Time and a half for $21 an hour is $31.50 per overtime hour. Federal law owes overtime on hours past 40 in a workweek, not on long days, so a 50-hour week at $21 pays $1,155 — $840 at the regular rate plus $315 for 10 overtime hours.
Overtime rates for $21 an hour
| Rate | Per hour | When it applies |
|---|---|---|
| Regular 1x | $21.00 | Up to 40 hours in the workweek |
| Time and a half 1.5x | $31.50 | Every hour past 40, under federal law |
| Double time 2x | $42.00 | Not federal — some states and contracts only |
The multiplier applies to the regular rate, which is not always the base wage. Non-discretionary bonuses, shift differentials, commissions and production incentives all fold into it, so a week that includes any of them has a regular rate above $21.00 and an overtime rate above $31.50.
This is one of the more common payroll errors, and it is worth checking on a payslip: overtime computed on the base wage alone quietly underpays anyone earning a differential. Discretionary gifts and true bonuses the employer is not obliged to pay are the exception.
Five overtime hours a week at $31.50 adds $8,190 over 52 paid weeks; ten hours a week adds $16,380. To earn an extra $10,000 in a year at this rate takes about 6.1 overtime hours a week, every week.
Where $21 an hour sits nationally
$21 an hour is 67% of the US median full-time wage, which puts it below the middle of the distribution. The median is published as a weekly figure — $1,251 a week for full-time workers — and reads as roughly $31.28 an hour over a 40-hour week.
The national median flattens a lot of variation. The same rate is a strong wage in one metro and a tight one in another, and the occupation matters as much as the geography. Treat it as a position on a scale, not a verdict.
How $21 an hour compares
- It is 2.9x the federal minimum wage of $7.25 an hour, which is $28,600 more a year at the same hours.
- It is below the US median, at 67% of the median full-time wage.
- It clears every state minimum wage, including Washington’s $17.13, the highest in the country.
Federal minimum wage $7.25, in effect since July 2009 (U.S. Department of Labor, Wage and Hour Division). Median earnings from U.S. Bureau of Labor Statistics, Usual Weekly Earnings, second quarter 2026 — median usual weekly earnings of full-time wage and salary workers. The hourly equivalent of $31.28 is that weekly figure over 40 hours, which is a derivation rather than a separately published median hourly wage. Highest state minimum: Washington, effective 1 January 2026.
How this is worked out
The default assumes 40 hours a week over 52 weeks, which is 2,080 paid hours a year. Yearly pay is the hourly rate multiplied by those hours; monthly is the year split twelve ways.
Biweekly and semi-monthly are not the same thing. Biweekly means every two weeks, which is 26 pay periods a year. Semi-monthly means twice a month, which is 24. That is why those two rows differ above, and why two months of the year carry a third biweekly cheque.
Every figure here is gross — before income tax, payroll tax and deductions.
Common questions
How much is $21 an hour a month?
$21 an hour is $3,640 a month before tax, at 40 hours a week. That is the yearly total of $43,680 divided by twelve, not four weekly cheques — a month averages about 4.33 weeks, so four weeks of pay at $840 comes to less than a month's share.
What is $21 an hour after taxes?
Every figure on this page is gross, before income tax, payroll tax and deductions. Take-home from $43,680 depends on your state, filing status, pre-tax deductions and local taxes, and those move the result by thousands — so no single after-tax number would be true for most readers. Social Security and Medicare alone take 7.65% of wages from an employee before any income tax applies.
Is $21 an hour above the US median wage?
$21 an hour is 67% of the median full-time wage, so it sits below the middle. The median is published weekly by the Bureau of Labor Statistics and read here over a 40-hour week; it flattens a lot of variation between occupations and metros.
How much is $21 an hour biweekly?
$1,680 every two weeks, which is 26 pay periods a year. Twice a month is not the same thing — that is 24 periods and works out to $1,820 a cheque. Two months of the year carry a third biweekly payment, which is why the two figures differ.
Is $21 an hour the same as a $43,680 salary?
In gross pay, yes, at 40 hours a week. In practice they behave differently: an hourly worker is generally owed time and a half past 40 hours in a week, while a salaried exempt worker is not. A $43,680 salary that expects fifty-hour weeks is a lower effective rate than $21 an hour.
