What Overtime Calculator does, with a checked example
Enter an hourly rate, regular hours, overtime hours, and optional double-time hours, and this tool returns regular pay, overtime pay at 1.5x, double-time pay at 2x, and a weekly gross total, then scales the week into biweekly and monthly gross-pay summaries. The math is plain multiplication on what you type. The thing people most often get wrong: overtime is measured per workweek - every hour over 40 in the employer's fixed seven-day workweek - not per day and not per pay period, so an under-40 week never cancels out an over-40 one.
Worked example
A concrete input and expected output from the current implementation.
Input
Hourly rate $20, 40 regular hours, 5 overtime hours, 2 double-time hours
->
Expected output
Regular pay $800.00 (40 x $20); overtime pay $150.00 (5 x $30, since $20 x 1.5 = $30); double-time pay $80.00 (2 x $40); weekly gross $1,030.00; biweekly $2,060.00; monthly $4,463.33
Each hour bucket is paid at its own rate - regular at $20, overtime at $30, double time at $40 - and the $1,030 weekly total is scaled by x2 for biweekly and x52/12 for monthly, assuming the same week repeats.
