2015 Federal Withholding Calculator

This calculator is to help you see how withholding allowances affect your pay. This allows you
to adjust your withholdings so you don’t get a refund.

If you want more information on how to use it, check out my blog post on Exemptions, Allowances and Deductions.

The best way to start is to take a current pay stub and input the values.
Verify that the Medicare, OASDI, Income Tax and Take Home Pay match that stub (they might be few cents off).
You can then change your withholding allowances and see how it will affect your take home pay.
