I have 4 ortho offices. These are things that I have to spend every month for office #1:
-Staff salaries: $5722
- Rent: $2385
- Utilities: $350
- Alarm: $40
- Business License: $70
- Property Tax: $50
- Supplies: $530
- Lab fees: $250
-Advertisement: $218
-Insurance (worker comp and property insurance):$250
- Other expenses: $200
Total: 10,065
Overhead for office 1: $10,065/month
Overhead for office 2: $8570/month
Overhead for office 3: $4085/month
Overhead for office 4: $1730/month
The grand monthly total is around $24K. I work 5 days/month at office 1, 4 days/month at office 2, 2 days/month at office 3, and 2 days/month at office 4. I have 3 full time and 7 part time employees, who travel with me to these 4 offices. Note that the overheads for office 3 and 4 are significantly lower. That's because I work fewer days and I rent the office spaces from the general dentists. I forgot to include the malpractice insurance, which is $2800/year.
My overhead is very low compare to other ortho offices because I still use paper charts and non-digital x ray. I don't have to pay expensive monthly IT supports to maintain expensive equipment. My lab fee is low because I make most ortho appliances in-house. The more outside services you rely on, the higher overhead you'll have.
