What the calculator does with your hours
The federal rule (FLSA) has one trigger: a workweek total above 40 hours. There is no federal daily overtime and no federal double time. So the calculator sums your worked minutes across the week — breaks already deducted — and converts only the minutes past 40 hours to 1.5×.
Two consequences surprise people, and you can verify both right here:
Five 9-hour days = 5 hours of overtime. 45 total hours means hours 41–45 pay 1.5×, regardless of how they were spread across the days.
Four 10-hour days = zero overtime. Long days don't matter federally — only the weekly total does. The same schedule in California would pay 8 hours of daily overtime.
Working in a daily-overtime state? California pays 1.5× after 8 hours in a day and 2× after 12 — the California overtime calculator applies those rules in the right order, including the 7th-day rule.
Calculating overtime in Excel or Google Sheets
The usual spreadsheet approach is a chain like =MAX(0, SUM(D2:D8)-40)*C1*1.5 on top of per-day =(out-in)*24-break/60 cells. It works until it doesn't: time cells silently formatted as text, an overnight shift going negative, breaks entered in hours instead of minutes, or the week boundary drifting when you copy the sheet forward. Each failure produces a number that looks plausible.
This calculator is the same arithmetic with the failure modes removed: overnight shifts wrap automatically, breaks are always minutes, the workweek boundary is an explicit setting, and the rule logic is locked by an automated test suite instead of living in a cell you can overtype.
Heads up: this calculator provides general information for standard non-exempt schedules, not legal or payroll advice. Exemptions and state rules vary — when pay is in dispute, verify with your state labor agency or a qualified professional.
Frequently asked questions
- How is overtime calculated?
- Under the federal FLSA, add up the hours you worked in one workweek; every hour past 40 is paid at 1.5 times your regular rate. This calculator does the split for you: enter your shifts and it prices hours 1–40 at 1× and everything after at 1.5×.
- Is overtime after 8 hours a day or 40 hours a week?
- Federally it is weekly only — a 10-hour day creates no overtime if your week stays at or under 40 hours. A handful of states add daily overtime; California is the biggest, paying 1.5× after 8 hours in a single day. Use the California calculator if you work there.
- Do salaried employees get overtime?
- Some do. Salaried does not automatically mean exempt — exemption depends on the kind of work you do and a minimum salary threshold. Misclassification is common enough that it's worth checking your status rather than assuming. This is general information, not legal advice.
