Well, I just sat down with my finance professor (at least I got something worthwhile from my time in this business school), and he we discussed the economics of a dental education at length. Yes, Tinkerbell, you can consolidate down up to 30 years. Many companies will do this, most notably Sallie Mae's SMART LOAN. Check their website for details. Please review my numbers and see what you think. These are geared toward my tentative career plans at this point, your mileage may vary.
We start with a salary of 100K, for simplicity's sake. This may be a tad optimistic in today's money, but by the time many of us begin practice, inflation will have brought it to an average salary for a new associate. This nets out to around 65K in Minnesota, a very high tax state, or around 71K in a low tax state such as Florida, at 2003 tax rates. I used multiple calculators online to arrive at this net amount. This also assumes no deductions, even though the new dentist will certainly deduct loan payments and interest and other applicable writeoffs.
Let's also assume a debt of 250K, not at all unrealistic if at a private school or if carrying undergrad debt. Amortized at a more realistic rate of 7%, over 30 years, we get a monthly payment of $1,663, or approximately 20,000 per annum.
Subtracting the 20K from the 65K in Minnesota yields a net income after loan repayment of 45K. This is equal to a salary with no loans of around 68K in MN. This is equivalent to a pretty solid business job or other health profession career, and provides a good living wage for a single person, enough to afford a nice apartment and a reasonably nice car.
If you add in a spouse, this picture improves. Throw out the idea of marrying rich, and lets use a figure of 50K for their salary. This can be earned as a nurse, accountant, mid-level manager, or even your hygenist! Remember, as highly educated and relatively wealthy professionals, we should be pretty desirable to the opposite sex and can be a little picky. Your combined income of 150K breaks down to a net of 98K in the tax hell of MN with no non-standard deductions, which is a worst case tax scenario. Take out the 20K in loans, and you are left with 78K. A 78K shared net income with no children in your late twenties is darn good! At this financial level, a couple could afford a home of at least 300K and two 25K+ cars, and be saving a good amount for the future.
Bear in mind that this is all a (reasonably and forseeably) worst case scenario. After your associateship, upon entry to private practice ownership, your income will increase even more. Even a modest increase to 130K (below average) as a practice owner will give plenty of room to ratchet up the standard of living even more. Also, keep in mind the time value of money and inflation. A DDS may have had a "monster debt" of 50K back in the mid 70s from a private school, and would have financed it over 30 years. Payments of $340 per month back then would have looked staggering, but are now laughable on his mature salary of approximately 150K. Another way to think of this whole thing is this. Say the actual cost of a 250K loan at 7% over 30 years is 600K. Add in the opportunity cost of not working for four years at a young, entry level job, to reach 750K. Divide this over a working life of 35 years. The answer is around 22K per year. If you make an average of 150K for the life of your career (and you WILL be making more in 2030), ask yourself this. Could you have found something else stable and legal that would have paid you 128K for 35 years? Most people, even in the highest paying fields, never will.
My only worry is that something would happen that would make earning enough money impossible, such as an illness or injury, death, or a major shift in the dental economic landscape, such as widespread and oppressive managed care, a major innovation that decreased demand, or a large increase in dental school graduates.
Also, in my case, I intend to apply for the military scholarships (I already have a military background), and will likely practice in a rural area with a low cost of living, since that is where I grew up and would like to return to raise a family. I can understand how USC is possible now. Full speed ahead!
