How Much Should a Small Business Spend on Marketing?
The honest answer: how much should a small business spend on marketing — start at 7–8% of revenue if you are established, 10–15% if you are growing, and 5% if you are purely defending. That is not a guess: companies of all sizes sit at about 7.7% of revenue, per Gartner's 2025 CMO Spend Survey of 402 marketing leaders, and the U.S. Small Business Administration's widely used guidance for businesses under $5 million in revenue with healthy margins points to the same 7–8% band. The rule is simple because the inputs are: your stage, your margin, and your goal.
The one-rule version, and when to bend it
Default: 7–8% of revenue. Bend it down to 5% when you are mature, margins are thin, and you are holding market position — bend it up to 10–15% when you are in your first couple of years and need to buy customers and awareness. The two levers that override everything: margin (you cannot out-market a business with zero margin to reinvest) and goal (a flat pipeline is a maintenance budget; a build-out is a growth budget).
By stage
| Stage | % of revenue | Why | Example: $200k/year |
|---|---|---|---|
| Launch (first 12 months) | 12–20% | Buying your first customers, no brand equity yet | $24k–$40k |
| Early growth (0–$1M) | 10–15% | Testing channels, aggressive acquisition | $20k–$30k |
| Established ($1M–$5M) | 7–8% | The SBA default — sustain and compound | $14k–$16k |
| Mature / defensive | 5–7% | Protecting position, optimizing efficiency | $10k–$14k |
What the money is for: the 60/30/10 split
Percent of budget beats vibes: 60% core — the assets that compound: reviews, Google Business Profile, your website, and one paid channel you've already proven. 30% testing — new channels with a defined kill criterion (measure cost per lead against job value, on the timeline in how long until ads start working). 10% tools and overhead — scheduling, a small CRM, design. Owners who "don't have a marketing budget" almost always have the 10% — the missing 90% is just allocation discipline.
Referral-heavy businesses get a discount — with a catch
If your pipeline is mostly word-of-mouth, you can absolutely run leaner — many healthy referral businesses run 3–5% of revenue on acquisition. The catch: that lean number only works if at least a slice of it goes to the visibility layer that keeps referrals alive — reviews, profile, and an answer-ready website. That's the exact argument in why your old marketing stopped working: the channels changed, but the compounding assets didn't. Revenue-perfect referral math still dies on a thin review profile.
Worked example: the $100k service business
Annual revenue $100,000, established, 12% net margin. The rule says 7% — $7,000/year, about $580/month. Split: $350/month core (review requests + a local search presence + website upkeep), $175/month testing (a Local Services Ads budget or one Meta campaign from the worth-it test plan), $55/month tools. One extra $600 job booked per month pays for over 100% of the entire budget — that's the bar every line item has to clear.
The AI footnote
AI doesn't lower your marketing budget; it raises what each dollar returns. 58% of small businesses already use generative AI — up from 40% the year before — and 96% plan to adopt emerging tech, according to the U.S. Chamber's 2025 Empowering Small Business report. Meaning: the 7% number holds, but the execution cost inside it drops — captions, follow-up, review responses, and estimates take a fraction of the time they did two years ago. The owners who win spend the same percentage and compound the savings back into more core assets.
Frequently asked questions
Is 5% of revenue enough for marketing?
For a mature business with healthy referrals, yes — provided some of it still feeds visibility: reviews, profile, website. Below 5% you stop compounding and start relying on luck.
What if my margins are thin?
Scale the percentage to what you can sustain and make the budget ruthless: cut any line item that doesn't tie to cost per lead or booked jobs. A consistent 3–4% that converts beats a heroic 10% you abandon in month two.
Should service businesses spend more or less than retail?
Service businesses with steady referrals can run at the low end (5–7%) because each customer is high-value and repeatable. Retail and restaurants usually need 8–12% because they depend on constant new foot traffic.
How do I split my marketing budget between channels?
Use the 60/30/10 rule: 60% to proven core assets, 30% to testing one new channel at a time, 10% to tools. Only move a tested channel into the core when it beats your cost-per-lead bar.
