How the Washington Hourly Paycheck Calculator Works

The calculator determines your net paycheck by subtracting applicable taxes and deductions from your gross pay. Here’s a breakdown of how it works.

Core Logic & Formula

The core formula used in the Washington Hourly Paycheck Calculator is:

Gross Pay = (Hourly Rate × Regular Hours) + (Hourly Rate × 1.5 × Overtime Hours)

Taxable Income = Gross Pay - Pre-tax Deductions

Federal Income Tax = Based on IRS withholding tables  
Social Security Tax = 6.2% of Taxable Income  
Medicare Tax = 1.45% of Taxable Income  

Net Pay = Taxable Income - (Federal Tax + Social Security + Medicare + Post-tax Deductions)

Use the Oregon After-Tax Calculator to check your final take-home pay.

Input Fields Explained

• Hourly Rate ($): Your wage per hour before taxes or deductions.
• Hours Worked: Number of regular (non-overtime) hours worked during the pay period.
• Overtime Hours (1.5x): Enter hours worked beyond 40 hours/week. Overtime is paid at 1.5 times your regular rate.
• Pay Frequency: Choose how often you’re paid — weekly, biweekly, etc.
• Filing Status: Select your federal tax filing status (e.g., Single, Married Filing Jointly).
• Dependents: Enter how many dependents you claim for federal withholding purposes.
• 401(k) Contribution (% of gross): Enter the percentage of your gross income contributed to a retirement plan. Employees can also verify hourly wages with the Oregon Hourly Calculator.
• Health Insurance (per paycheck): Enter any pre-tax health insurance deductions.
• Other Post-Tax Deductions: Include Roth IRA contributions, union dues, or garnishments that are deducted after taxes.

Example Calculation (Verification Section)

Let’s walk through a sample input and output to understand how this calculator works.

Example Inputs:

• Hourly Rate: $22
• Hours Worked: 40
• Overtime Hours: 5
• Pay Frequency: Weekly
• Filing Status: Single
• Dependents: 0
• 401(k) Contribution: 5%
• Health Insurance: $40
• Other Post-Tax Deductions: $10

Step-by-Step Breakdown:

1. Gross Pay = (22 × 40) + (22 × 1.5 × 5) = $880 + $165 = $1,045
2. 401(k) Deduction (5%) = $52.25
3. Health Insurance (pre-tax) = $40
4. Taxable Income = $1,045 – $52.25 – $40 = $952.75
5. Social Security Tax = $952.75 × 6.2% = $59.07
6. Medicare Tax = $952.75 × 1.45% = $13.81
7. Federal Income Tax (estimated) = $75.00
8. Post-Tax Deductions = $10

Net Pay:

Net Pay = $952.75 – ($75 + $59.07 + $13.81 + $10) = $794.87

Interpretation:

This means your weekly take-home pay is approximately $794.87 after all federal taxes and deductions. This example shows how your contributions and filing status affect your net income. Calculate your net pay with the New Jersey Paycheck Calculator before finalizing your budget.
