What's a Good Ad Budget for a Local Small Business?

"How much should I spend on ads?" is the question every local small business owner asks first, and the one most agencies dodge. Here are the real 2026 benchmarks by industry, the minimum viable starting number, and the simple math that tells you when it's time to scale up.

The minimum viable ad budget

Do not run ads with less than $500 per month in media spend, per platform. Below that, the algorithms on Google, Facebook, and Instagram don't get enough conversion data to optimize, and you end up paying for random impressions instead of qualified leads. If $500/mo isn't in the budget yet, put that money into organic content or SEO first and come back to ads later.

2026 benchmarks by industry

• Home services (plumbing, HVAC, electrical, roofing): $1,500-$5,000/mo, mostly on Google
• Restaurants and food & beverage: $500-$2,000/mo, mostly on Instagram and Facebook
• Health, fitness, and wellness: $1,000-$3,000/mo, split between Google and Meta
• Professional services (accountants, lawyers, consultants): $1,500-$4,000/mo, mostly on Google
• Retail and boutiques: $800-$2,500/mo, mostly on Meta and Google Shopping
• Real estate agents and brokers: $1,000-$3,000/mo, split across Meta and Google

These are starting ranges. Successful businesses in each category often scale to 2-5x these numbers once they've proven what a lead is worth.

The simple math for setting your budget

Start with two numbers: what is one new customer worth to you (average order value or lifetime value), and what percentage of that value are you willing to spend to acquire them? Most local businesses can profitably spend 10-25% of first-order value on acquisition. If a new customer is worth $800 to you on their first purchase, you can afford roughly $80-$200 in ad spend to acquire them. Multiply by how many new customers you want per month and you have your starting budget.

The 90-day rule

Commit to a fixed monthly budget for at least 90 days before you judge whether ads work. Month one is learning, month two is optimization, month three is when consistent results actually show up. Cutting the budget in month one because "it's not working yet" is the single most expensive mistake small business owners make with paid ads.

When to scale up

When your cost per lead has been stable for at least 30 days and your closing rate on those leads is healthy, you can typically increase budget by 20-30% per month without breaking performance. Bigger jumps than that reset the algorithm's learning and often make results worse for 2-3 weeks.
