Multiple If True Values - IF Function Excel

[hue]

Not an expert so I need allot of help. In a production schedule I have various models to make with X number of units per model in a day. Using VLOOKUP I have a time value (production time) column for each model multiplied by its number of units, so I know the time it takes to produce each individual model in a day. I now need to include a PST (Production Standard Time) column for each model so workers can know at what time they should finish each of the models in the daily schedule. During our work hours (7:00am - 5:06pm) I have 3 lunch/rest breaks one @ 9:20 am(lasts 19min), 12:30 pm(lasts 29min) and 3:00 pm(lasts 9min) so I need to add to the PST that specific lunch/rest time if a model is finished during any of the lunch/rest periods, so I’ll assure the PST is accurate. How can achieve this using one single formula, considering the 3 criteria?

Criteria #1: IF((A1+B1)>=timevalue("9:20 am") but <=timevalue("12:30 pm"), (A1+B1)+time(0,19,0), (A1+B1))
Criteria #2: IF((A1+B1)>=timevalue("12:30 pm") but <=timevalue("3:00 pm"), (A1+B1)+time(0,29,0), (A1+B1))
Criteria #3: IF((A1+B1)>=timevalue("3:00 pm"), (A1+B1)+time(0,9,0), (A1+B1))

Since the values will be adding up as the day goes, it can occur, that the value (A1+B1) falls directly into the second criteria (eg. 1:37 pm), I need then for it to add the 29 minutes plus the 19 of the first criteria, and so on and so forth. Thanks so much in advance.

Actually, what you want is something slightly different than what you have stated.

For the 2nd break you don't want to check if A1+B1>12:30 but if A1+B1+1st break > 12:30! The same concept applies to the 3rd break.

Here's what you should use
=A1+B1+IF(SUM(A1:B1)>=TIMEVALUE("9:20:00"),TIME(0,19,0),0)+IF(SUM(A1:B1)>=TIMEVALUE("12:30:00")-TIME(0,19,0),TIME(0,29,0),0)+IF(SUM(A1:B1)>=TIMEVALUE("15:00:00")-TIME(0,19,0)-TIME(0,29,0),TIME(0,9,0),0)

Dear tusharm,

I apreciate your time and efforts to help with this issue. I inform you that it seems to work but at a certain point it just doesn't, hope with this image/example I can explain the situation:

What you are doing is different from what you described! Consequently, I suspect that the way you adapted the formula for your specific scenario, you are double-counting all breaks starting with row 5.

Start with G2: Wherever I used A1+B1, or SUM(A1:B1) -- and which you adjusted appropriately, replace those terms with TIME(7,0,0)+SUM($D$2:$D2) -- note there is 1 $ missing!.

Better yet, put the start time in some cell and replace all references to TIME(7,0,0) with an absolute reference to that cell.

Now, copy G2 as far down column G as needed.

tusharm,

You are the best! it worked! to perfection. I really appreciate your expertise, time and effort on this issue, it will will help me super. I give you the formula as it was finalized and according to me at it's minimal expression:

=TIME(7,,)+SUM($I$6:I6)
+IF(TIME(7,,)+SUM($I$6:I6)>=TIME(9,20,),TIME(,19,),)
+IF(TIME(7,,)+SUM($I$6:I6)>=TIME(12,30,)-TIME(,19,),TIME(,29,),)
+IF(TIME(7,,)+SUM($I$6:I6)>=TIME(15,,)-TIME(,19,)-TIME(,29,),TIME(,9,),)

tusharm,

Hi, hope you are fine, I have a couple of questions, if you have time, I'll apreciate it if you can look at the image and offer a coment:
