Subtracting a varied break times on a time sheet.


I need help, I am doing a time sheet that contains shift work and allowances and lunch times that vary.

The formula I have which allows me to manually input the break times is :

  • Start time D6
  • Breaks E6 .... needs to be manually entered as it can vary from 30min to 1.5 hours
  • Finish time F6

=ROUND((IF(OR($D$6="",$F$6=""),0,IF($F$6<$D$6,$F$6+1-$D$6,$F$6-$D$6))-$E$6/1440)/(1/1440),0)*(1/1440)    this works fine,

but then I have a formula for shift allowance


which adds up fine too but I need to add a formula for (breaks) E6 to the shift allowance  formula

are there any solutions.... please



I would use a Date/Time format (e.g 5/22 14:00) for start/end times and a simple time format (e.g 0:30) for the break time which would eliminate much of the complexity of your first formula. It would then simply be =F6-E6-D6. As for the second formula for shift allowance, I'm a bit lost. My understanding of shift allowance is to pay more for off shifts. Is that the goal here?

thankyou for reminding me KISS is better ( Keep it sort and simple) 
I simplified the first formula to 
 =MOD(F6-D6-E6,1)*24    as there are Day, Afternoon and Night shifts I added the MOD function and it works. As for the 2nd formula, we get paid and allowance for different shifts EG:
Afternoon shift from 14:30 to 21:30 we are paid and additional 12.5% and an 15% for night shift 21:30 to 7:00 on top of my base wage rate less breaks. So I left the 2nd formula almost the same just minused E6
and it works too only now the cells that do not fall within this range so ########## and a message saying negitave times are to long, not sure how to add the mod function to this formula,
any idias please.

I would like to see a current version of the template you use where you show your inputs with desired results and the current formulas that you use.

sorry I have tried to copy and paste but this is not allowing me to.

To do that, you edit your question and upload an Excel file with the template in it.

Hi, I have uploaded the file as you said.... thankyou again for explaining what to do..
some how I need to get the formula to work on 24hrs as the above formula with spicific times does not work in the night shift column "21:30""7:00"
Ps I uploaded the file on the first question asked...

i'm more the fan of Decimal time (8:15am = 8.25; 3:45 pm = 15.75) as long as things are worked out in quarter of hours, like :15, :30 & :45 (.25, .5, .75), unless individuals work past keeps things simple
