Work Hours Calculator

Step 1: Enter how many hours you work per day in the "Hours per Day" field. Include actual working hours, not breaks. A typical full-time worker enters 8.

Step 2: Enter how many days per week you work. Full-time is typically 5 days, part-time might be 3 or 4.

Step 3: Optionally enter your hourly rate. If provided, the calculator shows weekly and yearly pay estimates. Leave at 0 if you just need the hours.

Step 4: Click Calculate. The result shows weekly hours, with the breakdown including daily, monthly (~4.33 weeks), and yearly (~52 weeks) totals, plus pay if a rate was entered.

The standard full-time work schedule in the United States is 40 hours per week — 8 hours per day, 5 days per week. This has been the norm since the Fair Labor Standards Act of 1938 established the 40-hour workweek and required overtime pay beyond that threshold.

Part-time work generally means fewer than 35 hours per week, though the exact definition varies by employer. Part-time workers may work fewer hours per day (e.g., 6 hours), fewer days per week (e.g., 3 days), or both.

Annual hours for a full-time worker total approximately 2,080 hours (40 hours × 52 weeks). However, most workers take vacation, holidays, and sick days. After subtracting 10 holidays, 10 vacation days, and 5 sick days, actual worked hours are closer to 1,880 per year. This calculator shows gross hours without subtracting time off.

Why monthly hours vary: There are not exactly 4 weeks in every month. The average month is 4.33 weeks (52 weeks ÷ 12 months). January has 4.43 weeks while February has 4.0. This calculator uses the 4.33 average for monthly estimates.

Impact on salary calculations: To convert between hourly rate and annual salary, multiply the hourly rate by 2,080 (the standard full-time annual hours). A $25/hour job equals approximately $52,000 per year before taxes and deductions.

Weekly Hours = Hours per Day × Days per Week

Monthly Hours = Weekly Hours × 4.33 (average weeks per month)

Yearly Hours = Weekly Hours × 52

Weekly Pay = Weekly Hours × Hourly Rate

Yearly Pay = Yearly Hours × Hourly Rate

Example: 7.5 hours/day, 5 days/week, $28/hour.
- Weekly: 7.5 × 5 = 37.5 hours ($1,050/week)
- Monthly: 37.5 × 4.33 = ~162 hours
- Yearly: 37.5 × 52 = ~1,950 hours ($54,600/year)

Note: These are gross calculations before taxes, deductions, holidays, vacation, and sick days. Actual take-home pay and worked hours will be lower.

Example 1: Standard Full-Time
Enter 8 hours/day, 5 days/week, $22/hr. Weekly: 40 hours ($880). Monthly: ~173 hours. Yearly: ~2,080 hours ($45,760 gross annual salary).

Example 2: Part-Time Schedule
Enter 6 hours/day, 3 days/week, $18/hr. Weekly: 18 hours ($324). Yearly: ~936 hours ($16,848). This is typical part-time retail or food service work.

Example 3: Compressed 4-Day Week
Enter 10 hours/day, 4 days/week, $35/hr. Weekly: 40 hours ($1,400) — same as standard full-time but with a 3-day weekend. Yearly: ~2,080 hours ($72,800).

Use this to convert between hourly and salary. Multiply hourly rate by 2,080 for the annual salary equivalent. Divide an annual salary by 2,080 to find the equivalent hourly rate.

Monthly estimates are approximate. The 4.33 multiplier is an average. Some months have 4 weeks (28 days), others have 4.43 weeks (31 days). Use weekly or yearly figures for more precise planning.

This does not account for time off. The yearly total assumes working every week. Subtract 2-4 weeks for holidays and vacation to get actual worked hours. A 2-week vacation reduces 2,080 hours to about 2,000.

Overtime changes the math. If you work more than 40 hours per week, hours above 40 should be calculated at 1.5× your rate. This calculator shows base pay without overtime adjustments.

Freelancers: account for non-billable time. If you bill 20 hours/week but spend 10 hours on admin, marketing, and invoicing, your effective hourly rate is lower than your billing rate.
