Google Guaranteed lead math

LSA ROI Calculator

This version focuses only on Google Local Service Ads. No SEO. No website investment. Just Local Service Ads spend, cost per lead, close rate, job value, and what the return could look like.

Pick a trade and adjust the numbers

Start with a contractor trade. The cost-per-lead field updates to a realistic benchmark range, then you can adjust everything to fit the client’s market.

Monthly LSA ad spend

$2,000

This is the monthly amount the contractor is comfortable putting into Google Local Service Ads.

Average cost per lead

$55

HVAC often lands in the roughly $45–$70 range, though competition and market size can push it higher or lower.

Lead-to-job close rate

35%

Booked-jobs math matters more than lead count alone. Strong phone handling and quick response improve this number.

Average job value

$1,800

Use average ticket for the kind of repair, service, or install they want to bring in from LSA.

Quick benchmark notes: published 2026 sources show HVAC LSA leads around $35–$90, plumbing around $25–$75, electrical around $30–$80, and cleaning around $20–$50, depending on market and competition. [web:67] Searchlight Digital also reports an average home services LSA cost per lead of about $53 using contractor spend data, and PipelineOn cites a 43.9% book rate for contractors with LSA leads averaging $53.

What the numbers say

This is the direct Local Service Ads math contractors care about: how many leads, how many booked jobs, how much revenue, and what the return could look like.

Estimated leads

Monthly LSA leads based on budget divided by average cost per lead.

Booked jobs

12.7

Estimated jobs won based on close rate and lead quality.

Projected revenue

$22,909

Booked jobs multiplied by average job value.

Estimated ROAS

11.5x

Revenue divided by monthly LSA ad spend.

At this pace, a $2,000 monthly LSA budget at about $55 per lead could generate around 36 leads, 12.7 booked jobs, and about $22,909 in projected job revenue.

Return strength Strong

This is a directional estimate. The closer the lead quality, response speed, and sales process are to reality, the better this forecast becomes.

Book a strategy call

Directional estimate only. Local Service Ads performance depends on trade, city, competition, reviews, response rate, booking speed, hours, and disputed lead quality. Google LSA is pay-per-lead, not pay-per-click. [web:60]
