Overtime calculator
Short answer
Choose the year, your daily salary and the overtime hours for the week. The calculator separates the double-time hours from the triple-time hours and gives you the total pay.
How to do the math by hand
Take a salary of $400 per day on a day shift. The ordinary hour is worth 400 ÷ 8 = $50. In 2027, with 11 overtime hours in the week, the first 9 are paid at double time (9 × $100 = $900) and the remaining 2 at triple time (2 × $150 = $300). Total: $1,200.
How it works
- Divide the daily salary by the hours in the workday to get the value of the hour.
- Pays double time up to the weekly cap for the year.
- Pays triple time for up to 4 more hours.
| Year | Maximum working hours | Double-time overtime | Triple-time overtime |
|---|---|---|---|
| 2026 | 48 h | 9 h | 4 h |
| 2027 | 46 h | 9 h | 4 h |
| 2028 | 44 h | 10 h | 4 h |
| 2029 | 42 h | 11 h | 4 h |
| 2030 | 40 h | 12 h | 4 h |

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

Frequently asked questions
Why does it stop at a certain number?
Because the law does not allow more overtime than the cap for the year plus 4.
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.
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.
