Calculate total sales from a pivot table

You have a pivot table summarizing sales by product and region. The cell B5 shows the total sales for Product A in Region 1. Which formula correctly sums all sales for Product A across all regions?

A =SUM(B5:E5)

B =SUM(B5:B10)

C =SUM(B2:B5)

D =SUM(B5:E10)

💡 Hint

Look at the row for Product A and sum across the columns representing regions.

The sales for Product A are in row 5 across columns B to E, so summing B5:E5 adds all regions for Product A.

❓ Function Choice

Choose the correct function to count unique customers in a pivot table

You want to count how many unique customers bought Product B in all regions using a pivot table. Which function should you use in Excel or Google Sheets?

A COUNT()

B COUNTUNIQUE()

C COUNTA()

D SUM()

💡 Hint

Think about counting distinct or unique values.

COUNTUNIQUE() counts unique values, which is needed to count distinct customers.

Identify the region with highest total sales from pivot data

Given a pivot table with total sales per region in cells B2:B6, which formula returns the name of the region with the highest sales if region names are in A2:A6?

A =INDEX(A2:A6, MATCH(MAX(B2:B6), B2:B6, 0))

B =VLOOKUP(MAX(B2:B6), A2:B6, 2, FALSE)

C =MAX(A2:A6)

D =MATCH(MAX(B2:B6), A2:A6, 0)

💡 Hint

Use MATCH to find position of max sales, then INDEX to get region name.

MATCH finds the row of max sales in B2:B6, INDEX returns the region name from A2:A6 at that row.

🎯 Scenario

Filter pivot table data dynamically

You want to create a formula that sums sales for Product C only in regions where sales are greater than 1000, using pivot table data in B2:E6 (products in rows, regions in columns). Which formula achieves this?

A =SUM(B4:E4>1000)

B =SUMIF(B4:E4, ">1000")

C =SUMIFS(B4:E4, B4:E4, ">1000")

D =SUMPRODUCT((B4:E4>1000)*B4:E4)

💡 Hint

Use SUMPRODUCT to multiply condition by values for conditional sum.

SUMPRODUCT multiplies the condition (TRUE=1, FALSE=0) by sales values, summing only those >1000.

Determine the output of a complex pivot table formula

Given a pivot table with sales data in B2:E6 and product names in A2:A6, what is the result of this formula: =SUMPRODUCT((A2:A6="Product D")*(B2:E6))?

A Error due to mismatched ranges

B Sum of all sales in the table

C Sum of all sales for Product D across all regions

D Sum of sales for all products except Product D

💡 Hint

Check how the condition filters rows and how SUMPRODUCT sums matching rows.

The condition (A2:A6="Product D") creates an array with 1 for Product D row and 0 elsewhere. Multiplying by B2:E6 sums only Product D sales.
