Work Hours Calculator

To calculate work hours with breaks, subtract your total break time from the time between your start and end. For example: if you start at 9:00 AM and finish at 5:30 PM, that's 8 hours and 30 minutes. Subtract a 30-minute lunch break and you get 8 hours of net work time. This calculator does the math automatically, just enter your times and break duration.

Decimal hours express time as a decimal number instead of hours and minutes. One hour equals 1.0, and minutes are converted as a fraction of 60. So 7 hours 30 minutes becomes 7.5 decimal hours (30 ÷ 60 = 0.5). Decimal hours are used in payroll systems, invoicing software, and timesheets because they make calculations easier. Instead of adding 2:30 + 3:45, you just add 2.5 + 3.75 = 6.25.

Overnight shifts cross midnight, so the end time is technically on the next day. For example: if you start at 10:00 PM (22:00) and end at 6:30 AM, you've worked 8 hours and 30 minutes. Our calculator automatically detects overnight shifts when the end time is earlier than the start time. Another example: a shift from 11:00 PM to 7:00 AM is 8 hours total. Subtract a 30-minute break and you get 7.5 hours (7 hours 30 minutes) of net working time.

Divide the minutes by 60 and add to the hours. For 4 hours 45 minutes: 45 ÷ 60 = 0.75, so the result is 4.75 decimal hours. Common conversions: 15 min = 0.25, 30 min = 0.5, 45 min = 0.75. Our calculator shows both formats automatically so you can use whichever your timesheet or invoice needs.

No, unpaid breaks should be subtracted from your total time at work. If you're on-site from 9 AM to 6 PM but take an hour for lunch, your work hours are 8 hours, not 9. Paid breaks (like short 10-minute rest periods) typically count as work time and shouldn't be subtracted. Check your employment contract if you're unsure which breaks are paid.

Add all your unpaid break time together and enter the total. If you take a 15-minute morning break, 45-minute lunch, and 15-minute afternoon break, that's 75 minutes total. Enter 75 in the break field. The calculator will subtract this from your shift duration to give you net work hours.

Use the Weekly Total tab in our calculator. Enter your start time, end time, and break for each day. Click 'Copy Mon to All' if you work the same hours every day to save time. The calculator adds everything up and shows your weekly total in both hours:minutes and decimal format. Perfect for filling out timesheets or tracking hours for invoicing.

First, calculate your total weekly hours using this calculator. Then compare against your standard hours (typically 40 hours in the US, 37.5-40 in the UK). Anything over is overtime. For example, if your weekly total is 47.5 hours and standard is 40, you have 7.5 overtime hours. Overtime rules vary by country and employment type, so check local regulations.

Very accurate for basic calculations - the math is straightforward. Where errors happen is in the inputs: forgetting to account for unpaid breaks, entering times incorrectly, or not enabling overnight mode for night shifts. Always double-check your entries. Our calculator shows the formula used so you can verify the result yourself.

For freelancers and small businesses, track time daily and convert to decimal hours for cleaner invoices. Tools like Invoice Mama let you create invoices directly from your hours worked - just enter your time and rate, and the total is calculated automatically. For employees, use your company's timesheet system and verify totals weekly before submitting.

In the Weekly Total view, each day has its own break field. Enter the actual break duration for each specific day. Monday might be 30 minutes, but Friday could be 60 if you have a longer lunch. The calculator tracks each day separately and gives you accurate daily and weekly totals.

Payroll and invoicing systems prefer decimal hours because they multiply easily. Calculating pay for 7.75 hours at $25/hour is simple: 7.75 × 25 = $193.75. Try that with 7 hours 45 minutes and you need extra conversion steps. Decimal hours also make weekly totals straightforward to add up without carrying over minutes.

Absolutely. Enter your shift start and end times, toggle overnight mode if needed, and add your break. Works for day shifts, night shifts, rotating schedules, and split shifts. For split shifts, calculate each part separately and add the results. The weekly view is great for tracking irregular schedules across the week.

Many employers round time to the nearest 15 minutes or 6 minutes (0.1 hours). If your shift is 8 hours 7 minutes, it might be recorded as 8 hours or 8.25 hours depending on policy. Our calculator shows exact time - check your employer's rounding rules before submitting timesheets. Over a week, rounding can add up to significant differences.
