First of all, you won't take home 3 mill. As a dentist, you will be close to the 50% tax bracket. Now, if you make 100,000 a year, then you will only take home 65-75,000. That is 6250 a month. Now, subtract your 2300 for loan payments (and this is over 10 years) and you now have 3950 a month. Now, let's say you bought your dental practice for 450,000. That is another 5,178 a month for that loan payment over 10 years. You now have NO money left at the end of the month. No car, no house, no food, no nothing. And you are in the hole. So, for all of you that think money is not a big deal, think again. IT IS! Look at the cold hard facts before jumping into your amazing, prestigous, expensive school.
