In most formulas, you wouldn’t notice the difference Excel simply evaluates the reference and returns the value.
This formula uses this feature to construct a dynamic range based on worksheet input.
The formula in J8 is almost the same but usesAVERAGEinstead ofSUMto calculate an average.
When a user changes values in J5 or J6 the range is updated, and new results are returned.
However, OFFSET is avolatile functionand can cause performance problems when used in larger, more complex worksheets.
you’re able to use INDEX to retrieve individual values, or entire rows and columns.
OFFSET is handy in formulas that require a dynamic range.
