A federal tax calculator should explain more than one final number. This calculator separates federal income tax from Social Security and Medicare so you can see the difference between regular federal tax and FICA tax. It also estimates the federal tax rate that applies to your next dollar of taxable income, then compares it with your effective tax rate.
