Interest Coverage Ratio

Interest coverage ratio compares earnings available for interest with interest expense, commonly EBIT divided by interest expense.

What does interest coverage ratio mean?

Interest coverage ratio compares earnings available for interest with interest expense, commonly EBIT divided by interest expense.

In practical terms: Use it to assess debt-service capacity across consistent periods and definitions.

A practical example

Begin with a clearly defined reporting period and list the amounts or events included in the measure. Reconcile the result to the relevant cash-flow, income-statement or balance-sheet line before comparing it with another period or business.

How to analyze it

  1. Name the measure.
    State the exact definition and period.
  2. Trace the inputs.
    Identify the source statement, schedule or transaction for each figure.
  3. Reconcile the result.
    Check that subtotals connect to the appropriate statement or cash balance.
  4. Compare consistently.
    Use the same definition for every period or company in the comparison.

When should you use interest coverage ratio?

Use it to assess debt-service capacity across consistent periods and definitions.

Limitations and common mistakes

A zero or negative denominator or volatile earnings requires more than a simple multiple.

Do not mix annual figures with monthly figures, ending balances with averages, or percentages with whole numbers. Record the definition used so another person can reproduce the result.
