Published benchmarks put total marketing spend for a small to mid-sized service business somewhere between roughly 7% and 12% of revenue, depending on the survey and whether the business sells a product or a service. That range is a sanity check, not a target to hit. The figure that actually decides whether a budget is working is your customer acquisition cost (CAC) measured against what a customer is worth to you over time (LTV). A rented channel, a paid ad or a shared lead, is easy to judge this way because every dollar has a date and a result attached to it. An owned channel, a Map Pack ranking, your reviews, your own site, costs more upfront and shows a messier number early, but keeps producing without a matching bill every month it holds. Judging both on the same monthly total, without asking what each dollar bought, is how a working budget gets cut and a leaking one keeps getting funded.
By the numbers
- 7% to 12% of revenue is the range published marketing-spend benchmarks land on for a small or mid-sized business, with the low end skewing toward B2B product companies and the high end toward consumer-facing services. INDEPENDENT RESEARCH
- The CMO Survey (Deloitte, Duke University's Fuqua School of Business, and the American Marketing Association) put average 2026 marketing budgets at 9.0% of company revenue, with B2B services companies running higher, at 10.1%. INDEPENDENT RESEARCH
- A 3:1 ratio of customer lifetime value to customer acquisition cost is the commonly cited health benchmark across industries: a customer should be worth roughly three times what it cost to win them. INDEPENDENT RESEARCH
- Google made data-driven attribution the default model for Google Ads conversion tracking in September 2023, retiring the older first-click, linear, time-decay and position-based rules-based models. GOOGLE DOCUMENTED
What published benchmarks actually say
Every major survey lands in a similar band. They differ mostly on who they surveyed, large enterprises skew the average down, smaller and more consumer-facing businesses skew it up.
| Source | Reported figure | Who it covers |
|---|---|---|
| U.S. Small Business Administration INDEPENDENT RESEARCH | 7% – 8% of gross revenue | Small businesses generally, as a rule-of-thumb starting point |
| The CMO Survey (Deloitte / Duke Fuqua / AMA) INDEPENDENT RESEARCH | 9.0% overall; 10.1% for B2B services | A broad mix of company sizes across sectors |
| Gartner CMO Spend Survey INDEPENDENT RESEARCH | 7.8% overall | Mostly large enterprises, a narrower and pricier sample |
| Digital Handshake Media DHM DATA | $1,000 – $3,500 USD/mo typical, published in full | Local service businesses specifically, not a percentage figure |
Notice none of these name a number for your business specifically. A roofer in a competitive metro and a niche inspection service in a small town can both be "on benchmark" at very different dollar figures, because the benchmark is a percentage of very different revenue. Our own pricing page breaks the local-search piece of this down by real dollar figure instead of a percentage, including what a shared-lead platform and paid search typically cost for comparison.
The math that matters more than the percentage
A budget that hits the "right" percentage of revenue can still be a bad budget, and a budget below it can still be a great one. What decides that is two numbers most businesses never write down.
- Customer acquisition cost (CAC). Every dollar spent to win a customer, ads, agency fees, tools, a portion of staff time, divided by how many new customers it actually produced in that period.
- Customer lifetime value (LTV). What one customer is worth to you across every job they book, not just the first one, including realistic repeat work and referrals for trades where that's common.
- The ratio between them. LTV to CAC of roughly 3:1 or better is the widely cited health mark. Below that, growth is expensive. Well above it, a business is often under-investing and leaving bookings on the table.
A worked example (illustrative, not a claim about any real business)
Made-up numbers, to show the shape of the math. Swap in a real average job value and a real number of repeat jobs for your own trade to get a number that means something.
| What you'd track | Channel A (example) | Channel B (example) |
|---|---|---|
| Monthly spend | $2,000 | $2,000 |
| New customers/mo | 4 | 8 |
| CAC | $500 | $250 |
| Average customer LTV | $900 | $900 |
| LTV : CAC ratio | 1.8 : 1 (underwater fast) | 3.6 : 1 (healthy) |
Same monthly bill. Very different budget decision. This is why "we spend $2,000 a month on marketing" is not, by itself, a useful sentence, and why a budget conversation that stops at the total dollar figure is having the wrong conversation.
Why the same dollar doesn't mean the same thing
CAC is easy to calculate cleanly for a rented channel and genuinely harder for an owned one, and that difference trips up a lot of budget decisions.
Every dollar has a date, a click, and usually a lead attached to it, so CAC is close to a real-time number. It also stops producing the same day the spend stops, so the CAC you calculated last month tells you almost nothing about next month if the budget changes.
The cost is front-loaded, the work to build a ranking or a review base, and lighter after that to hold it. A clean monthly CAC number is harder to isolate because the channel keeps producing weeks and months after the work that built it. Judging it on one month's spend against one month's leads understates it badly.
A business that only tracks CAC for the channel that's easy to measure ends up over-funding it and under-funding the one that's harder to measure but often cheaper per job a year in. The fix isn't a better spreadsheet formula, it's measuring both against a longer window: a single month for paid, a 12-week baseline for anything organic. Full detail on that specific trade-off is in the lead gen trap.
Before you cut or add spend
- Write down your real average job value and repeat-work rate. Without it, LTV is a guess and CAC is a number with nothing to compare against.
- Separate rented and owned channels before judging either one. Compare paid CAC to paid CAC, and give an organic channel a full quarter before calling it expensive.
- Run the numbers, don't estimate them. The free ROI calculator models extra jobs and revenue from a Map Pack improvement using your own inputs, not an industry average.
- Re-check at a fixed interval, not on a feeling. A 12-week mark is long enough for an organic channel's early numbers to mean something and short enough to catch a genuinely underperforming spend before it compounds.
Questions we get
Frequently asked questions
How much should a local service business spend on marketing?
Published benchmarks land between roughly 7% and 12% of revenue, with the U.S. Small Business Administration's commonly cited figure at 7-8% and The CMO Survey's 2026 average at 9.0%. Treat that as a sanity check on the total, not a target. The more useful question is whether your customer acquisition cost against what a customer is worth to you supports the spend, not whether the dollar figure matches a percentage.
What's a good customer acquisition cost for a local service business?
There's no single published number, because it depends entirely on your average job value and how often a customer comes back. The useful benchmark is the ratio, not the raw figure: lifetime value at roughly three times acquisition cost or better is the widely cited health mark. A $150 CAC is bad if a customer is only ever worth $200, and a $600 CAC is fine if that same customer is worth $3,000 over a few years.
Is a 3:1 LTV to CAC ratio realistic for every trade?
It's a general benchmark, not a rule specific to home services, and it should flex by trade. A business with genuinely one-off jobs and no repeat work or referrals leans on a single job's margin to clear that ratio; a business with strong repeat and referral work, HVAC maintenance plans, recurring landscaping, has more room. Use your own real numbers rather than assume the benchmark applies exactly as published.
Why is it harder to measure ROI on SEO than on paid ads?
A paid ad's cost and result both land in the same short window, so the math is close to real-time. An owned ranking's cost is mostly upfront, building the profile, reviews and content, and the return shows up over months afterward without a matching monthly bill attached to each call. Comparing the two on one month's numbers alone understates the owned channel and overstates the rented one.
Should my marketing budget be a flat percentage of revenue or tied to jobs?
Percentage of revenue is a reasonable starting range to sanity-check a total budget against. It's a poor way to decide where that budget actually goes. Splitting it by CAC and LTV per channel, not by an even percentage split, is what actually tells you whether a dollar is well spent.
How soon should I expect to see a return?
For paid channels, often within the first billing cycle, the data is close to real-time. For an owned ranking, our own roadmap runs 12 weeks for the first measurable shift, with profile-level work showing movement earliest and prominence-based ranking gains compounding after that. Judging either channel on a shorter window than that produces a misleading number.
