How Much Should a Small Business Spend on Marketing?

Founders ask this constantly. The honest answer isn’t a single number — it’s a range, a stage, and a clear list of what the money is supposed to buy.

If you’re running a small business in Orange County (or anywhere) and you’ve been guessing at a monthly marketing number, this is the practical frame I use with clients.

The short ranges most small teams can use

Industry rules of thumb aren’t gospel, but they’re useful starting points:

• Stable, local, service businesses: often 5–10% of revenue on marketing (ads + tools + help)
• Growth-mode or competitive niches: often 10–15% — sometimes more for a short push
• Brand-new or pre-profit: think in absolute dollars you can afford to test for 90 days, not a perfect percent

Example: a $40k/month service business at 8% is about $3,200/month. That’s enough to fund tracking, one paid channel, and light creative — if you’re disciplined. It’s not enough for an agency roster and six platforms at once.

Budget isn’t one bucket — split it

“Marketing spend” gets fuzzy fast. Separate it:

1. Media / ads — Google, Meta, local sponsorships, whatever actually reaches customers
2. Tools — analytics, CRM, email, landing pages, creative software
3. People — consultant, freelancer, fractional help, or your own time (time is still a cost)

A common mistake: dumping almost everything into ads with broken tracking and no owner of the plan. Then the “budget” looks high and the results look random.

What to fund first (before you scale spend)

Before you add another $1,000 to ads, make sure these are covered:

• Offer clarity — who it’s for, what you sell, why someone should care
• Tracking — leads, cost-per-lead, and a path to revenue (not just clicks)
• One primary channel — the place your buyers already look, run consistently
• A simple landing path — page or form that matches the ad or post

Skipping those and “just spending more” is how small teams burn months. More budget on a fuzzy offer is still a fuzzy offer.

When “percent of revenue” fails

Percentages break in a few common cases:

• High ticket, low volume — a few clients pay the bills; you may spend more percentage-wise on acquisition and still win
• Seasonal businesses — spend ahead of the busy season, not only when cash is flowing
• New offers — treat the first campaigns as tuition; cap the experiment, don’t pretend it’s already optimized

Also: if revenue is tiny, a “recommended” percentage can still be too small to learn anything. Better to fund one clean test than sprinkle $200 across five channels.

How to know if you’re under- or over-spending

You’re probably under-spending if demand is soft, competitors show up everywhere you don’t, and you have capacity to take more work — but you’re “waiting until things pick up” to market.

You’re probably over-spending (or spending wrong) if you can’t name your cost-per-lead, creative and landing pages haven’t changed in months, and you’re adding channels because the last one “felt quiet.”

Money isn’t the only lever. Focus and measurement usually unlock more than another invoice to Meta.

Bottom line

Most small businesses I work with land somewhere in the 5–12% of revenue range once they’re past pure survival — with a bias toward funding tracking, one channel, and clear ownership of the plan before stacking more spend.

The goal isn’t to hit a famous percentage. It’s to know what every dollar is supposed to produce, and to stop funding activity that can’t answer for itself.
