Whether you're an employee tracking work hours, a freelancer logging billable time, or a manager processing payroll, getting exact hours right matters — mistakes mean wrong paychecks. The CalcHub Hours Calculator converts clock times to total hours worked, with break deductions.

Quick Hours Calculator

Clock In	Clock Out	Break	Hours Worked	Decimal
9:00 AM	5:00 PM	1:00	7:00	7.0
9:00 AM	5:30 PM	0:30	8:00	8.0
8:30 AM	6:00 PM	1:00	8:30	8.5
8:00 AM	4:30 PM	0:45	7:45	7.75
7:00 AM	3:30 PM	0:30	8:00	8.0
10:00 AM	7:00 PM	1:00	8:00	8.0
9:30 AM	6:15 PM	0:45	8:00	8.0

Weekly Timesheet Example

Day	In	Out	Break	Net Hours
Monday	9:00 AM	5:30 PM	0:30	8:00
Tuesday	8:45 AM	5:15 PM	0:30	8:00
Wednesday	9:00 AM	6:00 PM	1:00	8:00
Thursday	9:15 AM	5:45 PM	0:30	8:00
Friday	9:00 AM	4:00 PM	0:30	6:30
Total	38:30

Regular hours: 38:30. If the standard is 40 hours, no overtime applies.

Overnight Shifts

For shifts that cross midnight:

Clock In	Clock Out	Duration
10:00 PM	6:00 AM	8:00
11:00 PM	7:30 AM	8:30
8:00 PM	4:00 AM	8:00
6:00 PM	2:30 AM	8:30

The calculator automatically handles overnight shifts — if the clock-out time is earlier than clock-in, it knows you crossed midnight.

Minutes to Decimal Conversion

Payroll systems often require decimal hours, not minutes:

Minutes	Decimal	Minutes	Decimal
5 min	0.08	35 min	0.58
10 min	0.17	40 min	0.67
15 min	0.25	45 min	0.75
20 min	0.33	50 min	0.83
25 min	0.42	55 min	0.92
30 min	0.50	60 min	1.00

Example: 7 hours 45 minutes = 7.75 decimal hours. At ₹500/hour, that's ₹3,875.

Overtime Calculation

Standard Rules (India — Factories Act)

Regular hours: 48 hours/week or 9 hours/day
Overtime rate: 2× regular rate
Maximum overtime: 50 hours per quarter

Example

Weekly hours: 52:00. Regular: 48:00. Overtime: 4:00.

Component	Hours	Rate (₹/hr)	Amount
Regular	48:00	₹200	₹9,600
Overtime	4:00	₹400 (2×)	₹1,600
Total	52:00	₹11,200

Freelancer Billing

For freelancers tracking billable hours:

Task	Start	End	Billable Hours	Rate	Amount
Client call	10:00	11:15	1.25	₹2,000/hr	₹2,500
Design work	11:30	2:00 PM	2.50	₹2,000/hr	₹5,000
Revisions	3:00 PM	4:45 PM	1.75	₹2,000/hr	₹3,500
Total	5.50	₹11,000

How to Use the Calculator

Open the CalcHub Hours Calculator
Enter clock-in time (e.g., 9:00 AM)
Enter clock-out time (e.g., 5:30 PM)
Enter break duration (optional)
See: total hours in both HH:MM and decimal format

For weekly totals, enter each day's hours and the calculator sums them.

Should I round my hours?

Many companies use 15-minute rounding: 9:07 rounds to 9:00, 9:08 rounds to 9:15. Check your company's policy. For freelancing, bill to the nearest 15 minutes — it's the industry standard and keeps invoicing clean.

How do I calculate my hourly rate from salary?

Hourly rate = Annual salary / (52 weeks × hours per week)

For ₹6,00,000/year at 40 hours/week: ₹6,00,000 / 2,080 = ₹288.46/hour.

How many work hours are in a year?

Standard: 52 weeks × 40 hours = 2,080 hours. After typical holidays and leave (30 days): approximately 1,840 working hours.
