How Much Should a Small Business Spend on Marketing?
A common rule of thumb is 5 to 10 percent of revenue, with established businesses in steady markets toward the low end and new or fast-growing businesses spending more, sometimes 12 to 20 percent for a period. A better method is to work from the numbers: decide how many new customers you need, estimate what each costs to acquire, and check that cost against each customer's gross profit. The SBA advises building a line-item marketing budget and tracking it against the revenue it generates.
- Percent-of-revenue is a sanity check, not a strategy.
- Budget from customer acquisition cost and customer value, not from last year's spend.
- New businesses usually need to spend more as a share of revenue to get known.
- Reserve 10 to 20 percent of the budget for testing new channels.
- Count tools, agency fees and staff time, not just ad spend.
The Rules of Thumb, and Their Limits
The figure most often quoted is 5 to 10 percent of gross revenue. It is a reasonable starting point and a useful check against both underspending and runaway spend. It is not an official standard, and it ignores the things that actually determine the right number: your margins, how fast you want to grow, how competitive your market is and how much each customer is worth over time.
The U.S. Small Business Administration's guidance on marketing and sales does not prescribe a percentage. It recommends a marketing plan with a complete breakdown of costs, tracked as you execute, and a comparison of marketing costs against the revenue they generate so you know your return on investment. That is the right frame.
Some general patterns hold across most small businesses:
- New businesses often spend a larger share, sometimes 12 to 20 percent of revenue in the first year or two, because nobody knows them yet.
- Established businesses with strong referrals can often sustain growth at the low end.
- High-margin businesses (many professional services, med spas, specialty contractors) can afford to spend more per customer than low-margin ones such as restaurants or retail.
The Better Method: Work From Customer Value
Instead of starting with a percentage, start with the customers you need and what you can afford to pay for each one.
- Estimate customer value. Average gross profit per customer over a realistic period. A pool service client paying $150 a month at 50 percent margin who stays two years is worth about $1,800 in gross profit.
- Set an acceptable acquisition cost. Many businesses aim to spend no more than a third of that value to win a customer. Here, roughly $600.
- Set a growth target. If you want 10 new clients a month, that implies about $6,000 a month of total marketing cost at that acquisition cost.
- Check it against revenue and cash flow. If that number is far above 10 to 15 percent of revenue, either the target is too aggressive for your cash position or you need cheaper channels first.
The marketing ROI calculator runs this math for you. The point is that the budget becomes a consequence of your goals rather than a guess.
What Counts as Marketing Spend
Owners often undercount. A complete budget includes:
- Media: Google Ads, Local Services Ads, social ads, sponsorships, print and radio.
- Services: agency retainers, freelancers, photographers, copywriters.
- Software: CRM, email and SMS platforms, scheduling, review tools, website hosting.
- Content and assets: website updates, video, signage, vehicle wraps.
- Staff time: the hours you or your team spend on marketing have a real cost.
Tracking all of it is the only way to know your true cost per customer.
How to Split the Budget
There is no universal split, but a sensible pattern for a local service business looks like this:
- Foundation first: a fast, clear website, a complete Google Business Profile, review generation and a CRM to follow up on leads. These make every other channel work better and cost relatively little.
- Demand capture: paid search and Local Services Ads for people already looking for what you sell. This is usually where the fastest return is.
- Compounding channels: SEO, content and email, which take months but lower acquisition cost over time.
- Testing reserve: 10 to 20 percent of the budget for new channels, offers or audiences, with a clear stop rule.

Review Monthly, Commit Quarterly
Look at cost per lead and cost per customer by channel each month, but avoid making big cuts on a few weeks of data, especially for SEO and content. Make larger reallocations quarterly. Move money toward the channels with the lowest cost per customer that still have room to scale, and away from those that only look good because they get last-click credit. Our guide on measuring marketing ROI explains how to compare channels fairly.
Seasonality matters too. A South Florida HVAC company might front-load spend before summer, while a tax preparer concentrates it in the first quarter. Budget to when customers buy, not evenly across the calendar.

Related Questions
Does the SBA recommend a specific marketing budget percentage?
The SBA's current business guide does not set a fixed percentage. It recommends a marketing plan with a complete, accurate cost breakdown, ongoing tracking, and comparing marketing costs to the revenue they generate to confirm a positive return. Percentages you see quoted are industry rules of thumb.
How much should a startup with no revenue spend on marketing?
With no revenue, a percentage rule does not work. Budget from your runway and your validation goals instead: spend enough to test whether a channel can produce customers at an acceptable cost, then scale what works. Small, measured tests protect cash while you learn.
Should marketing spend go down when sales are slow?
Cutting marketing during a slowdown often deepens it, because the pipeline for future months dries up. A better approach is to cut the channels with the worst cost per customer and protect the efficient ones. Review the numbers before cutting across the board.
Is a marketing agency fee part of the marketing budget?
Yes. Agency retainers, freelancer fees and software subscriptions are all marketing costs. Leaving them out understates your true cost per customer and makes channels look more profitable than they are. Track media spend and service fees separately so you can see both.
