where total is the named range D15 and column C contains decimal values with the percentage number format applied. Note: in the example, the percentage values in column C are unrounded decimal numbers like 0.359897172, which accounts for the 0.20 difference in the calculation above. The total of all expenses is in cell D15, which is also the named range “total”. To perform this calculation in Excel, we simply multiply the percentage in column C by the total in cell D15. The formula in D6, copied down is: Named ranges behave like absolute references by default, so the equivalent formula without a named range  is: For each expense in the table, Excel returns a calculated amount.

Formatting percentages in Excel

In mathematics, a percentage is a number expressed as a fraction of 100. For example, 85% is read as “Eighty-five percent” and is equivalent to 85/100 or 0.85. Accordingly, the values in column C are decimal values.  For example, C6 is approximately 0.36, C7 is approximately 0.18, etc. To display these numbers as a percentage with the percent sign (%), the Percentage number format has been applied to C6:C13.
