📊 Financial Modeling

Know your numbers.
Build a practice that pays you.

Most therapists undercharge, overwork, and never model their finances until something goes wrong. These free interactive calculators — plus a curated directory of financial tools — change that in minutes, not months.

💡 Financial Reality for Therapists
These calculators use gross revenue as the starting point. Remember to account for self-employment tax (~15.3%) and federal/state income tax when planning your net take-home. A common rule of thumb: set aside 30–35% of gross for taxes if you're self-employed in the US. Consider working with a CPA who understands private practice.
Curated Tools

The best financial tools
for private practice

Third-party platforms reviewed and recommended for therapists — with notes on how each applies to your specific practice structure.

📒
QuickBooks Self-Employed
Bookkeeping & Tax
Tracks income and expenses, separates personal from business transactions, estimates quarterly taxes, and exports a Schedule C-ready summary. The gold standard for solo practice bookkeeping.
Therapist tip: Use the mileage tracker if you drive to supervision, trainings, or off-site sessions. It's often the most overlooked deduction in private practice.

🌊
Wave Accounting
Bookkeeping — Free
Completely free invoicing, expense tracking, and income reports. Ideal for therapists just starting out or those who see a limited number of private-pay clients alongside insurance.
Therapist tip: Wave is especially useful for therapists who offer coaching or consulting alongside therapy — they can invoice separately for each service line.

🏥
SimplePractice Reports
Practice Management Finance
If you're already on SimplePractice, you have a surprisingly powerful financial reporting suite built in — most therapists never use it. Track revenue by payer, session type, and time period.
Therapist tip: Run the "Outstanding Balances" report monthly. Uncollected copays and billing errors are often the single biggest source of revenue leakage in private practice.

🏦
Relay Business Banking
Business Banking
Online business bank account with no monthly fees, built-in profit-first budgeting tools, and multiple sub-accounts (taxes, expenses, profit). Therapists love the simplicity and the Profit First compatibility.
Therapist tip: Open separate sub-accounts for Taxes (set to 30%), Operating Expenses, and Owner Pay. This one habit eliminates most year-end financial stress for solo practitioners.

Monarch Money
Personal + Business Finance
Tracks both personal and business cash flow in one place — ideal for therapists who run as sole proprietors and need a unified view of their finances to understand true net income.
Therapist tip: Use the net worth tracker to see how your practice is building long-term financial security — not just month-to-month income. Pairs well with SEP-IRA and solo 401(k) planning.

🤖
TaxBuddy for Therapists
Tax Estimation (AI)
AI-powered quarterly tax estimator built specifically for self-employed therapists — accounts for SE tax, deductions common to private practice (CEUs, supervision, home office), and state obligations.
Therapist tip: Run this every quarter before your estimated payment deadlines (April 15, June 15, Sept 15, Jan 15). Underpayment penalties are easily avoided with a reliable estimate.
