Salary conversion formulas
Annual salary = Hourly rate × Hours per week × Weeks per year
Monthly salary = Annual salary / 12
Hourly rate = Annual salary / (Hours per week × Weeks per year)
At €20/hour, 35 hours per week and 52 weeks, the annual equivalent is €36,400 and the monthly average is about €3,033.33.
Why 151.67 hours per month at 35 hours per week?
35 × 52 = 1,820 hours/year
1,820 / 12 ≈ 151.67 hours/month
This is an average monthly time basis, not a statement that every calendar month contains the same working hours.
Time conversion is not gross-to-net conversion
Changing the salary period does not calculate payroll deductions. Contributions, taxes, bonuses, overtime and individual payroll rules are separate issues.
For financing simulations, use the loan calculator. To model savings growth, use the compound interest calculator.
Key point
Use the same weekly hours and annual-week assumption when comparing two compensation packages.
