Before you accept the number
- Overtime is normally paid at 1.5× the base rate, so the same job at 45 hours a week is worth $954.81 for those extra hours.
- Unpaid lunch breaks are not part of a 40-hour week: a 30-minute break every day brings the paid year down by roughly 4%.
- The annual figure above is gross pay. Federal income tax, FICA and any state tax come out of it before the money reaches your account.
