Practice Overhead Ratio Calculator

Overhead is everything it costs to keep the doors open: staff, rent, supplies, billing, insurance, software. Your overhead ratio — overhead as a share of collections — is one of the quickest ways to judge a practice's financial health. This calculator works it out, compares it with typical ranges, and shows where the money goes.

What this calculator does

Choose your practice type and enter annual collections and your main cost categories: staff (wages, payroll taxes and benefits, excluding owners), rent and occupancy, medical and lab supplies, billing and administrative costs, malpractice and business insurance, and other operating costs. It shows:

• your overhead ratio,
• the typical range for your practice type,
• what's left for owner compensation, and
• the value of trimming overhead by one percentage point.

The chart shows each cost category as a share of collections.

The formula in plain English

Total overhead = staff + occupancy + supplies + billing and admin + insurance + other.

Overhead ratio = total overhead ÷ collections.

Left for owners = collections − total overhead.

Value of one point = collections × 1%.

Benchmarks in the calculator are editable rules of thumb, not survey results. Professional associations and groups such as MGMA publish detailed specialty data if you want a closer comparison.

A worked example

A two-physician primary care practice collected $1.2 million last year. Staff costs were $380,000, occupancy $96,000, supplies $70,000, billing and administration $90,000, insurance $30,000 and other costs $60,000.

• Total overhead: $726,000.
• Overhead ratio: about 60.5%, inside the typical 55%–65% range for primary care.
• Left for the two owners: $474,000.
• Each percentage point of overhead is worth $12,000 a year.

The biggest share is staff, at about 32% of collections. That isn't unusual, but it's also the area with the most room for change through scheduling, roles and productivity.

Why it matters at each career stage

If you're: Employed

If you're considering buying into a practice, ask for three years of overhead data. A high or rising ratio can mean lower partner pay than the recruiting pitch suggests.

If you're: Practice owner

Track your ratio quarterly. If it climbs, look first at staff and occupancy, then at billing performance. Sometimes the fix is on the revenue side: a higher collection rate lowers your ratio without cutting anything.

Reading the chart

Each bar shows one category as a share of collections, which makes it easy to spot outliers. A few rough guideposts many practices use: staff costs near 25% to 35% of collections, occupancy near 5% to 10%, and supplies near 4% to 8%, depending heavily on specialty. If one category is well above those ranges, start there. If every category looks reasonable but the total is high, the issue may be collections rather than costs — a low collection rate makes every expense look larger as a share of revenue.

Ways to lower overhead without hurting care

Match staffing to volume. Cross-train staff and use part-time roles for peak hours.

Audit your billing. Denied and unbilled claims are lost revenue. A better billing process can raise collections by several points.

Renegotiate contracts. Supplies, software, phones and cleaning are often worth re-bidding every few years.

Use space well. Extending hours or sharing space can spread rent over more visits.

Watch small subscriptions. Software tools add up quietly.

Overhead ratio vs. profit

A practice with 65% overhead and high collections may pay its owners more than one with 50% overhead and low collections. The ratio is a health check, not a scorecard. Always look at the dollars left for owners alongside it, and compare per-owner pay with what you'd earn as an employee.
