About the Severance Pay Calculator

A severance offer usually lands with a number attached, but it's worth checking that number against a standard formula before signing anything. This calculator estimates a severance package the common way many employers structure one: a set number of weeks of pay for every year you worked, plus any flat additional weeks offered.

How It Works

The calculator multiplies your years of service by the weeks of pay offered per year of service, adds any additional flat weeks, and multiplies the total number of weeks by your weekly pay to get an estimated severance amount.

Total weeks = (years of service x weeks per year of service) + additional flat weeks Severance pay = total weeks x weekly pay

Examples

Standard offer

An employee earning $1,500 a week with 6 years of service and a 2-weeks-per-year formula would be offered 12 weeks of pay, totaling $18,000, or roughly 2.8 months of equivalent pay.

With a flat bonus

The same offer with an additional 4 flat weeks added on top (common in some negotiated exits) raises the total to 16 weeks, or $24,000.

Advantages

  • Converts total weeks of severance into an equivalent number of months for easier budgeting
  • Separates the base formula (years times weeks per year) from any additional flat weeks offered
  • Quick way to check an employer's offer against a standard formula

Common Mistakes

  • Assuming severance is taxed differently from regular wages - it's generally treated as supplemental income subject to the same federal, FICA, and state taxes as a bonus
  • Overlooking non-cash elements of an offer, like COBRA subsidies or accelerated vesting, that this calculator doesn't capture
  • Treating a stated formula as legally guaranteed when most severance in the private sector is discretionary, not mandated

Edge Cases to Watch For

  • Severance formulas aren't standardized or required by federal law in most cases, so this calculator's structure is a common pattern, not a legal requirement your employer must follow.
  • The WARN Act does require advance notice (or pay in lieu of notice) for larger layoffs at bigger employers, which is a separate legal requirement from a voluntary severance formula.
  • Some severance offers include additional elements this calculator doesn't model, like continued health insurance (COBRA subsidies), unused PTO payout, or accelerated equity vesting.

Common Use Cases

  • Estimating a likely severance package before a layoff conversation
  • Checking whether an employer's offer matches a standard weeks-per-year formula
  • Budgeting for the months an estimated severance payout would cover

Frequently asked questions

Is severance pay taxed differently from regular wages?

No - severance is generally treated as supplemental wages and subject to the same federal (22% flat rate for withholding purposes), FICA, and state taxes as a bonus, even though it isn't pay for time worked.

Conclusion

Severance is negotiable far more often than people realize, and knowing what a standard formula would produce gives you a benchmark to push from. Read your actual employee handbook or offer letter for the real formula your employer uses, since defaults vary widely by company and role.
