    Question Help with conditional time subtraction

    I need a formula please to display a result as follows:

    If time sum of cell L61-98:00 resulted in a time more than 20:00 hours.
    The formula should display please the extra time in hours and minutes over the 20:00 hours multiply by 1.5 plus the original 20:00 hours.
    If cell L61 contains 98:00 hours or less, to display the hours and minutes over 78:00 only.

    Example:
    If Cell L61 has a time of 102:00
    The end result formula should display 26:00

    If Cell L61 has a time of 95:00
    The result should be 17:00

    Try this...

    =IF(OR(ISTEXT(L61),L61=""),"",IF(L61>98,(L61-98)*1.5+20,20-(98-L61)))

    Re: Help with conditional time subtraction

    102:43-98:00=4:43
    4:43*1.5=7:04
    20+7:04=27:04

    Re: Help with conditional time subtraction

    Try this revised formula...

    =IF(OR(ISTEXT(L61),L61=""),"",IF(VALUE(TEXT(L61,"[h].m"))>98,(VALUE(TEXT(L61,"[h].m"))-98)*1.5+20,20-(98-VALUE(TEXT(L61,"[h].m")))))

    Re: Help with conditional time subtraction

    Attach a sample workbook. Make sure there is just enough data to make it clear what is needed. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are demonstrated, mock them up manually if needed. Remember to desensitize the data.

    Click on GO ADVANCED and use the paperclip icon to open the upload window.

    Re: Help with conditional time subtraction

    I believe your last formula could be right but it has unsupported function by my apple app I am using to work with my excel sheet.

    Below is a link for the supported functions,
    http://support.dataviz.com/support.srch?docid=2310

    Would you please replace the function in the last formula with a supported one.

    Thank you

    Re: Help with conditional time subtraction

    In K60 Cell-Supporive Cell

    =IF(OR(ISTEXT(L61),L61=""),"",IF(VALUE(TEXT(L61,"[h].m"))>98,(VALUE(TEXT(L61,"[h].m"))-98)*1.5+20,20-(98-VALUE(TEXT(L61,"[h].m")))))

    In K61 Cell

    =VALUE(INT(K60)+INT(INT((K60-INT(K60))*100)/60)&"."&TEXT(MOD(INT((K60-INT(K60))*100),60),"00"))

    Format both the cells as General
