I try to save 20%. After that I'm putting extra money to trips and bathroom reno. I do budget.

I would definitely allocate $7000 a year to put into a backdoor Roth IRA.

The rest I would put the rest into a 529 if you are not already at the limit for which you get a state tax break.

You need to be investing it, not saving. They will ramp up money printing. choose your top ten companies and Bitcoin Etf, or VOO if scared. This is money for your kid as you don't need it. Do not lock it up in 529. Put it into Roths if possible and add the kid as beneficiary once they turn 18.
