Severance Pay Calculator
Estimate a layoff package with the same pieces HR usually uses
Severance is one of those numbers people often need quickly, but the details rarely live in one place. An offer letter may tell you annual salary, an employee handbook may describe a policy such as one week per year of service, a manager may mention paying out unused vacation, and a separation agreement may add a one-time cash amount. This calculator brings those pieces together into one gross estimate so you can move from a vague policy statement to a dollar figure you can actually discuss.
That makes the tool useful in several real situations. Employees use it to estimate financial runway after a layoff. Managers and founders use it to model the cost of different severance policies. HR teams use a quick estimate to check that an offer feels internally consistent before a formal review. The result is not a contract and it is not legal advice, but it is a practical first-pass number when you need to compare scenarios without opening a full spreadsheet.
What this calculator includes
The estimate here is intentionally straightforward. First, the calculator converts annual salary into weekly pay by dividing by 52. Then it multiplies that weekly amount by years of service and by the severance weeks per year of service policy. After that, it adds the value of unused vacation days and any additional lump sum. In plain language, it combines the main recurring part of severance with the two common extras people often forget to include.
The fields matter in different ways. Salary sets the pay rate. Years of service measures how long that rate has been earned. Weeks per year of service is the policy lever that turns tenure into severance. Vacation days represent accrued paid time that may be cashed out depending on policy or local law. The additional lump sum field covers negotiated payments, transition bonuses, or one-time flat amounts that are not tied directly to tenure.
How to enter the inputs without distorting the estimate
A good severance estimate mostly comes down to entering each input in the way the formula expects. The salary field should be annual pay in dollars, not monthly pay and not hourly wage unless you have already converted it. Years of service can be a whole number or a decimal if your policy recognizes partial years. A value of 1 in the severance policy field means one week of pay for every year worked; 1.5 means one and a half weeks per year; 2 means two weeks per year.
| Input | What to enter | Why it matters |
|---|---|---|
| Annual Salary ($) | Your annual base pay in dollars. | This becomes weekly pay when the calculator divides salary by 52. |
| Years of Service | Total completed years, or a decimal if partial years count. | Longer tenure usually raises the base severance amount directly. |
| Severance Weeks per Year of Service | The policy multiplier you want to model, such as 1, 1.5, or 2. | This is often the biggest policy variable in the estimate. |
| Unused Vacation Days | Any paid vacation days expected to be cashed out. | The calculator values vacation using a five-day workweek. |
| Additional Lump Sum ($) | Any flat extra payment in dollars. | This captures negotiated or policy-based one-time additions. |
The default values in the form are examples, not recommendations. Replace them with your own numbers before you rely on the result. If you are unsure about one input, run at least two scenarios: a conservative case and a more generous case. That gives you a range instead of a single number that may look precise but rests on an uncertain assumption.
Formula behind the estimate
For this severance model, the calculation is explicit. Let annual salary be S, years of service be Y, severance weeks per year be W, unused vacation days be V, and additional lump sum be B. The calculator first computes weekly pay as S/52. It then multiplies weekly pay by Y and W to get base severance. Vacation pay uses the same weekly amount divided by 5, which is equivalent to using S/260 as a daily rate. Finally, it adds the lump sum.
Written in words, the estimate is: weekly pay × years of service × weeks per year, plus daily pay × unused vacation days, plus any flat extra amount. That structure is helpful because you can see what will move the total the fastest. A higher salary raises both the base severance term and the vacation term. More years of service raise only the base severance term. A bigger bonus changes the total one-for-one.
If you like the more abstract view, the calculator still follows the general pattern shown below: a result is a function of several inputs, and a total can be expressed as the sum of weighted components. Those MathML formulas are preserved here because they reflect the broader structure behind many estimation tools.
Worked example
Suppose someone earns $78,000 per year, has worked for 6 years, is offered 1.5 weeks of pay per year of service, has 5 unused vacation days, and will also receive a $2,000 lump-sum payment. The weekly pay is $78,000 ÷ 52 = $1,500. Base severance is $1,500 × 6 × 1.5 = $13,500.
Next, the vacation payout uses a daily rate of $1,500 ÷ 5 = $300 per day. Five unused days add $1,500. Then the calculator adds the extra lump sum of $2,000. The final gross estimate is $13,500 + $1,500 + $2,000 = $17,000. That is the number you should expect this calculator to produce for that exact set of inputs.
This example is worth remembering because it shows how to sanity-check your own result. If your weekly pay looks off, check the salary entry first. If the final estimate feels too low or too high, ask whether the weeks-per-year policy was entered correctly. In many real-world scenarios, that single policy field changes the total by more than vacation days or a modest flat bonus.
How to interpret the result
When you press calculate, the result is best read as a gross estimate. It tells you what the package looks like before payroll withholding, taxes, benefits continuation costs, or other deductions. It is especially useful for comparing scenarios. For example, you might keep salary and vacation fixed while testing what happens if a policy is 1 week per year versus 1.5 or 2 weeks per year. That comparison is often more valuable than any single point estimate.
A quick scenario table using the same example numbers above shows how sensitive the estimate can be to the policy multiplier:
| Scenario | Weeks per year | Estimated total | What changed |
|---|---|---|---|
| Lower policy | 1.0 | $12,500 | Base severance falls while vacation and bonus stay the same. |
| Mid policy | 1.5 | $17,000 | This is the worked example shown above. |
| Higher policy | 2.0 | $21,500 | A larger weeks-per-year multiplier raises only the base severance term. |
If you are reviewing an actual separation package, this table-style thinking is useful. You can compare the offered terms against a stricter internal policy, a more generous negotiated package, or a budget-limited option. The calculator helps you isolate which assumption is doing the work. That is especially important when two packages have similar totals but very different structures, such as a lower weeks-per-year policy paired with a larger one-time payment.
Assumptions and limits you should know before relying on the number
No simple calculator can capture every legal and policy detail. This page assumes a five-day workweek for valuing unused vacation because the JavaScript uses weekly pay divided by 5. It also assumes annual salary is the right starting point. If your compensation structure includes variable commission, overtime, equity, statutory notice pay, COBRA support, benefit continuation, or country-specific formulas, the actual package may differ materially from the estimate shown here.
It is also important to remember that severance practices vary by employer and by jurisdiction. Some organizations cap severance at a maximum number of weeks. Some round years of service up or down. Some pay unused vacation only where required, while others include it as a standard benefit. Some separation agreements use a flat number of weeks rather than weeks per year. If your situation touches local employment law, a collective bargaining agreement, or a negotiated release, use this estimate as a planning tool and confirm the details with the governing documents.
- The result is gross, not net. It does not subtract taxes or withholding.
- Salary is treated as annual base pay. If you enter the wrong time unit, the whole estimate shifts.
- Vacation is valued with a five-day week. Different accrual rules may require a separate check.
- Local law can override policy. Minimums, notice requirements, or caps may apply.
- Negotiated extras belong in the lump-sum field. Keep them separate from the weeks-per-year policy so you can see which part is driving the total.
Used the right way, a severance calculator is less about pretending the world is simple and more about making your assumptions visible. Once you can see the package broken into salary-based severance, vacation payout, and extra cash, you can ask better questions, compare scenarios fairly, and decide whether the number is merely plausible or actually appropriate for the situation in front of you.
Optional mini-game: Severance Policy Sprint
Want a quick feel for how sensitive severance packages are to policy changes? This optional canvas mini-game turns the same math into a fast review challenge. Each employee case slides toward sign-off. Your job is to adjust the weeks-per-year policy so the package lands inside the green fairness band before the review clock expires. It is short, replayable, and built to reinforce the biggest lesson from the calculator: small changes in policy can move a package by thousands.
Best score saved on this device: 0. Educational takeaway: the base severance term usually grows fastest when both salary and years of service are large.
