Reducing Dental Office Overhead: The 15 Line Items to Attack First

Overhead is not a cost of doing business. It is the game. Win it and you buy back your time, your freedom, and your exit. Lose it and you produce a fortune and keep almost none of it. On the Bulletproof Dental Practice Podcast, Pete Boulden sat across from a dentist who ran a fee-for-service practice at 43% overhead — working two and a half days a week, saving north of 20% of his income for 23 straight years, and retiring at 58. Pete’s honest confession in that same episode? He was sitting at 60.1% and grinding to break into the fifties. That gap is the whole ballgame.

This is not a “trim the coffee budget” article. This is the 15 line items to attack, in order, and the mindset that separates the 1% of owners who keep their money from the 99% who don’t.

Why is dental office overhead the number that actually decides your freedom?

Here is the tactical truth Pete hammers constantly: it is not about how much you produce, it is about how much you keep. Two doctors can each collect $1.2M. One runs at 55% overhead and takes home $540K. The other runs at 70% and takes home $360K. Same chairs, same hours, same stress — a $180,000 difference that shows up every single year and compounds for a career.

Fat margins are not vanity. They are armor. Strong hygiene, strong case acceptance, and lean overhead mean you never need a rescue when a recession hits, when a key associate leaves, or when a PPO cuts your reimbursement. Profit is what makes a practice recession-proof.

What overhead percentage should a dental practice actually run at?

The published “average” hovers around 60-65% for a general practice — which is exactly why average dentists feel broke on paper-rich production. Here are the anchors we talk about on the show:

• 60%+ overhead: the danger zone. You are working for your vendors, your landlord, and your payroll — not your family.
• Low-to-mid 50s: a healthy, well-run insurance-mixed practice. This is a realistic, aggressive target for most owners.
• Mid-40s: elite. Our fee-for-service guest hit 43% for the majority of a 30-year career — and he was blunt that low overhead started on day one, not as a rescue project at year 20.

The lesson: you do not stumble into low overhead. You engineer it, and you watch the numbers relentlessly. As our guest put it, the overhead game “was the Holy Grail… the game I wanted to win, and I played it to win.”

Which 15 line items should you attack first?

Overhead lives in a handful of buckets. Attack them in this order — biggest, most fixable dollars first.

1. Team payroll (usually your #1 cost). Target roughly 25-28% of collections for staff wages (doctor comp separate). The fix is not firing good people — it’s productivity per payroll dollar. An overstaffed slow schedule is the silent killer.
2. Dental supplies. The published benchmark is ~5-6% of collections. Our low-overhead guest ran 3.21% — and not even through a buying group, just disciplined ordering and vendor pressure. If you’re above 6%, there is real money here.
3. Lab bills. Target 5-8% depending on your case mix. Same-day dentistry (CEREC), in-house milling, and negotiated lab pricing move this number fast.
4. Rent / occupancy. Should sit around 5-7% of collections. Our guest named low rent as a core pillar of his 43%. If you signed a lease at the top of the market, renegotiate at renewal or buy the building.
5. Insurance write-offs (the invisible overhead). PPO adjustments don’t show up as an “expense” line but they gut your margin. Our guest steadily dropped plans that stopped keeping pace with fee increases. Audit every plan’s true reimbursement.
6. Merchant / credit card fees. 2-4% of every dollar. Shop processors and pass through where legal.
7. Marketing spend. Not to cut — to make efficient. Measure cost per new patient by channel and kill what doesn’t convert.
8. Software & tech stack subscriptions. Audit every recurring SaaS charge. Practices routinely pay for 3 tools that do one job.
9. Office supplies & shipping. Small individually, death by a thousand cuts collectively.
10. Continuing education & travel. Keep it — but tie it to ROI, not just tax write-offs.
11. Repairs & equipment service contracts. Renegotiate or self-insure the small stuff.
12. Utilities & phone/internet. Re-shop annually; providers bank on your inertia.
13. Professional fees (legal/accounting). Worth paying for — but scope them and avoid surprise hourly bloat.
14. Interest on debt. Refinance high-rate practice debt; every point saved is pure margin.
15. Waste, breakage & shrinkage. Expired materials, over-ordering, un-tracked inventory. A simple par-level system pays for itself.

How do you cut overhead without wrecking your culture?

This is where Craig Spodak’s voice matters as much as the spreadsheet. Cutting overhead the wrong way — slashing pay, nickel-and-diming your team, killing the perks that make people stay — will cost you far more than it saves. Turnover is the most expensive line item that never appears on your P&L.

Craig’s frame: you are not cutting costs, you are eliminating waste so you can invest in the things that actually build a practice people never want to leave. Lean overhead should fund a great team, not starve one. When your team understands that a healthy margin is what pays for their bonuses, their growth, and the practice’s stability, they become your allies in the overhead game — not its casualties.

The dentists who win this game don’t do it alone, and they don’t do it by being cheap. They do it by watching the numbers weekly, benchmarking against peers who are further ahead, and refusing to accept “average” as their ceiling. That is exactly the room we’ve built inside the Bulletproof Mastermind — owners who put their real P&Ls on the table and push each other toward the fifties, the forties, and freedom.

Where do you start this week?

• Pull your last 12 months and calculate overhead as a true percentage of collections.
• Break it into the 15 buckets above and flag every one that’s above benchmark.
• Attack the three biggest gaps first — usually payroll efficiency, supplies, and PPO write-offs.
• Set a target (start with “under 55%”) and review it every single month.

Dentistry is a lonely profession when you’re staring at a P&L alone at 9pm wondering where the money went. It doesn’t have to be.
