Dashboard Mode - ROUND, ROUNDUP, ROUNDDOWN

Dashboard Goal

Understand how to round numbers in different ways using ROUND, ROUNDUP, and ROUNDDOWN functions in Excel. This dashboard shows how these functions change numbers and helps decide which to use for your needs.

Sample Data

Item	Original Number
Price A	12.345
Price B	7.891
Price C	3.456
Price D	9.999
Price E	15.123

Dashboard Components

• KPI Cards: Show rounded results for Price A using each function:
  ROUND: =ROUND(B2,2) -> 12.35
  ROUNDUP: =ROUNDUP(B2,2) -> 12.35
  ROUNDDOWN: =ROUNDDOWN(B2,2) -> 12.34
• Rounded Table: Shows all prices rounded to 1 decimal place:
  ROUND: =ROUND(B2,1)
  ROUNDUP: =ROUNDUP(B2,1)
  ROUNDDOWN: =ROUNDDOWN(B2,1)
• Summary Table: Average of original and rounded numbers:
  Average Original: =AVERAGE(B2:B6) -> 9.763
  Average ROUND: =AVERAGE(C2:C6) -> 9.8
  Average ROUNDUP: =AVERAGE(D2:D6) -> 9.8
  Average ROUNDDOWN: =AVERAGE(E2:E6) -> 9.7

Interactivity

Add a filter to select specific items (e.g., Price A, Price C). When you select items, the KPI cards, Rounded Prices Table, and Summary Table update to show rounded values only for the selected items. This helps compare rounding effects on chosen numbers.

Self Check

If you filter to show only Price D and Price E, which KPI card shows the highest average rounded value?

Answer: The ROUNDUP KPI card shows the highest average because ROUNDUP always rounds numbers up, making values larger.
