Every contractor asks the same question: “How much should I spend on marketing?”. It sounds like a smart question to ask, but it is actually the wrong one. Because there is no universal answer, any marketing agency that throws a random percentage at you without looking at your actual numbers is simply guessing.
If you want to build a profitable, growth-focused business, you need to abandon the percentage game and start looking at your specific math.
The Trap of Industry Averages
You have probably been advised to spend a certain percentage of your revenue—maybe 3%, 5%, or 10%—on marketing. The problem with relying on these industry averages is that they only show what the middle of the pack is doing, and you do not want to be stuck in the middle.
Following the average can cost you market share. For example, a roofing company making $4 million a year and spending 2% puts $80,000 into marketing, while a competitor spending 8% invests $320,000. Over time, the competitor dominates search results, builds brand authority, and closes jobs effortlessly, while the 2% company wonders why leads are drying up. This gap gets harder to close with every month that goes by.
The Private Equity Threat
The home services market is also getting much more expensive because private equity (PE) firms are rapidly moving into the space. These PE-backed operators bring deep pockets and optimized systems, and they aren’t spending a mere 3% on marketing. Many are aggressively spending 15% or more to buy up market share on Google Ads and Local Service Ads.
The cost to compete is rising. If you are budgeting based on outdated figures from three years ago, you are losing ground daily to operators who view marketing as an aggressive investment rather than just an expense.
“I’ll Spend Whatever It Takes” is a Wish, Not a Plan
Many well-meaning contractors say, “I’ll spend whatever it takes as long as it makes me money”. While this sounds like a great attitude, it usually reveals that the contractor does not actually know their numbers. Saying this means you likely don’t know your cost per lead, your close rate, or what a booked job actually costs to acquire.
Handing an agency an open checkbook is a wish, not a plan. Your budget needs to be a real number tied to your specific growth goals. Often, contractors expect to spend $2,000 to $3,000 a month, only to discover their actual revenue goals require $15,000 or $20,000. You cannot manage a budget you have not accurately defined.
The Two Questions You Should Ask Instead
To stop guessing and start scaling, figure out your exact budget in about 30 seconds by answering two crucial questions:
1. What mode are you in? Percentages are a starting point, not a final answer.
- Maintain: If your goal is simply to maintain your current position, the recommended floor is 5% of top-line revenue.
- Grow: If you want to grow, you need to push toward 10%.
- Scale: If you are in aggressive growth mode, you should be looking at 10% to 15%.
2. What does your booked job math say? This is the number most contractors have never calculated. Let’s say you are a roofer with an average job value of $18,000.
- If your close rate on estimates is 40%, you need 2.5 estimates to land one job.
- If your lead-to-appointment rate is 25%, you need 10 leads to get those 2.5 estimates.
- At a cost of $200 per lead, it costs you $2,000 to acquire one job.
Crucially, that $2,000 must be measured against your gross profit, not your overall ticket price. If your gross margin is 40% ($7,200), and you pay a 10% sales commission ($1,800), your net gross is $5,400. Subtract the $2,000 acquisition cost, and you are left with $3,400 in real profit per job.
Once you know this, just set your revenue goal. If you want 20 new jobs this month, you need 200 leads. At $200 a lead, your exact, math-produced budget is $40,000.
Stop Guessing, Start Managing
Once you establish this math, your budget conversation and your performance conversation become exactly the same thing. You stop arguing over whether marketing “feels” like it’s working, because working is a number, not a feeling.
When you track your inputs and outputs, you can make real decisions. You can break down performance by channel to see which lead sources are highly profitable and which ones are quietly burning your budget. The most successful contractors are not necessarily the ones spending the most; they are the ones who know exactly what every single dollar is producing.
