Overtime Calculator

Calculate the value of your overtime and its impact on the DSR online and for free. Enter your salary and number of hours.

Informational simulation only. It does not replace an officially certified calculation or advice from an accountant or a lawyer.

What is the Overtime Calculator?

The Overtime Calculator is a tool designed to help CLT workers find out exactly how much they should be paid for hours worked beyond their normal working hours.

By law, common overtime must be paid with at least a 50% increase over the normal hourly rate. If overtime is worked on Sundays or holidays, the increase becomes 100%. Some collective agreements for specific categories (such as bank workers, metalworkers, etc.) may determine even higher percentages, such as 75% or 120%.

Our tool does all the boring calculations for you: it divides your salary by your monthly working hours (normally 220 hours) to find your normal hourly rate, applies the chosen increase percentage and multiplies it by the amount of overtime worked in the month.

Reflection on DSR (Paid Weekly Rest)

Those who work overtime are also entitled to receive an extra amount for their rest (Sundays and holidays), the so-called DSR Reflex. The exact DSR bill depends on how many working days and Sundays/holidays you had in the specific month.

To facilitate the simulation, our calculator uses the market standard rule (1/6, or approximately 16.66% of the total value of overtime) to estimate the value of your DSR, getting very close to the real value that will appear on your paycheck.

How to use the Calculator

  1. Gross Salary: Enter your salary recorded in your portfolio.
  2. Monthly Workday: The total workload for your month. The standard for those who work 44 hours a week is 220 hours a month.
  3. Qty. Overtime: How many more hours you worked in the month.
  4. Addition: Choose the percentage. Use 50% for weekdays/Saturdays and 100% for Sundays and holidays.

Frequently asked questions

How to calculate the amount of overtime?

Divide your salary by your monthly working hours (e.g. 220 hours) to find the normal hourly rate. Then, add the percentage of overtime (ex: 50%) and multiply by the hours worked.

What is 100% overtime?

It is the extra hour worked on Sundays or non-compensated holidays. It's worth twice your normal working hour.
