The Vacation Premium Calculation Error in Aspel NOI

Aspel NOI is one of Mexico’s most widely used payroll systems. A frequent problem users face is incorrect vacation premium and vacation days calculation, especially after the Federal Labor Law (LFT) reform effective January 2023.

Prerequisites

  • Aspel NOI version 10.0 or higher.
  • Administrator access to the system.
  • Updated seniority table with the 2023 LFT reform values.

Step-by-Step Solution

1. Update the Seniority Table

Navigate to: Configuration → Tables → Seniority (Vacations)

Years of serviceVacation days (LFT 2023)
112
214
316
418
520
6-722
8-924
10-1126

The minimum vacation premium is 25% of the salary for vacation days (Art. 80 LFT).

2. Verify the Employee Start Date

  1. Access: Employee Catalog.
  2. Verify the “Start Date” field is correct.

3. Verify the Vacation Premium Concept

  1. Access: Payroll Concepts Catalog.
  2. Locate “Vacation Premium” and verify it is active with the correct formula.

4. Recalculate the Payroll

Navigate to: Processes → Payroll Calculation and recalculate the affected period.


Prevention

  • Apply Aspel NOI updates immediately when available.
  • Back up the database before modifying configuration tables.
  • Verify the seniority table at the beginning of each fiscal year.
