Interest coverage

Measure how many times recurring earnings cover interest and reconcile the numerator, denominator and downside case.

Quick answer

Interest coverage measures the relationship between earnings and interest expense. A common form divides EBIT by interest expense; transaction documents may instead use EBITDA, fixed charges, cash interest or defined adjustments. The ratio must therefore be read with its exact definitions, period, permitted adjustments and covenant consequences.

Use the worked example

Meaning and transaction use

The IMF defines interest coverage as earnings divided by interest expense, using EBIT for earnings. It states that lower coverage indicates a heavier interest burden. [S1]

The IMF notes that coverage below 1 means earnings do not cover interest without measures such as cost reductions, cash use or further borrowing. Its 1.5 vulnerability discussion is an analytical example, not a universal covenant threshold. [S1]

Proposed control method: reconcile reported, adjusted and covenant-defined earnings; bridge cash, PIK, lease and hedge interest; and test rate, earnings and currency sensitivities.

Worked example

Illustrative coverage only. Assume EBIT of USD 4.5 million, cash interest of USD 2 million and PIK interest of USD 500,000.

Scroll the table horizontally to view all columns.

Measure	Calculation	Result
Cash interest coverage	4.5 / 2.0	2.25x
Total interest	2.0 + 0.5	USD 2.5 million
Total interest coverage	4.5 / 2.5	1.80x
Downside EBIT	4.5 x 80%	USD 3.6 million
Downside total coverage	3.6 / 2.5	1.44x

Coverage falls from 1.80x to 1.44x when EBIT declines by 20%. The applicable covenant result depends on the executed definition.

Proposed transaction review process

Select the definition

Identify EBIT, EBITDA or covenant earnings and the required interest measure.

Reconcile inputs

Bridge accounts to permitted adjustments, cash interest, PIK, leases and hedges.

Calculate headroom

Compare actual and forecast coverage with covenant or policy thresholds.

Stress

Test earnings, rates, currencies and refinancing assumptions.

Evidence checklist

Earnings evidence

Accounts, adjustments and forecast bridge.

Interest evidence

Facility schedules, cash payments, PIK accruals and hedge settlements.

Definition evidence

Executed agreement, certificate and amendment history.

Monitoring evidence

Forecast, sensitivities, compliance record and waivers.

Decision framework

Situation	Proposed action
PIK is excluded from cash coverage	Show cash and total interest coverage separately.
An add-back drives compliance	Verify its eligibility and cap under the agreement.
Headroom narrows	Update liquidity and remedial options before the test date.
Definitions differ across facilities	Calculate each facility separately and reconcile the group view.

Common errors to check

Using EBITDA when the agreement specifies EBIT.
Excluding PIK without stating it.
Mixing annual earnings with quarterly interest.
Applying a generic threshold as a contractual covenant.

Reconcile interest coverage

Bring the accounts, debt schedule, covenant definitions and forecast to an interest-coverage review. Quantify headroom under the documented base and downside cases.
