For each day from Monday to Sunday, enter the clock-in and clock-out times and the break in minutes. Leave days you did not work blank. Enter an hourly wage in dollars to get the estimated pay too.
Enter times such as "9:00 AM" or "5:30 PM" ("9 AM" is fine too). The 24-hour clock, such as "17:30", also works. Days with both times blank are not counted. A blank break counts as 0 minutes. If the clock-out time is earlier than the clock-in time, the day is treated as an overnight shift that ended the next day.
Result
Enter the clock-in and clock-out times for each day (plus breaks and your hourly wage) in the fields on the left and press "Calculate". The result will appear here.

What you can do on this page
- Enter the clock-in and clock-out times and the break (in minutes) for each day from Monday to Sunday, and you get the hours worked each day and the total for the week right away
- The weekly total is shown both as "37 h 30 min" and as decimal hours, "37.5 h", which you can multiply by an hourly wage as is
- Enter your hourly wage in dollars, and the estimated pay (total hours in decimal hours × hourly wage) is calculated too
- Overnight shifts, such as clocking in at 10:00 PM and out at 6:00 AM the next morning, are handled too
- A plain-language explanation of the formulas and copy-and-paste formulas for Excel, Google Sheets and Python are all on this page
To calculate a single shift, the related page "Work Hours Calculator" is more convenient (this page is the weekly version and adds up a whole week). The estimated pay is a simple multiplication, total hours (decimal hours) × hourly wage. Overtime pay (in the US, usually 1.5 times the regular rate for hours over 40 in a workweek), shift differentials and deductions such as taxes depend on the law where you work and on your employer, so this calculator does not include them.
What is this calculation used for?
Estimating your weekly pay from an hourly wage
If you work 9:00 AM to 5:30 PM on 5 weekdays with a 1-hour unpaid lunch break each day, you work 7 hours 30 minutes × 5 days = 37 hours 30 minutes a week. Multiply 37.5 decimal hours by an hourly wage of $18, and that week's pay comes to about \(37.5 \times 18 = 675\) dollars.
When you can work out "how much did I earn this week?" yourself, you can plan your shifts and income with numbers instead of guesses. (Your actual paycheck changes with overtime, taxes and other deductions, so check the exact amount on your pay stub.)
Checking your schedule and pay stub (knowing your own hours)
If you can add up your weekly hours yourself from your time card or time-tracking app, you can check how your actual hours compare with your schedule, and whether the hours on your pay stub match your own records.
An employer's timekeeping system does the same thing inside: for each day it finds clock-out − clock-in − break and adds the days up. Knowing how it works is the first step to making sure you are paid for all the time you worked.
Keeping an eye on weekly hour limits (overtime and part-time)
Several common rules in the US look at hours per week. Under the federal Fair Labor Standards Act (FLSA), hourly (non-exempt) workers are generally paid 1.5 times their regular rate for hours over 40 in a workweek. For example, working 8:00 AM to 5:30 PM with a 30-minute break is 9 hours a day, or 45 hours over 5 days, which is 5 hours of overtime. At $20 an hour, those 5 hours pay \(20 \times 1.5 \times 5 = 150\) dollars.
Other limits also count weekly hours: large employers generally treat 30 or more hours a week as full-time for health coverage under the Affordable Care Act, and international students on an F-1 visa are generally limited to 20 hours a week of on-campus work while school is in session. The exact rules can differ and can change, so check the current rules with your employer or school. Either way, this weekly total tells you exactly how many hours you worked.
Adding up a week that includes night shifts (nursing, care work, factories, 24-hour stores)
For a night shift from 22:00 (10:00 PM) to 6:00 the next morning, the numbers alone give "6 − 22", which is negative. Add one day, 1440 minutes, and you see it is an 8-hour shift.
Even in a week that mixes night shifts and day shifts, you just find each day's hours with the same rule and add them up, so the total does not get mixed up. You can check for yourself whether the weekly total on your schedule is right.
Logging weekly hours for study or a side job
If you write down "from when to when", you can use the same calculation to add up how many hours a week you spent on something other than your main job, such as studying for an exam or a side gig from home.
Seeing the weekly total lets you look back with numbers, for example "Did I make up on the weekend for the study time I skipped on weekdays?"

②
subtract the
\(T_1\): clock-in time in minutes
③
then subtract the
\(B\): break
④
and you get the
\(W\): hours worked in the day
⑤
If the clock-out time is earlier than the clock-in time (an overnight shift), the clock-out was on the next day, so add the
\(1440\): minutes in 1 day
before subtracting the break (the second formula)
Quick example
For a day with clock-in at 9:00, clock-out at 17:30 and a 60-minute break, the hours worked are
hours worked (450 min = 7 h 30 min)
\(=\)
clock-out (1050 min)
\(-\)
clock-in (540 min)
\(-\)
break (60 min)
\(W = 1050 - 540 - 60 = 450\)
\(450 = 60 \times 7 + 30\)
Key idea
First, each time is turned into minutes after midnight with "60 × hour + minute" (9:00 → 540 minutes, 17:30 → 1050 minutes). Once the times are in minutes, the rest is a plain subtraction. To learn this step in detail for a single shift, see the related page "Work Hours Calculator".
For a night shift, such as clocking in at 22:00 and out at 6:00 the next morning, the subtraction gives a negative number, so add one day, \(1440\) minutes (\(= 24 \times 60\)), before subtracting the break (example: \(360 - 1320 = -960\), and \(-960 + 1440 = 480\) minutes = 8 hours). If the clock-in and clock-out times are the same, this page treats the day as "0 h" (not as a 24-hour shift).

Then divide the weekly total \(S\) by

④
and you get the

(hours as a decimal, ready to multiply by an hourly wage)
Quick example
With 7 h 30 min (450 minutes) worked on each of 5 weekdays (no work on the weekend), the weekly total and decimal hours are
weekly total (2250 min = 37 h 30 min)
\(=\)
Monday (450 min)
\(+ \cdots +\)
Friday (450 min)
\(S = 450 \times 5 = 2250\)
\(H = 2250 \div 60 = 37.5\)
Key idea
Add only the days you worked (a day off counts as 0 minutes).
When you use "37 hours 30 minutes" to calculate pay, the most common mistake is to write it as "37.3 hours". Thirty minutes is half an hour, \(0.5\) hours, so 37 hours 30 minutes is \(37.5\) hours. "Divide the minutes by 60 to get a decimal" is the whole idea of decimal hours. If the minutes do not divide evenly by 60, the decimal goes on forever, so this calculator shows the value rounded to 2 decimal places.

\(=\)

hourly wage ($18)
\(P = 37.5 \times 18 = 675\)
Key idea
The pay on this page is an estimate from one simple multiplication: total hours (decimal hours) × hourly wage. When the numbers do not come out even (when the decimal hours shown are rounded, or when the pay has a fraction of a cent), the pay is rounded to the nearest cent and shown with "≈" instead of "=".
Overtime is not included. In the US, hourly workers generally earn 1.5 times their regular rate for hours over 40 in a workweek under the federal Fair Labor Standards Act (FLSA), and some states add their own rules. Shift differentials and deductions such as taxes are not included either. Check your actual pay on your pay stub.
The basic method for a time card is: for each day, find the hours worked as clock-out − clock-in − break, then add up all the days you worked. Divide the weekly total in minutes by 60 to get decimal hours (such as 37.5 hours), and multiply by your hourly wage to estimate your pay.

Terms
| time card | A card or system that records the clock-in and clock-out times for each day. The recorded times are added up into hours worked, which are the basis for payroll. This page adds up one week of a time card at once. |
| timesheet | A record of when you worked - clock-in, clock-out, breaks and days off - for a pay period. Adding up a timesheet means turning the recorded times into total hours worked. |
| hours worked | The time from clock-in to clock-out minus the break, the time you actually worked. For hourly workers, pay is normally based on these hours. (Unpaid meal breaks are taken out; short rest breaks are usually counted as paid time.) |
| decimal hours | Time written as a decimal, such as 37 hours 30 minutes = 37.5 hours. The minutes are divided by 60, so the value can be multiplied by an hourly wage as is. Note that 37 hours 30 minutes is not 37.3 hours. |
| overnight shift | A shift during which the date changes, such as a night shift. The clock-out time is a smaller number than the clock-in time, so one day, 1440 minutes, is added in the calculation. |
| overtime pay | Pay at a higher rate than the regular hourly wage. In the US, the federal Fair Labor Standards Act (FLSA) generally requires 1.5 times the regular rate for hours over 40 in a workweek for non-exempt workers, and some states also count daily overtime. Extra pay for night shifts (a shift differential) is usually set by the employer. The conditions and rates depend on the law and your employer, so this calculator leaves them out and only calculates total hours × hourly wage. |

In the first table, enter each day's clock-in and clock-out times (such as "9:00") and break in minutes in columns B to D, and column E shows the minutes worked that day. IFERROR(TIMEVALUE(cell),cell) turns a time into a number (where 1 day = 1). It works both when the cell holds text such as "9:00" and when Excel already treats the cell as a time. MOD(clock-out − clock-in, 1) handles overnight shifts: when the subtraction is negative (clocking out the next day), it adds one day. The difference is multiplied by 1440 to get minutes, and then the break is subtracted. Rows with blank clock-in or clock-out stay blank and are not counted. In this example, Monday to Friday are 450 minutes each, and the weekly total in E9 is 2250 minutes.
In the second table, enter the weekly total in minutes in B1. B2 and B3 split it into 37 hours 30 minutes with QUOTIENT (the whole-number part of a division) and MOD (the remainder), and B4 shows the decimal hours (37.5; ROUND rounds to 2 decimal places when the division does not come out even). Enter your hourly wage in B5, and B6 shows the estimated pay ($675.00 in this example, rounded to the cent). Just replace the values in column B with your own.

TIMEVALUE (turns time text into a number), IFERROR (returns another value if there is an error), IF (a condition), QUOTIENT (the whole-number part of a division), MOD (the remainder) and ROUND (rounding) are written the same way in Google Sheets as in Excel. Google Sheets turns a pasted "9:00" into a time automatically, but thanks to the IFERROR fallback the formula works either way. Copy the whole table, paste it into cell A1, and replace columns B to D with your own times. The answers are the same as in Excel.

return hour * 60 + minute
def format_minutes(total_minutes):

hours, minutes = divmod(total_minutes, 60)
if hours == 0 and minutes == 0:
return "0 h"
if hours == 0:

return f"{hours} h {minutes} min"
total_work = 0
for day_name, clock_in, clock_out, rest_minutes in week:
elapsed = to_minutes(clock_out) - to_minutes(clock_in)
if elapsed < 0:
# clock-out is earlier than clock-in -> clocked out the next day (overnight shift), so add one day
elapsed += 1440
work = elapsed - rest_minutes
total_work += work
print(f"{day_name}: {format_minutes(work)}")
decimal_hours = round(total_work / 60, 2) # decimal hours (for hourly pay)
print(f"Weekly total: {format_minutes(total_work)} ({decimal_hours} h, {len(week)} days)")
if hourly_wage is not None:
pay = round(total_work * hourly_wage / 60, 2) # estimated pay (rounded to the cent)
print(f"Estimated pay: ${pay:,.2f}")
Runs with the standard library only. divmod returns the quotient and the remainder of a division at the same time, so dividing minutes by 60 splits them into hours and minutes.
Change week at the top (the clock-in, clock-out and break for the days you worked) and the hourly wage, then run the code.

How to have ChatGPT do the calculation
You are a timesheet calculation assistant. Do the following calculation by actually running Python code, and base your answer only on the numbers from the execution result (do not answer by mental math or guessing). Here is one week of a time card. All times are on the 24-hour clock, and breaks are in minutes. - Monday to Friday: clock in 9:00, clock out 17:30, 60-minute break - Saturday and Sunday: no work The hourly wage is $18. Find each of the following: 1. The hours worked each day (in the form "X hours Y minutes" for each day) 2. The total hours worked in the week (in the form "X hours Y minutes") and the number of days worked 3. The weekly total in decimal hours (the total minutes worked divided by 60) 4. The estimated pay (decimal hours × hourly wage, rounded to the cent, with no overtime or deductions) Find each day's hours worked as (clock-out in minutes) − (clock-in in minutes) − break. If the clock-out time is earlier than the clock-in time on any day, treat it as clocking out the next day (overnight) and add 1440 minutes. Show the formulas you used and the numbers from the execution result.
