Time and a Half Calculator
Two inputs — your hourly rate and your overtime hours — and you get your 1.5× rate and total overtime pay. Need the whole week? The full timesheet grid is one click away.
The math, in one line
“Time and a half” means each overtime hour pays your normal hour plus half of it again:
overtime pay = hourly rate × 1.5 × overtime hours
In the US this is the federal minimum for non-exempt employees once a workweek passes 40 hours. The next tier up is double time (2×), which only some states require — California being the main one, after 12 hours in a single day. If that's your situation, the California overtime calculator splits all three tiers for you.
Common rates at 1.5×
A quick reference, computed with the same engine as the calculator above:
| Base rate | Time-and-a-half rate | 5 OT hours pay |
|---|---|---|
| $15.00 | $22.50 | $112.50 |
| $17.50 | $26.25 | $131.25 |
| $20.00 | $30.00 | $150.00 |
| $22.00 | $33.00 | $165.00 |
| $25.00 | $37.50 | $187.50 |
| $30.00 | $45.00 | $225.00 |
| $35.00 | $52.50 | $262.50 |
| $40.00 | $60.00 | $300.00 |
Not sure how many overtime hours you have?
That's the harder half of the problem — overtime hours depend on your weekly (and in some states, daily) totals, not on any single shift. Switch this page to the full timesheet grid, or use the overtime calculator to enter your actual clock-in/out times; it derives the OT hours for you and prices them at 1.5× automatically.
Frequently asked questions
- What is time and a half of $20 an hour?
- $30 an hour. Multiply any rate by 1.5: $20 × 1.5 = $30, so 5 overtime hours at $20 base pay $150 instead of $100.
- How do I calculate time and a half manually?
- Two steps: multiply your hourly rate by 1.5 to get the overtime rate, then multiply that by your overtime hours. Example: $18/hour → $27 overtime rate; 6 OT hours → $162.
- Is time and a half mandatory?
- For non-exempt employees in the US, yes — federal law requires at least 1.5× pay for hours over 40 in a workweek. It is not required for hours under 40, weekends, or holidays unless a state law or your employment agreement says so.
- When do I get double time instead of 1.5×?
- Federal law never requires double time. California does: after 12 hours in one day, and after 8 hours on the 7th consecutive day of a workweek. The California calculator handles both tiers automatically.
