New Patient Value & Marketing ROI

Marketing a dental practice costs money, and it can be hard to tell whether it pays off. The key is knowing what a new patient is worth over time. This calculator estimates the lifetime value of a new patient, your marketing cost per new patient, and the return on what you spend.

What this calculator does

Enter what a new patient typically brings in during their first year, what a returning patient brings in each later year, the percentage of patients who stay each year, how many years to count, and your profit margin on that care. Then enter your monthly marketing spend and the new patients it brings in. The calculator shows:

• the lifetime profit per new patient,
• lifetime collections per new patient,
• your marketing cost per new patient,
• your marketing return, and
• the most you could pay per new patient and still break even.

The formula in plain English

Lifetime collections = first-year collections + returning collections × (retention + retention² + … for each later year).

For example, with 70% retention, a patient's second year counts at 70%, the third at 49%, and so on, because some patients leave each year.

Lifetime profit = lifetime collections × profit margin.

Cost per new patient = monthly marketing spend ÷ new patients per month.

Marketing return = (lifetime profit × new patients − marketing spend) ÷ marketing spend.

Break-even cost per patient = lifetime profit per patient.

A worked example

Dr. Hughes finds that a new patient brings in about $950 in their first year, including exams, cleanings and initial treatment, and $550 each year after. About 70% of patients return each year. She counts five years and estimates a 40% profit margin.

• Lifetime collections: about $1,925 per patient.
• Lifetime profit: about $770.
• She spends $3,500 a month on marketing and gets 14 new patients from it.
• Cost per new patient: $250.
• Marketing return: about 208%. Each dollar of marketing brings back about $3.08 in profit over five years.

She could pay up to about $770 per new patient and still break even. If one channel costs $600 per patient and another costs $150, she knows where to put more money.

Why it matters at each career stage

If you're: Practice owner

Track new patients by source every month: ask "How did you hear about us?" at check-in, use call tracking for ads and keep referral records. Then run this for each channel to see which ones are worth growing.

If you're: Employed

Thinking about buying or starting a practice? Knowing patient value helps you judge how fast a startup can grow and what an existing patient base is really worth.

Raising patient value

Retention matters most. Raising retention from 70% to 80% adds far more value than a small fee increase. Pre-appoint recall visits and follow up with patients who miss them.

Present treatment clearly. Patients who understand their options and costs are more likely to accept care.

Make it easy to pay. Payment plans and membership plans keep patients who might otherwise delay care.

Ask for reviews and referrals. Satisfied patients bring in more patients at almost no cost.

A note on first-year value

New patients often bring in more in their first year because they come in with treatment needs that have built up. Use real numbers from your own practice, if you can, by looking at a group of new patients from a past year and adding up what they spent in their first year and after.
