Planning estimate only; not marketing, accounting, tax, valuation, lending, legal, or financial advice. Attribute leads, new patients, collections, and campaign spend consistently before using the result for budget decisions.

## Direct answer

- Cost per lead = monthly marketing spend / monthly leads.
- Patient acquisition cost = monthly marketing spend / estimated new patients.
- Estimated new patients = monthly leads x lead-to-new-patient conversion rate.
- Net marketing contribution = new-patient collections x contribution margin - marketing spend.
- Default example: $4,000 spend, 80 leads, 25% conversion, $1,200 first-year collections, and 55% margin create about $9,200 in net monthly contribution after marketing.
- The default patient acquisition cost is about $200, with a break-even point of 6.1 new patients per month.

## Inputs

- Monthly marketing spend
- Monthly leads
- Lead-to-new-patient conversion rate
- First-year collections per new patient
- Contribution margin

## Source basis

- Dentovio arithmetic model using user-entered campaign spend, lead count, conversion rate, first-year collection value, and contribution margin. No market benchmark is implied.
