Calculator or spreadsheet for paycheck: FT going to half time?

[fidgiegirl]

Hi all,

I'm a teacher with a full time role. Considering going to half time next school year. Many half time roles; unfortunately, my department only does 1.0 or .5 FTEs.

With all the additional activity involved with my payroll, I know a change in my FTE wouldn't be as simple as taking home half what I take home now.

Does anyone know a good calculator or spreadsheet for predicting what my take-home would be? I'd have adjustments of taxes, healthcare contributions, pension contributions, probably other stuff . . . it's beyond my own knowledge to DIY this math. I don't need a precise value, but don't want an unpleasant surprise, either. (that's what happened last time I stuck my neck out to make this change - my take home was far lower than I had anticipated - and I had to turn tail and go back to FT within 6 weeks).

The case study spreadsheet will tell you your actual tax liability for the year.  How closely your withholding matches that is up to you.
