Bonus Paycheck Calculator
Your Estimated Net Bonus

Understanding Your Bonus Paycheck
Receiving a bonus is a great way to be recognized for your hard work, but it's important to understand how taxes affect the actual amount you'll take home. This calculator helps you estimate the net amount of your bonus after mandatory deductions.
How the Calculation Works:
The calculation involves subtracting various taxes from the gross bonus amount. The primary deductions are:
- Federal Income Tax: This is a progressive tax, meaning higher income is taxed at higher rates. The rate you input here is a simplified percentage, often determined by your W-4 form and filing status. For bonuses, employers may use a "percentage method" or "aggregate method" to withhold taxes, which can sometimes lead to a higher initial withholding than on regular wages.
- State Income Tax: Similar to federal tax, but levied by your state government. Tax rates vary significantly by state. Some states have no income tax.
- FICA Taxes: This stands for the Federal Insurance Contributions Act. It covers Social Security and Medicare taxes. For 2023 and 2024, the Social Security tax rate is 6.2% on earnings up to a certain limit ($160,200 for 2023, $168,600 for 2024), and the Medicare tax rate is 1.45% on all earnings. The combined FICA rate is typically 7.65%.
The formula used is:
Net Bonus = Gross Bonus - (Gross Bonus * Federal Tax Rate / 100) - (Gross Bonus * State Tax Rate / 100) - (Gross Bonus * FICA Tax Rate / 100)
For example, if you receive a gross bonus of $1,000 with a 22% federal tax rate, a 5% state tax rate, and a 7.65% FICA tax rate:
- Federal Tax Withholding: $1,000 * 0.22 = $220
- State Tax Withholding: $1,000 * 0.05 = $50
- FICA Tax Withholding: $1,000 * 0.0765 = $76.50
- Total Deductions: $220 + $50 + $76.50 = $346.50
- Net Bonus: $1,000 – $346.50 = $653.50
Disclaimer: This calculator provides an estimate. Actual withholdings may vary based on your specific tax situation, local taxes, and your employer's payroll practices. Consult a tax professional for personalized advice.
