That title is kind of misleading; because if you're living in the "Real World," the question isn't how much will you make, but rather how much will you keep? Below is a form that will not only help you create a budget for yourself, it will also help you determine (predict) what your future "take home pay" will be.

Note: Although this tool is a good start, it does not take into account: additional income you may receive from other sources (i.e., a trust fund or investment dividends or interest) or additional expenses like car repair & maintenance, supplies, medicare, property taxes, homeowners insurance, dental, medical insurance, magazine & newspaper subscriptions, lawn care, babysitter, child care, vacation, clubs & activities, beauty & barber shop visits, music, animal care, student loan payments, life insurance, payroll deductions for retirement, lessons, and last but certainly not least, TUITION and BOOKS!
