How It Works
Convert clock-in/out times to payroll-ready decimal hours
This timesheet calculator converts your daily clock-in and clock-out times into total work hours with support for weekly and biweekly pay periods, automatic lunch deduction, payroll-style time rounding, and overtime calculation.
Core Formula
Net Hours = (Clock Out − Clock In) − Break Minutes ÷ 60
Weekly & Biweekly
7 or 14-day periods with per-week subtotals
Auto Lunch
Replaces manual break for shifts over a set threshold
Time Rounding
5, 6, or 15-minute payroll rounding modes
Overnight Shifts
Auto-detects shifts crossing midnight
Worked Example

Clock In:9:00 AM
Clock Out:5:30 PM
Break:30 min
Result
Duration:8h 0m
Decimal:8.00 hrs
8.5h − 0.5h break
Time Rounding for Payroll
How employers round timesheet entries and FLSA compliance rules
Many employers round timesheet entries to simplify payroll processing. The 7-minute rule is the most common: with 15-minute rounding, 1-7 minutes round down and 8-14 minutes round up.
15
Quarter-Hour Rounding
Most common in the US. Each 15 minutes = 0.25 hours. Used by the majority of hourly employers.
7:07 AM → 7:007:08 AM → 7:15
6
Tenth-Hour Rounding
Popular with law firms and consulting. Each 6 minutes = 0.1 hours. Provides finer billing granularity.
7h 18m → 7.3h7h 24m → 7.4h
5
Five-Minute Rounding
Finer granularity for employers wanting less rounding error. 12 increments per hour.
7h 22m → 7h 20m7h 23m → 7h 25m
FLSA ComplianceUnder the Fair Labor Standards Act, rounding must average out fairly over time. An employer cannot use a rounding practice that consistently favors the employer and shortchanges employees.
Minutes to Decimal Conversion
Quick reference chart for converting timesheet minutes to decimal hours
Payroll systems require decimal hours rather than hours and minutes. Divide minutes by 60 to convert.
Decimal Hours = Minutes ÷ 60

Overtime Rules
Federal FLSA standard vs state-specific daily overtime laws
Overtime laws vary by jurisdiction. This calculator supports both major methods with configurable thresholds and multipliers.
Weekly (FLSA)
Federal standard. Hours over 40 per week paid at 1.5× rate.
42h week: 40h regular + 2h OT
Used by most US states
Daily (e.g., California)
Some states require OT after 8 hours per day, regardless of weekly total. Rules vary by state.
10h day: 8h regular + 2h OT
Check your state labor laws
Pay Calculation
1.5×
Time and a half — Standard OT rate. $20/hr → $30/hr OT.
2.0×
Double time — CA after 12h/day or 7th consecutive day. $20/hr → $40/hr.
Common Mistakes
Rounding time to always favor employer
Rounding must be neutral over time (FLSA)
Skipping lunch breaks on long shifts
Most states require breaks after 5-6 hours
Using HH:MM math for payroll (1:30 ≠ 1.30)
Convert to decimal first: 1h 30m = 1.50h
Assuming OT is always weekly
Some states have daily OT — check your state laws
Frequently Asked Questions
Common questions and detailed answers
Subtract your clock-in time from your clock-out time, then deduct any break time. For example, if you clock in at 9:00 AM and clock out at 5:30 PM with a 30-minute lunch, your net hours are 8 hours (8.5 hours − 0.5 hours break). Convert to decimal by dividing remaining minutes by 60.
A weekly timesheet covers 7 days (one work week), while a biweekly timesheet covers 14 days (two work weeks). Biweekly is the most common pay period in the US — about 43% of employers use it. Overtime is calculated per week even on biweekly timesheets.
Employers may round timesheet entries to the nearest 5, 6, or 15 minutes. With 15-minute rounding (most common), 7 minutes rounds down and 8 minutes rounds up. Under FLSA rules, rounding must be neutral over time — it cannot consistently short-change employees. For example, 7:07 AM rounds to 7:00 AM, but 7:08 AM rounds to 7:15 AM.
Divide the minutes by 60. Common conversions: 15 min = 0.25, 30 min = 0.50, 45 min = 0.75. For example, 7 hours 45 minutes = 7.75 decimal hours. Most payroll systems require decimal format for accurate pay calculation.
When enabled, auto lunch automatically applies a lunch break (e.g., 30 minutes) for any shift exceeding a configurable threshold (e.g., 6 hours). It replaces the manual break for qualifying shifts — the break column shows the auto-deducted amount and becomes non-editable. Shorter shifts that don't meet the threshold still allow manual break entry. Many US states require meal breaks for shifts over 5–6 hours, making this feature useful for compliance.
Under federal FLSA rules, overtime kicks in after 40 hours per week at 1.5× your regular rate. Some states like California use daily overtime — hours over 8 per day are overtime regardless of weekly total. This calculator supports both methods with adjustable thresholds.
Yes. If the clock-out time is earlier than the clock-in time, the calculator automatically detects an overnight shift and adds 24 hours. For example, a shift from 10:00 PM to 6:00 AM is correctly calculated as 8 hours. Overnight shifts are marked with a moon icon in the breakdown.
The time picker uses a 12-hour AM/PM format. Select the hour, minute, then tap PM for afternoon and evening shifts. For example, 1:00 PM is equivalent to 13:00 military time. The calculator stores times internally in 24-hour format and handles all conversions automatically.
