How This Calculator Works
Look at your pay stub sometime. That number at the bottom — the one that actually hits your bank — is way smaller than the number at the top. This calculator tells you why, line by line. All withholding calculations follow IRS Publication 15-T.
Here's what comes out of every paycheck. Federal tax uses progressive brackets from 10% up to 37%, with standard deductions of $16,100 (single) or $32,200 (married). Then FICA: 6.2% for Social Security on income up to $184,500, and 1.45% for Medicare on everything. Make over $200,000? Add another 0.9% Medicare surtax on the amount above that.
My buddy in Chicago and I compared stubs once. Same salary, same filing status. He walked away with about $3,800 less for the year because Illinois takes 4.95% and my state takes nothing. That's when it hit me — state tax is not a small factor. We cover five states here: Illinois at 4.95% flat, Texas at 0%, Florida at 0%, California at 1%–13.3% progressive, and New York at 4%–10.9% plus a potential NYC tax.
A couple things that help soften the blow:
- 401(k) contributions reduce taxable income at both federal and state level
- HSA contributions do the same
- These pre-tax deductions are basically a discount on your tax bill
Bottom line — you'll see your net pay, effective tax rate, and marginal rate. Most people think their effective rate is higher than it actually is. Go ahead, see for yourself.
