How the yearly figure is built

  • $407 per week × 52 weeks = $21,181 per year.
  • Monthly pay is the annual salary divided by 12, not four weekly paychecks — that is why some months look larger.
  • A biweekly paycheck is smaller than a semi-monthly one, but you receive 26 of them a year instead of 24.
