Interest Coverage Ratio Calculator

Calculate a company's interest coverage ratio to assess debt repayment safety.

💵

Calculation Parameters

Specify your inputs below.

Calculated Result

Interest Coverage Ratio 3.00
💡

Expert Tip

A ratio below 1.5 indicates potential default risk, meaning operating profit barely covers debt service payments.

How this Calculator Works

This calculator computes the Interest Coverage Ratio, which measures how easily a company can pay interest on its outstanding debt. It compares operating profits (EBIT) against periodic interest expenses. Lenders and creditors use it to judge corporate solvency.

Formula & Methodology

Interest Coverage Ratio = EBIT / Interest Expense - EBIT is the Earnings Before Interest and Taxes. - Interest Expense is the total periodic interest cost on outstanding debt.

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

A company reports EBIT of $200,000 and has annual interest expenses of $40,000. 1. Divide EBIT by interest expense: $200,000 / $40,000 = 5.0. Result: The interest coverage ratio is 5.0.

FAQ

How does bond duration measure interest rate risk?
Modified duration estimates the approximate percentage change in a bond's price for a 1% (100 bps) shift in interest rates. Higher duration indicates greater price sensitivity to rate moves.
What is Tax-Equivalent Yield (TEY) for municipal bonds?
Tax-Equivalent Yield = Municipal Tax-Exempt Yield / (1 - Marginal Tax Rate). It shows the pre-tax yield a taxable bond would need to equal the after-tax yield of a tax-free municipal bond.
Can fixed income calculators guarantee bond trading outcomes?
No. Bond pricing models assume clean compounding yields and fixed reinvestment rates. Secondary market prices fluctuate based on liquidity, credit rating revisions, and market interest rate movements.
