Based on what you’ve said, you’re saving $28,200 a year (10.4k 403b, 7k HSA, 6k Roth, 4.8k 529). If your expenses are $2,100 a month, that comes to $25,200, for a total of $53,400 out of your gross pay of $55,500. So unless your effective tax rate is 3%, those numbers don’t work out.
On the other hand, if you saved for retirement at that level, you’d hit a stash of $630k (25x expenses) by age 53, much sooner than your planned date of 65. In fact, you’d only need to save $5500 for retirement each year if you wanted to be set by 65. So there’s a lot of flex in your current plans.
