In this article, we will show you the Excel formula to calculate hours worked minus lunch. Lunchtime can be in hours or it can be expressed as in starting and ending time. Based on different scenarios the formulas will be applied which will give you the number of hours worked excluding lunchtime.

## How to Calculate Hours Worked Minus Lunch Using Formula in Excel: 4 Ways

Here, we have the following dataset containing the records of Start Time, End Time, Lunch Start time, and Lunch End time of some working days. Using this dataset we will calculate the working hours for these days. For completing this article, we have used the Microsoft Excel 365 version, but you can use any other version at your convenience.

### Method-1: Using SUM Function to Calculate Hours Worked Minus Lunch Showing Result in Hour Format in Excel

We will work here in 2 times format. In each case, the lunch starts and lunch ends at the time given. You will get the hours results in fractions like 8.25, 7.75, etc. Don’t get confused if you find these fraction numbers. As we will find the differences at some different times, the fractional result is expected. The 8.25 means 8 hours 15 minutes whereas 7.75 means 7 hours and 45 minutes. In the same way, 8.50 means 8 hours 30 minutes. The formulas for calculating the number of working hours are placed for two different time formats. You will get the same results from both formats. For this method, we will be using the SUM function.

#### 1.1. Showing 12-Hour Format

Here, we will be working with the times in 12 hours time format, which is AM/PM time formatting. • Type the following formula in cell G4.
`=SUM((D4-C4)+(F4-E4))*24`

Also, this formula can be written as the following.

`=SUM((F4-C4)-(E4-D4))*24`
• Drag down the Fill Handle In this way, we will get the total working hours for the working days. #### 1.2. Showing 24-Hour Format

In 24-hour time format, the 13:30 time formatting is applied without the Working Hours column. • Enter the following formula in cell G4.
`=SUM((D4-C4)+(F4-E4))*24`
• Drag down the Fill Handle Afterward, we will get the total working hours for the working days. ### Method-2: Using MOD Function

In this section, we are going to use the MOD function to calculate the working hours after subtracting the total hours from the lunch hours. • Use the following formula in cell G4.
`=MOD(F4-C4,1)-MOD(E4-D4,1)`

Formula Breakdown

• F4-C4 → becomes
• 75-0.375 → 0.375
• MOD(F4-C4,1) → becomes
• MOD(0.375,1) → returns a remainder after dividing 375 by 1.
• Output → 0.375
• E4-D4 → becomes
• 58333-0.5416667 → 0.04166667
• MOD(E4-D4,1) → becomes
• MOD(0.04166667,1) → returns a remainder after dividing 04166667 by 1.
• Output → 0.04166667
• MOD(F4-C4,1)-MOD(E4-D4,1) → becomes
• 375-0.04166667
• Output → 8.00 AM
• Drag down the Fill Handle. As a result, the working hours will be displayed in the following time formats which we will change to show the differences. • Select the range of the working hours and then press CTRL+1. Afterward, the Format Cells dialog box will appear.

• Select Time as Category, 13:30 as Type.
• Press OK. The final results will be like the following figure. ### Method-3: Calculate Hours Worked Minus Lunch Showing Result with Hours and Minutes in Excel

To avoid the fraction numbers, you can display your results as Hours and Minutes together. For this, you need an extra formula. Before that, we will use the previous formula in Method-1 to calculate the total working hours. After that, we will do some formatting using the INT, and TEXT functions. The formulas are the same for both 12-hour and 24-hour format styles. • Follow Method-1 to fill up the Working Hours column with the formula. • In cell G4, apply the following formula for formatting.
`=INT(F4)&" Hrs."&" "&TEXT((F4-INT(F4))*60,"0")& " Mins."`

Formula Breakdown

• INT(F4) → becomes
• INT(8) → 8
• INT(F4)&” Hrs.” → becomes
• 8&” Hrs.”
• Output → ” 8 Hrs.”
• F4-INT(F4) → becomes
• 8-8 → 0
• TEXT((F4-INT(F4))*60,”0″) → becomes
• TEXT(0,”0″) → 0
• INT(F4)&” Hrs.”&” “&TEXT((F4-INT(F4))*60,”0″)& ” Mins.” → becomes
• ” 8 Hrs.”&” “&0& ” Mins.”
• Output → 8 Hrs. 0 Mins.
• Drag down the Fill Handle Finally, you will have the following result. ### Method-4: Applying Formula to Calculate Working Hours When Lunch Hour Is Given

Instead of Lunch Starts and Lunch Ends time, only the Lunch Time (In Hours) can be given. In this case, showing the hours of work becomes difficult due to the formatting. To avoid this problem follow the below procedure. • Enter the following formula in cell F4.
`=(E4-C4)-D4`
• Drag down the Fill Handle As a result, you will see the working hours in the following time formats which we will change to show the differences. • Select the range of the working hours and then press CTRL+1. Afterward, the Format Cells dialog box will appear.

• Select Custom under the Category section and write down h” Hrs. and “m” Mins.” In the Type
• Press OK. Afterward, you will have the following results in the Total Time column. ## Practice Section

1. Reply People normally pay me for this and you are giving it away!

2. Reply This is a lot of detail, well done.

Only problem is, you’re not showing the formula for the F column – Excel doesn’t handle sum/subtraction for time correctly on its’ own.

• Reply Thanks.

3. Reply I have taken several of your courses and really appreciate these frequent tips. Excel is so powerful and extensive that I doubt I will ever use it to its potential but I do appreciat these insightful learning aids. Thank you so very much!

Hi there this is the most easy to follow advice out there so thankyou so much, please can I ask when you have a start time, total lunch time and end time and then the total hours and minutes worked such as =(E3-C3)-D3, how to I convert this into a fraction> You do have have this as a end formual above where you have start time, start lunch, end lunch and end time and the end formual is worked out in hours like 6.75hrs etc, but I need it when I only have start and finidhs time and, lunch break total – any advice most welcome 🙂
