How Much Should a Small Business Actually Spend on Marketing?

Most small business owners set their marketing budget the same way: whatever’s left over after rent, payroll, and inventory. If there’s $500 left, that’s the marketing budget. If there’s nothing left, marketing waits until “things pick up.”

That approach has it backwards. Marketing isn’t the leftover — it’s what makes there be something left over in the first place.

So what’s the right number? Not a guess, not a gut feeling, but an actual benchmark you can work from.

The Short Answer: 7–8% of Revenue, With Exceptions

The U.S. Small Business Administration recommends businesses under $5 million in annual revenue spend 7–8% of gross revenue on marketing. That’s the most commonly cited starting point, and for a stable, established small business, it’s a reasonable place to begin.

But that number moves depending on where your business actually stands:

• Startups and businesses under two years old: 12–20% of revenue. You have no brand recognition yet, so you’re paying to build awareness from zero.
• Businesses in crowded, competitive markets (e-commerce, local services with five competitors on the same street, SaaS): lean toward the higher end of any range, or above it.
• Established businesses with strong repeat customers: can often run closer to 5%, since word-of-mouth and retention are doing part of the job marketing would otherwise have to do.

Industry-wide, small businesses typically land somewhere between 5% and 20% of revenue — a wide range, because “small business” covers everything from a solo consultant to a 40-person company doing $4 million a year.

Why the Percentage Isn’t the Real Answer

Here’s the part most budget guides skip: benchmarks tell you what other businesses spend, not what you need to spend to hit your goal.

A better way to set your number is to work backward from what you actually want:

1. Decide how many new customers you need this year.
2. Figure out what one customer is worth to you (average sale, or lifetime value if they return).
3. Estimate what it currently costs you to acquire one customer through your best channel.
4. Multiply that cost by the number of customers you need.

If you need 50 new clients, each worth $2,000 in profit, and your acquisition cost per client is roughly $300, you’re looking at a $15,000 marketing investment to hit that growth target — regardless of what percentage-of-revenue math says.

Percentage benchmarks are a sanity check. Funnel math is the actual budget.

Where the Money Should Go First

Not all marketing spend returns the same. Based on 2026 small business data, the highest-ROI channels for most small businesses are:

• Email marketing — consistently the highest return of any channel, largely because it’s low-cost and reaches people who already know you.
• Local SEO and organic search — slower to build, but the cost per lead drops sharply once it’s working, which is exactly why a content-driven site like this one compounds over time instead of resetting every month like paid ads do.
• Paid social and search ads — fast, but only efficient once you know your numbers. Don’t scale ad spend before you’ve confirmed what converts.

A common mistake: spending on the flashiest channel (paid ads, influencer campaigns) before the cheap, reliable ones (email, SEO, referrals) are even set up. Fix the foundation first — it makes every dollar spent on top of it work harder.

The Real Small Business Marketing Problem

The bigger issue isn’t which percentage is “correct” — it’s that most small businesses spend far below any of these benchmarks. A large share of small business owners spend under $1,000 a year on marketing total, which is well below the threshold where marketing starts producing consistent results.

Underspending doesn’t just slow growth — it often wastes the little that is spent, because scattered, inconsistent effort rarely gets a channel to the point where it starts working.

How to Set Your Own Number

If you’re not sure where to start:

• Under $5M revenue, stable business: aim for 7–8% of revenue as a baseline.
• New business or aggressive growth goal: budget 12–20%, treating early spend as an investment in visibility rather than expecting immediate payback.
• Tight cash flow: don’t cut to zero. Even a small, consistent monthly spend on one working channel outperforms a large one-time push followed by silence.

The number matters less than the consistency. A business spending 5% of revenue every month, every year, will usually outgrow one that spends 15% for two months and then stops.
