You might be wondering how the ROI calculator works. Well, math nerd, here you go. 😆
How the ROI Math Works
The calculator uses three simple relationships to estimate your marketing return potential:
Marketing Investment
This shows how much money your practice is putting toward marketing each year.
Example: if your revenue is $1,000,000 and you invest 10%, your annual marketing investment is $100,000.
Break-Even Point (Patients Needed)
This tells you how many new patients are needed for the revenue they generate to equal your marketing cost.
Example: if your investment is $45,000 and your LTV is $3,000, you need
45,000 ÷ 3,000 = 15 new patients to break even.
(The calculator rounds this number up to the nearest whole patient.)
Monthly Plans
To help with goal-setting, the calculator divides that break-even total across different timeframes:
3-Month Plan: total ÷ 3
6-Month Plan: total ÷ 6
12-Month Plan: total ÷ 12
This shows how many new patients per month you’d need to hit break-even in each period.
Summary of Logic
You choose how much to invest (as a % of revenue).
The calculator divides that investment by your average patient value.
The result is the number of new patients required to recover your marketing spend — everything beyond that point is profit.
