Where the monthly figure comes from
A year has 52 weeks and 12 months, so one month has 52 ÷ 12 = 4.33 weeks. 10 × 4.33 = 43.30 hours. Payroll often uses 4.33 or 4.35 (52.18 weeks ÷ 12, because a year has 365.25 days): 43.50 hours. Convert this schedule to pay with the hourly to salary calculator, or subtract vacation and holidays on working hours in a year.
