A practical, no-fluff guide to what small businesses should actually budget for advertising — by industry, stage, and goal.
The short answer
Most established small businesses spend between 5% and 10% of revenue on marketing and advertising combined. Newer businesses, businesses launching a new product or location, and businesses in highly competitive categories often spend more — sometimes 12% to 20% of revenue — to break through.
That is the rule of thumb. It is not a law. The right number for your business depends on three things: your goal, your competition, and your margin structure.
Goal first, budget second
Before you ask "how much should I spend," answer "what am I trying to make happen?" Common goals look very different at different budgets:
- More phone calls for a service business: usually starts at $1,500–$3,000/mo on a focused mix of search ads, retargeting, and a strong Google Business Profile.
- More foot traffic for a restaurant or retail location: $1,500–$5,000/mo on local awareness (radio + streaming audio) plus geofencing and Meta promotions tied to specific offers.
- More qualified leads for a B2B or higher-ticket service: $2,500–$7,500/mo on paid search, LinkedIn, and retargeting against a clear conversion landing page.
- Brand awareness in a defined market: a meaningful awareness campaign in a Black Hills-sized market typically requires at least $3,500–$10,000/mo across radio, streaming audio, CTV/OTT, and display to actually be heard.
If the goal demands a level of presence the budget cannot support, the campaign will under-deliver. We would rather tell you that on day one than after three months of disappointing reports.
Competition matters more than people realize
Two businesses in the same category can have wildly different ad budgets that are both correct. A solo HVAC company in a small town may need $1,200–$2,000/mo. A multi-truck HVAC operation competing against three well-funded competitors in Rapid City may need $5,000–$8,000/mo just to keep visibility steady.
The question is not "how much do I want to spend?" The question is "what does it take to be visible enough in this market to be considered?" If a competitor is buying every Google search ad, every billboard, every radio sponsorship, and you are running one Facebook ad a week, your spend is technically on the books — but functionally invisible.
Margin structure changes the math
Businesses with high gross margin (most professional services, software, dental, recovery treatment, real estate) can typically afford to spend more on advertising as a percentage of revenue. Businesses with thin margin (restaurants, retail, contractors with heavy material costs) need to be more disciplined and often need to lean on radio + email + organic Google Business Profile work to stretch dollars further.
A practical exercise: figure out the lifetime value of a customer. Then figure out what you are willing to pay to acquire one. If your average customer is worth $5,000 over their lifetime and you are willing to spend up to $400 to acquire one, that gives you the math you need to evaluate whether a campaign is working.
What "spending more" actually buys
When a business doubles its advertising budget, they are not just doubling the number of ads. They are typically getting:
- More frequency (the same audience hears or sees the message more times before deciding)
- More channels (radio + digital + retargeting instead of just one)
- More creative variation (different messages for different audiences)
- More measurement (the larger spend justifies serious analytics setup)
It is not 1+1=2. Often, increasing spend modestly produces disproportionately better results because frequency and channel coverage finally cross the threshold where the campaign becomes memorable.
A starting framework
If you are figuring out where to start, try this:
- Take 5–10% of revenue as the planning number.
- Subtract your existing fixed marketing costs (website hosting, agency fees, software, sponsorships).
- The remaining number is your flexible advertising budget for the year.
- Divide it into 12 months and consider flighting — heavier spend in your busy seasons, lighter in your slow ones.
- Reserve about 70% of the flexible budget for tactics with measurable conversions (search, social, display, retargeting). Allocate the other 30% for awareness and trust (radio, streaming audio, CTV, sponsorships).
That is a starting framework — not gospel. We refine it for your business in the first conversation.
