How Much Should a Home Service Business Spend on Marketing? (The Real Answer)

Someone told you to spend 10% of revenue on marketing. Maybe it was a consultant. Maybe you read it somewhere. You ran the number, looked at what that actually meant to write a check for, and it felt either wildly high or suspiciously low depending on where your business is right now.

That instinct is worth listening to.

Where the 10% Rule Actually Comes From

The 10% benchmark didn't come from home service businesses. It came from companies that already have a working marketing system, know what a new customer costs them, know which channels are producing, and are adjusting something that's already running. For those businesses, 10% is a maintenance number. They're spending to keep doing more of what works because they already know what that is.

Most home service businesses are still working that part out. Which jobs do you actually want? Which customers come back and send referrals? Which marketing activities are producing revenue versus just producing activity? Setting a budget as a percentage of revenue before you can answer those questions means you're picking a number out of thin air and calling it a plan.

The Two Numbers That Tell You What to Spend

Before any budget conversation, you need to know two things.

The first is what it costs you to get a job right now. Add up what you spent on marketing last year, divide by the number of jobs that came from it, and you have a rough cost per acquired job. If most of your work comes from referrals and costs you almost nothing, that changes the math considerably. If you're running ads and you don't know this number, you genuinely don't have enough information to decide what to spend next.

The second is what a customer is worth to you over time. A one-and-done HVAC service call and a relationship with a homeowner who calls every spring and sends two neighbors are worth completely different amounts. A business built on repeat work can afford to spend more acquiring a new customer because that customer keeps paying. A business doing transactional jobs that rarely repeat has to be much tighter.

Those two numbers together tell you what a customer is worth to acquire and what you can afford to spend getting one. The percentage of revenue question is the wrong place to start. These are the right ones.

What the Budget Looks Like at Different Stages

Under $500K, marketing spend matters less than job selection, referral cultivation, and making sure you're doing work that generates more work. The most effective marketing at this stage is often the cheapest: a tight Google Business Profile, a consistent process for asking happy customers for reviews, showing up reliably for the people you already have. Spending $3,000 a month on ads before you know your best job type or your best customer is burning cash your operations actually need.

From $500K to $2M, you have enough history to make smarter decisions. You probably know which channels send you the best customers, which job types are most profitable, where your referrals come from. This is the range where a real marketing strategy starts paying off quickly because you're building on actual data instead of guessing. Investing in the channels that are already producing, and building systems to capture and convert more of the leads you're already getting, moves things materially at this stage.

Above $2M, you're leaving money behind without a strategy. Your reputation is doing real work. The question becomes how to build on it systematically, and that's where knowing your acquisition cost and lifetime value becomes important. Businesses at this stage usually find they're underinvesting in the channels producing their best customers and overinvesting in channels that produce volume with no margin.

The Mistake That Costs More Than Overspending

Overspending is rarely the real problem. Spending without a hypothesis is. A business runs Google Ads for six months, doesn't track which ads produced which jobs, can't tell whether the calls converted or what they were worth, and then decides to keep going or stop based on feel. That's an information problem, and no amount of budget adjustment fixes it.

Without that, any number you pick is arbitrary, and you'll have no idea whether it worked when you look back at it a year later. That's exactly why marketing spend so often feels like throwing money at things, because there was never a hypothesis to measure against.

What to Do Before You Set a Number

Pull your jobs from the last twelve months. Which ones were most profitable? Where did they come from? How much did you spend to get them? Which customers came back or sent someone else?

If you've been running paid marketing, figure out your cost per acquired job from each channel. If you haven't, your baseline is whatever you've been doing to get the work you already have, and you can build from there.

Then figure out what you're trying to add. If you want ten more jobs a month at your current mix, the question is what those ten jobs cost to produce from the channel you're planning to use. That math gives you a starting budget. A revenue percentage doesn't.

If you're not sure whether you even need a marketing strategy yet, that's often a sign the answer is yes.

A Realistic Starting Place

For most home service businesses in the $500K to $3M range that are starting to invest in marketing with some intention behind it, somewhere between $1,500 and $4,000 a month is a reasonable starting point once you know your numbers. That gives you enough to actually test something, see what it produces, and make a real decision about whether to scale it up.

The number matters less than knowing what it's supposed to do. Spend whatever you decide to spend without a strategy underneath it, and you'll end up in the same place twelve months from now, trying to explain a year's worth of invoices with no clear answer for what they bought you.
