Calculator to determine take home pay if switching to Roth?

[mila]

My H and I have been amazing our contribution to our 401k, but have decided to make the leap to switch to a Roth 401k plan in 2020.

Is there an easy to understand but still accurate calculator to determine what our take-home pay will be once we make this adjustment? Just trying to budget!

You might try plugging numbers into one of the options on www.paycheckcity.com/ I've used it in the past for various calculations.
