After getting head wise costs of the company, you need to compare each expenses to the revenue to know what percentage of the revenue has been spent towards these expenses.

To convert the number into a percentage, you need to divide each expenses of income statement by total revenue and multiple it by 100.

For instance, it cost of goods sold and revenue of a company is 65 and 100 respectively, then to you can calculate the percentage by dividing 65 by 100 and multiply it with 100 ((65/100)*100), which comes to 65%. This measures that company’s COGS is 65% of the revenue. If due to certain economic factors, costs are going up and revenue is down, then it will have a impact on the company’s bottom line.
