Rough reserve helper

A rough cushion: a monthly cash budget multiplied by a number of months. It is not a forecast of working capital, a receivables model, or an indication of what a lender would fund. It changes the reserve field only when you click the button, and it never alters the operating-cost model.

Downside and alternative-rate scenarios. Fixed costs and owner-work compensation are held constant while variable costs scale with collections, which is what makes a collections shortfall land almost entirely on ownership cash.

What moves this model

  • Because fixed costs and owner-work compensation do not move with collections, a 10% collections shortfall removes much more than 10% of ownership cash. That asymmetry, not the headline number, is usually the useful output of this model.
  • The working-capital reserve is funded once at closing. Whether it is enough depends on how long collections take to arrive after the transition, which this model does not attempt to predict.
  • Nothing here is a lending decision, a credit approval, a prequalification or a projection of your results. Coverage ratios are illustrative: every lender defines and tests coverage its own way, using its own adjustments and thresholds.
  • Transition risk, patient retention, payer mix, provider and hygiene capacity, lease terms, equipment condition and working-capital timing all affect the outcome and none of them are modeled here.

How this calculator works

total_uses = purchase_price + transaction_expenses + initial_capital + initial_reserve
buyer_cash_required = total_uses - proposed_acquisition_loan
cash_before_debt = collections*(1 - variable_cost_share)
  - fixed_operating_costs - owner_work_compensation - maintenance_capital
annual_debt_service = new_loan_scheduled_payments_in_year_one + retained_business_debt_service
illustrative_coverage = cash_before_debt / annual_debt_service
ownership_cash_after_debt = cash_before_debt - annual_debt_service
cash_on_cash = ownership_cash_after_debt / buyer_cash_required

Owner pay is pay, not profit

Market compensation for the clinical and management work is deducted before ownership cash, and it is never added back into the coverage figure. If you do that work, that money is compensation for your labour. What is left after it, and after debt service, is what ownership itself produced. A model that treats owner pay as profit will make almost any practice look like it works.

The coverage ratio here is not a lender's DSCR

This coverage figure divides cash before debt service (already reduced by owner replacement pay and by maintenance capital) by annual debt service. That is deliberately more conservative than most lender formulas, which commonly add back some owner compensation and ignore maintenance capital. It is an illustration, not any particular lender's calculation and not an approval threshold. When there is no debt, coverage is reported as not applicable rather than as an infinite ratio.

Principal paydown is not spendable cash

The principal repaid in year one is shown separately from ownership cash because it is not money you can spend: it converts cash into a smaller loan balance. It is also not guaranteed wealth creation. If the practice is worth less in three years than it is today, a smaller loan balance can be entirely offset by a lower business value.

How the scenarios move

  • The collections downside cases hold fixed operating costs, owner-work compensation and maintenance capital constant, and scale variable costs with collections. That is the point: a revenue shortfall lands almost entirely on ownership cash.
  • The rate stress case is an alternative loan assumption, what the same purchase looks like if the financing is priced two percentage points higher. It is not a forecast that a fixed rate resets.
  • The purchase-price slider changes total uses and buyer cash while holding the loan you entered constant. It does not quietly raise the assumed advance to preserve a down payment percentage, because a lender's advance is a lender's decision.
  • Changing the proposed borrowing changes buyer cash and debt service. It does not change the practice's operating earnings.

What is excluded

  • Income taxes of any kind, at the entity or the personal level.
  • Personal debt, personal living costs and the global cash flow a lender will actually examine.
  • Receivables and payables timing. This is an annual cash model, not a month-by-month working capital forecast.
  • Changes in staffing needs, associate arrangements or hours as the practice changes hands.
  • Any cost you did not enter. The model is arithmetic on your assumptions and does not reconcile a complete set of accounts.
  • Real estate. The property is handled in the linked property tools rather than folded into practice value here.

Nothing here is a maximum approved purchase price, a statement of lender eligibility, or a recommendation to buy or not buy a practice.

Questions to ask during diligence and with a lender

  • Which expenses in the seller's accounts will actually change under your ownership, and by how much?
  • What is the real cost to replace the seller's production, whether by your own time or an associate?
  • What working capital does the practice need at closing, and who collects the pre-closing receivables?
  • What does the lender include and exclude in its own cash-flow test, and what coverage does it require?
  • What personal guarantee, collateral and global cash-flow review apply?
  • What conditions remain before funding, and how long will they take?
