[Editor’s Note: This is another in our ongoing series aimed at dentists by columnist Doug Carlsen, DDS. The principles espoused are useful for high-income professionals of all persuasions.]

Two months ago, I wrote of a recent dental graduate who has $10,000 per month payments for school loans, a mortgage, an auto, a new dental practice, and credit cards.  His total debt is $1.175M.

The responses on The White Coat Investor blog ranged from outrage to resignation to recognition.  This month I’d like to provide figures on what a new dentist can expect to pay for various expenses with an average income. After interviewing young dentists over the last five years and cross-referencing to BLS income quintiles of those with incomes matching what young dentists may make in a corporate environment, we can understand better how some dentists are able to pay down student loans quickly and how others may struggle.

Dentist Income

Let’s look at income and expenses for the young dentist:

Income for young dentists in the corporate environment, according to, averages $111,000 at Western Dental, $167,000 at Pacific Dental Services, and $138,000 at Heartland Dental.  For this article, I used $125,000 income for all young dentists, whether working for a corporation or in an associateship. Of course, after owning a practice, either in start-up or after purchase, net incomes vary widely.

Sample Dentist Budgets

The table below has five columns: the single doctor with expenses average for his BLS quintiles, the married doctor with average expenses, the high spending single doctor, the high spending married doctor, and space for you to place your expenses and income.  It is assumed that the dentist’s income is $125,000 annually and his spouse’s income (included in parentheses) is $50,000.

Differences between the average spending dentist and the high spending dentist are listed below. It is assumed the spouse spends as does the doctor.  Expense differences not commented on below reflect differences in overall lifestyle.


Average dentist High Spender
Owns a five-year-old used car Leases auto and renews every three years
Dines out weekly at a nice restaurant High spender spends double on dining out
Shops for groceries at a typical market Shops at Whole Foods only
Rents an apartment Bought a home with $600,000 mortgage
No cash value life insurance $300,000 whole life policy
Vacations are all road trips One resort trip and several fly-in get-a-ways annually

Average Spender vs High Spender

The average-spending single dentist ends up with $42,600 annually and $59,040 if he or she is married, to pay down debt or save.  The high-spending dentist ends up with near nothing annually and about $11,000 if married.

It’s possible to live with expenses lower than the $42,600 found for the average single young dentist.  $3,000 per month is not unusual for a single dentist; $4,000 for a couple.  This implies that dentists, even without a great salary, can pay off $50,000+ per year in loans.  The best pay down I’ve seen has been $9,000 per month on a $273,000 debt, which required 30 months of payments by a married dentist working in a corporate clinic in Texas.


If you like to dive into the details, here are the assumptions I used:

All expenditure figures are taken from interviews of young dentists under age 40, cross-referenced to BLS 2013 quintiles of income before taxes (top two quintiles).  First column is average expenditures whether renting or owning home. Dentist in second column bought $600,000 home. Tax estimates provided by  With home purchase, it’s assumed the couple will take itemized deductions.  The interest deduction is assumed to save taxes of approximately 25% of interest paid on $600,000 home, or $7,500 annually for federal taxes and $1,500 for state taxes.  State tax of 5% is used, but obviously can vary widely.

Your Own Budget

You can use the form above to estimate your own expenses. Use these links to estimate federal taxes and state taxes. Remember these tables may not include all of your expenses. You may need to add other insurance, pets, legal fees, country clubs, and other expenditures.

The difference between various budgets can be amazing, but controlling spending is a key to wealth accumulation. Earning a high salary while spending similarly to others at that high salary as illustrated above helps. It can be even more effective to earn a high salary while spending at the level of someone with a much lower salary.

What do you think? Are these budget numbers realistic? How fast do you think a dentist should pay off student loans? Comment below!
