Work Hours & FLSA Overtime Pay Formula

Last reviewed: September 2026

Calculation Formula

Gross Pay = (Regular Hours × Base Rate) + (Overtime Hours × Base Rate × 1.5)

Variables & Definitions

Daily Hours:: (Clock Out - Clock In) in minutes - Unpaid Break minutes
Weekly Total:: Sum of all daily worked hours across the 7-day pay period
Regular Hours:: min(40, Weekly Total Hours)
Overtime Hours:: max(0, Weekly Total Hours - 40)
Overtime Rate:: Base Hourly Rate × 1.5 (FLSA time-and-a-half standard)

Core Assumptions

Standard 40-hour weekly overtime threshold conforming to the US Fair Labor Standards Act (FLSA).
All logged break durations represent unpaid meal periods.
Hourly rate applies uniformly across all standard weekday and weekend shifts.
Shifts that cross midnight (graveyard/night shifts) are calculated continuously across the 24-hour cycle.

Disclaimer: Calculated totals estimate gross pay before mandatory statutory deductions, including Federal Income Tax withholding, state/local income tax, FICA (Social Security & Medicare), and employer health insurance or 401(k) contributions. Certain states (e.g., California, Alaska, Nevada) enforce daily overtime rules after 8 hours in a single day.

Worked Example: 43.5 Weekly Work Hours with Overtime

A manufacturing technician works Monday through Friday at a $25.00/hour base wage. They work 8.0 net hours on Mon, Tue, Wed, Thu, and an extended 11.5 net hour shift on Friday (each with a 30-minute unpaid lunch break):

Total Hours Worked	43.50 decimal hours (43 hours, 30 minutes)
Regular Hours (First 40 hrs)	40.00 hrs × $25.00/hr = $1,000.00
Overtime Hours (> 40 hrs)	3.50 hrs × $37.50/hr (1.5× rate) = $131.25
Total Estimated Gross Pay	$1,131.25

💡 Because the 3.5 excess hours are billed at the 1.5× overtime multiplier ($37.50/hr), the worker earns $131.25 in overtime pay for a total weekly gross wage of $1,131.25.

Why use this tool?

Full 7-Day Timecard with Daily Break Deductions

Whether you work a standard Monday–Friday schedule, a compressed 4x10 shift, or weekend shifts, enter clock-in and clock-out times with instant lunch break deductions.

Both Decimal Hours and Hours:Minutes Formats

Payroll processing systems (like ADP, Gusto, or QuickBooks) require decimal numbers (e.g. 7.50 hrs instead of 7h 30m). UsefulGo shows both formats side-by-side so you never make transcription errors.

Frequently asked questions

How does unpaid lunch break deduction work?

When you clock in at 9:00 AM and clock out at 5:30 PM, the total elapsed span is 8 hours and 30 minutes. If you specify a 30-minute unpaid lunch break, the calculator subtracts 30 minutes to give 8.00 billable hours worked.

How do decimal hours convert from hours and minutes?

To convert minutes to decimal hours, divide the minutes by 60. For example: 15 minutes = 0.25 hours, 30 minutes = 0.50 hours, and 45 minutes = 0.75 hours. An 8-hour and 20-minute shift converts to 8 + (20/60) = 8.33 decimal hours.

What is the 7-minute time rounding rule (15-minute intervals)?

Under US federal FLSA guidelines, employers are allowed to round employee clock punches to the nearest 15-minute quarter-hour interval. Under the 7-minute rule: minutes 1 through 7 round down to the nearest quarter hour, while minutes 8 through 14 round up to the next quarter hour. You can choose "15 min (7-min rule)" in our rounding selector to mirror this system.

Does this calculator support graveyard and night shifts that cross midnight?

Yes. If your shift starts at 10:00 PM (22:00) and ends at 6:30 AM (06:30) the following morning, the calculator detects that the end time is numerically less than the start time and automatically adds 24 hours, computing a clean 8.5-hour shift.

What is the difference between daily overtime and weekly overtime?

Under US federal law (FLSA), overtime is calculated on a weekly basis for hours worked in excess of 40 in a workweek. However, certain states (most notably California) mandate daily overtime: any hours worked over 8 in a single day must be paid at 1.5×, and hours over 12 must be paid at 2.0× double-time.
