Your Overhead Is 62%. Here's Exactly Where You're Bleeding
You collected $1.2M last year. Your accountant says you netted $380K. That's a 68% overhead rate - and you have no idea where it all went.
You're not alone. Most practice owners can't break down their overhead beyond "staff is expensive" and "supplies keep going up." Meanwhile, you're bleeding cash in six different categories, and half of them are fixable.
Let's run the real numbers.
The Overhead Breakdown: Where Every Dollar Goes
Industry benchmarks put healthy overhead at 55-65% for general practices. Specialists run leaner (45-55%). DSOs target 60-70% because they're optimizing for growth, not margins.
If you're above 70%, you're in trouble. Below 50%? You're either very efficient or not investing enough in growth.
Here's the category-by-category breakdown for a typical $1.5M general practice:
Staff Costs: 25-28% of Collections
This is your biggest line item. For a $1.5M practice, that's $375K-420K annually.
Typical team for this production level:
- 2 hygienists: $80K-100K each ($160K-200K total)
- 2-3 dental assistants: $40K-50K each ($120K-150K total)
- 1-2 front desk: $35K-45K each ($70K-90K total)
- Office manager: $55K-70K
- Payroll taxes and benefits: Add 15-20% on top of salaries
If your staff costs are pushing 30-32%, you're either overstaffed or overpaying for your production level. If you're under 22%, you're probably understaffed and leaving production on the table.
Where practices bleed:
- Paying hygienists $50/hour when production doesn't support it
- Overstaffing front desk (two people doing one person's job)
- Overtime because you won't hire another assistant
- High turnover driving constant recruiting and training costs
Facility Costs: 5-8% of Collections
Rent or mortgage, utilities, maintenance, property insurance. For a $1.5M practice, that's $75K-120K/year.
If you're leasing: $4K-8K/month is typical for 1,500-2,500 sq ft in a decent location. Buying is usually cheaper long-term but ties up capital.
If you're over 10%, you either built a palace or you're in a wildly expensive market (Manhattan, San Francisco). Renegotiate or relocate.
Where practices bleed:
- Signing long leases at top-of-market rates without negotiation
- Overbuilding (3,000 sq ft for a solo practice)
- Deferred maintenance creating expensive emergency repairs
- Inefficient HVAC and lighting (old buildings kill you on utilities)
Supplies: 5-7% of Collections
Clinical and office supplies. For $1.5M, that's $75K-105K/year.
Breakdown:
- Disposables: Gloves, bibs, barriers, suction tips ($15K-25K)
- Restorative materials: Composites, cements, bonding agents ($20K-30K)
- Anesthetics and medications: $8K-12K
- Office supplies: Paper, printing, postage ($5K-8K)
- Sterilization supplies: Pouches, indicators, enzymatic ($3K-5K)
If you're over 8%, you're either doing a lot of implants/specialty work (higher material costs) or you're getting ripped off by vendors.
Where practices bleed:
- Paying list price instead of negotiating with suppliers
- Not using GPOs (group purchasing organizations) for volume discounts
- Staff wasting supplies (opening suture packs they don't need)
- Buying brand-name when generic is clinically identical
Lab Fees: 8-12% of Collections
Crowns, bridges, dentures, ortho appliances. For $1.5M, that's $120K-180K/year.
Typical costs:
- PFM crown: $80-120 per unit
- All-ceramic crown: $100-150 per unit
- Implant crown: $120-180 per unit
- Bridge (3-unit): $250-400
- Full denture: $150-300
If you're over 14%, you're either doing heavy crown/bridge work or using premium labs when mid-tier would be fine. If you're under 6%, you're probably not doing enough restorative (leaving money on the table).
Where practices bleed:
- Using the same lab for everything instead of tiering (premium lab for anterior esthetics, value lab for posteriors)
- Remakes due to poor impressions or communication
- Rush fees because you didn't plan ahead
- Not negotiating volume discounts with your primary lab
Marketing: 2-5% of Collections
Patient acquisition and retention. For $1.5M, that's $30K-75K/year.
Typical spend:
- Website and SEO: $500-1,500/month ($6K-18K/year)
- Google Ads: $1K-3K/month ($12K-36K/year)
- Direct mail: $5K-15K/year
- Patient reactivation: $2K-5K/year
- Social media: $3K-8K/year
If you're spending under 2%, you're invisible. Over 7%, you're either in hyper-growth mode or wasting money on channels that don't convert.
Where practices bleed:
- Google Ads without conversion tracking (no idea what's working)
- Paying $2K/month for "dental marketing" that's just Facebook posts
- Yellow Pages ads in 2026 (yes, this still happens)
- Not tracking cost-per-new-patient by channel
Equipment and Technology: 3-6% of Collections
Purchases, leases, maintenance, software. For $1.5M, that's $45K-90K/year.
This includes:
- Practice management software: $500-1,000/month ($6K-12K/year)
- Equipment leases: $1K-3K/month ($12K-36K/year)
- Equipment maintenance: $500-1,000/month ($6K-12K/year)
- New equipment purchases: Amortized over useful life
- IT and phones: $300-600/month ($4K-7K/year)
If you're over 8%, you're either growing aggressively (new chairs, CBCT, etc.) or financing everything instead of buying used/refurbished.
Where practices bleed:
- Leasing equipment at 12-18% interest when you could buy cash
- Buying every new gadget that reps pitch ("this laser will change your practice!")
- Not maintaining equipment (leading to expensive replacements)
- Overpaying for software that you use 20% of the features
Administrative and Professional Fees: 5-8% of Collections
Accounting, legal, insurance, licenses, continuing ed, memberships. For $1.5M, that's $75K-120K/year.
Breakdown:
- Malpractice insurance: $3K-8K/year per provider
- General liability and property insurance: $5K-10K/year
- Accounting and bookkeeping: $500-1,500/month ($6K-18K/year)
- Legal fees: $2K-5K/year (more if you have disputes)
- Licenses and memberships: $2K-4K/year
- Continuing education: $3K-6K/year per provider
- Payroll processing: $100-300/month ($1.2K-3.6K/year)
Where practices bleed:
- Using full-service bookkeepers when software could handle 80% of it
- Not shopping malpractice insurance annually
- Paying CPA $5K to do what TurboTax could do
- Expensive CE courses that don't drive revenue
OPERATOR MATH: Solo Practice vs Group vs DSO
Overhead structure varies wildly by practice model. Here's what it looks like for three $1.5M practices with different structures:
Solo Practice (1 owner-dentist, producing $1.5M)
Collections: $1,500,000
Overhead breakdown:
- Staff (4 FTEs): $360,000 (24%)
- Facility: $90,000 (6%)
- Supplies: $90,000 (6%)
- Lab: $150,000 (10%)
- Marketing: $45,000 (3%)
- Equipment/Tech: $60,000 (4%)
- Admin/Professional: $105,000 (7%)
Total overhead: $900,000 (60%)
Owner take-home: $600,000 (40%)
This is efficient. Solo docs have lower staff costs (no associate salaries) and tighter control. But they're maxed out on production - limited by their own chair time.
Group Practice (1 owner + 2 associates, producing $1.5M)
Collections: $1,500,000
Overhead breakdown:
- Staff (6 FTEs + 2 associates): $630,000 (42%)
- Facility: $105,000 (7%)
- Supplies: $105,000 (7%)
- Lab: $165,000 (11%)
- Marketing: $60,000 (4%)
- Equipment/Tech: $75,000 (5%)
- Admin/Professional: $120,000 (8%)
Total overhead: $1,260,000 (84%)
Owner take-home: $240,000 (16%)
Wait - the owner made less than the solo doc despite same revenue? Yes. Associates eat margin. But the owner also worked fewer clinical hours and has scalability. If they grow to $3M, margins improve dramatically.
DSO-Affiliated Practice (Corporate ownership, $1.5M production)
Collections: $1,500,000
Overhead breakdown:
- Staff: $420,000 (28%)
- Facility: $120,000 (8%)
- Supplies: $90,000 (6%)
- Lab: $135,000 (9%)
- Marketing: $75,000 (5%)
- Equipment/Tech: $90,000 (6%)
- Admin/Professional: $60,000 (4%)
- DSO management fee: $210,000 (14%)
Total overhead: $1,200,000 (80%)
Practice EBITDA: $300,000 (20%)
DSOs run higher overhead but have centralized efficiencies (bulk purchasing, shared admin, marketing scale). The 14% management fee covers corporate overhead, technology, and growth investment.
Where You're Actually Bleeding (The Fixable Stuff)
Most overhead isn't waste. It's the cost of running a practice. But there are categories where you're likely bleeding unnecessarily.
Overstaffing Front Desk
Do you need two front desk people? In most practices under $2M, the answer is no. One competent person with good software can handle scheduling, insurance, and billing for 1,500-2,000 active patients.
If you have two front desk staff and they're not slammed, you're overstaffed. That's $40K-50K you're bleeding annually.
Fix: Consolidate to one front desk + part-time backup. Invest in better software (online scheduling, automated reminders) to reduce manual work.
Premium Supplies When Generic Works Fine
Are you using brand-name composite for every Class II? Paying $180 for premium gloves when $60 nitrile gloves are clinically equivalent?
Supplies creep up when you're not paying attention. Reps convince you their premium product is "better," but usually the mid-tier option performs identically.
Fix: Audit your supply spend quarterly. Switch to generics for non-critical items. Negotiate with suppliers - they'll discount 10-20% if you commit to volume.
Marketing Spend with No ROI Tracking
You're spending $5K/month on marketing. How many new patients did it bring in? What's your cost per acquisition by channel?
If you don't know, you're flying blind. Half your marketing budget is probably wasted.
Fix: Track new patient source for every patient. Ask "How did you find us?" at every new patient appointment. Run the math monthly: $X spent on Google Ads, Y new patients, cost per new patient = $X/Y. Kill channels with cost-per-patient over $300-400.
Equipment Leases at Predatory Rates
That CBCT you leased at 14% interest? You'll pay $180K over 7 years for a $90K machine. You just doubled the cost.
Dental equipment financing is often a terrible deal. Reps push leases because they get commission. You get stuck with high payments.
Fix: Buy used or refurbished when possible. Finance through your bank (4-6%) instead of the vendor (12-18%). Pay cash if you can - the ROI on most equipment doesn't justify 14% interest.
High Lab Costs Due to Remakes
If your lab bill is 12-14% of collections, check your remake rate. Are you sending back 10-15% of crowns for adjustments?
Every remake costs you the original lab fee plus chair time to reappoint the patient. That's $150-200 per mistake.
Fix: Improve your impression technique. Use digital scanners (eliminates impression errors). Communicate better with your lab (photos, shade, preferences). Switch labs if quality is inconsistent.
Paying Full Freight for Software You Barely Use
Are you paying $1,200/month for practice management software when you're only using 30% of the features? Paying for separate perio charting, imaging, and communication tools when an integrated platform would cost half as much?
Software vendors love to upsell add-ons. Most practices have 4-6 different logins for things that should be in one system.
Fix: Audit your software stack annually. Consolidate where possible. Negotiate - most vendors will discount 10-20% if you threaten to leave. Consider switching to newer platforms with better pricing.
The Overhead Audit: How to Find Your Leaks
Run this exercise quarterly:
Step 1: Pull your P&L for the last 12 months. Calculate each expense category as a percentage of collections.
Step 2: Compare to benchmarks:
- Staff: 25-28%
- Facility: 5-8%
- Supplies: 5-7%
- Lab: 8-12%
- Marketing: 2-5%
- Equipment: 3-6%
- Admin: 5-8%
Step 3: Identify outliers. If any category is 2+ percentage points above benchmark, dig in. Where's the waste?
Step 4: Create a 90-day action plan to cut the biggest leaks. Pick 2-3 high-impact fixes.
Examples:
- Staff at 32%? Eliminate one position through attrition or consolidation.
- Supplies at 9%? Renegotiate with vendors, switch to generics.
- Lab at 15%? Audit remake rate, tier your lab usage.
- Marketing at 8%? Kill underperforming channels, track ROI religiously.
Step 5: Re-run the numbers in 90 days. Did overhead drop? By how much?
Most practices can cut 3-5 percentage points of overhead with focused effort. On a $1.5M practice, that's $45K-75K straight to your bottom line.
When High Overhead Is Actually Fine
Not all overhead is bad. Sometimes you should be spending more, not less.
You're in Growth Mode
If you're scaling from $1M to $3M, overhead will spike temporarily. You're hiring ahead of production, investing in marketing, upgrading equipment. That's fine - as long as production is growing faster than overhead.
Target: Overhead spikes to 70-75% during growth, but drops back to 60-65% within 12-18 months as production stabilizes.
You're Investing in Retention
Paying staff 2-3% above market to retain top performers? That's smart, not wasteful. Turnover costs way more than retention premiums.
Same with associate compensation. If you're paying an extra $10K/year to keep a $500K producer, your overhead goes up 0.7%. That's a bargain compared to replacement cost.
You're Building Long-Term Value
Marketing spend that builds brand equity and patient loyalty pays off for years. Technology investments that improve patient experience and clinical outcomes are worth the cost.
Don't cut overhead just to hit a number. Cut waste. Invest in growth and quality.
THE TAKEAWAY
- Target 55-65% overhead for general practices. Staff (25-28%), facility (5-8%), supplies (5-7%), lab (8-12%), marketing (2-5%), equipment (3-6%), admin (5-8%). If you're over 70%, you're bleeding cash in at least two categories.
- Most waste hides in staffing, supplies, and marketing. Overstaffed front desk ($40K/year), premium supplies when generic works ($10K-15K/year), marketing with no ROI tracking ($20K-30K/year wasted). Audit these quarterly.
- Track overhead as percentage of collections, not absolute dollars. $900K overhead on $1.5M revenue (60%) is healthy. $900K overhead on $1.2M revenue (75%) is a crisis. Scale matters.
- Equipment leases at 12-18% are killing you. Finance through your bank at 4-6% or buy used. You're doubling the cost of every major purchase when you lease through vendors.
- Run a quarterly overhead audit and fix the biggest leaks first. Pull your P&L, compare to benchmarks, identify outliers, create a 90-day action plan. Most practices can cut 3-5 percentage points ($45K-75K on a $1.5M practice) with focused effort.
