We took a slightly different approach. Have a 3 month emergency fund, then pay every extra dollar towards the student loan. Paid it off in 3.5 years instead of the 20year plan NelNet wanted. Now we are building out a 6-12month emergency fund and putting money into retirement. Maybe in the short term we are behind in retirement saving, but now we have a lot more cash every month to put into savings and investing. I would still recommend this approach because it emotionally feels wonderful to pay that last f*ing payment :)

But sometime emotions get in the way of financial strategy.
