How the Calculator Works

This calculator works by subtracting mandatory taxes and voluntary contributions from your gross income to determine your net pay. It accounts for federal income tax, Missouri state income tax, Social Security, Medicare, and 401(k) contributions.

Input Fields Explained

  • Gross Pay ($): Your total earnings before any deductions. Enter the amount based on your pay period.
  • Pay Frequency: Select how often you’re paid (weekly, biweekly, monthly).
  • Filing Status: Choose your federal filing status (Single, Married, etc.), which affects your federal tax rate.
  • Number of Dependents: Dependents can reduce taxable income, so it’s important to include them for a more accurate result.
  • 401(k) Contribution (%): If you contribute to a 401(k) retirement plan, enter the percentage of your gross pay that goes into it.

Core Calculation Formula

The calculator applies the following simplified formula:

Net Pay = Gross Pay
         – Federal Income Tax
         – Missouri State Income Tax
         – Social Security Tax (6.2%)
         – Medicare Tax (1.45%)
         – 401(k) Contribution (if any)

Example Calculation (Verification Section)

Let’s walk through a sample calculation:

Inputs:

  • Gross Pay: $2,000
  • Pay Frequency: Weekly
  • Filing Status: Single
  • Number of Dependents: 0
  • 401(k) Contribution: 5%

Step-by-Step Calculation:

  1. 401(k) Deduction:
    $2,000 × 5% = $100 → New taxable income = $1,900
  2. Federal Tax Estimate: ~$150
  3. Missouri State Income Tax: ~$60
  4. Social Security Tax: $2,000 × 6.2% = $124
  5. Medicare Tax: $2,000 × 1.45% = $29

Final Net Pay:
$2,000 – ($100 + $150 + $60 + $124 + $29) = $1,537

Interpretation:

After all deductions, the employee takes home approximately $1,537 for that week. This demonstrates how your inputs directly influence your net earnings.
