How Much Should You Budget for Google Ads? Benchmarks by Trade

"How much should I spend on Google Ads?" is the most common question we get, and the honest answer frustrates people at first: it depends entirely on what a customer is worth to you. A roofing company and a house cleaner can run the exact same campaign structure and have wildly different correct budgets, because one job is worth twenty times the other. So instead of giving you a magic number, let's build the simple math that produces your number, then ground it with realistic benchmarks by trade.

Why a Flat Dollar Figure Is the Wrong Question

If someone tells you "spend a thousand a month on Google Ads" without knowing your trade, your market, and your job value, ignore them. Budget is an output, not an input. The right way to think about it is to start from what a customer is worth and work backward to what you can afford to spend acquiring one. A business with high-ticket jobs and good margins can profitably outspend a low-ticket competitor many times over and should.

The Three Numbers That Set Your Budget

Everything flows from three figures you probably already know or can estimate.

Cost per lead. How much you pay in ad spend to generate one phone call or form fill. This varies by trade and competitiveness, and we'll benchmark it below.

Close rate. Of the leads you get, what percentage become paying customers. A good operator with fast follow-up closes a far higher share than a slow one, which is why operations and ads are inseparable.

Average job value (and lifetime value). What a customer is worth, not just on the first job but over the relationship, including repeat work and referrals. This is the number most owners underestimate, and underestimating it makes them under-invest in ads.

Multiply close rate by job value and you get what a lead is worth. Compare that to your cost per lead and you instantly know whether to spend more or pull back.

Rough Cost-Per-Lead Benchmarks by Trade

These are general ranges, not promises. Your market's competitiveness, your Quality Score, and your landing page move them a lot. Treat them as a starting sanity check.

Cleaning and maid services: generally the lowest cost per lead among the trades, often in the low-to-mid two figures, because keywords are cheaper and competition is lighter. Jobs are smaller too, so the math still has to pencil out on volume and repeat business.

HVAC and plumbing: mid-range cost per lead, pushing higher during peak season when everyone bids up "no AC" and "burst pipe" emergencies. Jobs are valuable, especially installs, so a higher cost per lead is easily justified.

Roofing and remodeling: among the highest cost per lead in home services, sometimes well into the high two or low three figures per lead, because the jobs are large and competitors bid aggressively. The saving grace is that one closed job can be worth thousands, so the tolerance for expensive leads is high.

Med spa and aesthetics: mid-to-high cost per lead with strong lifetime value, since a happy client returns for repeat treatments. Budget should reflect the recurring nature, not just the first appointment.

Dental: moderate-to-high cost per lead, justified by very high patient lifetime value. A new patient is worth far more than a single visit suggests, which is why dental practices can comfortably bid into competitive territory.

A Simple Way to Pick Your Starting Number

Don't try to nail the perfect budget on day one. Instead, start with enough spend to generate meaningful data and survive the learning period. A campaign that gets only a handful of clicks a week can never optimize, because Google's system and your own analysis both need volume to find the patterns. As a rule of thumb, fund enough daily budget to produce at least a steady trickle of leads every week, then judge it on cost per acquired customer, not on the spend itself.

Once you have a month of real numbers, the decision becomes obvious. If a customer costs you less to acquire than they're worth, scale up. You're literally buying dollars for dimes, and the only reason to stop is when you run out of demand or capacity. If acquisition costs more than a customer is worth, fix something before adding budget: tighten targeting, improve the landing page, speed up your follow-up, or sharpen your offer.

The Lever Owners Forget: Operations

Here's what the budget conversation usually misses. Your close rate and speed-to-lead change your affordable budget more than any bidding tactic. If you double the percentage of leads you turn into customers, you've effectively halved your cost per customer without touching the ad account. The business that answers every call in seconds and follows up relentlessly can profitably outbid a competitor with a fatter ad budget but a leaky funnel. Ads and operations are the same conversation.

Bottom Line

Stop asking what you should spend and start asking what a customer is worth and what you're willing to pay to get one. Build the campaign, fund it enough to learn, measure cost per acquired customer against customer value, and let that ratio tell you whether to scale or fix. The right budget reveals itself in the numbers within a month or two.
