Ask ten vendors what your practice should spend on marketing, and you’ll get ten answers that all happen to equal their retainer. Here’s the version with math you can check.
The benchmarks: an established practice defending its position spends 3–5% of annual production on marketing. A practice in growth mode spends 6–10%. A new practice or new location spends 10%+ for the first 18–24 months, front-loaded. Those ranges hold up across real accounts, run and audited; they’re a starting point, not a law.
But percentages are how people talk about budgets. They’re not how you should set one.
Build the Budget Backward From a Consultation
The right budget is whatever profitably buys the consultations your chairs can absorb. Work it in four steps:
- What’s a start worth? Most practices: $5,000–$7,000 in production.
- What’s a consultation worth? Multiply by your consult-to-start rate. At 65% close and $6,000 cases: ~$3,900 of expected production walks in with every consult.
- What does a lead cost to buy — and what share of leads book? In Midwest markets, well-structured local campaigns produce leads — phone calls lasting 60+ seconds and completed consultation requests — in the $20–$50 range depending on market and intent. Poorly structured accounts in those same markets routinely pay $60–$90 for the same click prices. The difference is structure, not budget. Then apply your front desk’s booking rate to turn lead cost into consultation cost. Organic and GBP leads cost effectively $0 marginal once the work is done.
- How many more starts do you actually want? If the answer is 8 more starts a month at a 65% close, you need ~12 consultations. Work backward through your booking rate to the lead count, multiply by your cost per lead, and that’s your productive ad spend — plus management, plus the foundation work.
Run those four numbers and the budget stops being a negotiation with your own anxiety. It’s an order quantity.
A Sample Budget: $1.5M Single-Location Practice in Growth Mode
- Google Ads spend: $2,000–$3,000/mo — the lead engine
- Management/operator: $2,000–$3,000/mo — the difference between the $18 lead and the $69 one, in the same market at the same click prices
- Local SEO & content: folded into management or ~$500–$1,000/mo standalone — compounds; the only line whose cost per lead falls every quarter
- Call tracking & tooling: ~$100–$200/mo — non-negotiable; without it nothing above can be evaluated
- Total: ~$55K–$85K/year ≈ 4–6% of production — and every line reports a cost per lead, reconciled monthly against the front desk’s booking log
What’s deliberately not in it: billboards, radio, sponsorship bundles, and social-media retainers — not because they never work, but because they go in after the measurable core converts, never before, and only with tracking attached.
The Two Budget Mistakes That Cost the Most
Underspending on a working channel. This one hides in a report column nobody reads: impression share lost to budget. It tells you what share of the searches you could have appeared for you didn’t, because the money ran out. It’s common for a campaign producing profitable leads to be turning away half its available demand this way — which is not thrift, it’s a cap you set in January and forgot. If a campaign’s lead cost is profitable against your case math, the ceiling should be chair capacity, not the budget field.
Spending anything unmeasured. The practices in trouble aren’t the ones spending 10%. They’re the ones spending 5% with no idea which half works. An unmeasured budget isn’t conservative — it’s untested.
FAQs
What percentage of revenue should an orthodontic practice spend on marketing?
3–5% of production to maintain, 6–10% in growth mode, more for a new location. But the per-consultation math above beats any percentage rule.
What’s a good cost per lead for an orthodontic practice?
A well-structured local campaign should produce phone-call and consultation-request leads for under $50 in most Midwest markets. Above $60, the problem is almost always account structure, not the market — usually broad match keywords quietly matching competitor names and unrelated searches. Your true cost per booked consultation is that lead cost divided by your front desk’s booking rate — which is why the booking rate is a marketing number, not just a front-desk number.
Does a small practice need a marketing plan document?
You need the four numbers in this article, written down, reviewed monthly. A 30-page plan nobody opens is decoration; a one-page sheet with case value, close rate, cost per lead by channel, booking rate, and this month’s count is a marketing plan.
