Understanding Work Hours
How Work Hours Are Calculated
Work hours are typically calculated from clock-in to clock-out time, minus any unpaid breaks. Different employers have different policies regarding paid vs. unpaid breaks, overtime, and rounding rules.
Basic Formula
Standard Full-Time Hours
| Period | Hours | Calculation |
|---|---|---|
| Day | 8 | Standard workday |
| Week | 40 | 8 × 5 days |
| Month | 173.33 | 40 × 52 / 12 |
| Year | 2,080 | 40 × 52 weeks |
Overtime Rules (US)
Federal (FLSA)
Non-exempt employees must receive 1.5× pay for hours over 40 per week. No federal requirement for daily overtime.
California
1.5× for hours over 8/day or 40/week. 2× for hours over 12/day or on 7th consecutive day.
Time Rounding
Many employers round time to the nearest 5, 6, or 15 minutes. Federal law allows rounding if it evenly averages out over time.
Common Rounding Methods
- :01-:07 rounds down
- :08-:22 rounds to :15
- :23-:37 rounds to :30
- :01-:03 rounds down
- :04-:09 rounds to :06
- :10-:15 rounds to :12
Hourly to Salary Conversion
Hourly Rate = Annual Salary ÷ 2,080
| Hourly | Weekly | Monthly | Annual |

| $20 | $800 | $3,467 | $41,600 |
| $25 | $1,000 | $4,333 | $52,000 |
| $30 | $1,200 | $5,200 | $62,400 |
| $40 | $1,600 | $6,933 | $83,200 |
| $50 | $2,000 | $8,667 | $104,000 |
Important Note
These calculations assume a standard schedule without PTO, holidays, or sick days. Actual annual hours may be lower. Additionally, the salary-to-hourly conversion doesn't account for benefits, bonuses, or other compensation.
Frequently Asked Questions
How many work hours are in a year?
A full-time employee working 40 hours/week for 52 weeks = 2,080 hours/year. After typical PTO (10 days vacation, 10 holidays, 5 sick days), actual work is closer to 1,880 hours. Use 2,080 for salary conversions.
How do I convert hourly wage to annual salary?
Multiply hourly rate by 2,080 (40 hrs x 52 weeks). $15/hour = $31,200/year. $25/hour = $52,000/year. For monthly, divide annual by 12 or multiply hourly by 173.33 (average hours/month).
What counts as overtime and how is it calculated?
Federal law requires 1.5x pay for hours over 40/week for non-exempt employees. Some states (like California) also require daily overtime after 8 hours. Double time may apply after 12 hours/day or on the 7th consecutive day in some states.
Should lunch breaks be included in work hours?
Typically no - meal breaks of 30+ minutes are usually unpaid if you're completely relieved of duties. Short breaks (5-20 minutes) are generally paid. Rest breaks (10-15 min per 4 hours) are required in some states and are paid time.
