For eg. If you have student database and now you want to calculate the weighted average with the help of SUMPRODUCT function then you just take few important given steps:

Step 1: Prepare the worksheet as per given below:
Step 2: There are two methods from which you can easily calculate Final Grade of student database: Method 1: If you want to calculate the Final Grade of student database with the help of SUMPRODUCT function then take the cursor on cell B10 and type this formula: =SUMPRODUCT(B2:B9,C2:C9). It will shows you same result 6525.

Method 2: Type the following given formula in Cell B12: =(B2*C2)+(B3*C3)+(B4*C4)+(B5*C5)+(B6*C6)+(B7*C7)+(B8*C8)+(B9*C9) and then press Enter. It will shows you 6525 as a result.

Step 3: If you want to calculate weighted average then again you have to two methods.

Method 1: If you want to calculate the weighted average from SUMPRODUCT function, take the cursor on cell B11 and apply this formula: =SUMPRODUCT(B2:B9,C2:C9)/SUM(C2:C9). After pressing enter you will get 87 as a result.

Method 2: Take the cursor on cell B13 and apply this formula: =((B2*C2)+(B3*C3)+(B4*C4)+(B5*C5)+(B6*C6)+(B7*C7)+(B8*C8)+(B9*C9))/(C2+C3+C4+C5+C6+C7+C8+C9). After pressing enter you will get 87 as a result.
