Common-size ratio

Definition

A common-size ratio is a financial analysis tool that expresses each line item in a financial statement as a percentage of a base item, typically total revenue for the income statement and total assets for the balance sheet. This approach allows for easy comparison of financial performance across different companies or time periods, as it standardizes figures and highlights relative proportions rather than absolute values.
