How this works
Overtime is paid at your hourly rate plus a premium that depends on the day and on your total hours in the year. This calculator derives the hourly rate from your monthly base salary and applies the percentages set in article 268 of the Labour Code. It is a gross, estimated figure — no substitute for your payslip.

We work out your hourly rate
The hourly rate starts from your monthly base salary: multiply by 12 (the 12 salary months) and divide by 52 weeks times your weekly hours. At 40 hours/week, that is the same as dividing by 173.33 hours/month.

We apply the right premium
On a workday, the 1st hour is worth +25% and the following hours +37.5%. On a rest day (weekly or complementary) or public holiday, each hour is worth +50%. These are the figures in article 268 of the Labour Code.

We check the 100-hour threshold
Above 100 overtime hours per year at the same employer, the premiums double: 50% and 75% on a workday, 100% on a rest day or holiday. The doubling applies only to the hours beyond the yearly 100 — tick the box to price those hours.
Frequently asked
What percentages does the law set for overtime?
Under article 268 of the Labour Code, up to 100 overtime hours a year: on a workday, +25% on the first hour or fraction and +37.5% on the following hours; on a rest day or holiday, +50% per hour. Above 100 hours/year, the premiums double to 50% / 75% (workday) and 100% (rest day/holiday).
How is the value of one normal hour worked out?
The hourly rate is (monthly pay × 12) ÷ (52 × normal weekly working hours), the formula in article 271 of the Labour Code. At 40 hours/week, that divides by 173.33 hours per month. Use base salary, without allowances.
Does the meal allowance count?
No. The hourly rate is based on base pay (plus seniority bonuses, if any). Meal, holiday and Christmas allowances are left out of the formula. This calculator uses only the base salary you enter.
Is overtime taxed and subject to social security?
Yes. The figure this tool shows is gross. Income tax (IRS) and the 11% social-security deduction apply, as with the rest of your pay. There are reduced-IRS rules for part of overtime pay — check your case with the tax authority or your accountant.
Can my employer give time off instead of money?
Compensatory rest can apply in certain conditions set by law or by collective bargaining agreement. The exact rules depend on your sector. For your case, check the applicable collective agreement or contact the labour authority (ACT).
DISCLAIMER
Estimate based on the premium percentages in article 268 of the Labour Code (Law 7/2009, as amended) and the hourly-rate formula in article 271. The figure shown is gross, before income tax and social security, and uses only the base salary you enter. Collective agreements may set different terms.
