<prompt> Human: I have been paying back my student loans on the 10 year plan for just over a year and a half right now. I can afford this amount, so I was going to continue paying it and more as I can afford it in future, but I was considering changing the underlying plan to the extended 25 year plan. My required minimum payment would drop to 333 from 636, but I would continue paying the 636.So, why? Well,1. it seems like this would allow some breathing room just in case I ever have an emergency. Same reason behind buying a house with a 30 year loan and paying it like 15.2. I believe the math works out with how they apply the extra payments to the higher interest loans that it would save me money, actually:Here are the details:Subsidized Principal Balance: 7,260.45 3.150 4,813.08 4.250 3,390.24 5.350Unsubsidized Principal Balance:34,293.72 6.550Standard plan: 636.33moExtended plan: 332.44mo estimated - they only told me 333 and 637 for my 636.33I already checked that my loan servicer applies extra payments to the highest rate loan: If there are multiple loans in an account, the extra amount, in this example 75, will be applied to the loan with the highest interest rate. sourceUsing Payoff.io thanks to another rpf-er for creating!, I find that according to my current repayment plan, I pay a total of 12,983.21 in interest with finishing May of 2023. With the extended, it comes out to 11,879.82 and March of 2023.Am I missing something here, or is this a no-risk way of saving 1100 and 2 months? I mean it gives emergency flexibility AND saves me money?Assistant: Sounds like youve got a good head on your shoulders. Lowering your minimum payments in order to put the most money into the highest rate loan will result in less interest paid.Human: The other question is whether or not to take the graduated extended plan as well. Even lower minimum payments, and as they increase, Ill be done by the time they exceed the 333 from the regular extended option.  <response>: I dont have specific knowledge of that kind of plan but if your minimums are lower on average for the duration of the loan and there are no fees then it allows you to put more towards the higher interest rate over the course of the loan. Im sure you already know this only works if youre committed to the additional payments which it sounds like you are.
