Optometry Practice Overhead: Benchmarks and a Budget That Fits on One Page

Optometry practice overhead rarely explodes; it creeps. A software subscription here, an extra staff hour there, a lab invoice nobody reconciles — and three years later a practice grossing more than ever is taking home less. The defense isn't heroic cost-cutting; it's category benchmarks, a one-page budget, and a monthly fifteen-minute variance habit.

The benchmark map

Expressed as percentages of gross collected revenue, well-run independent optometry practices tend to land near: staffing (non-OD) 18–22% — the largest and most watched line; cost of goods 25–30% — frames, lenses, lab, contacts (dispensary-heavy practices run higher with the revenue to justify it — see our COGS deep-dive); occupancy 5–8%; marketing 2–5% depending on growth phase; equipment and technology 3–5% including EHR and device service contracts; everything else (insurance, fees, supplies, CE) 6–10%. Total overhead before OD compensation typically lands between 60% and 70%. Your numbers will differ — the point is knowing yours and watching the trend, not hitting someone else's decimal.

Build the one-page budget

Take twelve months of P&L, sort every expense into the seven categories above, and set next year's target per category as a revenue percentage. That's the whole budget. Sophistication is the enemy here — a 40-line budget gets abandoned by March; a 7-line budget gets checked monthly for a decade. Add one capital line for planned equipment so a new OCT is a decision, not a surprise.

The monthly variance habit

Fifteen minutes, same day each month: actual percentage versus target per category, with a one-sentence note on anything off by more than a point. The note is the discipline — 'staffing up 1.5%: overtime covering front-desk vacancy' is actionable; a red cell is not. Two categories drifting for two consecutive months triggers a real conversation. This is also where the fixes live: staffing drift usually means overtime and task overflow (often solved cheaper by routing administrative load to an eye care virtual assistant at a flat $10/hour than by adding local payroll); COGS drift means lab-invoice reconciliation and inventory discipline; technology drift means the annual subscription audit nobody enjoys and everybody profits from.

Protect the two spends that earn

Budget discipline fails when it cuts muscle with fat. Two categories deserve protection even in tight years: the marketing that demonstrably fills chairs (measure it — our local SEO guide is the cheapest chair-filler in eye care), and the staff hours that generate revenue — pretesting, optical, recall. The goal is not minimum overhead; it's maximum margin, which sometimes means spending more where the return is proven. Ophthalmology groups run this same budget architecture with bigger numbers; the discipline scales in both directions.

The assembly problem

None of this is hard — it's just monthly, and 'monthly' is where practice owners quietly fail. Categorizing the P&L, building the variance sheet, chasing the anomalies, reconciling lab invoices: that's the bookkeeping-adjacent layer a trained virtual assistant maintains so the owner's fifteen minutes stay fifteen minutes. Budgets don't manage practices; rhythms do.
