Interest Coverage Ratio Formula
The interest coverage ratio is a ratio that measures the ability of a company to pay interest on its debt on time. It does just calculate the ability of a company to make payment of interest, not principle. The investor uses this to calculate a risk associated with a company and also to help to understand the profitability of a company. An investor also checks whether a company can pay its due on time without affecting its business and profitability. Borrowing can be shortterm or longterm.
The interest coverage ratio represents a margin of safety. The interest coverage ratio formula can be written as in reference to EBIT, EBITDA. There are two types of formula. Let’s discuss the same.
 Interest Coverage Ratio Formula using EBIT
The interest coverage ratio formula is EBIT for the period upon total interest payable in the given period. EBIT is earnings before interest and tax. The formula for same can be written as:
 Interest Coverage Ratio Formula using EBITDA
Here, noncash income is also added to EBIT. A formula for the same can be written as EBIT for the period plus noncash expenses divided by total interest payable in the given period. Here, EBITDA is Earnings before interest, tax, depreciation, and amortization. An Interest Coverage Ratio formula can be written as:
This Interest Coverage Ratio Formula can be written as:
Examples of Interest Coverage Ratio Formula
Let’s take an example to understand the calculation of Interest Coverage Ratio in a better manner.
Interest Coverage Ratio Formula – Example #1
Suppose, a company R&R Pvt. Ltd has EBIT $100,000 for 2018, and the total interest payable for 2018 is $40,000.
Solution:
Now, let’s calculate the interest coverage ratio using EBIT.
 Interest Coverage Ratio = EBIT for the Period / Total Interest Payable in the given Period
 Interest Coverage Ratio = 100,000 / 40,000
 Interest Coverage Ratio = 2.5
Interest coverage ratio for R&R Pvt. Ltd. is 2.5
Interest Coverage Ratio Formula – Example #2
A consulting company has below the financial statement for the years 2017 and 2018. A company is new in the market and growing. Company has total revenue of $165,000 in 2018, $150,000 in 2017 and expense of $25,300 in year 2018, $18,450 expense in year 2017. Through this and considering other income and other expense earning before tax and income are calculated which help to find profit before tax and profit after tax and finally one can get an interest coverage ratio.
Solution:
Assuming an income tax of 10%.
Particulars  2018  2017 
Revenue:  
Advisory Fees  $ 75,000.00  $ 90,000.00 
Consultancy Fees  $ 90,000.00  $ 60,000.00 
Total Revenue(A)  $ 165,000.00  $ 150,000.00 
Expenses:  
Direct Expense  $ 14,500.00  $ 12,000.00 
Advertisement Expense  $ 3,000.00  $ 2,000.00 
Commission Paid  $ 500.00  $ 300.00

Depreciation  $ 7,000.00  $ 4,000.00 
Total Operating Expense(B)  $ 25,300.00  $ 18,450.00 
Operating Income(AB)  $ 139,700.00  $ 131,550.00 
Other Income  $ 8,000.00  $ 7,000.00 
Other Expense  $ 700.00  $ 500.00 
Earning before tax and income  $ 147,000.00  $ 138,050.00 
Interest  $ 9,000.00  $ 7,000.00 
Profit Before Tax  $ 138,000.00  $ 131,050.00 
Tax (10%)  $ 13,800.00  $ 13,105.00 
Profit after Tax  $ 124,200.00  $ 117,945.00 
Now, let’s calculate interest coverage ratio using EBIT for 2017.
 Interest Coverage Ratio = EBIT for the Period / Total Interest Payable in the given Period
 Interest Coverage Ratio for 2017 = 138,050 / 7000
 Interest Coverage Ratio for 2017 = 19.72
Now, let’s calculate interest coverage ratio using EBIT for 2018.
 Interest Coverage Ratio = EBIT for the Period / Total Interest Payable in the given Period
 Interest Coverage Ratio for 2018 = 147,000 / 9000
 Interest Coverage Ratio for 2018 = 16.33
Interest Coverage Ratio Formula – Example #3
Suppose, a company ADC Pvt. Ltd has EBIT $100,000 for year 2018, noncash expense is $4,000 and total interest payable for 2018 is $40,000.
Now, let’s calculate the interest coverage ratio using EBITDA.
Interest Coverage Ratio = (EBIT for the period + Noncash Expense) / Total Interest Payable in the given period
 Interest Coverage Ratio = (100,000 + 4000) / 40,000
 Interest Coverage Ratio =104,000 / 40,000
 Interest Coverage Ratio = 2.6
Interest coverage ratio for ADC Pvt. Ltd. is 2.6
Interest Coverage Ratio Formula – Example #4
A company has below financial statement for the year 2018. Through this let’s calculate Interest coverage ratio. The company is applicable for 10% Tax.
Particulars  2018 
Revenue:  
Advisory Fees  $ 100,000.00 
Consultancy Fees  $ 92,630.00 
Total Revenue(A)  $ 192,630.00 
Expenses:  
Direct Expense  $ 74,000.00 
Advertisement Expense  $ 5,000.00 
Commission Paid  $ 700.00 
Miscellaneous Expense  $ 500.00 
Depreciation  $ 6,000.00 
Total Operating Expense(B)  $ 86,200.00 
Operating Income(AB)  $ 106,430.00 
Other Income  $ 5,000.00 
Other Expense  $ 1,000.00 
Earning before tax and income  $ 110,430.00 
Interest  $ 10,000.00 
Profit Before Tax  $ 100,430.00 
Tax (10%)  $ 10,043.00 
Profit after Tax  $ 90,387.00 
Now, let’s calculate interest coverage ratio using EBITDA.
 Interest Coverage Ratio = (EBIT for the period + Noncash Expense) / Total Interest Payable in the given period
 Interest coverage ratio = (110,430 + 6,000) / 10,000
 Interest coverage ratio = 116,430 / 10,000
 Interest Coverage Ratio = 11.64

Now, let us analyze the interest coverage ratio. The interest coverage ratio is calculated to understand the risk associated with a company it also helps the financial institution to check the repayment capacity of a company. It is basically used to check solvency. Let’s see interest coverage ratio values and their meaning they are as follow:
 If a company has an interest coverage ratio less than 1 that means a company is risky and not in a condition to pay neither the interest nor principle against its debt. Financial institutions never give them loans as there is a high chance that loans can become NPA i.e. nonperforming assets.
Interest Coverage Ratio < 1
 If a company has an interest coverage ratio equal to 1 that means a company is quite risky, it is able to pay just interest amount to the lender, not principle. These types of a company also never get any loan from the financial institution as there is a risk involved of principle.
Interest Coverage Ratio = 1
 If a company has an interest coverage ratio greater than 1 that means a company has money to pay interest against its debt and also an extra amount to pay against the principal.
Interest Coverage Ratio > 1
 Ideally, the interest coverage ratio should be greater than 1.5, in this scenario a financial institution will give a loan easily. A risk associated with a company will also be low as a company will have a sufficient amount to repay interest and principal to a lender.
Interest Coverage Ratio >= 1.5
 If the interest coverage ratio goes below 1.5 then, it is a red alert for a company and with this risk associated with a company will also increase.
Interest Coverage Ratio < 1.5
