Key Takeaways
- Picking a marketing budget as a percentage of revenue is a rough guess dressed up as a strategy.
- A real budget starts with a revenue goal and works backward through your sales process.
- You need three numbers: average job size, close rate, and cost per lead. That’s it.
- Home services CPLs in 2026 average $144-$181; construction contractor search ads specifically average $165.67 per lead, and roofing hits $228.15.
- Healthy marketing brings in at least $3 for every $1 spent. Anything less and you’re paying yourself to grow.
- Most wasted spend has nothing to do with spending too little – it’s broken tracking, slow follow-up, and channels running on autopilot with no goal.
Introduction
Ask ten contractors how they picked their marketing budget and you’ll likely get ten different answers. A rough percentage of revenue, whatever felt right last year, whatever the agency quoted, or what was left over after payroll.
None of those are budgets, they’re just fancy guesses.
The right number isn’t a percentage, it’s a calculation. It starts with a revenue goal, works backwards through how you actually close jobs, and lands on a figure you can defend. Do it right and you stop asking, “am I spending too much?” and start asking the only question that matters, “is this spend bringing in the jobs I need?”
In this blog, Estes Media will walk you through the most effective ROI framework. No padded industry average, just the math that tells you what to spend and why.
Why “Just Spend 5-10%” Doesn’t Really Work
You’ve probably heard the rule: spend 5-10% of revenue on marketing. And while it’s not necessarily wrong, it’s just not useful.
A $2M residential remodeler and a $20M commercial contractor both land inside that range, but their marketing needs look nothing alike. Using the same percentage for both is how budgets end up either too small to matter or too fat to justify, and how contractors end up convinced marketing “doesn’t work” when really, it just never had a chance.
Construction also underspends compared to just about everyone. A recent CMO Survey found construction companies only put about 1% of their revenue into marketing, while B2B services overall sit closer to 9%.[1] That’s not a benchmark to copy, it’s a warning.
When most of your industry is running on fumes, “average” isn’t something to aim for.

The Three Numbers You Need Before Setting a Budget
Before you can set a real budget, you need three pieces of information. Without them, whatever number you land on is a guess.
- Your average job size. Not what you wish you had or what that one dream project was. What your jobs actually averaged over the last 12 months. For example, residential remodels can run $40K-$80K, commercial GC work can hit seven figures, and roof replacements can land between $8K-$20K
- Your close rate. Out of every 10 qualified leads, how many sign a contract? For most contractors this runs between 15% and 35%. Guess wrong on this one and every calculation that follows is off.
- What a lead costs. Home service CPLs in 2026 averaged $181 for B2B and $144 for B2C per WebFX’s 2026 benchmarks, with premium jobs (kitchen, bath, roofing) landing in the $350-$500 range.[1]
Diving specifically into the construction and contractor subcategory, LocaliQ’s Home Services Search Ads Benchmarks put the average Google search ad lead at $165.67 for construction and contractor work, and $228.15 for roofing, the highest CPL in all of home services.[2]
These three numbers replace “spend 5-10% and hope” with something you can actually defend in a meeting.

How to Figure Out Your Marketing Budget in Four Steps
Step 1: Set Your Revenue Goal
Start with the revenue you need marketing to bring in, not total revenue. Referrals and repeat customers are already handling some of the lifting. Marketing only has to cover the gap.
Example: You want marketing to bring in $3M in new business this year, $3M that wouldn’t have walked in the door without it.
Step 2: Figure Out How Many Jobs That Is
Divide your revenue goal by your average job size. If your average job is $50K, that’s $3M + $50K = 60 jobs. If that number already looks crazy, good news: your marketing budget isn’t the problem. Your revenue goal or your job size is, and no amount of ad spend will fix either one.
Step 3: Work Backwards to Leads
At a 25% close rate, 60 jobs mean 240 qualified leads. But not every form-fill qualifies, a lot of inquiries turn out to be tire-kickers, wrong-fit projects, or people who are just bored on a Tuesday. If 60% of inquiries turn into qualified leads, you actually need 400 total.
Now factor in your website. If it converts 2% of visitors into inquiries, you need 20,000 website visits. For context: the average contractor site converts closer to 0.5%[1], a number that’s been kicking around for years and still holds up in most audits we run. That gap between 0.5% and 2% is why website performance matters just as much as ad spend, sometimes more.
Step 4: Multiply by What Leads Cost
Using the LocaliQ construction and contractor average of $165.67: 400 leads x $165.67 = $66,000 in paid ads alone. That’s just paid ads. Add in your website, SEO, email, CRM, content, and the people actually running it all, and a $3M revenue goal usually needs a $150K-$250K in total marketing investment.
Which, surprise, lands right in that 5-10% range everyone quotes. The difference now is the number isn’t a guess anymore, it’s tied to real jobs, real leads, and real costs, and you can explain it to anyone without blinking.

How to Tell If Your Marketing Is Actually Working
Once you’ve got a budget, hold it to these numbers. If it’s not hitting them, something’s broken and it probably isn’t the budget.
- Overall marketing ROI – 3 to 1 minimum. For every $1 you spend, you should get at least $3 back. Below that and you’re potentially funding growth out of your own pocket, which is a rough way to run a business.
- Customer value acquisition cost – 3 to 1 or better. Over a customer’s lifetime, they should be worth at least three times what it cost to get them. This is the clearest tell of whether your math actually works.[1]
- Return on ad spend – 5 to 1. Construction lead costs are high, but so are the job values. The math works fine when the ads do.
- SEO return – 4 to 6x within 12 to 18 months. SEO takes longer to kick in, but once it does it keeps paying out long after the invoice is paid, making it boring in the best way.
- Email marketing return – one of the highest of any channel. Especially for contractors sitting on years of old customer lists they haven’t touched since 2019.
When your numbers are below these, don’t automatically blame the budget because nine times out of ten, the leak is somewhere else.

Where Contractors Lose Money on Marketing
Speaking of leaks, here’s where they usually are. If your marketing isn’t paying off, the problem probably isn’t that you’re spending too little. It might be one of these:
No lead tracking. If you don’t know which ad, page, or campaign a lead came from, every decision you make is a guess. This is the single most common problem we see, and it’s also the most expensive.
Slow follow-up. A lead you call back in five minutes is dramatically more likely to close than one you call back in five hours. Leads don’t wait around for you to check your voicemail.
Channels running on autopilot. Social posts, trade show booths, sponsorships, the print ad in the local chamber magazine, if they don’t have a clear purpose or a way to measure results, they quietly burn through your budget while everyone politely ignores them.
A website that doesn’t convert. Getting your site from 0.5% to 2.3% conversion usually brings in more leads than doubling your ad spend would, and costs a whole lot less.
Ghosting old leads. Most contractors spend real money generating leads, then do absolutely nothing with the 70-80% that don’t buy right away. Those leads aren’t dead, they’re just waiting for you to stop ignoring them.
Here’s how this compounds: spend $100K a year with 30% of it leaking through the cracks and you’ve donated $30K to the void, roughly the same as losing one or two signed jobs. Plug the leaks first and the budget numbers that follow usually improve.
How Estes Media Builds Construction Marketing Budgets
At Estes Media, we’re a construction marketing agency that builds budgets around real outcomes. Every engagement starts with the numbers that matter – your average job size, your close rate, what your leads are actually costing you – and the budget gets built from there to hit specific revenue goals.
What we recommend for a $2M residential contractor looks nothing like what we put together for a $30M commercial builder, because it shouldn’t. We measure success the same way you do; leads, signed jobs, and revenue. If the spend isn’t returning what it should, we restructure it with no attachment to last quarter’s plan if the numbers don’t back it up.
Conclusion: Stop Guessing, Start Calculating
Construction marketing shouldn’t be a mystery. It’s accountable math, and if you’re not holding your spend to real numbers then you’re gambling.
Every dollar should trace back to a real lead, a real job, and real revenue. When the math is doing the work, your budget stops being a stress source and starts being a growth engine. That’s the whole point of running marketing like a real part of the business.
If your current marketing budget isn’t tied to a clear ROI target, it’s time to run the numbers. Speak with a construction marketing specialist at Estes Media today, we’ll do the math with you.
