This is probably a kinda stupid and easy question.
I am trying to figure out the easiest way to determine how much extra we will take home vs pay in more taxes if I lower my husband's 401k contribution.
Is there a formula? I usually just make the change and wait and see what happens. Lame, I realize. I don't want to lower the deduction if that money is just going to get eaten up in taxes because our taxable income increases, but we want to travel more so taking home a bit more would be nice for that. (and yes I realize this is not FIRE friendly but oh well).
Thanks!
Jules
