See what's truly left after commute time, lunch and work-related costs.
The "real" hourly wage is not just net pay divided by contract hours. It includes all the extra time and money your job costs you: commute, unpaid overtime, eating out at work, specialized clothing, training. What's left is what you actually earn per hour of life invested.
Looking at the real hourly wage helps you decide better: Is the expensive commute worth €200 more in pay? Is the job offer with one extra hour of travel actually better? Does remote work make you wealthier even at the same gross? Often the real calculation shows that a few hundred euros gross more get fully eaten by the added burden.
