457 question/online calculator?

[PartyOf5]

I have a 401k and I'm familiar with how that works. However, DH has a 457 and I'm a little fuzzy there. He is thinking about reducing his deductions so that he gets more in his paycheck to put towards bills. My gut says this is a mistake.

Aren't 457's pretax? If so, does anyone know of an online calculator where I can show him what his paycheck looks like now vs. what it would look like if contributions are reduced?

Thanks!

Yes... a 457 is a deferred compensation plan for public employees, so you don't pay any federal tax on the money until you withdraw it at retirement.
