What is a Hours Worked Calculator?
A hours worked calculator is a time tracking tool that computes the exact duration between a start time and end time, subtracts break periods, and displays results in multiple formats. It’s essential for:
- Employees tracking daily work hours for accurate pay
- Freelancers billing clients by the hour
- Managers calculating team schedules and labor costs
- Payroll departments processing timesheets efficiently
How to Calculate Hours Worked Between Two Times
Calculating work hours manually can be error-prone, especially with overnight shifts or multiple breaks. Here’s the simple process:
Step 1: Note Your Times
Record your clock-in time (start) and clock-out time (end). Use 24-hour format for clarity:
- 9:00 AM = 09:00
- 5:00 PM = 17:00
- 11:00 PM = 23:00
Step 2: Account for Breaks
Add up all unpaid break time in minutes. Common breaks:
- Lunch break: 30-60 minutes
- Coffee breaks: 10-15 minutes each
- Total breaks should be subtracted from work time
Step 3: Calculate Total Time
The calculator does the math:
- Converts times to minutes
- Subtracts start from end
- Deducts break minutes
- Converts back to hours and minutes
Step 4: Get Decimal Hours
For payroll systems, you need decimal format:
- 7 hours 30 minutes = 7.5 hours
- 8 hours 15 minutes = 8.25 hours
- 9 hours 45 minutes = 9.75 hours
How Do I Calculate My Hours Worked?
Using our calculator is straightforward:
Example 1: Standard Day Shift
- Start: 08:00 (8:00 AM)
- End: 17:00 (5:00 PM)
- Break: 60 minutes (lunch)
- Result: 8h 0m = 8.00 hours
Example 2: Part-Time Shift with Break
- Start: 12:00 (12:00 PM)
- End: 18:30 (6:30 PM)
- Break: 15 minutes
- Result: 6h 15m = 6.25 hours
Example 3: Overnight Shift
- Start: 22:00 (10:00 PM)
- End: 06:00 (6:00 AM next day)
- Break: 30 minutes
- Result: 7h 30m = 7.50 hours
How to Calculate Work Hours for Payroll
Payroll departments need precise time tracking. Here’s how to use this calculator for payroll:
Converting to Decimal Hours
Most payroll systems require decimal hours, not HH:MM format. Our calculator provides both:
| Time Format | Decimal Hours |
|---|---|
| 7:00 | 7.00 |
| 7:15 | 7.25 |
| 7:30 | 7.50 |
| 7:45 | 7.75 |
| 8:00 | 8.00 |
Weekly Hours Calculation
Track daily hours and sum for weekly total:
- Monday: 8.00 hours
- Tuesday: 7.50 hours
- Wednesday: 8.25 hours
- Thursday: 8.00 hours
- Friday: 6.75 hours
- Weekly Total: 38.50 hours
Overtime Calculation
If your workday exceeds standard hours (typically 8 hours):
- Regular time: First 8 hours at base rate
- Overtime: Hours beyond 8 at overtime rate (often 1.5x)
Example: 10-hour shift = 8 regular + 2 overtime
How Do You Calculate Hours and Minutes Worked?
Our calculator shows time in two formats to serve different needs:
HH:MM Format (Hours:Minutes)
Best for:
- Personal time tracking
- Shift schedules
- Quick visual reference
- Time cards
Example: 09:00 to 17:30 with 30-min break = 8h 0m
Decimal Format
Best for:
- Payroll processing
- Billing clients
- Spreadsheet calculations
- Multiplying by hourly rate
Example: Same shift = 8.00 hours × $15/hr = $120
Calculate Hours Worked with Lunch Break
Most employees take unpaid lunch breaks. Here’s how to account for them:
Common Break Scenarios
30-Minute Lunch Break:
- 09:00 – 17:30 shift
- Subtract 30 minutes
- Net work time: 8 hours
1-Hour Lunch Break:
- 08:00 – 17:00 shift
- Subtract 60 minutes
- Net work time: 8 hours
Multiple Breaks:
- 09:00 – 18:00 shift
- Lunch: 45 minutes
- Coffee breaks: 15 minutes total
- Total breaks: 60 minutes
- Net work time: 8 hours
Paid vs Unpaid Breaks
Unpaid breaks (subtract from total):
- Meal breaks (30-60 minutes)
- Extended personal breaks
Paid breaks (don’t subtract):
- Short rest breaks (5-10 minutes)
- Some coffee breaks
- Company-paid meal time
Always verify your company’s break policy.
How to Calculate Overnight Shift Hours
Overnight or graveyard shifts that cross midnight require special handling—our calculator does this automatically.
Midnight-Crossing Detection
The calculator recognizes overnight shifts when the end time is earlier than the start time:
Example Overnight Shifts:
- 22:00 – 06:00 (10 PM to 6 AM)
- Duration: 8 hours
- Crosses midnight: Yes ✓
- 23:30 – 07:30 (11:30 PM to 7:30 AM)
- Duration: 8 hours
- Crosses midnight: Yes ✓
- 20:00 – 04:00 (8 PM to 4 AM)
- Duration: 8 hours
- Crosses midnight: Yes ✓
Night Shift Pay Calculation
Many employers pay a shift differential for overnight work:
- Base rate: $15/hour
- Night differential: +$2/hour
- Overnight rate: $17/hour
Use the calculator to get decimal hours, then multiply by your night rate.
How to Calculate Your Work Hours Per Week
To track weekly hours, calculate each day separately and sum the decimal hours:
Weekly Tracking Example
| Day | Start | End | Break | Hours |
|---|---|---|---|---|
| Mon | 08:00 | 17:00 | 60 min | 8.00 |
| Tue | 08:30 | 17:30 | 60 min | 8.00 |
| Wed | 09:00 | 18:00 | 60 min | 8.00 |
| Thu | 08:00 | 16:30 | 30 min | 8.00 |
| Fri | 08:00 | 13:00 | 0 min | 5.00 |
| Total | 37.00 |
Full-Time vs Part-Time
Full-time: Typically 35-40 hours/week Part-time: Usually under 30 hours/week Overtime: Hours beyond 40/week (US standard)
How Much is My Hourly Pay Worth?
Use the estimated pay feature to see your earnings:
Pay Calculation Formula
Total Pay = Decimal Hours × Hourly Rate
Examples (US rates):
- 8.00 hours × $15.50/hr (CA factory) = $124.00
- 7.50 hours × $7.25/hr (federal min) = $54.38
- 8.00 hours × $50/hr (software dev) = $400.00
US Minimum Wage Context (2025)
Federal minimum: $7.25/hr (since 2009) State minimums vary widely:
- California: ~$16/hr
- New York: ~$15-16/hr
- Washington: ~$16.66/hr
- Texas/Wyoming: $7.25/hr (federal)
Tipped workers: $2.13/hr + tips (must reach state minimum) Skilled professionals: $50+/hr (developers, nurses, etc.)
Including Overtime
Example with overtime (US rates):
- Regular: 8 hours × $15.50 = $124.00
- Overtime: 2 hours × $23.25 (1.5x) = $46.50
- Total: $170.50

Frequently Asked Questions
How do I calculate hours between two times?
Enter your start time and end time in the calculator, add any break minutes, and click Calculate. The tool instantly shows your total hours in both HH:MM format and decimal hours.
Does this work for overnight shifts?
Yes! The calculator automatically detects when your shift crosses midnight (end time earlier than start time) and calculates the correct duration across days.
How do I convert hours and minutes to decimal?
The calculator does this automatically. For manual conversion: divide minutes by 60. Example: 7 hours 30 minutes = 7 + (30÷60) = 7.5 hours.
