# Calculator for hours to reorganize with the reduced working week

Short answer

Enter how many people you have and how many hours they work today. You will see how many hours per week remain to be covered when the maximum workday drops.

## How to do the math by hand

With 10 people working 48 hours and a maximum of 46, that is 2 hours per person: 20 hours per week to cover.

## What to do with that number

- Reorganizing shifts.
- Hiring relief staff.
- Paying them as overtime, within the cap.

## Why everything starts with the working-time record

Almost every labor calculation starts from the same data point: how many hours and which days each person worked. If that data is uncertain, so is everything else.

- **Overtime:** it is paid according to the hours of each week.
- **Sunday premium and rest days worked:** they depend on which days were worked.
- **Aguinaldo and profit sharing:** they use the days worked in the year.
- **Labor lawsuits:** the company must prove the working time.

Since 2026, the Federal Labor Law requires that record to be electronic, per person, with start and end time.

## Common mistakes

- Entering net pay instead of gross.
- Not changing the shift type when it is a night or mixed shift.
- Treating the result as if it were the payslip.
- Forgetting that the UMA and the minimum wage change every year.
- Not noting what data the calculation was made with.

## What to do now

1. Confirm the current value for the year.
2. Have each person's daily salary at hand.
3. Check the days and hours worked in your record.
4. Do the math and keep it.
5. Validate it with your accountant.

## Frequently asked questions

### Is it a cost?

It is a volume of hours. The cost depends on how you decide to cover them.

### Do these values change every year?

Yes. The UMA is updated every February 1 and the minimum wage every January 1. Always confirm the current value.

### Are the amounts gross or net?

Gross. They do not account for taxes or social security contributions.

### Can I use this for my payroll?

It works as a reference. Your accountant should do or validate the payroll calculation.

### Where does the data come from?

From the Federal Labor Law and from the official values published by INEGI and the National Minimum Wage Commission.
