The Complete Guide to Work Hours, Overtime Rules & Timesheets
Accurate timesheet recording is essential for hourly employees, independent contractors, freelancers, and payroll administrators. Even minor discrepancies in recording meal breaks or misapplying overtime multipliers can accumulate into hundreds of dollars in wage loss or labor compliance penalties over the course of an employment year.
How to Calculate Decimal Hours for Payroll
Standard time clocks record time in hours and minutes (e.g., 8 hours and 23 minutes). However, accounting ledgers and automated payroll software require time expressed as decimal hours to multiply by hourly compensation rates.
Decimal Hours Formula:
Example: If you clocked 8 hours and 45 minutes on Tuesday, divide 45 by 60: \(45 \div 60 = 0.75\). Your payroll recorded time is 8.75 hours.
Decimal Hours = Total Hours + (Minutes / 60)Example: If you clocked 8 hours and 45 minutes on Tuesday, divide 45 by 60: \(45 \div 60 = 0.75\). Your payroll recorded time is 8.75 hours.

| 5 min | 0.08 hr | 35 min | 0.58 hr |
| 10 min | 0.17 hr | 40 min | 0.67 hr |
| 15 min | 0.25 hr | 45 min | 0.75 hr |
| 20 min | 0.33 hr | 50 min | 0.83 hr |
| 25 min | 0.42 hr | 55 min | 0.92 hr |
| 30 min | 0.50 hr | 60 min | 1.00 hr |
Understanding Overtime Regulations (FLSA vs. Daily Overtime States)
- The 40-Hour Weekly Standard: Under the Fair Labor Standards Act (FLSA), non-exempt workers in the United States must receive overtime compensation at no less than 1.5 times their regular hourly rate for all hours worked exceeding 40 during a defined 7-consecutive-day workweek.
- Daily Overtime Standards (California, Nevada, Alaska, Colorado): In specific jurisdictions like California, overtime is calculated on a daily basis: hours worked over 8 in a single workday are compensated at 1.5x regular pay, and hours worked over 12 in a single day are compensated at 2.0x double-time pay.
- Overnight Shifts: When a worker clocks in on Thursday evening at 10:00 PM and clocks out Friday morning at 6:30 AM, calculating elapsed time requires handling the midnight rollover (12:00 AM) to ensure hours are accurately attributed without negative durations.
Frequently Asked Questions
What is the 7-minute rounding rule permitted by the Department of Labor?
Under 29 CFR ยง 785.48(b), employers can use 15-minute rounding increments. Clock-ins between 1 and 7 minutes round backward to the previous quarter hour, while times between 8 and 14 minutes round forward to the next quarter hour. The law stipulates that this practice must be neutral and not systematically underpay employees over time.
Do unpaid meal breaks count toward overtime hours?
No. Unpaid meal breaks (usually 30 to 60 minutes where the employee is completely free from performing any work duties) do not count as hours worked and are excluded from the weekly 40-hour overtime threshold.
Can salaried employees qualify for overtime pay?
Yes, if they are classified as "salaried non-exempt" or if their salary falls below the statutory federal or state exemption threshold and they do not satisfy executive, administrative, or professional duty tests.
