How do you calculate dental marketing ROI?

Enter monthly marketing spend, qualified leads, lead-to-new-patient conversion rate, first-year collections per new patient, and contribution margin. The calculator estimates new-patient contribution, subtracts marketing spend, then expresses the net as ROI.

What is dental patient acquisition cost?

Patient acquisition cost is monthly marketing spend divided by the estimated number of new patients from the campaign. The result is only useful if the lead and new-patient counts are attributed consistently.

Why use contribution margin instead of collections?

Collections are not profit. Contribution margin adjusts the first-year collection value for variable costs, so the ROI estimate is closer to the dollars available after campaign-linked costs.

Marketing inputs

Translate campaign spend, lead volume, conversion rate, and first-year patient value into CAC, break-even volume, and contribution after marketing.

Monthly marketing spend

Ad spend, agency fees, creative, landing pages, call tracking, and campaign software.

$4,000

Monthly leads

Qualified calls, forms, chats, and booking requests attributable to the campaign.

Lead-to-new-patient rate

The share of leads that become kept new-patient appointments.

25%

First-year collections per new patient

Average collected production from a new patient in the first year.

$1,200

Contribution margin

Collections left after variable costs such as lab, supplies, and provider pay.

55%

Net monthly contribution

$9,200

This assumes 20 new patients a month, $200 CAC, and 230% ROI after the marketing spend.

Cost per lead

before lead quality adjustment

Break-even patients

6.1

new patients per month

New-patient collections: $24,000 per month

Contribution before marketing: $13,200

One more lead is worth about $165 in expected contribution at this conversion rate.

Annualized net contribution: $110,400

How the ROI is calculated

The calculator starts with campaign spend and lead volume to estimate cost per lead. It then applies your lead-to-new-patient rate to estimate patient acquisition cost, first-year collections, contribution before marketing, and net contribution after marketing spend.

The break-even result answers a practical question: how many new patients would this campaign need to cover its own spend at the entered patient value and contribution margin? The lead break-even converts that patient target back into a lead target using your conversion rate.

Use it before scaling spend

- Compare paid search, local SEO, social ads, referral campaigns, and mailers on the same unit-economics basis.
- Separate low-cost leads from campaigns that actually produce kept new-patient appointments.
- Pair the result with the production-goal calculator before adding demand the schedule cannot absorb.
- Re-run the model with actual call tracking, booking, show-rate, and collection data after each campaign cycle.
