Quick answer: Under federal law (FLSA), non-exempt employees get 1.5× their regular rate for hours over 40 in a workweek — no daily overtime and no double time. California adds a daily layer: 1.5× after 8 hours in a day, 2× after 12, and on the seventh consecutive day the first 8 hours are 1.5× and anything beyond is 2×, plus 1.5× on straight-time hours over 40 for the week. Enter each day's hours and the hourly rate, and the tool splits the week into regular, time-and-a-half, and double-time hours, shows the pay, compares federal against California, and produces a PDF statement built locally with jsPDF. It is for non-exempt employees and is a calculation aid, not legal advice.

Overtime Pay Calculator – Complete Guide
"Overtime after 40 hours" is only half the story. In California a single 10-hour day already triggers overtime, and a 13-hour day triggers double time, whatever the weekly total. Calculating by weekly hours alone misses all of that - and underpays people.
Federal vs California Overtime
| Trigger | Federal (FLSA) | California |
|---|---|---|
| Over 40 hours in the workweek | 1.5× | 1.5× (straight-time hours) |
| Over 8 hours in a day | No requirement | 1.5× (up to 12 hours) |
| Over 12 hours in a day | No requirement | 2× |
| Seventh consecutive workday | No requirement | First 8 hours 1.5×, beyond 8 hours 2× |
Based on the Fair Labor Standards Act and California Labor Code sections 510-511, as consistently summarised in 2026 guidance. Double time is never triggered by the weekly total alone.
A Worked Example
Take someone paid $20 an hour who works two 12-hour days and nothing else. Federal law sees 24 hours - under 40 - so there is no overtime: 24 × $20 = $480. California sees two long days: each has 8 regular hours and 4 at 1.5×, so 16 × $20 + 8 × $30 = $560. Same hours, $80 more.
How This Calculator Actually Works
In federal mode the tool totals the week, pays up to 40 hours at the regular rate, and pays anything beyond at 1.5×. In California mode it processes each day in workweek order. A day's first 8 hours are regular, hours 9 to 12 are 1.5×, and anything past 12 is 2×. If the first six days all have hours and the seventh does too, that seventh day is treated differently: its first 8 hours are 1.5× and any beyond are 2×. After the daily split, the tool adds up the remaining straight-time hours across the week - the ones not already paid at a premium - and any of those beyond 40 are paid at 1.5×, so no hour is premium-paid twice. It also runs the federal calculation on the same hours so you can see the difference. jsPDF and jsPDF-AutoTable then draw the statement. Nothing ever touches a server.

Troubleshooting Common Issues
Explanation: The premium only applies when all seven days of the workweek have hours. Solution: Check that every day, including day 7, has hours entered, and that days are in workweek order.
Explanation: When no day exceeds 8 hours and the weekly total is the same either way, the rules produce the same pay. Solution: This is expected for ordinary 8-hour days.
Explanation: A day can't have more than 24 hours. Solution: Check the hours entered for that day.
Explanation: The PDF needs both parties identified. Solution: Fill in both names, then download again.
Frequently Asked Technical Questions
Question 1: What actually builds the PDF - is it a known library?
Answer: This tool uses jsPDF, a widely used open-source JavaScript library for generating PDF documents in the browser, with its jsPDF-AutoTable plugin for the tables, both loaded directly in your browser tab.
Question 2: How does the tool avoid paying the same hour a premium twice?
Answer: Daily overtime and double-time hours are removed from the straight-time total before the weekly check, so only straight-time hours beyond 40 become weekly overtime.
Question 3: How is the seventh consecutive day detected?
Answer: The tool treats day 7 as a seventh-day shift only when days 1 through 6 and day 7 all have hours greater than zero.
Question 4: Why are the days labelled "Day 1" to "Day 7"?
Answer: The seventh-day rule depends on position in the workweek, so the boxes follow workweek order; entering a start date relabels them with weekday names.
Question 5: Does this tool need an account, server, or API key?
Answer: No. jsPDF and the live preview both run as ordinary JavaScript already loaded by this page — you never need an account or any API key to use it.

Frequently Asked Questions
Yes, completely free with no watermark, no signup, and no limit on calculations or statements.
No. Everything is calculated and turned into a PDF inside your browser using JavaScript. Nothing is transmitted over the network.
Under the Fair Labor Standards Act, non-exempt employees must be paid at least 1.5 times their regular rate for every hour worked over 40 in a workweek.
No. Federal law has no daily overtime requirement and no double-time requirement. Someone could work 12 hours one day and 4 the next with no federal overtime owed, because the weekly total is under 40.
California requires time and a half for hours over 8 in a day, up to 12, and double time for hours over 12 in a day, in addition to time and a half for straight-time hours over 40 in a workweek.
On the seventh consecutive day of work in a workweek, the first 8 hours are paid at 1.5 times the regular rate and hours beyond 8 at double the regular rate.
No. Double time depends on hours in a single day or on the seventh consecutive workday. The weekly total alone never triggers double time.
It can include more than base hourly pay, such as certain bonuses and shift differentials. This tool uses the hourly rate you enter, so enter the correct regular rate for your situation.
This tool is for non-exempt employees. Being paid a salary does not by itself make someone exempt; exemption depends on meeting the legal tests, so check your classification.
Federal law sets a floor and some states add their own overtime rules on top. This tool covers the federal rule and California's rules, so check your own state's requirements if you work elsewhere.
Final Thoughts
Overtime errors usually come from using the wrong trigger - weekly hours when daily rules apply, or forgetting the seventh-day premium. This tool applies each rule in the right order, shows the working, and compares the two rule sets — all without your hours or pay leaving your device.
