Marketing budget calculator
Work backwards from the revenue you want to the budget it takes to get there.
Your numbers
- New patients needed / month
- 25.0
- Leads needed / month
- 71
- Suggested monthly budget
- $5,357 – $10,714
Show the math
- Patients needed = $30,000 ÷ $1,200 = 25.0
- Leads needed = 25.0 ÷ 35% close rate = 71
- Budget range = 71 leads × $75–$150 blended cost-per-lead for Houston dental
Illustrative example — figures are hypothetical. Your cost-per-lead depends on channel mix, competition in your zip code, and how fast your front desk answers the phone.
How goal-backwards budgeting works
Most practices budget one of two ways: a percentage of revenue, or last year's spend plus a bump. Both share the same defect — the number has no relationship to the goal. A budget of $6,000 a month is neither right nor wrong until you know what it's supposed to buy.
Goal-backwards budgeting starts at the end and walks the chain in reverse:
The percentage-of-revenue shortcut isn't useless; it becomes the sanity check at the end. Healthy practices typically invest 5–10% of total revenue in marketing. If the chain above lands far outside that band, one of the inputs is probably wrong — most often the close rate, which owners consistently overestimate.
Worked example: from a $60,000 goal to a monthly budget
Illustrative example — figures are hypothetical.
Take a general practice in Katy with a goal of $60,000/month in new-patient production:
| Step | Math | Result |
|---|---|---|
| Revenue goal | set by the owner | $60,000 |
| Average case value | blended across services | $3,500 |
| Cases needed | 60,000 ÷ 3,500 | 17.1 → 18 cases |
| Close rate (consult-to-start) | measured over 90 days | 50% |
| Consults needed | 18 ÷ 0.50 | 36 consults |
| Lead-to-consult conversion | inquiries that become booked consults | 60% |
| Leads needed | 36 ÷ 0.60 | 60 leads |
| Cost per lead (blended) | paid search + referral + organic mix | $150 |
| Monthly budget | 60 × 150 | $9,000 |
Sanity check: if the practice produces $1.5M a year, $9,000/month is 7.2% of revenue — inside the 5–10% band. The math holds together, and every step points at something the practice can actually improve.
Notice where the leverage sits. Improve the close rate from 50% to 60% and the chain needs 30 consults, 50 leads, and $7,500 — the same $60,000 goal for $1,500 less per month. That improvement usually comes from front-desk conversion, which costs far less than buying more leads.
The inputs that move your number most
Close rate — the cheapest lever in the building. Of all five inputs, this is the one owners control most and measure least. A ten-point swing in consult-to-start rate changes the required budget by roughly a fifth. Before raising spend, verify this number with 90 days of real data.
Case mix. Blending implant production with hygiene exams into one "average case value" distorts the chain. If your goal is weighted toward implants, run the math on the implant funnel separately — higher cost per lead, but far fewer cases needed to hit the same revenue.
Channel economics. Cost per lead is not one number. Paid search in competitive Houston suburbs costs more than it did three years ago; organic and referral leads cost less but arrive slower. The calculator's range reflects that spread — practices leaning on paid search land near the top, practices with strong organic and referral bases near the bottom.
Common budgeting mistakes we see
- Budgeting a percentage without checking the chain. 5% of revenue is a planning habit, not a plan. Run the chain; if the percentage and the chain disagree, trust the chain.
- Mixing new-patient goals with recall revenue. The goal at the top must be production from new patients — the only production marketing can create. Counting hygiene recall inflates the goal and the budget.
- Blending case values across wildly different services. One average for exams, crowns, implants, and ortho is three different budgets wearing a trench coat. Segment when the mix is lopsided.
- Forgetting capacity. The example above needs 36 consults a month — roughly nine a week. If the schedule and the front desk can't absorb them, the bottleneck isn't budget, it's capacity. Run the growth diagnostic to find out which problem you actually have.
- Treating the output as a quote. This is planning math, not a proposal. Your actual lead economics depend on suburb, competition, and case mix.
How to use your number
Treat the calculator's range as a planning boundary, not a purchase order. Start with your best estimates, measure the real inputs for 90 days — especially close rate and lead-to-consult conversion — and let the number tighten itself. When the range moves, you'll know whether it's because your marketing got better or because you finally measured honestly.
And if the number surprises you, that's the point. A budget derived from your goal, your case value, and your close rate is a budget you can defend — to a partner, a spouse, or yourself.
