CSR Reporting I Using Excel SUMPRODUCT

Example of SUMPRODUCT function in Excel used for an example from Social Sector. 

Let us assume, that as a funding company your donations for a month are as per the table given below. 

Amount in Rupees

Description

25,000 

Covid Relief - PPE kits

10,000 

Covid Relief - Grocery kit 

40,000 

Covid Relief - Grocery kit 

20,000 

General Donation for healthcare activities

44,000 

Medical Assistance 

3,50,000 

Covid relief activities

10,000 

General donation 

6,000 

Monthly aid

89,600 

50% advance for supply of medicines

5,00,000 

Covid relief activities

4,980 

Supply of groceries to tribal children

5,00,000 

Relief activities for Covid

49,450 

Scholarship

22,166 

Scholarship


Your manager wants to know the spend on covid relief related activities for that particular month.

Now let us find out how SUMPRODUCT function can do the conditional sum. The Excel SUMPRODUCT function multiplies ranges or arrays together and returns the sum of products.

The expression to use is =SUMPRODUCT(Table1[Amount]*--(ISNUMBER((SEARCH("covid",Table1[Purpose],1))))). Where the dataset has a name of Table1.

If the term covid is found, the search function returns a number indicating its position. ISNUMBER function then would return True. The double negative forces True and False to 1 and 0 for doing the multiplication. Then the addition. 

=SUMPRODUCT(Table1[Amount]*(ISNUMBER((SEARCH("COVID",Table1[Purpose],1))))) is similar to the above formula. 

Thus, to recap, wherever the word covid is found, the function returns “True”, and the corresponding amount is multiplied by 1. All such amounts are added. The search term “covid” is not case sensitive. You can use “COVID” as well. The answer is Rs 14,25,000. 

Similarly formula =SUMPRODUCT(Table1[Amount]*--(ISNUMBER((SEARCH("Scholarship",Table1[Purpose],1))))) can be used to calculate donations given as Scholarships. The answer is Rs 71,616.

In my next blog, I will add another dimension of time to calculate the conditional sum.

Very thorough yet not verbose! Think I learnt something new today, great job! Waiting for your next post with the time dimension coming in!
