🧮 Common Time Calculations
Converting Time to Decimals
Minutes to Decimal Hours
15 minutes = 0.25 hours
30 minutes = 0.50 hours
45 minutes = 0.75 hours
Formula: Minutes ÷ 60 = Decimal
Common Conversions
7:30 = 7.50 hours
8:15 = 8.25 hours
8:45 = 8.75 hours
9:20 = 9.33 hours
Weekly Overtime Example
Mon-Fri: 9 hours/day = 45 hours
Regular: 40 hours × $20 = $800
Overtime: 5 hours × $30 = $150
Total: $950
Daily Overtime Example (CA)
Monday: 10 hours worked
Regular: 8 hours × $20 = $160
Overtime: 2 hours × $30 = $60
Daily Total: $220
⚠️ Rounding Rules
The "7-minute rule" allows rounding to the nearest quarter hour:
- • 8:00-8:07 → rounds to 8:00
- • 8:08-8:22 → rounds to 8:15
- • 8:23-8:37 → rounds to 8:30
- • 8:38-8:52 → rounds to 8:45
- • 8:53-9:07 → rounds to 9:00
Note: Rounding must be neutral and not favor the employer
🔧 Troubleshooting Common Issues
Time Entry Errors
Overnight Shifts
If you work past midnight, the calculator automatically handles this. Enter clock-in as 11:00 PM and clock-out as 7:00 AM for an 8-hour shift.
Missing Punches
Always verify time entries match your records. Missing clock-ins or clock-outs can significantly affect calculations.
Break Deductions
Ensure break times are entered correctly. Unpaid breaks should be deducted; paid breaks should not be entered.
Payroll Discrepancies
If Your Pay Is Too Low:
- • Check all hours were recorded
- • Verify overtime calculations
- • Confirm correct pay rates
- • Review deductions
Steps to Resolve:
- 1. Document the discrepancy
- 2. Talk to supervisor/HR
- 3. File written complaint
- 4. Contact labor board if needed

Frequently Asked Questions
How does overtime calculation work?
Overtime is typically calculated when you work more than 40 hours in a week. Hours over this threshold are paid at an overtime rate (usually 1.5x your regular rate). Some states have daily overtime rules where hours over 8 per day are considered overtime.
What time formats are supported?
The calculator supports both 12-hour (9:00 AM, 5:30 PM) and 24-hour (09:00, 17:30) time formats. You can mix formats within the same calculation. The calculator automatically handles overnight shifts when clock-out time is earlier than clock-in time.
How are breaks calculated?
Break time is deducted from your total hours worked. For example, if you work 9 AM to 5 PM (8 hours) with a 30-minute lunch break, your paid hours would be 7.5 hours. Enter break time in minutes for each time entry.
What's the difference between weekly, biweekly, and monthly pay periods?
Weekly: Overtime calculated on hours over 40 per week. Biweekly: Overtime on hours over 80 per two weeks. Monthly: Overtime on hours over approximately 173 per month. Your employer's policy determines which method applies to you.
Can I calculate different overtime rates?
Yes! The default is 1.5x (time-and-a-half), but you can adjust the overtime multiplier. Some situations use 2x (double time) for holidays or excessive hours. Enter your specific rate in the Overtime Multiplier field.
How do I track multiple jobs or pay rates?
For multiple pay rates, calculate each job separately or use the average rate. For accurate tracking, process time entries for each pay rate independently, then sum the totals. Consider using separate calculations for each employer.
