Formula Behind the Calculator

The calculator uses a step-by-step approach:

  1. Gross Pay
    Total earnings before deductions.
  2. Federal Income Tax (FIT)
    Based on IRS tax brackets and your filing status.
  3. FICA Taxes
    • Social Security = Gross Pay × 6.2% (up to wage base limit)
    • Medicare = Gross Pay × 1.45% (additional 0.9% for high earners)
  4. Wisconsin State Income Tax
    As of 2025, Wisconsin has a progressive tax system with rates from around 3.5% to 7.65%, depending on income bracket.
  5. Other Deductions
    Such as 401(k), health insurance, or union dues.
  6. Net Pay
    Net Pay = Gross Pay – (Federal Tax + FICA + WI State Tax + Other Deductions)

Example Calculation

Let’s assume:

  • Gross Monthly Salary: $5,000
  • Filing Status: Single
  • Pay Frequency: Monthly
  • No additional deductions

Step 1: Federal Tax (Approx.)
About $500 withheld.

Step 2: Social Security
$5,000 × 6.2% = $310

Step 3: Medicare
$5,000 × 1.45% = $72.50

Step 4: WI State Tax (Approx.)
$5,000 × 5% = $250

Step 5: Net Pay
$5,000 – (500 + 310 + 72.50 + 250) = $3,867.50

So, the employee would take home about $3,867 each month.
