Fixed Charge Coverage Ratio Calculator

What this calculator does

Interest is not the only bill a company cannot skip. Rent falls due whether or not trade was good. Equipment leases are contracts, not preferences. This calculator measures whether operating profit covers those unavoidable commitments alongside the interest:

Fixed charge coverage = (EBIT + Lease payments) ÷ (Interest expense + Lease payments)

It exists because the simpler interest coverage ratio has a specific and rather serious blind spot, one that gets larger the more a company rents rather than owns. Before the worked example shows what that blind spot costs, the formula itself needs explaining, because the way lease payments appear twice looks like a mistake.

Why lease payments appear on both sides of the fraction

Adding the same figure to the top and the bottom of a fraction seems like it should cancel out. It does not, and the reason is worth following because it is the whole logic of the ratio.

Start with the denominator, which is the easy half. You are asking whether earnings cover the fixed commitments, so the commitments have to be listed: interest plus lease payments. That is the bill.

Now the numerator. EBIT has already had the lease payments taken out of it, because rent is an operating expense deducted before you arrive at operating profit. So if you used EBIT as it stands, you would be asking whether earnings that have already paid the rent are sufficient to pay the rent again. Adding the lease payments back restores the profit figure to what the business earned before committing to any of these fixed charges. That is the right pool of money to measure the bill against.

So the two appearances do different jobs: the numerator undoes a deduction, and the denominator states an obligation. And they do not cancel, because the numerator and denominator start from different sizes. Adding the same amount to both moves the ratio toward 1, which is exactly right: as a larger share of a company's fixed costs sits in leases rather than interest, its coverage should look less like the flattering interest-only figure and more like the tight reality.

The three figures it needs

1. EBIT. Operating profit before interest and tax, as reported, with lease and rent costs still deducted. The calculator adds them back for you, so do not adjust EBIT yourself or you will double-count.
2. Interest expense. The finance charge for the period.
3. Lease payments. The rent and lease charges for the same period. Enter 0 if the company leases nothing, in which case the result will simply equal the interest coverage ratio.

Press Calculate for the multiple, or Reset to clear the fields. In practice, lenders often define fixed charges more broadly than leases alone, adding scheduled debt repayments, insurance, or other non-cancellable commitments. This tool uses the common textbook version built on leases, so if you are checking a loan covenant, read its definition first, because the contract's wording rather than the standard formula is what will bind you.

The same business, bought against rented

This comparison is the reason the ratio exists. Take two companies with genuinely identical economics. Each generates 18,000,000 of profit before paying for its premises and its financing. They differ only in one decision.

Company A buys its premises, funded with debt. It has no rent, so its EBIT is the full 18,000,000, and it pays 6,000,000 of interest.

• Interest coverage: 18,000,000 ÷ 6,000,000 = 3.00
• Fixed charge coverage: (18,000,000 + 0) ÷ (6,000,000 + 0) = 3.00

Company B rents its premises for 6,000,000 a year and carries almost no debt, paying just 500,000 of interest. Because the rent is an operating expense, its EBIT is 18,000,000 minus 6,000,000, which is 12,000,000.

• Interest coverage: 12,000,000 ÷ 500,000 = 24.00
• Fixed charge coverage: (12,000,000 + 6,000,000) ÷ (500,000 + 6,000,000) = 2.77

Look at what interest coverage claims. Company B scores 24 against Company A's 3, which would suggest it is eight times safer. That is nonsense. Both companies must find 6,000,000 a year for their premises. One calls it interest and the other calls it rent, and only one of those words appears in the interest coverage ratio.

The fixed charge ratio sees through it. At 2.77 against 3.00, the two businesses come out roughly where they should: similar commitments, similar cover, with A marginally ahead. The point is not that renting is bad. It is that a company can look dramatically safer on interest coverage purely by shifting its fixed costs from a form the ratio counts into a form it ignores, and this ratio closes that gap.

What lenders do with this number

Fixed charge coverage is used less as an analytical curiosity than as a condition of borrowing. It appears routinely in loan agreements as a covenant, a promise the borrower makes to keep the ratio above an agreed floor, tested each quarter or year. Fall below it and the lender gains rights, which can range from higher pricing to demanding immediate repayment.

The floors are usually set with meaningful headroom. Above 2 is broadly regarded as healthy, and covenant minimums are frequently set at or near that level so a single poor quarter does not trigger a breach. A ratio of 1 means the company earns precisely enough to meet its fixed charges and nothing more, and below 1 it is not covering them from operations at all.

Which is worth remembering when reading any company that leases heavily. Retailers, airlines, restaurant chains and logistics businesses can have modest borrowings and enormous lease commitments, so their interest coverage can look serene while a very large annual cash obligation sits outside it entirely. For those businesses this is the more truthful of the two ratios, and it is the one their lenders will be watching.

Questions people ask

How is this different from interest coverage?

Interest coverage counts only interest. This adds lease payments to the obligations and adds them back to earnings, so it measures cover for fixed commitments as a whole. For a company with no leases the two are identical.

Should I add lease payments back to EBIT myself?

No. Enter EBIT as reported, with rent already deducted, and let the calculator add it back. Adjusting it yourself would count the leases twice and overstate the coverage.

What is a good fixed charge coverage ratio?

Above 2 is generally considered healthy and is a common covenant floor. A ratio of 1 means earnings exactly meet fixed charges with nothing spare, and below 1 they do not cover them.

Do fixed charges include anything besides leases?

They can. Lenders often include scheduled principal repayments and other non-cancellable commitments in their own definitions. This calculator uses the common leases-based version, so check the wording of any covenant you are testing against.

References

The fixed charge coverage ratio measures whether earnings cover contractual obligations that must be paid regardless of trading, extending the interest coverage ratio to take in lease payments and, in lender-defined versions, mandatory debt repayments and other non-cancellable charges. Lease payments are added back to earnings because they have already been deducted in arriving at operating profit, restoring the earnings available before those fixed charges, and then set out as an obligation in the denominator.
