How the yearly salary is calculated
Multiply the hourly wage by the hours you work in a week, then by the number of weeks you are paid. Full-time work is usually counted as 40 hours and 52 weeks, which is where the 2,080 hours come from.
$21 × 40 hours × 52 weeks = $43,680 per year
Hourly workers are only paid for hours actually worked, so unpaid holidays, sick days and slow weeks reduce the real annual figure. Two unpaid weeks a year lower it to $42,000.
