Calculate Hours of Work Where Only Hours will be Displayed

I will work here with 2 times format. In each case, the lunch starts and lunch ends time is given. You will get the hours results in fractions like 8.25, 7.75 etc. Don’t get confused if you find this 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 where 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 the formats.

12 Hour Time Format

In 12 hours’ time format, the AM/PM time formatting is applied without the Total Time of Works (Hrs.) column. The formula which is applied here is =SUM((D3-C3)+(F3-E3))*24. You can also apply the formula =SUM((F3-C3)-(E3-D3))*24 which will give you the same result.

24 Hour Time Format

In 24 hours’ time format, the 13: 30-time formatting is applied without the Total Time of Works (Hrs.) column. The formula which is applied here is =SUM((D3-C3)+(F3-E3))*24. You can also apply the formula =SUM((F3-C3)-(E3-D3))*24 which will give you the same result.

Calculate Hours of Work Where Hours and Minutes will be Displayed

To avoid the fraction numbers, you can display your results as Hours and Minutes together. For this, you need an extra formula. Before that, use the previous formulas to calculate the total hours of work in hours. Here the formatting of 12 hours and 24 hours are formatted as before. I am showing you the 12 hours format style. The formula is the same for both.

In the above picture, the hours of work calculated using the formula, =SUM((D3-C3)+(F3-E3))*24 in the Total Time of Work (Hrs.) column. To display it as hours and minutes the formula, =INT(G3)&” Hrs.”&” “&TEXT((G3-INT(G3))*60,”0″)& ” Mins.” was used.

Display Hours and Minutes of Work Where 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.

  • In cell F3, write down the formula =(E3-C3)-D3.
  • Now, double-click on the fill handle to copy this formula for the rest of the cells of the column.
  • After this, select the cells where this formula is applied and press on to the right button of your mouse to select the Format Cells option.
  • In the Format Cells dialogue box, select Custom under the Category section and write down h" Hrs. and "m" Mins." In the Type section.

  • Now after pressing OK, you will get to see the below result.
