Daily Overtime Pay Calculator (Federal + California Rules)
Enter Monday-through-Sunday hours and a base rate; the calculator applies federal weekly OT (over 40), California daily OT (over 8), and California double-time (over 12 or 8h on the 7th consecutive day) to break out gross pay.
Total: 48 h
Per-day breakdown

Note: any >40 weekly regular hours are reclassed to OT in the totals to avoid double-counting daily-and-weekly bases.
Federal rule per FLSA 29 U.S.C. §207(a)(1). California rule per Cal. Labor Code §510 and the DIR Overtime FAQ (1.5× >8/day, 2× >12/day, 7th-day rule). Result is gross pay before taxes. Educational; everything runs in your browser.
About this tool
The week-totals version of an overtime calculator is fine when overtime is purely weekly, but several US states layer daily overtime on top — and once daily rules apply, the answer depends on how the hours are spread across the week, not just the total. California is the headline example. Under California Labor Code §510, non-exempt employees earn time-and-a-half for hours worked over 8 in a single workday and over 40 in the workweek, double-time for hours over 12 in a single workday, and on the seventh consecutive workday of a single workweek they earn time-and-a-half for the first 8 hours and double-time for everything beyond. This calculator takes per-day hours for Monday through Sunday plus the base rate, and applies one of three rulesets — federal only (the FLSA's weekly 40-hour rule), California (the daily-plus-weekly-plus-seventh-day rule above), or a Colorado-style hybrid (daily over 12, weekly over 40, whichever yields more) — without double-counting an hour as both daily and weekly overtime. The output is regular hours, OT hours, double-time hours, and the gross paycheck, with a per-day breakdown so you can see why a 50-hour week distributed 10-10-10-10-10 (federal: 10 OT, no DT) costs more under California than the same hours distributed 8-8-8-8-8-8-2 (CA: 2 daily-OT from the 7th day plus 2 weekly-OT extras handled by the seventh-day rule). It also handles a worker who already accrued seven consecutive workdays earlier in the same workweek — toggle the 'seventh day' flag for Sunday. This is gross pay; nothing is uploaded, and the constants embedded in each ruleset are the statutory rates as published by the US Department of Labor (FLSA) and the California Department of Industrial Relations, cited in the methodology note.

Frequently asked questions
- What is the rule under federal law (FLSA)?
- Non-exempt employees earn at least 1.5× their regular rate for hours worked over 40 in a workweek. There is no federal daily overtime rule — 10 hours in a single day is fine if the week stays under 40 total. (29 U.S.C. §207(a)(1); 29 CFR Part 778.)
- What is the rule in California?
- Time-and-a-half for hours over 8 in a workday and over 40 in a workweek; double-time for hours over 12 in a workday. On the seventh consecutive workday of a workweek: time-and-a-half for the first 8 hours and double-time after 8. Hours are not double-counted across daily and weekly bases — the higher rate prevails. (Cal. Labor Code §510; California DIR FAQ on Overtime.)
- How does the seventh-day rule work?
- If the employee works all seven days in a single workweek, the seventh day's first 8 hours are time-and-a-half and any hours past 8 on that day are double-time, even if no other daily threshold was met. Toggle the "seventh consecutive day" flag on the Sunday row to enable this. The workweek is a fixed 7-day window your employer designates; here it is treated as Mon-Sun.
- How is the no-double-count rule enforced?
- For each day, hours are first classified as DT (>12 or seventh-day >8), then OT (>8), then regular. Regular hours are then summed; if the weekly regular total exceeds 40, the excess is reclassified as OT. This prevents an hour from being counted as both daily OT and weekly OT.
- Is overtime based on the base wage only?
- Federally and in California, overtime is based on the regular rate of pay, which includes non-discretionary bonuses, commissions, and shift differentials averaged across the workweek. This tool uses the base rate you enter; if the worker has a bonus that week, divide the bonus by the total hours and add it to the base rate before entering.
- Is the result before or after taxes?
- Gross — before federal income tax, state income tax, FICA, Medicare, and any voluntary withholding.
