There is another type of ratio analysis I often use which reports the percentage of items on the income statement. Below is an example of this type of ratio analysis.
I like this type analysis because it lets you see the contribution a particular item makes to your revenue, expenses, or income. For instance, you can see that taco sales are 41% of your total sales revenue. This may prompt you to expand the line of tacos you sell or you might place more emphasis on your burrito sales in order to diversify your revenue.
You may also use these ratios to make period to period comparisons. For example, you may ascertain that waste is the reason that is ground beef is 42% of your costs of sales. You may try preparing smaller portions of ground beef at a time in December in order to lower your ground beef costs. You can see if your efforts actually lowered the ground beef costs by comparing its percentage of the cost of sales on the December income statement.
