How it works
Formula: Yearly pay = hourly rate × hours/week × weeks
Yearly pay = hourly rate × hours a week × paid weeks a year (52 if your time off is paid). A month is a twelfth of the year: at 40 hours a week, a month has 40 × 52 ÷ 12 ≈ 173.33 hours on average, not 40 × 4 = 160. The other way round, the hourly rate is the yearly pay divided by the hours worked in the year. All amounts are gross.
Worked examples
15 an hour, 40 hours a week
31,200.00 a year, or 2,600.00 a month, gross.
45,000 a year, 40 hours a week
21.63 an hour, gross.
40 hours a week: how many hours a month?
40 × 52 ÷ 12 = 173.33 hours on average.
Common mistakes
Counting 4 weeks a month: 40 h × 4 = 160 h.
A month has 52 ÷ 12 ≈ 4.33 weeks on average: 173.33 h.
Mixing up gross and take-home pay.
The tool gives gross pay: taxes and deductions are not taken off.
Counting 52 weeks when some time off is unpaid.
With 48 paid weeks instead of 52, yearly pay drops by 7.7%.
What the calculation leaves out
- Gross amounts: taxes, deductions and benefits are not included.
- Overtime, bonuses and shift premiums are not included.
