What This Calculator Does
The Overtime Pay Hours Calculator splits your weekly hours into regular and overtime, then computes your total pay. It follows the standard US FLSA (Fair Labor Standards Act) rule: hours worked beyond 40 in a workweek are paid at one-and-a-half times (1.5×) the regular hourly rate. If you are in another jurisdiction or covered by a different agreement, adjust accordingly — daily overtime rules (e.g. California) are not modeled here.
How to Use It
Enter the total hours you worked in the week and your hourly pay rate. The calculator returns your regular hours (capped at 40), regular pay, overtime hours, overtime pay at time-and-a-half, and the combined total. It works equally well for time-card review, paycheck checking, or estimating a busy week before it happens.
The Formula Explained
Regular hours are \(\min(\text{total hours}, 40)\) and are paid at your normal rate. Overtime hours are \(\max(0, \text{total hours} - 40)\) and are paid at \(\text{rate} \times 1.5\). Total pay is simply regular pay plus overtime pay. If you work 40 hours or fewer, overtime is zero and you are paid straight time.
$$\begin{gathered} \text{Total Pay} = R_{reg}\cdot r + R_{ot}\cdot r \cdot 1.5 \\[1.5em] \text{where}\quad \left\{ \begin{aligned} r &= \text{Hourly Rate} \\ R_{reg} &= \min\!\left(\text{Total Hours},\; 40\right) \\ R_{ot} &= \max\!\left(0,\; \text{Total Hours} - 40\right) \end{aligned} \right. \end{gathered}$$
Worked Example
Suppose you worked 45 hours at $20/hour. Regular hours = 40, regular pay = \(40 \times \$20 = \$800\). Overtime hours = \(45 - 40 = 5\), overtime pay = \(5 \times \$20 \times 1.5 = \$150\). Total weekly pay =
$$\$800 + \$150 = \mathbf{\$950}$$
FAQ
Is overtime always 1.5×? Under federal US law, non-exempt employees earn at least 1.5× for hours over 40 per week. Some employers or states pay double time in certain cases — this tool uses the standard 1.5×.
Does the 40-hour threshold count holidays or PTO? Generally only actual hours worked count toward the 40-hour overtime threshold; paid leave usually does not. Enter your worked hours for an accurate result.
Can I use this for daily overtime? No — this calculator uses the weekly 40-hour rule. States with daily overtime (over 8 hours/day) need a different calculation.
