How is This Calculated?

The calculator took the income you provided, then reduced it by amounts equal to your allowable deduction for dependents and the greater of your standard deduction or the itemized deduction you provided. Federal income taxes were then calculated using the 2014 tax schedule. The alternative minimum tax was also calculated and the greater of these two was used to estimate your federal income taxes owed.

Social Security was based only on wages and earnings (not investment income) and up to the current income limit of $117,000. It is 6.4% of wages and earnings if an employee, 12.2% if self employed on wages and earnings up to this amount. Medicare is 1.45% of wages and earnings for employees and 2.9% of wages and earnings if you are self employed with no limit and a surtax for incomes over $250,000 for married couples, $200,000 for everyone else.
