calculating is too slow in my excel sheet

[belal]

first of all, i have to admit that i learn many issues in excel from this site so i have to say thanks a lot..keep it up

Second, i have major problem in my excel which can be concluded in slow calculating ( on other words, every time i try to update or modify in sheet excek took long time in calculating like this (calculating : 4 processor ..19% ) ...my excel sheet include many functions like index & Sumif & vlookup & match & pivot table & If error and for sure all this function may be mixed in one cell...so what shall i do ? i search a lot and made several tries as i read it on web sites like give excel sheet high priorities and make calculation manual and this option i don't like it as it will not help me in my work

my excel sheet have several tabs and it's size around 14.5Mega and my laptop specification is below :
Model :hewlett-packrad HP Probook 4540s
Processor : Core I5-3210M CPU @2.5 GHz
Ram :4 Giga ( 2.63 GB useable )
System type : 32- bit
Microsoft office professional plus 2013

Hi belal,

Did the slow calculation steadily creep in or was it running OK one day then suddenly became slow?

Try to switch to a faster VLOOKUP set up; eliminate IFERROR calls; avoid if possible OFFSET and INDIRECT calls if you have them...

it was going smooth but i updated more data and make more coloums and rows so it became too slow even if i clear the filter this calculation appear

kindly could you explain what do you mean with faster vlookup ? and i can't elinate iferror as i made it to disappear N/A and replace it with zero...on other hand,,,i don't know what do you mean with offset and indirect calls so i don't think i use it :D

Hi belal

Do you have any macro code in your workbook at all? Where is the data coming from?

i didn't use macro in this sheet..some data from outside and almost of it from inside the sheet

Care to post the VLOOKUP formula that you have to invoke too many times?

 

[belal]

kindly find the most equation i used in the sheet

=IFERROR(VLOOKUP($A16,'No# Cst & Mnths'!A13:CE40,MATCH(C$2,'No# Cst & Mnths'!$A$1:$CE$1,0),FALSE),0)
=IF(ISERROR((C84-B84)/B84),"100%",((C84-B84)/B84))
=SUMIF('Budget TB'!$C$7:$C$944,'DashBoard Presentation'!$A68,INDEX('Budget TB'!$C$7:$DH$944,0,MATCH(C$2,'Budget TB'!$C$1:$DH$1,0)))
=(SUMIF('2015 Vs 2014 Vs 2013'!$C$2:$C$7498,$B93,INDEX('2015 Vs 2014 Vs 2013'!$A$2:$BZ$7498,0,MATCH(C$81,'2015 Vs 2014 Vs 2013'!$A$1:$BZ$1,0))))*-1

These do not appear as formulas that would consume significant temporal resource.

1. Sort A13:CE40 on A13:A40 in ascending order and keep this sorted.

2. Name A1:C40 CstMonths.

3. Invoke:

=VLOOKUP($A16,CstMonths,MATCH(C$2,INDEX(CstMonths,1,0),0),1)

in lieu of:

=IFERROR(VLOOKUP($A16,'No# Cst & Mnths'!A13:CE40,MATCH(C$2,'No# Cst & Mnths'!$A$1:$CE$1,0),FALSE),0)

4. Invoke:

=LOOKUP(9.99999999999999E+307,CHOOSE({1,2},100%,(C84-B84)/B84)

in lieu of:

=IF(ISERROR((C84-B84)/B84),"100%",((C84-B84)/B84))

5. In a convenient cell of DashBoard Presentation, say in X2, enter the following:

=MATCH(C$2,'Budget TB'!$C$1:$DH$1,0)

and now invoke on DashBoard Presentation:

=SUMIFS(INDEX('Budget TB'!$C$7:$DH$944,0,$X$2)'Budget TB'!$C$7:$C$944,$A68,)

in lieu of:

=SUMIF('Budget TB'!$C$7:$C$944,'DashBoard Presentation'!$A68,INDEX('Budget TB'!$C$7:$DH$944,0,MATCH(C$2,'Budget TB'!$C$1:$DH$1,0)))

6. Adapt the (5) scheme for the last formula you posted.
