Not so fast my friend, IBR helps if you have a high debt and a modest income as well. I'm a dentist, with $297,000 in student loans, and I make about 130k a year. I graduated in 2011, and my IBR payments are currently $0. This is because I was in school in 2010, and had no income shown on 2010 tax return. My 2011 tax return will show about 50k (I worked from July to the end of the year). This will make my monthly payments about $700 for all of 2013. They will use my 2012 tax return for my payments in 2014, which will be around 1300 per month. If I make about 150k for the next 25 years, I will come out way ahead if I stay on the IBR plan.
The only thing I'm worried about is this: at the end of my 25 years on IBR, they will forgive my loans and any outstanding interest. ARE THEY GOING TO COUNT THAT AMOUNT FORGIVEN AS TAXABLE INCOME??? That will hit me hard if they do. But there are indications that they will change it so it will not be taxed. If that's the case, I will save about 200k in total payments during those 25 years, compared to the standard repayment plan.
I'm going for IBR all the way.
