Most business owners ask this question eventually, and the answer they usually get is a percentage of revenue. That's a reasonable starting point — the percentage benchmarks are real and worth knowing. But the number that actually makes sense for your business depends on variables the benchmarks don't account for.
What the Benchmarks Say
The most widely cited rule is 2–5% of gross revenue for businesses trying to maintain their current position, and 10–12% for businesses in growth mode or in competitive categories.
The U.S. Small Business Administration has historically cited 7–8% of revenue as a reasonable target for small businesses with margins above 10–12%. The CMO Survey, which tracks actual spending across industries, puts business-to-consumer companies closer to 14–15% of revenue. Both numbers apply to total marketing spend, not just advertising.
The range is wide because the right number is specific to your situation. Use the percentages as a reference, not a prescription.
The Boise Business Advertising Guide
A practical guide to planning and budgeting local advertising in the Treasure Valley — channels, costs, and how to evaluate what's working.
What Makes the Number Higher
You're a newer business. If customers don't know you exist, you need to spend more to build awareness than an established business spending to maintain it. Early-stage advertising is investment, not overhead. The businesses that underspend in year one often find that they're still unknown in year three.
Your category is competitive. In a category where multiple local businesses are actively advertising — personal injury law, HVAC, mortgage lending — you have to spend enough to be heard. A budget that would be sufficient in a quiet category may be invisible in a loud one.
You're trying to grow, not just maintain. Keeping your current customers requires less advertising than growing your base. If your goal is meaningful revenue growth, your advertising budget usually needs to reflect that ambition.
You're launching something new. Even established businesses need to treat a new service area or product line as an awareness problem, not a conversion problem. A known name in one category is not a known name in another.
What Makes the Number Lower
Referrals are doing a lot of the work. Some businesses get most of their growth from word-of-mouth. If referrals are consistent and your pipeline is full, you need less advertising to generate leads. You still need some — to reach people outside your referral network — but the baseline is lower.
Your customers stay a long time. A business with high retention and long customer lifetimes needs fewer new customers to hit growth targets. Law firms, financial planners, and insurance agencies often work this way. The cost of losing a client is high; winning one matters less in terms of annual spend because they stay for years.
Your category isn't competitive locally. If you're the only provider of something in the Treasure Valley, you're spending to create category awareness, not to win a competitive battle. That's usually cheaper.
Concentration Matters More Than Coverage
Every advertising channel has a threshold — a minimum level of presence needed before the spend produces meaningful results. Below that threshold, you get occasional impressions rather than the consistent frequency that builds familiarity.
This is why a plan that splits a modest budget across many channels often underperforms a plan that concentrates that same budget on one or two. Fewer channels, properly funded, will almost always outperform wider coverage spread thin. Once you've proven results on one channel, adding another is much less risky than trying to run several at once.
What "Properly Funded" Looks Like in the Boise Market
This varies by channel, but some rough benchmarks for the Treasure Valley:
Radio: A campaign that builds real frequency — meaning someone hears your message enough times to remember it — is achievable for around $1,000 per month on a single station in this market. For businesses with a tighter budget, we've built campaigns starting at $500 a month that reach a smaller audience but hit it with enough frequency to stick. Most campaigns expand from there as results come in.
Search advertising: In competitive categories like HVAC, law, or mortgage, cost-per-click is high enough that $500/month doesn't stretch far. You need enough budget to show up consistently, not just occasionally.
Digital display and streaming: Minimum effective budgets are generally lower, but reach is also more limited at entry-level spend. These channels typically work better as a complement to something broader rather than a standalone plan.
The Boise Market Is Still a Relative Bargain
One advantage of advertising in the Treasure Valley: you're not in Los Angeles, Seattle, or Denver. The Boise market is large enough to matter — over 800,000 people across the metro — but small enough that the cost to reach those people is still reasonable compared to larger markets.
That gap won't last forever. The market is growing fast, and advertising costs tend to follow population. Businesses that establish presence now — while the cost is still accessible — are building something that compounds. The Treasure Valley's growth trajectory makes the case for moving early rather than waiting.
A Practical Way to Set Your Number
Start with the percentage benchmarks as a reference. Then ask two questions: What does it actually cost to be effective on the channel I've chosen? And what growth am I trying to produce?
If the budget that feels comfortable is below the threshold for the channel you're considering, you have three options: increase the budget, choose a less expensive channel, or accept that results will be limited.
The worst option is spending a comfortable amount on an expensive channel and concluding that advertising doesn't work. Most underperforming campaigns share structural problems — wrong channel, wrong budget, wrong timeline — rather than something wrong with advertising itself.
