What is the Interest Coverage Ratio?
The interest coverage ratio measures the amount of earnings a business has available to make interest payments. It is calculated by dividing the earnings before interest and tax by the interest expense. It is sometimes called the interest cover ratio, times interest earned ratio, interest coverage or simply interest cover.
Formula for Interest Coverage Ratio
- Earnings before interest and tax (EBIT) is shown in the income statement. It is sometimes referred to as profit before interest and tax (PBIT).
- The interest expense is also found in the income statement and may be called interest or interest paid (interest received should be excluded from the calculation).
How to Calculate the Interest Cover Ratio
|Cost of sales||176,000|
|Earnings before interest and tax||64,000|
|Profit before tax||44,000|
|Profit after tax||35,000|
In the example above the earnings before interest and tax 64,000 and the interest expense is 20,000. The interest coverage ratio is given by using the formula Interest Coverage multiple = Earnings before interest and tax / Interest expense = 64,000 / 20,000 = 3.20.
Interest Coverage Ratio Interpretation
The interest cover ratio is a measure of the ability of a business to make interest payments on its debt, as such it is a measure of the credit worthiness of the business.
The business should aim to have a high interest coverage ratio which implies a profitable business with low debt. A high interest coverage will give a measure of security to the people who have lent the business money.
