planning ceiling. It gives you a break-even lead-cost guardrail immediately; it does not predict Google pricing or promise profitability.
Interactive tool
Use your own numbers.
Start with what your business can afford per qualified lead. Then use the lead goal to see the monthly and daily planning ceiling—not a promise about what Google will spend or deliver.
Maximum cost per qualified lead
$90
A ceiling from your numbers—not a bid recommendation or predicted Google price.
Monthly planning ceiling
$1,800
Maximum lead-acquisition spend for the qualified-lead goal entered.
Daily planning ceiling
$59
Monthly ceiling divided by 30.4 days; use it as a financial guardrail, not a launch promise.
Assumption: Gross margin must include labor, materials, and direct job costs. It should not be confused with revenue or gross ad-platform metrics.
Use this when
- You are considering paid search for the first time.
- You are getting calls but cannot tell whether the account can be profitable.
- You need a financial guardrail before setting a monthly spend target.
What this cannot tell you
The tool helps frame an owner decision. It does not replace an audit of the live market, your competitors, your service area, or what your team can actually handle.
