A lot of people have been reaching Bargaineering because they asked: “What tax bracket am I in?”
So, to solve this problem and to redirect people from other pages to this one, I’ve decided to offer up this simple to use calculator.
Enter your pre-tax, post-deduction (after your 401k contributions and medical expenses) salary and click “What bracket am I in?”
The calculator will spit out the marginal tax bracket you are in.

This calculator is based on 2009 tax bracket data.
This page has the current IRS federal income tax brackets  and remember, this is your marginal tax rate. Your actual marginal tax rate  may be lower based on deductions, exemptions, credits, etc.
