Chicago Paycheck Calculator

Free Chicago Paycheck Calculator 2025 – Easily Estimate Your Net Pay

Living and working in Chicago is an exciting experience, but understanding your paycheck is crucial for managing your budget and planning your financial future. Whether you’re new to the Windy City, considering a job offer, or just want a clearer picture of your earnings, our Chicago Paycheck Calculator is the perfect tool. This guide breaks down exactly how your take-home pay is calculated in Illinois, from federal and state taxes to common deductions.

How Your Chicago Paycheck is Calculated

Your gross pay—the number you see on your offer letter—isn’t what lands in your bank account. Several deductions are made first. Here’s a step-by-step breakdown of the key factors that determine your net (take-home) pay.

1. Federal Income Tax

This is the largest deduction for most people. The U.S. uses a progressive tax system, meaning higher portions of your income are taxed at higher rates. For 2025, there are seven federal tax brackets. The amount withheld depends on your income, filing status (Single, Married Filing Jointly, etc.), and information from your Form W-4.

2. FICA Taxes (Social Security and Medicare)

This is a standard federal payroll tax. It’s split into two parts:

• Social Security: A 6.2% tax is applied to your income up to the annual limit of $176,100 (for 2025).
• Medicare: A 1.45% tax is applied to all of your earnings, with no income cap. High earners may be subject to an additional Medicare surtax.

3. Illinois State Income Tax

Unlike the federal system, Illinois has a flat income tax rate of 4.95%. This simple, single rate applies to your adjusted gross income, making state tax calculations more straightforward than in states with progressive brackets.

4. Chicago and Cook County Local Taxes

Here’s some good news for Chicago workers: There is no city income tax in Chicago or local income tax in Cook County. Your wages are not subject to any additional local tax deductions, which simplifies your paycheck calculation.

5. Pre-Tax Deductions

These are funds taken out of your paycheck before any taxes are calculated, which lowers your taxable income and saves you money. Common examples include:

• Contributions to a 401(k) or 403(b) retirement plan.
• Health, dental, and vision insurance premiums.
• Contributions to a Health Savings Account (HSA) or Flexible Spending Account (FSA).

Paycheck Calculation Example in Chicago

Let’s imagine a Chicago resident who is single and earns a $75,000 annual salary. They are paid bi-weekly and contribute 5% of their income to a 401(k) and pay $150 per paycheck for health insurance.

1. Gross Pay Per Period: $75,000 / 26 pay periods = $2,884.62
2. Pre-Tax Deductions:
   • 401(k): $2,884.62 * 5% = $144.23
   • Health Insurance: $150
   • Total Deductions: $294.23
3. Taxable Income: $2,884.62 – $294.23 = $2,590.39
4. Taxes Withheld (Approximate):
   • Federal Tax: ~$275
   • FICA Taxes: ~$220
   • Illinois State Tax: ~$128
5. Estimated Take-Home Pay: $2,884.62 – $294.23 (Deductions) – $623 (Taxes) = ~$1,967.39 per paycheck

How Pay Frequency Affects Your Paycheck

Your pay frequency determines the size of each check.

• Weekly: 52 smaller paychecks per year.
• Bi-Weekly: 26 paychecks per year (most common).
• Semi-Monthly: 24 paychecks per year (e.g., paid on the 15th and 30th).
• Monthly: 12 larger paychecks per year.

While your annual pay remains the same, your pay frequency impacts cash flow and how you should budget.
