02 · How the maths works

The formula, written out.

Attributed patients are your tracked leads for the year multiplied by the share of them that become patients. Attributed gross profit is those patients multiplied by first-year collected revenue, multiplied by your gross margin.

Marketing ROI is gross profit minus marketing cost, divided by marketing cost. Break-even is the number of patients whose gross profit covers the year of spend.

Use collected revenue, not treatment plan value. Deduplicate the leads. Use the same date range for cost and outcome, or the answer means nothing.

03 · What it cannot tell you

This is an estimate, not a forecast.

It leaves out lifetime value, referrals from those patients, chair capacity, collection delays, and every attribution error in your tracking. It is not a practice valuation and it does not predict next year.

Check the output against your accounting records, your practice management reports, and your call and form tracking before you make a decision with it.

We publish results only with a baseline, a date range, and the client’s approval.
