How a Mexico severance pay calculator works
A Mexico severance pay calculator helps employees, HR teams, payroll professionals, founders, and legal advisors estimate what may be owed when an employment relationship ends. In practice, many people use the word severance to describe every final payment, but in Mexico it is important to separate indemnizacion constitucional from finiquito. A true Mexico severance pay calculator should therefore show more than one category. It should estimate dismissal compensation, but it should also account for accrued benefits such as proportional aguinaldo, unused vacation, and the related vacation premium.
The calculator above is built for exactly that purpose. It starts with monthly salary, converts that amount to a daily rate, and then applies a commonly used legal framework for educational estimation. For an unjustified dismissal scenario, the most recognized components are: 3 months of salary, 20 days of salary per year of service, and seniority premium. On top of that, many final settlements also include proportional statutory benefits earned but not yet paid. Those benefits can have a meaningful impact on the final number, especially if the employee is leaving late in the year or has significant vacation time remaining.
Even so, a calculator should never be treated as a substitute for legal advice. Real cases often depend on the exact contract language, whether the salary should be treated as an integrated salary, commission structures, union rules, litigation outcomes, employer records, and whether a settlement agreement was signed. For that reason, this page is best used as an informed planning tool, not as a final legal opinion.
Main severance components in Mexico
1. Three months of salary
In a standard unjustified dismissal example, the employee may claim a constitutional severance equivalent to 3 months of salary. This is the first major component many people think of when they search for a Mexico severance pay calculator. If a worker earns MXN 30,000 per month, then this portion alone would be MXN 90,000.
2. Twenty days of salary per year of service
Another frequently modeled component is 20 days of salary for each year of service. In practical calculations, fractional service may also be estimated on a prorated basis for planning. For example, 5.5 years of service at a daily salary of MXN 1,000 would produce 110 days of pay, or MXN 110,000.
3. Seniority premium
Seniority premium, often called prima de antiguedad, is commonly estimated as 12 days of salary per year of service, subject to a salary cap tied to twice the applicable minimum wage. This is one of the most misunderstood parts of a Mexico severance pay calculator because the employee’s actual daily salary is not always the number used in the formula. If the salary is above the legal cap, the premium is calculated using the capped amount instead. That is why this calculator asks you to choose the reference year and region.
4. Proportional aguinaldo
Aguinaldo is the year end statutory bonus, with a legal minimum of 15 days of salary for many employees. If the worker leaves before year end, a proportional amount is generally calculated based on the time worked during the year. A good calculator allows you to enter months worked in the current year so you can estimate this amount instead of ignoring it.
5. Unused vacation and vacation premium
Mexican final settlements often include payment for unused vacation days, plus a vacation premium. The premium is commonly set at 25 percent or more depending on the employment terms. Employees often focus on the larger severance line items and miss this category, but it can still add a useful amount to the final total.
When severance is different from finiquito
One of the most important concepts for using a Mexico severance pay calculator correctly is understanding the difference between severance and settlement. In simple terms:
- Severance usually refers to compensation linked to an unjustified dismissal or a negotiated separation package.
- Finiquito usually refers to amounts earned but not yet paid, such as wages due, proportional aguinaldo, vacation, vacation premium, and other accrued benefits.
If someone resigns voluntarily, they typically do not receive the full unjustified dismissal package. However, they may still receive finiquito items. In some cases, seniority premium may become relevant on resignation after a sufficiently long period of service. That is why the calculator includes different exit types. This feature helps users avoid the common mistake of applying a full dismissal formula to every departure.
Reference data: minimum wage figures often used in planning
The cap for seniority premium depends on the applicable minimum wage. The figures below are useful planning references commonly cited from Mexico’s wage authority. They matter because a high salary employee will often see the seniority premium calculated on a capped daily amount, not on the full daily salary.
| Year | General Zone Daily Minimum Wage | Northern Border Zone Daily Minimum Wage | Double Wage Cap Used for Seniority Premium |
|---|---|---|---|
| 2024 | MXN 248.93 | MXN 374.89 | General: MXN 497.86, Border: MXN 749.78 |
| 2025 | MXN 278.80 | MXN 419.88 | General: MXN 557.60, Border: MXN 839.76 |
For high earning employees, these cap numbers can materially reduce the estimated seniority premium compared with a naive spreadsheet that simply multiplies 12 days by the full daily salary. That difference is one reason why a purpose built Mexico severance pay calculator is more reliable than a quick mental estimate.
Comparison table: common payment treatment by exit type
| Payment Component | Unjustified Dismissal | Voluntary Resignation | Mutual Agreement |
|---|---|---|---|
| 3 months of salary | Commonly claimed or negotiated | Usually not applicable | Depends on the agreement |
| 20 days per year of service | Common estimate in dismissal analysis | Usually not applicable | Depends on the agreement |
| Seniority premium | Often relevant, with wage cap rules | Often only after long service, commonly 15+ years in planning discussions | Depends on facts and negotiated terms |
| Proportional aguinaldo | Usually included in finiquito | Usually included in finiquito | Usually included in finiquito |
| Unused vacation + vacation premium | Usually included | Usually included | Usually included |
Step by step example using a Mexico severance pay calculator
Assume an employee earns MXN 30,000 per month, has worked 5 years and 6 months, has completed 8 months in the current year, has 10 unused vacation days, and receives a 25 percent vacation premium. Their daily salary would be MXN 1,000 using the simple planning conversion of monthly salary divided by 30.
- Three months of salary: MXN 90,000.
- 20 days per year: 20 x 5.5 x MXN 1,000 = MXN 110,000.
- Seniority premium: 12 x 5.5 x capped daily salary. If the general 2025 cap applies, the capped salary would be MXN 557.60, not MXN 1,000. That gives MXN 36,801.60.
- Proportional aguinaldo: 15 days x MXN 1,000 x 8/12 = MXN 10,000.
- Unused vacation: 10 x MXN 1,000 = MXN 10,000.
- Vacation premium: MXN 10,000 x 25% = MXN 2,500.
Under those assumptions, the estimated total would be MXN 259,301.60. A chart based calculator is useful here because it helps users see which piece drives the final amount. In this example, the 20 days per year and the 3 month indemnity are the dominant categories, while vacation related items are smaller but still meaningful.
Important assumptions and limitations
Integrated salary can matter
In some disputes, the relevant salary is not just base salary. Bonuses, commissions, fixed allowances, and recurring benefits may affect the integrated salary analysis. If your actual legal case depends on integrated salary, a simple monthly salary field may understate or overstate the final amount.
Years of service can include fractions
The calculator prorates additional months of service for planning. That creates a smoother estimate and can be helpful in negotiation prep. Still, actual legal treatment can depend on the exact claim, documents, and tribunal analysis.
Not every exit triggers the same rights
Employees often search for a Mexico severance pay calculator after resigning, only to discover that resignation usually leads to finiquito, not the full unjustified dismissal package. Employers also use calculators incorrectly when they assume that a negotiated termination can be priced exactly like a pure statutory dismissal. The law and the settlement document both matter.
Best practices for employees using this calculator
- Gather pay stubs and your employment contract before estimating anything.
- Confirm whether your monthly salary is base salary or a broader integrated compensation figure.
- Check your vacation balance and the premium percentage in your contract or collective rules.
- Record the exact months worked in the current calendar year to estimate proportional aguinaldo accurately.
- Review whether your case is resignation, dismissal, or a mutual agreement because that classification changes the outcome significantly.
Best practices for employers and HR teams
- Use a documented methodology so all terminations are reviewed consistently.
- Separate mandatory statutory items from discretionary settlement offers.
- Check the applicable minimum wage year and region before calculating seniority premium.
- Maintain clear accrual records for vacation, bonuses, and salary changes.
- Have counsel review higher value exits or disputed terminations.

Final thoughts on using a Mexico severance pay calculator
A well designed Mexico severance pay calculator should do more than multiply salary by a single factor. It should reflect the legal logic behind dismissal compensation, distinguish severance from finiquito, account for vacation and aguinaldo, and apply a proper cap to seniority premium when necessary. That is the difference between a rough guess and a serious planning tool.
The calculator on this page is designed to be transparent. You can change the exit type, salary, service period, current year service, unused vacation, vacation premium, and minimum wage reference to create a more realistic estimate. The resulting chart also makes it easier to review the structure of the final number before speaking with HR or legal counsel. Used properly, it can save time, reduce confusion, and create a stronger basis for informed negotiations.
