We agreed to pay tuition, room & board and all expenses for their undergrad. We didn't have a set amount per child and didn't track to make it equitable. Their preferred college, within reason of course, is what we paid for.
Our family, life is not fair. It is the degree that was paid for, not how much the degree cost.
^^^This. We did not have college funds in place for the kids, but here in GA they could qualify for the HOPE scholarship, which pays 90% if you have a 3.0GPA in HS. Unfortunately, neither of them accomplished that. DD went away to college for one year and was able to qualify for a bunch of grants and one music scholarship, but she still had to take a small loan ($5500.) She decided after that to come home and go to a tech school to get a culinary degree. Grants covered almost all of that. She transferred to another tech school about a year into her program, so she could take advantage of their Baking program (she's primarily a pastry chef now.) While she was at the tech school 75 miles away, I paid for her share of the apt and utilities, and a little gas money. Otherwise, she was on her own. I probably came out of pocket for about $5000, all told.
DS really messed up. He went to the local tech school straight out of HS and received a couple grants which covered everything. Still, he blew it off and finally quit with a 0.9 GPA. He worked at various retail and food services jobs until he finally had to quit due to suicidal depression. We took him back in and gave him time to heal. After a few months he decided to go to the tech school and do the welding program. He qualified for a couple grants, which covered everything. The school was about 45 miles away, so rather than giving him gas money we allowed him to drive the Prius, which cost us about $5 a day, twice a week. DS has been here almost 2 years, working as a welder's helper and going to school full-time. He is set to graduate in August and we are ALL looking forward to him moving on.
I know I spent a lot more on DDs education than DSs. My rule was simple: Go to every class and don't fail anything. Period. No warnings, no do-overs. You flunk out, the money goes away, you go to work and move out. Both kids honored that. DS brought his horrible 0.9GPA up to a 3.0 in the last 18 months, which I think is pretty impressive. He is like a man on fire to learn and do well in school. I've told him that since he qualifies for free money, he'd be wise to take as many other core classes as he possibly can.
I'm really proud that my kids chose technical educations. Both of them graduated or will graduate with a skill that will provide them with a living straight out of the gate. DD is doing her dream job as head pastry chef at a popular restaurant; she plans to take extra training in the near future. DH is a little regretful that he didn't go to university, but it's still on the table. Welding pays well, so he will be able to support himself and go to college, if he wants to, especially if he can keep his GPA at 3.0.
And we can't wait for the day when we are truly empty nesters! 3 months and counting...
