Estimates for personal planning — not tax, legal, or payroll advice. Every number above is gross pay unless a line says otherwise; the formula, its boundaries, and its test cases are published below.
How it works
rate₁.₅ = $20.00 × 1.5 = $30.00 /hr
pay = $30.00 × 8.0 h = $240.00
What time and a half means
“Time and a half” is 150% of your regular hourly rate. Federally it is required for hours over 40 in a workweek (29 CFR §778.107); employers may also offer it for holidays, weekends, or on-call shifts by policy or contract.
Holiday pay is not federally required
A common surprise: the FLSA does not require premium pay for working holidays or weekends as such — those premiums are a matter of employer policy or union agreement (DOL, Holiday Pay). If your handbook says holidays pay time and a half, this calculator gives you the exact number.
Common time-and-a-half rates
| Base rate | Time & a half | Double time |
|---|---|---|
| $12.00/hr | $18.00 | $24.00 |
| $15.00/hr | $22.50 | $30.00 |
| $16.50/hr | $24.75 | $33.00 |
| $18.00/hr | $27.00 | $36.00 |
| $20.00/hr | $30.00 | $40.00 |
| $22.00/hr | $33.00 | $44.00 |
| $25.00/hr | $37.50 | $50.00 |
| $30.00/hr | $45.00 | $60.00 |
| $35.00/hr | $52.50 | $70.00 |
Comp time is not a private-sector option
Public-sector employers may, under agreement, give compensatory time off at 1.5 hours per overtime hour instead of cash. Private employers generally may not — if you worked the overtime, it gets paid in the period it was earned (DOL Fact Sheet 7). “Take a day off next month instead” is not a lawful substitute at a private company.
Time and a half on a partial hour
Overtime rarely lands on whole hours. Convert the minutes first, then multiply — 6 hours 20 minutes at a $30.00 overtime rate is 6.33 h × $30.00 = $189.90, not “6.20 × 30”. That difference is $3.90 on a single shift and compounds every week. Convert your minutes →
