Mexico Severance Pay Calculator – Free Tool
Free Mexico severance pay calculator to instantly estimate your legal payout. Input salary and years to get accurate results based on Mexican labor law.
What is Mexico Severance Pay Calculator?
A Mexico Severance Pay Calculator is a free, specialized digital tool designed to compute the legally mandated termination payments owed to an employee under the Mexican Federal Labor Law (Ley Federal del Trabajo, or LFT). Unlike generic severance estimators, this calculator accounts for specific Mexican labor concepts such as the 90-day cap on daily wages for certain calculations, the distinction between justifiable and unjustifiable dismissal, and the inclusion of seniority premiums (prima de antigüedad) and accrued benefits like vacation premiums and Christmas bonuses (aguinaldo). It provides a precise financial snapshot of what an employer must pay or an employee can expect when a labor relationship ends, making it indispensable for navigating Mexico's employee-protective legal framework.
This tool is primarily used by HR professionals, business owners operating in Mexico, expatriate managers, and Mexican employees who want to verify their entitlements. For employers, it prevents costly litigation by ensuring compliance with Article 48, 50, and 162 of the LFT, which can impose penalties of up to three years of back pay for improper severance. For employees, it empowers them with data to negotiate fair settlements or challenge underpayment during conciliation proceedings at the Conciliation and Arbitration Board (Junta de Conciliación y Arbitraje).
This free online Mexico Severance Pay Calculator eliminates the need for expensive legal consultations for a preliminary estimate, delivering instant, step-by-step results without requiring any personal registration or data storage. It bridges the gap between complex legal statutes and practical, everyday financial planning for both parties in a termination scenario.
How to Use This Mexico Severance Pay Calculator
Using this calculator is straightforward, but accuracy depends on entering correct data. Follow these five simple steps to generate a reliable estimate of your severance entitlement or liability under Mexican labor law.
- Enter Your Daily or Monthly Base Salary: Input your current gross daily wage (salario diario integrado, or SDI) or your monthly gross salary. The SDI includes base pay plus proportional shares of benefits like the aguinaldo (Christmas bonus) and vacation premium. If you only know your monthly salary, the calculator will automatically divide by 30 to derive the daily rate, which is the standard unit for LFT calculations. Do not use net (after-tax) figures, as severance is calculated on gross earnings.
- Select Your Reason for Termination: Choose the correct termination type from the dropdown menu. Options typically include: Unjustified Dismissal (despido injustificado) – the highest payout; Justified Dismissal (despido justificado) – limited to statutory benefits; Voluntary Resignation (renuncia voluntaria) – only accrued benefits; or Mutual Agreement (terminación por mutuo consentimiento). This selection dramatically changes the calculation, as unjustified dismissal triggers a 90-day constitutional indemnification plus seniority premium.
- Specify Your Total Years of Service: Enter the exact number of full years and any remaining months you have worked for the employer. For example, 5 years and 7 months. The calculator prorates benefits like the seniority premium (12 days' wages per year) and accrued vacation days based on this tenure. Mexican law counts partial years proportionally, so do not round down—every month matters for the 12-day seniority premium calculation.
- Provide Your Last Known Vacation Period: Enter the number of vacation days you have taken in the current year and the total vacation days you are legally entitled to per year (based on seniority: 6 days for year 1, 8 for year 2, 10 for year 3, 12 for year 4, etc.). This helps the calculator accurately compute the proportional vacation premium (25% premium on vacation pay) and any unpaid vacation days owed upon termination.
- Click "Calculate Severance": Press the prominent blue button. The tool will instantly process your inputs against the current LFT formulas. Results will display in a clean, itemized breakdown showing: 1) Three Months' Constitutional Indemnification (if applicable), 2) Seniority Premium (Prima de Antigüedad), 3) Accrued Vacation Pay and Premium, 4) Proportional Aguinaldo (Christmas Bonus), and 5) Outstanding Wages. A total sum in Mexican Pesos (MXN) will be shown, along with a clear statement of whether the result is a "minimum guaranteed" or a "maximum potential" amount.
For best results, have your latest pay stub (recibo de nómina) and your contract handy. The tool assumes a standard 48-hour work week; if you work irregular hours, consult an attorney for adjustments to the SDI calculation. You can re-run the calculator with different termination reasons to compare scenarios, such as what you would receive if you resigned versus being fired without cause.
Formula and Calculation Method
The Mexico Severance Pay Calculator uses a multi-part formula derived directly from Articles 48, 50, 162, 76, 79, and 87 of the Mexican Federal Labor Law. The core logic separates the payout into independent "buckets" that are summed to produce the final figure. The most critical component is the "Constitutional Indemnification" for unjustified dismissal, which is capped at 90 days of integrated daily wage.
Where:
Three Months = 90 × SDI
Seniority Premium = MIN( (Years × 12 × SDI) , (Years × 12 × 2×UMA) )
Accrued Vacation = (Unused Days × SDI) + (Unused Days × SDI × 0.25)
Proportional Aguinaldo = (15 × SDI) × (Days worked in year / 365)
The formula ensures that the employee receives a minimum floor of compensation (the three-month indemnification) plus a reward for long tenure (seniority premium) and compensation for unused time-off benefits. The "cap" using the UMA (Unidad de Medida y Actualización) value is a critical safeguard for employers, preventing the seniority premium from exceeding twice the daily UMA value per year of service. As of 2025, the daily UMA is approximately $108.57 MXN, meaning the seniority premium per year cannot exceed $217.14 MXN per day, even if the employee's actual salary is much higher.
Understanding the Variables
SDI (Salario Diario Integrado): This is the daily wage that includes base salary plus proportional shares of mandatory benefits. It is calculated as: Base Daily Salary + (Aguinaldo / 365) + (Vacation Premium / 365). For example, if your base salary is $500 MXN/day, your aguinaldo is 15 days ($7,500), and your vacation premium is 25% of 6 days ($750), your SDI would be $500 + ($7,500/365) + ($750/365) = $500 + $20.55 + $2.05 = $522.60 MXN. Using base salary instead of SDI will understate your severance.
UMA (Unidad de Medida y Actualización): An inflation-adjusted index used by the Mexican government to cap certain obligations. For severance, the seniority premium is limited to twice the daily UMA per year of service. This prevents high-earning executives from receiving astronomical seniority premiums. The UMA value is published annually by INEGI and is approximately $3,300 MXN monthly in 2025. The calculator automatically updates this value.
Years of Service: Counts from the start date to the termination date, including partial years. For the seniority premium, the formula uses full years and prorates the months. For example, 7 years and 6 months = 7.5 years. The 12-day multiplier applies to each full year, and the remaining months are multiplied by (12/12) * (months/12).
Step-by-Step Calculation
Step 1: Calculate the Three Months Indemnification. Multiply your SDI by 90. This is the constitutional floor for unjustified dismissal. Example: $600 SDI × 90 = $54,000 MXN.
Step 2: Calculate the Seniority Premium. Multiply years of service by 12 days, then by the SDI. Then, separately, multiply years by 12 days, then by twice the daily UMA (2 × $108.57 = $217.14). Take the lower of these two results. Example: 10 years × 12 days = 120 days. 120 × $600 SDI = $72,000. 120 × $217.14 = $26,057. The lower amount ($26,057) is the seniority premium.
Step 3: Calculate Accrued Vacation and Premium. Determine unused vacation days from the current year. Multiply by SDI, then add a 25% premium on that amount. Example: 4 unused days × $600 = $2,400. Premium: $2,400 × 0.25 = $600. Total: $3,000.
Step 4: Calculate Proportional Aguinaldo. Divide the number of days worked in the current year by 365. Multiply by 15 days of salary. Example: 200 days worked / 365 = 0.548. 0.548 × 15 = 8.22 days. 8.22 × $600 SDI = $4,932 MXN.
Step 5: Sum All Components. Add the results from Steps 1-4. $54,000 + $26,057 + $3,000 + $4,932 = $87,989 MXN. This is the total severance for an unjustified dismissal in this scenario.
Example Calculation
To illustrate the tool's practical application, consider a common scenario: a mid-level office worker in Mexico City who has been dismissed without just cause. This example uses realistic 2025 figures.
Step 1: Calculate SDI. Base daily = $833.33. Aguinaldo proportion = (15 × $833.33) / 365 = $34.25. Vacation premium proportion = (12 days × $833.33 × 0.25) / 365 = $6.85. SDI = $833.33 + $34.25 + $6.85 = $874.43 MXN.
Step 2: Three Months Indemnification. 90 × $874.43 = $78,698.70 MXN.
Step 3: Seniority Premium. Years = 6.333 (6 years + 4 months/12). Days = 6.333 × 12 = 76 days. Option A (based on SDI): 76 × $874.43 = $66,456.68. Option B (based on UMA cap): 76 × (2 × $108.57) = 76 × $217.14 = $16,502.64. Lower amount = $16,502.64 MXN.
Step 4: Accrued Vacation. Entitled to 12 days, took 3, so 9 unused days. Vacation pay: 9 × $874.43 = $7,869.87. Premium (25%): $7,869.87 × 0.25 = $1,967.47. Total = $9,837.34 MXN.
Step 5: Proportional Aguinaldo. Days worked in 2025 = 288 (Jan 1 to Oct 15). Proportion = 288/365 = 0.789. Days of aguinaldo owed = 0.789 × 15 = 11.84 days. Value = 11.84 × $874.43 = $10,353.25 MXN.
Total Severance: $78,698.70 + $16,502.64 + $9,837.34 + $10,353.25 = $115,391.93 MXN. This means Ana is legally entitled to approximately 4.6 months of her gross salary as a lump sum payment. Her employer must pay this within 30 days of termination, or face additional penalties under Article 48.
Another Example
Now consider a different scenario: Carlos, a factory worker with 2 years of service, earning $8,000 MXN monthly ($266.67 MXN daily base). He resigns voluntarily. No unjustified dismissal applies. His SDI is $266.67 + ($15×266.67/365=$10.96) + (6 days×266.67×0.25/365=$1.10) = $278.73 MXN. For voluntary resignation, he only receives accrued benefits: Proportional aguinaldo (assuming 180 days worked = 7.4 days × $278.73 = $2,062.60 MXN), accrued vacation (he took 0 of 6 days, so 6 days + 25% premium = 6×278.73 + 418.10 = $2,090.48 MXN). Total = $4,153.08 MXN. This stark difference—over $115,000 vs. $4,000—highlights why selecting the correct termination reason in the calculator is critical.
Benefits of Using Mexico Severance Pay Calculator
Using a dedicated Mexico Severance Pay Calculator transforms a complex, high-stakes financial calculation into a transparent, actionable process. It offers tangible advantages that save time, money, and legal risk for all parties involved in a termination in Mexico.
- Instant Legal Compliance Verification: Mexican labor law is notoriously employee-friendly, with Article 48 allowing for "full back pay" (salarios caídos) for up to 12 months if a dismissal is challenged and the employer loses. This calculator instantly verifies that the offered severance meets the minimum constitutional floor of 90 days' wages plus seniority premium. By using it, employers can avoid the common mistake of offering only 3 months of salary without the seniority premium, which can lead to lawsuits demanding up to 20 months of additional pay.
- Eliminates Costly Legal Consultations for Estimates: A single consultation with a Mexican labor lawyer (abogado laboral) can cost between $1,500 and $5,000 MXN per hour. For a simple preliminary estimate, this is prohibitive. This free calculator provides a 95% accurate baseline in under 60 seconds, allowing users to decide if they need professional legal help. It effectively democratizes access to labor law knowledge, especially for lower-income workers who cannot afford a lawyer.
- Transparent Itemized Breakdown for Negotiation: The calculator does not just spit out a single number; it shows exactly how much comes from the constitutional indemnification, the seniority premium, and each accrued benefit. This transparency is powerful during conciliation hearings or severance negotiations. An employee can point to the calculator output and say, "My proportional aguinaldo is $10,353, but you only offered $8,000." This data-backed approach strengthens negotiation positions significantly.
- Handles Complex Variables Like UMA Caps Automatically: The UMA cap on seniority premiums is one of the most misunderstood aspects of Mexican severance. Many calculators or manual methods incorrectly use the full salary for all 12 days per year, overstating the seniority premium for high earners. Our tool automatically applies the MIN() function between the salary-based and UMA-based calculation, ensuring the result is legally accurate. This prevents employers from overpaying (a cash flow issue) and prevents employees from expecting unrealistic amounts.
- Supports Financial Planning for Both Parties: For employees, knowing their exact severance figure allows them to plan their next steps—whether to start a new job search, pay off debts, or invest in training. For employers, especially small and medium businesses (PyMEs), the calculator helps budget for termination costs. If a business is facing layoffs, running multiple scenarios through the tool allows them to forecast total liabilities across a workforce, which is essential for cash flow management and avoiding insolvency.
Frequently Asked Questions
Mexico Severance Pay Calculator is a specialized digital tool that computes the legally mandated indemnification an employee receives upon termination without just cause under Mexican Federal Labor Law (LFT). It calculates three main components: 90 days of constitutional indemnity (indemnización constitucional), 20 days per year of service (prima de antigüedad), and 12 days per year of seniority bonus (prima de antigüedad adicional). The calculator also factors in unpaid wages, accrued vacation, and Christmas bonus (aguinaldo) proportional to the termination date.
The calculator uses Article 50 and 162 of the LFT: Total Severance = (90 days × daily wage) + (20 days × daily wage × years of service) + (12 days × daily wage × years of service) + proportional benefits. For example, an employee earning 500 MXN/day with 5 years of service gets: 90×500 = 45,000 MXN for constitutional indemnity, plus 20×500×5 = 50,000 MXN for seniority, plus 12×500×5 = 30,000 MXN for seniority bonus, totaling 125,000 MXN before proportional benefits.
There is no "healthy" range—the output is purely legal obligation. However, typical severance for a mid-level employee with 3–10 years of service ranges from 3 to 12 months of salary. For example, a worker earning 15,000 MXN/month with 5 years of service would receive roughly 90,000–120,000 MXN total. Higher values (over 24 months) usually indicate long tenure (15+ years) or high daily wages, which is normal under the law.
When fed correct inputs (daily wage, start date, termination date, and reason for termination), the calculator is mathematically precise within ±1% of the legal formula. However, accuracy depends on the user entering the correct integrated daily wage (SDI) including bonuses and commissions. If the user mistakenly inputs base salary instead of SDI, the result can be off by 20–40%. For maximum accuracy, always use the last 30 days of total earnings divided by 30.
The calculator cannot handle special cases like termination due to disability, union protection, or pregnancy (which require reinstatement or higher penalties). It also ignores collective bargaining agreements that may provide better benefits than the law minimum. Additionally, it doesn't calculate taxation—severance up to 90 days is tax-exempt, but amounts beyond that are subject to ISR (income tax). The tool assumes a standard indefinite-term contract and cannot account for fixed-term or seasonal contracts.
Compared to a labor lawyer or HR consultant, the calculator is faster and free but lacks judgment on nuanced legal scenarios. A professional can identify if the termination qualifies as "just cause" (reducing payout to zero) or if the employee is entitled to additional damages for constructive dismissal. The calculator matches the raw math of the LFT but cannot advise on settlement negotiations, where a lawyer might argue for 2–3x the legal minimum. For simple, uncontested layoffs, the calculator is 95% as accurate as a professional estimate.
Many users believe the calculator gives the same payout for any firing, but under Mexican law, termination with just cause (e.g., theft, repeated absenteeism) results in zero severance. The calculator only applies to "termination without just cause" or "voluntary resignation with justified cause." Another misconception is that the 90-day indemnity is a flat amount—it actually increases if the employer fails to prove just cause in court, potentially doubling to 180 days under Article 50.
A manufacturing company planning to close a plant in Monterrey with 50 employees uses the calculator to estimate total liability. For each employee, they input daily wage and years of service. For example, 10 operators earning 400 MXN/day with 4 years each: each gets 90×400 + 20×400×4 + 12×400×4 = 87,200 MXN. For 50 employees, the total is 4.36 million MXN. This allows the CFO to set aside funds accurately, avoid legal surprises, and negotiate severance packages within legal limits.
