Does anyone know if there is a income calculator spreadsheet available?

I'm about to start the daunting task of creating a new POI calculator for my company. I was curious if there was a spreadsheet out there that was already created that I might learn from. Essentially, I'm looking for a spreadsheet that calculates peoples income from their paystubs - the user simply inputs the pay period ending date, hourly/taxes/etc.. and it calculates income monthly. Not too complicated, but quite a bit of work to make for several different types of income (W2, 1099, 1040, etc).

It only seems like the best idea to ask before I start on it. Any help would be greatly appreciated.

That's a payroll calculator for what looks like an HR department or something to calcuate tax rates. I'm trying to calculate income off a paystub unfortunately. Thanks for the help though!
