This is a big thing, and something we need to sit down and really illustrate for her. I don't think she's thought through what it would look like to have to start each month already being down that amount. And you're right - it does change the place she can live in for a while, or the car she can drive, or the vacations she can take, etc.
I ran into this, on a much smaller scale, with my oldest and graduate school. Our deal with them has always been that they'd go through undergrad with no loans, through a combination of us paying, and them limiting their options to what they could pay for. Basically, they can get up to about $18k a year on us, so they've got to find some place they can go for that all in.
But graduate school and the loans were always going to be on them.
My daughter had an odd result to graduate school admissions. Well, weird to us, as she's the first person in our family to go through grad school admissions...no I understand it's not that uncommon.
She applied to several schools outside Georgia (including her undergrad Alabama), and several schools in Georgia. She ended up getting accepted to good to great programs out of state and Alabama, and rejected by all the Georgia schools except her absolute safety, the worst one (GA Southern). It was really weird that she would get accepted by a top-10 program in Chicago, but stiff armed by Georgia State.
So she was looking at the options:
Top 10 program - $75k+ in loans for 5 semesters grad school
Alabama - $60k in loans for 5 semesters
GA Southern - $20k in loans
I felt bad for the outcome, she had assumed UGA or Georgia State was her "safety". And the program/facilities for GA Southern was pretty craptacular. The only appealing characteristic was that it was in Savannah, GA.
But her field, where you go to school has almost no bearing. You just need the piece of paper, that's it. Fully half of the program is two internships...it's only like 7 actual classes. And you don't start with much in your first job...usually in the high $50s.
She really, really wanted to stay at Alabama and eat the $60k loans. I finally showed her that repayment schedule, which was something like $700/month for ten years. That she'd still be paying that in her 30s. Luckily, at 21 she had a better fix on what they meant...she'd lived in apartments by that time and knew what $700 more dollars got you. She knew that would be that much longer she'd be driving the mom car we gave her.
Looking at that payment schedule, with "Age 31" instead of "Year 8", was the thing that turned it around for her.
It worked out very well. She broke up with her Alabama boyfriend like six months later, and never talked about wishing she was at Alabama again. The GA Southern program had some elements that were just as shitty as expected, but the functional education was good enough. She enjoyed Savannah, made life long friends (she's been in two weddings already), and had a great job lined up in the location of her choice months before graduation (and had several other offers).
She can afford a much nicer apartment now, is planning vacations, with a more affordable debt load she'll be able to knock off in a few years. She's very happy that emotions didn't rule the day.
