Ad Budget Calculator for Local Service Businesses

Local service ads aren't about scale — they're about owning a 15-mile radius before your competitor does. With maybe 200-500 commercial-intent searches per month in your category, the entire game is capturing that finite demand without overpaying for it.

Local service businesses operate on math the DTC and SaaS playbooks don't understand. A plumber's job is worth $200-$2,000. A roofer's is $8,000-$25,000. A personal injury lawyer's signed case is worth $15,000-$80,000. Your CPL ceiling is wildly different from the agency next door, and your budget should reflect job value, not industry averages.

The channel hierarchy in 2025 is settled: Google Local Services Ads (LSA) first, Google Search second, Microsoft Ads third, Meta last. LSA charges per lead ($15-$80 for trades, $50-$200 for legal/medical), shows above paid search, and gives you the Google Guaranteed badge. If you're not running LSA in eligible verticals, you're handing leads to whoever is.

Google Search CPCs for local service queries in 2025:

• Plumbing/HVAC emergencies: $25-$80 CPC
• Personal injury law: $80-$400 CPC
• Dental implants/cosmetic: $15-$50 CPC
• General contractors/roofing: $10-$40 CPC
• Local agencies/B2B services: $5-$20 CPC

The single biggest mistake local businesses make: running broad match keywords with no negative list. A plumber bidding on plumbing without negatives pays for plumbing courses, plumbing supply, DIY plumbing fix, and tire-kickers in cities they don't serve. Build a 200+ word negative keyword list before launching. Add cheap, free, DIY, course, jobs, salary, school, plus every city outside your service radius.

KPIs that matter, in order: cost per booked appointment (not cost per lead), show rate (how many booked actually show up), and revenue per appointment. CPL is a vanity metric if half your leads are price-shoppers in the wrong zip code. Track calls over 60 seconds as the conversion event, not form fills — local intent is voice-driven.

Geo-targeting is where most budgets bleed. Set radius targeting to your actual service area minus 2 miles, then layer location bid adjustments: +30% on your highest-LTV neighborhoods, -50% on the edges. Exclude your office address (employees searching the brand name will tank your data). On Google Ads, switch from Presence or interest to Presence only — otherwise you'll pay for clicks from people researching your city from across the country.

Attribution windows are short for emergencies (a clogged drain converts in 20 minutes) and long for considered services (30-90 days for cosmetic dentistry, legal consults, kitchen remodels). Match your conversion window to the buying cycle. A 7-day default window will undercount your remodeling leads by 40%+.

Meta has a narrow but real role: retargeting website visitors within your service radius and running before/after photo carousels for visual services (landscaping, dentistry, med spa). Cold Meta prospecting for emergency services is a money pit — nobody scrolling Instagram books an emergency plumber. CPCs of $1.50-$4 look cheap until you see a 2-5% lead-to-job rate vs. 25-40% from LSA.

Minimum viable budget is $1,500-$2,500/month for one channel done well. Below that, you'll spread across channels, learn nothing, and conclude paid ads don't work. They do — you just didn't give any single channel enough data to optimize.

Example

A two-location dental practice spending $4,000/month allocates $1,800 to Google Search (implants, Invisalign, emergency dentist), $1,200 to LSA, $600 to Microsoft Ads, and $400 to Meta retargeting. Result: 35-50 new patient consults at $80-$110 cost per consult, with implant cases worth $3,500-$6,000 driving the ROAS.
