Keep in mind that even though there are many ways to lower your monthly payment, there is no circumstance where paying off a loan faster will cause you to spend more money in the long run. If there is anyway you can afford to sign up for a standard 10 year plan I would advise it. Signing up for IBR or PAYE and then just making bigger payments as if you were on a 10 year plan is a logical way to do it (so you don't
have to pay a lot in a month if you get desperate). However, it is easy to fall prey to the temptation too just make the minimum payment just this one month so that we can buy the sofa we need. And then it happens another month and another month. Paying off a loan in less than 10 years when you aren't on a 10 year plan takes discipline and budgeting skills. Most people with student loans could save themselves thousands and thousands of dollars in the long term of their life if they would sacrifice for a couple more years of living like poor college students and dumping most of their income into loans.
Obviously everyone's situation is different so take this all with a grain of salt. These are just some of my rambling thoughts at the moment.
The main point is that there is no circumstance where it is better to be in debt than to not be in debt. So let that seemingly very obvious yet often forgotten principle guide your decision making.
