Understanding Your Christmas Bonus Entitlement

As we approach the end of the year, many employees are preparing to receive their Christmas bonuses, a right established by the Mexican Federal Labor Law (LFT). However, confusion may arise for those who have received a salary increase during the year. This guide aims to clarify how to calculate your Christmas bonus, considering any salary adjustments.

What is a Christmas Bonus?

The Christmas bonus, known as “aguinaldo” in Mexico, is a non-negotiable right for all workers. According to Article 87 of the LFT, it is at least 15 days’ worth of salary for those who have completed a full year with the same employer. For employees with less tenure, they receive a proportional amount based on their time worked.

Calculating Your Daily Salary

To determine your daily salary, divide your monthly income by 30 (the number of days in a month). This daily figure is then multiplied by 15 for private sector employees or 40 for public sector workers, as dictated by labor laws.

Salary Increase and Christmas Bonus Calculation

If you’ve received a salary increase, the Christmas bonus calculation should be based on your current, post-increase salary. This means that even if the raise was implemented before the bonus calculation, your new salary should be the basis for determining your bonus.

Example

Consider a worker in the State of Mexico earning the minimum wage, equivalent to 8,480.17 pesos monthly. Suppose they received a 50% salary increase in October, starting November with a new monthly salary of 12,720 pesos.

  • 12,720 (monthly salary) / 30 (days in a month): 424
  • 424 (daily salary) x 15 (days): 6,360 pesos (Christmas bonus)

Calculating Christmas Bonuses for Variable Salaries

While the standard calculation applies to employees with fixed salaries, the LFT also considers variable salaries. Article 89 refers to wages based on performance, such as piece-rate or commission payments. In these cases, the bonus calculation differs.

To determine the bonus amount, use the average of the worker’s regular earnings over the last 30 actual working days (or less, if applicable), as per Pluxee. This average daily salary serves as the base for applying the traditional formula, similar to the fixed-salary calculation.

The Importance of Timely Christmas Bonus Payment

Receiving your Christmas bonus on time and as required by law not only ensures compliance but also acts as a powerful motivator for employees, fostering engagement and commitment as the year draws to a close. This bonus contributes to improved worker performance and satisfaction, ultimately benefiting both employees and employers.
