How to Use the Severance Pay Calculator
Losing a job or taking a voluntary separation is stressful enough without the uncertainty of not knowing what your severance check will actually look like after taxes. This severance pay calculator helps you estimate your gross severance, see exactly how much goes to federal and state taxes, and understand how many months of living expenses your net payout covers.
Step 1: Enter Your Annual Salary
Type your current gross annual salary — the number before any deductions. If your offer letter says $80,000 per year, enter 80000. This figure is used to calculate your weekly pay rate, which is the basis for the severance formula. It also determines how much of the Social Security wage base you have already used, which affects FICA withholding on the severance amount.
Step 2: Enter Your Years of Service
Enter how many years you worked at the company. Most employers round to the nearest full year, but some prorate partial years. The calculator uses whole or fractional years as entered. Your total severance scales directly with this number — more years means a larger payout.
Step 3: Choose Your Severance Formula
The most common severance formulas are one week of pay per year of service or two weeks per year. Select the formula that matches your employer's offer. If your package uses a different multiplier — such as three weeks per year for senior employees — choose "Custom" and enter the number of weeks. The calculator multiplies your weekly salary by the weeks-per-year figure and your years of service to determine gross severance.
Step 4: Select Filing Status and State
The IRS treats severance pay as supplemental wages and typically withholds federal tax at a flat 22% rate for amounts under $1 million. Your state selection applies a simplified state income tax rate — states like Texas, Florida, and Washington have no state income tax, so those fields will show $0. Filing status is shown for reference; the federal supplemental rate of 22% applies regardless of filing status for withholding purposes.
Understanding Your Results
The results show your gross severance, a detailed tax breakdown (federal, Social Security, Medicare, and state), and your net take-home amount. The "Months of Salary" metric shows how many months of gross salary your severance represents, while the "Emergency Fund" estimate shows how many months of essential expenses your net severance could cover, assuming roughly 70% of gross monthly salary goes to essential expenses. Use these figures to plan your job search timeline and budget accordingly.
Important Considerations
Severance pay is not legally required in most US states — it is offered at the employer's discretion or as part of a negotiated agreement. Before signing a severance agreement, review the terms carefully, including non-compete clauses, confidentiality provisions, and the release of legal claims. If the package seems low, negotiation is often possible, especially during mass layoffs or for employees with significant tenure. Consider consulting an employment attorney for large packages or complex situations.
FAQ
Is this severance pay calculator free?
Yes, completely free with no signup, no account, and no limits. All calculations run entirely in your browser using JavaScript — nothing is sent to any server, so your salary and severance information stays completely private on your device.
Is my salary and severance information private?
Absolutely. This tool runs 100% client-side in your browser. No figures you enter are ever transmitted over the internet or stored anywhere. You can disconnect from the internet after the page loads and the calculator will still work perfectly.
How is severance pay typically calculated?
The most common formula is one or two weeks of pay per year of service. For example, if you earned $80,000 per year and worked for 5 years with a 2-weeks-per-year formula, your gross severance would be $15,384.62. Some employers offer more generous packages, especially for senior roles or during mass layoffs.
Is severance pay taxed like regular income?
Yes. The IRS treats severance pay as supplemental wages, which means employers typically withhold federal tax at the flat supplemental rate of 22% for amounts under $1 million. State income taxes and FICA (Social Security and Medicare) also apply, just like regular wages.
Does severance pay affect my unemployment benefits?
It depends on your state. Some states delay unemployment benefits while you receive severance pay, while others allow you to collect both simultaneously. Check your state's unemployment office for specific rules before making financial plans based on receiving both.
Can I negotiate a higher severance package?
Often yes, especially if you have leverage such as knowledge of company practices, pending projects, or potential legal claims. Many employers expect some negotiation. Consider consulting an employment attorney before signing a severance agreement, particularly for senior positions or large packages.
What is the Social Security wage base for severance?
For 2025, the Social Security wage base is $176,100. If your regular salary plus severance exceeds this amount, Social Security tax (6.2%) applies only up to that cap. Medicare tax (1.45%) has no cap and applies to the entire severance amount regardless of total earnings.
