Using SUM With Other Data Types
SUM is a very precise function and will not work with data types other than numbers.
To get intended results, you will need to use numbers.
Check out the below example to see what happens when you use dates!
Date Data:
Excel treats dates as numbers.
Because of this, you will get unintended outcomes when adding up dates.
Simple Example
Imagine you want to add up your daily expenses.
Select the cells with your expense amounts, then use the SUM function:
=SUM(A2:A5)This formula adds up the values from cell A2 to A7.
Advanced Example
Let’s combine SUM with IF to sum only certain expenses.
Suppose you only want to add expenses over £50:
=SUMIF(A2:A5,">=50",A2:A5)This formula sums values in A2:A5 that are greater than $50.
You can even use the SUM function to create a data model in Excel!
Troubleshooting & Errors
Let’s take a look at some common errors you may run into when using the SUM function.
Error 1: #VALUE! Error
Cause: Mixing data types like text and numbers in the sum range.
Solution: Ensure all cells in the range contain numeric values.
Error 2: Unexpected Results with Dates
Cause: Summing date-formatted cells directly.
Solution: Convert dates to numbers using DATEVALUE before summing.
What Is The SUM Function Useful For?
The SUM function is a fundamental tool to Excel, and it can be used for plenty of work.
| 1. Data Validation: | Ensures data integrity by checking the sum of a range against expected totals. |
| 2. Basic Statistical Analysis: | Quickly calculates total values, an essential step in many statistical methods. |
