A practice is bought for its client list. These are bought for what they can produce — and every one of them has a hard limit on that. Technician hours, covers, machine hours. Growth past the ceiling needs capital, not effort.

Which is why a buyer works out where the ceiling is before they work out what the earnings are worth.

Three operating businesses

Each models the constraint that actually binds in its sector, then prices the earnings against it. They share the same spine as the practice calculators — profile, five-year history, earnings normalization, projections, valuation and adviser notes — so learning one carries across.

Ceiling · Technician hours

Service agreements as recurring revenue, replacement work as lumpy revenue. The two are priced differently and a buyer separates them before anything else.

Ceiling · Covers and seat turns

Prime cost against the sixty-five line, and the paradox that hiring a manager cuts earnings while raising the price a buyer will pay.

Manufacturing12 tabs

Ceiling · Machine hours

Capacity is a ceiling, working capital ties up a quarter of revenue, and half the balance sheet is equipment a lender will lend against.

What makes these different

Four things a practice barely has, and all four move the price.

Capacity is a ceiling, not a target

Every one of these models the ceiling explicitly. A business at 95% utilization has no growth left to sell without capital, and that is a different story from one at 60%.

Equipment is collateral, not just cost

Orderly liquidation value decides how much of the price a lender will fund. It is the difference between a deal that closes and one that does not.

Working capital moves the price

Manufacturing ties up cash in inventory and receivables. A restaurant is funded by its suppliers. Both are negotiated at close, and both surprise sellers.

The owner is usually working in it

So SDE and normalized EBITDA both matter, and they differ by exactly a market wage. Every calculator here keeps the two apart and says which one it is pricing.

The tools that go with them

Equipment-heavy businesses are financed differently, and the financing decides what a buyer can pay.
