Hi,
For Sumproduct have a look he- http://www.xldynamic.com/source/xld.SUMPRODUCT.html and for help on array formula http://www.cpearson.com/excel/ArrayFormulas.aspx Mike "Srikanth" wrote: Hi, Can any one explain me what is sum product and how does it works...

... Hi, Can any one explain me what is sum product and how does it works... And also the array.... Thanks in advance... Let's take a simple example: =SUMPRODUCT(A1:A5,B1:B5) This takes the product of each corresponding pair of values and then sums these. In other words, it calculates A1xB1 + A2xB2 + A3xB3 + A4xB4 + A5xB5 It is often used for summing data subject to one or more conditions. In its simplest form, this is equivalent to SUMIF. For example: =SUMPRODUCT(--(A1:A5="dog"),B1:B5) will sum data in column B where the corresponding entries in column A are "dog". The bit with --( ) merely converts TRUE/FALSE to 1/0, which can be used in calculating the products. The great advantage over SUMIF is that multiple conditions are possible, such as =SUMPRODUCT(--(A1:A5="dog"),--(B1:B5="black"),C1:C5) The arrays must all be the same size but do not need to be in adjacent columns, for example: =SUMPRODUCT(--(F4:F99910),--(D4:D999="abcde"),--(X4:X999<Sheet2!G7),--(J4:J999<=500),F4:F999,M4:M999) will give the sum of product pairs in rows 4 to 999 of columns F and M where all of the following conditions are satisfied: column F is greater than 10; column D contains text "abcde"; column X does not equal whatever is in cell G7 of Sheet2 column J is less than or equal to 500. It's a very useful and versatile function. Post back if you have specific questions. |

Hi Stephen,
I dint get the following formulae. It is often used for summing data subject to one or more conditions. In its simplest form, this is equivalent to SUMIF. For example: =SUMPRODUCT(--(A1:A5="dog"),B1:B5) will sum data in column B where the corresponding entries in column A are "dog". The bit with --( ) merely converts TRUE/FALSE to 1/0, which can be used in calculating the products. Can u eloborate this by giving an easy example. "Stephen" wrote: "Srikanth" wrote in message ...

Suppose this is the data in A1:B5:
dog 1 cat 2 dog 3 dog 4 bird 5 The formula =SUMPRODUCT(--(A1:A5="dog"),B1:B5) will give the result 8, the total of column B where corresponding entries in column A are "dog". It works like this: = 1*1 + 0*2 + 1*3 + 1*4 +0*5 The first number in each pair is 1 (if column A = "dog") or 0 otherwise. The second number is the data from column B. "Srikanth" wrote in message ...
