$200,000 for Texas A&M undergrad? I hope ROI was there for the kid.
Here's my experience.
We put away $300 per month in 529 for each of our kids since they were 1 or so. Daughter started college in 2017 with about $110,000 in the 529 account. She went to UC Davis as we are CA residents. As we started to pay, the 529 continued to grow. I think about her 2nd year, I converted her account from index fund to cash. She graduated in 2021 with $35,000 left in her 529 account. She then went to Cornell Law School, $90,000 per year with some scholarship and she will graduate this May with about $150,000 in loans. She does have a corp Law job lined up and she shouldn't have issues paying back the loan.
Son has about $125,000 in his 529 account (all from $300 per month) and he will start college this fall. He's a much better student than the daughter. Our expectation is he'll go to a smaller liberal arts college with a full scholarship for 4 years and his 529 will be spent on his grad program.
Here's some additional comments and I know you didn't ask. I also know majority of people will disagree but here goes.
"Pursue happiness," "do what you love," "study what you're good at" are the biggest BS we can feed our kids. Because I know if that's what I did, I'd be a poor ass broke musician and a driving range pro giving golf lessons and I'd be very unhappy.
I grilled "Pursue Excellence" and "happiness will come and go" but look carefully at how you want to live your life in detail to where, what kind of house and choose a profession that can affords you the life. In that, you will find happiness, excellence, and will learn to love what you do. Whatever you love doing, keep it as a hobby unless you're Tom Cruise or Tiger Woods good.
Sorry...
TLDR, $200,000 for undergrad is too much.
