How Much Does Google Ads Cost for Contractors?

This is the first question almost every contractor asks before starting Google Ads — and it rarely gets a straight answer. Most guides give you vague ranges that don't account for your trade, your market, or how much you're actually willing to commit.

Here's the real breakdown.

The Two Costs You're Paying

Before anything else, understand that Google Ads for contractors involves two separate costs that often get lumped together and cause confusion.

Ad spend is the money you pay directly to Google every time someone clicks your ad. This goes straight to Google — not to any agency or management service.

Management fees are what you pay someone to build and run the campaign. At Service Contractor Growth, that's $500/month. Some agencies charge a percentage of ad spend (typically 15–20%), others charge flat fees. Either way, it's separate from what Google charges.

When someone says "I'm spending $1,000/month on Google Ads," make sure you know which bucket that number falls into — or whether it's both combined.

What Does Ad Spend Actually Cost Per Click?

Cost-per-click varies significantly by trade, market size, and competition. Here are realistic ranges for common contractor trades targeting transactional, local-modifier keywords:

These are ranges for properly structured campaigns using exact and phrase match keywords. Broad match campaigns often run lower CPCs but generate far more irrelevant clicks — the cost-per-lead ends up being worse, not better.

What's a Realistic Cost Per Lead?

Cost-per-click tells you what you're paying for traffic. Cost-per-lead tells you what that traffic is actually worth. The two are connected by your conversion rate — the percentage of people who click and then actually call or submit a form.

A well-structured contractor campaign with a dedicated landing page typically converts at 8–15%. A campaign sending traffic to a generic homepage might convert at 2–4%.

At a $12 average CPC and a 10% conversion rate, your cost per lead is $120. At the same CPC with a 3% conversion rate, it's $400. The campaign structure matters more than the keyword bids.

Realistic cost-per-lead targets by trade for a properly built campaign:

• Electricians: $80–$180 per lead
• Plumbers: $60–$150 per lead (emergency keywords convert higher)
• Tree service: $50–$130 per lead
• Excavation: $70–$200 per lead (higher ticket, lower volume)
• HVAC: $100–$250 per lead

These numbers should be evaluated against your average job value and close rate. A $150 lead cost is completely acceptable if the average job is $3,000 and you close 40% of quotes.

How Much Should You Actually Budget?

The minimum starting ad spend we recommend is $1,000/month. Below that, you don't generate enough clicks to collect meaningful data, and Google's algorithm can't optimize effectively toward leads.

Here's how we think about budget tiers:

$1,000/month effective budget

$700 to Search Ads, $300 to Local Service Ads. One campaign, one primary service, 5–10 tight keywords. The goal at this tier is to dominate one service in one area before expanding. You're not trying to be everywhere — you're trying to own one thing.

$1,500–$2,000/month effective budget

More room to target two services, run A/B tests on ad copy, and let LSAs generate consistent call volume. This is where campaigns start to produce reliable, repeatable data. Enough budget to optimize toward cost-per-lead rather than just clicks.

$2,500+/month effective budget

Multiple campaigns, multiple services, location-specific ad groups. Competitor keyword targeting becomes viable. Remarketing layers can be added. At this level, the campaign becomes a real lead generation system rather than a test.

The Google Ads Credit Strategy for New Accounts

If you're starting a brand new Google Ads account, there's a promotional credit program that significantly increases your effective buying power in the first 60 days. The tiers work like this:

The practical pitch: if you commit $1,500, Google gives you $1,000 back in free credit. You're essentially getting two and a half months of ads for the price of one and a half. That's a meaningful difference — and it's the best time to start if you've been sitting on the fence.

What You're Not Accounting For (That Will Kill Your ROI)

Budget and CPC numbers only matter if the rest of the system works. The most common places contractor Google Ads campaigns bleed money have nothing to do with bids:

• Sending paid traffic to a homepage instead of a dedicated landing page
• No conversion tracking — paying for clicks with no visibility into which ones became leads
• Broad match keywords pulling in irrelevant searches
• No negative keyword list — paying for searches like "electrician school" or "DIY plumbing"
• Too many services targeted on too small a budget — spreading spend too thin

Fix those structural issues and the same budget produces significantly better results. Most of the time when a contractor says "Google Ads didn't work for me," the campaign was structurally broken from day one — not underfunded.

The Bottom Line

Expect to spend $1,000–$2,000/month in ad spend to run a competitive contractor campaign. Add $500/month for management. At the $1,500 spend tier, Google's credit program gives you $1,000 back — making the first 60 days your highest-value window to start.

The number that matters most isn't what you spend — it's your cost per lead relative to your average job value. A $150 lead that closes into a $4,000 job is a very good deal. Track that number from day one.
