The Reverse-Engineering Your Practice Worksheet
Calculate exactly how much your practice must earn to fund your ideal life
Most practice owners work the equation backwards: they earn what they earn, then try to live on whatever remains. The Reverse-Engineering framework flips this by starting with your desired personal lifestyle, then calculating exactly what your practice needs to generate to support it.
The framework uses two worksheets. First, the Lifestyle Worksheet catalogues your actual monthly personal expenses across all categories (housing, food, transportation, etc.) in two columns: Current spending and Nice-to-Have spending. Second, the Reverse-Engineering Worksheet uses three levers (average fee per session, number of sessions, and Owner's Pay allocation percentage) to calculate the monthly revenue and session count required.
By adjusting these three levers, you can model different scenarios: raising your rates, increasing sessions, growing to a group practice, or adjusting allocations. This transforms vague financial anxiety into concrete, actionable numbers.
- Your business must serve your life, not the other way around
- Start with what you need personally, then engineer the business to deliver it
- Three levers control your income: session rate, session count, and Owner's Pay allocation
- Financial success is rarely about luck; 93% of millionaires accumulated wealth through working and saving, not high salaries
- Complete the Lifestyle WorksheetList all monthly personal expenses across categories like housing, food, transportation, insurance, debt payments, savings, and discretionary spending. Fill in both Current amounts and Nice-to-Have dream amounts.
- Enter Your Desired Take-Home PayUse the total from your Lifestyle Worksheet Current column as your starting desired monthly take-home pay. This becomes Row 1 of the Reverse-Engineering Worksheet.
- Calculate Required Monthly RevenueDivide your desired take-home pay by your Owner's Pay allocation percentage. For example, $7,000 divided by 48% equals $14,583 required monthly revenue. This tells you exactly what your practice needs to generate.Pro tipRun this calculation multiple times, pulling different levers. Try higher rates, more sessions, or different allocation percentages to see how each changes the picture.
- Calculate Required Monthly SessionsDivide the required monthly revenue by your average fee per session. This gives you the concrete session count your practice needs each month to fund your lifestyle.Pro tipTry this exercise with your Nice-to-Have lifestyle numbers and with group practice TAPs to see what growing your practice could enable.WarningIf the required session count exceeds what's realistic for your practice size, you've identified a structural gap that needs to be addressed through rate increases, hiring, or personal expense reduction.
Brent had been taking 'whatever was left' from his business, spending emotionally rather than strategically. His haphazard system meant slow months and tax time were always stressful. After completing the reverse-engineering exercise, he calculated he needed two additional full-time clinicians to generate his desired Owner's Pay.
A solo practice owner needing $7,000/month with a 48% Owner's Pay allocation at $125/session needs 117 sessions monthly. By raising the rate to $175/session, the required sessions drop to 84 per month, a significant reduction in workload.
Julie Herres observed that too many practice owners treated their take-home pay as an afterthought, taking whatever was left after all business expenses were covered. This led to chronic underpayment, personal debt, and burnout. By creating a simple mathematical framework that starts with personal needs and works backwards to business requirements, she gave practice owners a tool to make their business serve them rather than the other way around.
