Mexico aguinaldo calculator: what you are entitled to by law
The aguinaldo is a mandatory annual benefit in Mexico. The Federal Labor Law (LFT) gives workers the right to an annual aguinaldo of at least 15 days of salary, paid before December 20. This calculator estimates the aguinaldo for a full year worked.
With a monthly salary of $10,000 MXN, your daily pay is $333.33 (10,000 ÷ 30) and the full-year aguinaldo is $5,000 ((10,000 ÷ 30) × 15), due before December 20.
This calculator is an educational aid, not labor, tax or PROFEDET advice. For your specific case (commissions, contracts, variable pay), check with your employer, an accountant, or PROFEDET.
How is the aguinaldo calculated in Mexico?
First, get the daily pay. This calculator uses a fixed-monthly-salary convention: monthly salary ÷ 30 (LFT, article 89 divides weekly/monthly wages by 7/30 to get daily pay). Then multiply it by the 15 statutory days (LFT, article 87).
Daily pay = Monthly salary ÷ 30
Aguinaldo = Daily pay × 15
| Item | Detail | |---|---| | Statutory days | 15 days of salary | | Payment deadline | Before December 20 | | Salary base | Ordinary monthly salary (daily quota wage) | | Legal basis | LFT, articles 87 and 89 |
Does the aguinaldo trigger income tax (ISR)?
The aguinaldo is exempt from ISR up to a limit of 30 UMA. The amount above that may be subject to withholding. This calculator shows the gross amount and does not compute a net figure, because that depends on the current UMA and ISR rate.
Do you get aguinaldo if you worked less than a full year?
The LFT also recognizes a proportional aguinaldo based on time worked if you have not completed a year of service. This version calculates only the full-year aguinaldo (15 days), not the proportional amount.
Examples
Example with a monthly salary of $10,000
| Item | Calculation | Amount | |---|---|---| | Monthly salary | — | $10,000.00 | | Daily pay | 10,000 ÷ 30 | $333.33 | | Aguinaldo (15 days) | (10,000 ÷ 30) × 15 | $5,000.00 |
Example with a monthly salary of $8,000
| Item | Calculation | Amount | |---|---|---| | Daily pay | 8,000 ÷ 30 | $266.67 | | Aguinaldo (15 days) | (8,000 ÷ 30) × 15 | $4,000.00 |
The LFT (article 87) requires the annual aguinaldo to be paid before December 20. People who have not completed a year of service are entitled to the proportional amount.
The law requires at least 15 days of salary for each year of service (LFT, article 87).
If your employer does not pay the aguinaldo before December 20, you can contact the Procuraduría Federal de la Defensa del Trabajo (PROFEDET) for guidance and conciliation. This page does not provide legal advice.
No. The rules differ: Mexico gives 15 days of salary (LFT); Guatemala pays a full monthly salary; El Salvador uses a different calculation under its own law. This calculator is for Mexico.
