Excel's PERCENTOF function returns the percentage that a subset of data contributes to a whole dataset, saving you from having to create additional or complex formulas to generate the same outcome.

If using a calculator, you can calculate one number as a percentage of another by dividing the numbers and multiplying by 100. Find 23 as a percentage of 80. Calculate \(23 \div 80 = 0.2875\).
