A good small business marketing budget starts with one question: how many new customers do you need next year? Work backward from that number, check it against published benchmarks, and put money first into the assets you own. This guide walks you through each step for 2027, with no guesswork and no sales pitch.
In short:
- Start from your goals: what a customer is worth and how many you need.
- Sanity-check the total against published guidance, often 2 to 10 percent of revenue depending on your type of business.
- Include everything: website, tools, ongoing visibility work, ads and your own team’s time.
- Fund the foundation (website, Google profile, SEO) before the amplifiers (ads).
- Track every lead back to revenue so next year’s budget is easier.
What the benchmarks say
There is no single right number. Published guidance gives a useful starting range, as a share of revenue:
| Source | Guidance | Who it describes |
|---|---|---|
| BDC (Canada’s business development bank) | 2 to 5 percent of revenue | Business-to-business companies |
| BDC | 5 to 10 percent of revenue | Business-to-consumer companies |
| Gartner 2026 CMO Spend Survey | 7.8 percent of company revenue on average | Large companies, mostly over a billion in revenue |
You can read the details in BDC’s guide to small business marketing budgets and Gartner’s 2026 CMO Spend Survey summary.
Most medical and dental practices, law firms and home service businesses serve consumers directly, so they often land in the consumer range. Businesses in a fast-growth year, entering a new market or launching a new location often plan toward the higher end. Steady, well-established businesses with strong referrals may sit lower.
Use these ranges as a check, not a starting point. The better starting point is your own numbers.
Step 1: Start from the customers you need
Work out what a customer is worth
Look at your average revenue per new customer over the time they stay with you. A dental patient may visit for years. A law firm client may hire you once but refer others. A homeowner may call you for repairs, then sign up for a maintenance plan. Include repeat work and referrals if you can estimate them.
Decide what you can afford to spend to win one
Look at your profit margin on that customer. The amount you are willing to spend to win one new customer should leave room for a healthy profit. This number is your target acquisition cost.
Decide how many new customers you need
Look at your growth goal for 2027. How many new customers does it take to get there, after accounting for customers you will naturally lose? Be realistic about your capacity to serve them.
Multiply
New customers needed, multiplied by your target acquisition cost, gives you a goal-based budget. Then compare it with the benchmark range for your type of business. If the two are far apart, revisit your assumptions.
A quick example in plain numbers
Say your goal requires 120 new customers next year, about 10 a month. You know from past records that roughly one in three qualified leads becomes a customer. That means you need about 30 qualified leads a month. Now you can ask a much better question than “what should we spend?” You can ask, “what will it take to produce 30 good leads a month, and what can we afford to pay for each one?” That turns budgeting into a plan you can measure.
Step 2: List everything that belongs in the budget
Many budgets come up short because they leave things out. Use this checklist:
Foundation
- Website: hosting, security, maintenance and updates.
- Website rebuilds: if your site is due for a redesign, spread that cost over the years you expect to use it.
- Google Business Profile: photos, posts and review management time.
- Tools: email marketing, CRM, call tracking, scheduling and analytics.
Ongoing visibility
- SEO and content: service pages, articles, local listings and technical upkeep.
- Reviews and reputation: the system for asking, monitoring and replying.
- Email and customer follow-up: newsletters, reminders and referral asks.
Amplification
- Paid search and social ads: keep these as their own line so you can turn them up or down.
- Sponsorships and events: community visibility that also earns local links and goodwill.
The costs people forget
- Your own time and your team’s time spent on marketing.
- Photography and video.
- Printing, signs and vehicle graphics.
- A small reserve for opportunities or surprises.

Step 3: Split the budget across channels
Fund the foundation first
Ads, social posts and email all send people to your website and Google profile. If those are slow, unclear or out of date, every other dollar works harder than it needs to. Make sure the foundation is solid before you add more traffic.

Lean toward channels you own
Paid ads and SEO work differently. Ads buy attention month to month. SEO, reviews and your customer list build assets you own, and those assets keep producing after the work is done. A budget weighted toward owned channels tends to get more efficient each year. Our SEO services page explains how that compounding works.
Keep some room to test
A common rule of thumb is 70-20-10: about 70 percent on channels that already work, 20 percent on growing promising ones and 10 percent on experiments. Adjust it to your situation, but protect a small amount for testing.
Plan for seasonality
Most businesses have busy and slow seasons. In the Charleston area, for example, home service demand often climbs with summer heat and storm season, and many practices see shifts around school calendars and holidays. Spend ahead of your busy season so visibility is in place when demand arrives, and use slow seasons for content and website improvements.
A sample allocation framework
Here is one way to think about the split, by category, as a share of your total marketing budget. Your numbers will differ, but the order of priorities usually holds.
| Category | What it covers | Typical priority |
|---|---|---|
| Foundation | Website care, hosting, tools, Google profile | Fund first; keep steady all year |
| Ongoing visibility | SEO, content, reviews, local listings | Largest share for most local service businesses |
| Customer follow-up | Email, reminders, referral programs | Small but high return |
| Amplification | Paid ads, sponsorships | Flexible; scale with results and season |
| Testing and reserve | New ideas, surprises | Small, protected slice |
To compare ongoing options, our CORE program plans page lays out what each level includes. For the website portion, see our website hosting and care page.
Step 4: Track it so next year is easy
Track calls as carefully as clicks
For many local businesses, phone calls are the biggest source of new customers. Use call tracking on your website and check the calls report in your Google Business Profile. Leads you cannot see are leads you cannot credit to the right channel.
Connect leads to revenue
Counting leads is a start. Knowing which leads became paying customers, and how much they spent, is what lets you budget with confidence. A simple CRM field for “lead source” on every new customer goes a long way.
Give channels enough time
Paid ads show results within weeks. SEO and content usually take several months to build. Judge each channel on a fair timeline before you cut or boost it.
Write down what you expect
Before the year starts, note what you expect each channel to produce. At each quarterly review, compare actual results with your expectations. Those notes make next year’s budget a much easier conversation.
How budgets differ by type of business
The same framework works for everyone, but the priorities shift a little by industry.
Medical and dental practices
Patients choose from the map and reviews, so the Google profile, review system and one clear page per service usually come first. Budget for patient-safe tools too: forms, scheduling and tracking that protect health information. Recall reminders to existing patients are often one of the highest-return lines in the budget.
Law firms
Many firms are referral-driven, and referred clients still look you up before calling. Budget for strong practice-area pages, attorney bios, reviews and helpful articles that answer common legal questions in plain language. Fast intake and follow-up matter as much as visibility.
Home service businesses
Demand is often urgent and seasonal. Fund the Google profile, service and area pages and a fast-response system first. Paid ads can help during peak season or for a new service line. Your past-customer list deserves its own line for seasonal reminders and maintenance plans.
Questions to answer before you finalize
- Which channel brought in the most new customers this year, and do we know for sure?
- Is our website fast, clear and easy to use on a phone, or does it need work first?
- Which services do we most want to grow next year?
- Do we have the staff to handle more calls and leads?
- Who will own the budget and review it each quarter?
- What would we cut first if revenue came in lower than planned?

Your 2027 budget checklist
- Write down your revenue goal and how many new customers it requires.
- Estimate what a customer is worth and what you can spend to win one.
- Calculate a goal-based budget and compare it with the benchmark range.
- List every cost, including tools, your team’s time and website care.
- Fund the foundation first, then ongoing visibility, then ads.
- Protect a small slice for testing.
- Map spending to your busy and slow seasons.
- Set up tracking for calls, forms and revenue by source.
- Schedule quarterly reviews on your calendar now.
Common budgeting mistakes to avoid
- Budgeting from last year’s number alone. Start from this year’s goals instead.
- Leaving out the website. It is where most of your marketing sends people.
- Judging SEO after a few weeks. Give it a fair timeline.
- Not tracking calls. You will undervalue the channels that work best.
- Spreading too thin. Doing three channels well beats doing eight poorly.
