The rule behind the numbers
Federal law pays 1.5 times your $21 rate, $31.50, for every hour past 40 in a workweek. Hours over 8 in a day earn nothing extra unless you're in California, Alaska, Nevada or Colorado, which the calculator above handles when you pick the state. Overtime is figured per week, never averaged across a pay period.
The tax side
The last column is what the 2025 law lets you deduct if you worked that much overtime every week of the year: only the $10.50 premium per hour counts, capped at $12,500. Your employer still withholds normally, so the saving shows up as a refund. The no-tax-on-overtime calculator handles the cap and the income phase-out, and the time and a half calculator gives the rate alone.
