📊 Working hours & conversion details
Understanding your hourly wage is crucial when comparing job offers, checking if your compensation complies with the SMI minimum limits, or determining your base rate for overtime pay. In Spain, calculations relating monthly salaries to hours worked use specific formulas that account for extra payments and vacation weeks.
📐 Formula: Converting monthly salary to hourly rate
To calculate your hourly wage from a gross monthly salary, use the standard conversion factor of 4.33 weeks per month (52 weeks divided by 12 months):
Hourly rate = Gross monthly salary / (Weekly hours * 4.33)
This is more accurate than dividing by 4, since months are longer than 28 days.

⚠️ Common mistakes when calculating hourly wages
- Dividing by 160 hours per month: A full-time month does not equal 160 hours (4 weeks × 40 hours), but rather 173.33 hours on average (4.33 weeks × 40 hours). Dividing by 160 inflates your hourly rate.
- Ignoring the 14-payment structure: If your annual salary is split into 14 paychecks, you must account for the two extra payments (summer and winter) before dividing your monthly check by your hours.
- Forgetting annual vacation days: Vacations and public holidays reduce your actual working hours. Dividing your annual salary by your active working hours yields a higher effective hourly wage.
❓ Frequently Asked Questions (FAQ)
For a standard 40-hour week, a full working month has an average of 173.33 hours. This is calculated by multiplying 40 weekly hours by 4.33 weeks per month.
A calendar year has 52 weeks. Dividing 52 weeks by 12 months yields 4.333 weeks per month. This is more accurate than dividing by 4, since most months contain 30 or 31 days.
If your annual salary is paid in 14 payments, you must convert your monthly paycheck to its 12-payment equivalent (monthly paycheck × 14 / 12) before dividing by monthly hours, or calculate directly from your annual gross salary.
Yes. The annual SMI includes all mandatory extra payments. Thus, the casual worker rate of €13.45/hour has all extra payments and vacations prorated in the price.
A reduction in working hours does not change your hourly rate. If you reduce your hours (e.g. for childcare), your gross monthly salary decreases proportionally, keeping your hourly wage identical.
You can search for the official wage tables of your collective agreement in the BOE. Compare your base annual salary and mandatory bonuses with the agreement's minimum, and divide by the specified annual hours.
