Time and a half calculator
Your Overtime Rate
$30.00
$20.00/hr × 1.5 = $30.00 per overtime hour
Quick answer: time and a half is your regular hourly rate × 1.5. At $20/hour the overtime rate is $30/hour, so 8 overtime hours pay $240. Under the US FLSA, non-exempt employees must get 1.5× for hours worked over 40 in a workweek.
How to calculate time and a half
- Find your regular rate. Hourly: your wage. Salaried: annual salary ÷ 52 ÷ hours per week (usually 40).
- Multiply by 1.5 to get the overtime rate. $18/hr → $27/hr.
- Count overtime hours. In the US, federal overtime starts after 40 hours in a single workweek.
- Multiply the overtime rate by overtime hours, then add regular pay.
The formula the calculator uses:
Total pay = (regular hours × rate) + (overtime hours × rate × 1.5)

Who actually gets time and a half?
- US: non-exempt (usually hourly) employees, for hours over 40 in a workweek. Some states — California, Colorado, Alaska — also trigger overtime after 8 or 12 hours in a day.
- Exempt salaried workers generally get no overtime, though many employers still pay it as policy.
- UK: there is no automatic 1.5× rule. Overtime pay depends on your contract. Total pay must still average at least the National Minimum Wage for the hours worked.
- Holiday pay: time and a half on public holidays is company policy or a union agreement in the US — not federal law.
Common mistakes
- Paying overtime on the base wage when bonuses or shift differentials should be included in the "regular rate".
- Averaging hours across two weeks — the FLSA workweek is fixed and separate.
- Forgetting that in California, daily overtime over 8 hours is 1.5× and over 12 hours is 2×.
Frequently asked questions
What is time and a half on $20 an hour?
$30 per hour. 8 hours of overtime at that rate is $240, on top of your regular pay.
Is time and a half 1.5 or 150%?
They are the same thing: 1.5× your normal rate, i.e. a 50% premium on top of straight time.
What is "double time and a half"?
There is no federal 2.5× rate. People usually mean either double time (2×) or time and a half (1.5×) — pick the multiplier that matches your contract in the tool above.
How do I work out time and a half from a salary?
Convert to an hourly rate first: annual salary ÷ 52 ÷ hours per week, then ×1.5. This calculator does that conversion for you when you choose "A salary".
Does overtime get taxed more?
No — overtime is taxed at your normal rate. It can look like more was withheld because payroll software annualises a bigger paycheque.
