Coverage, not leverage, is what kills your financing. The median borrower covers interest 1.6 times.

What is the difference, and why does it decide?

Leverage is a stock measure and coverage is a flow measure. Debt to EBITDA asks how large the loan is against a year of earnings. Interest coverage and fixed-charge coverage ask whether the cash the business produces actually pays what the business owes, this year, at today's rate. A lender sizes with the first and declines with the second.

The current prints show why. Median gross leverage across a portfolio of 2,785 middle-market borrowers and more than $1.2 trillion of debt held at 6.1x, unchanged on the quarter, while median interest coverage sat at 1.6x (KBRA, Q2 2026 Middle Market Compendium, for the twelve months ended 30 June 2026, published 28 July 2026). The leverage figure has barely moved for years. The coverage figure is the one that repriced when the base rate did.

This is also the mechanical answer to a question owners ask about their own covenant package. A debt-incurrence test typically permits new debt if either a leverage ratio or a fixed-charge coverage ratio is met. The leverage test is not sensitive to interest rates. The fixed-charge test is (Kricheff, A Pragmatist's Guide to Leveraged Finance). In a higher-for-longer environment, one of those two tests does all the binding.

What is the market actually clearing?

Less than it did a year ago, and the compression is worst at the small end. Senior debt for a borrower below $10m of EBITDA clears at 2.00x to 2.50x, with total debt at 2.50x to 3.25x, tightened during June 2026. The same borrower cleared 2.00x to 3.00x senior and 2.50x to 4.00x total in July 2025 (SPP Capital Partners, Market At A Glance, July 2026). Half a turn of senior capacity and three-quarters of a turn of total capacity left the market in a year.

Lenders describe the change in their own underwriting directly. Some 98% of surveyed private credit lenders report that standards became notably stricter since the start of 2026, the share expecting looser documentation fell from 33% to 4% over the year while the share expecting tighter documentation rose from 13% to 56%, and 55% would not provide payment-in-kind flexibility on a new buyout (Houlihan Lokey, Q2 2026 Private Credit Survey).

What clears at the small end, in practice, is conservative. A first-lien lower-middle-market lender reported new platform deals at 2.8x weighted-average senior leverage and 29% weighted-average loan to value for the quarter ended 30 June 2026 (Capital Southwest, Form 8-K). Another reported a lower-middle-market portfolio at median net senior debt to EBITDA of 2.5x and median EBITDA to senior interest of 3.0x, on an average portfolio company EBITDA of $11.2m (Main Street Capital, Form 8-K, as at 31 March 2026).

Where is the floor?

Around 1.0x on fixed-charge coverage, and lenders start acting well above it. Fixed charge coverage across a large middle-market sample sat at 1.3x in the first quarter of 2026, the third consecutive quarter at that level and up from a 1.1x trough in the first quarter of 2024, while the share of borrowers below 1.0x fell to 19.5% from a 40.9% peak in the second quarter of 2024 (Lincoln International, as at 31 March 2026).

Read that second number carefully. One borrower in five in that sample was not covering its fixed charges at all at the point of measurement, in a market that had improved for two years. The covenant floors lenders set, commonly in the 1.10x to 1.25x range on fixed-charge coverage, sit uncomfortably close to that.

The cushion around those floors is thinner than the headline suggests. A typical leverage covenant carries 25% to 35% headroom to the borrower's own model, and springing covenants trigger once revolver usage passes roughly 40% (Sidley Austin, 24 March 2026). A business that draws its revolver in a soft quarter can bring a covenant into existence at the precise moment it would rather not have one.

What does a lender do with your downside case?

Believes it, and underwrites to it. The base case is a negotiating document. The downside case is the model the credit committee prices, which is why a borrower who has not built one has effectively let the lender build it for them.

The historical lesson is about the calendar rather than the ratio. Coverage measured at closing tells you very little; what matters is whether the business services a known interest calendar in the quarters where earnings are weakest, because the coupon arrives on a schedule and the earnings do not (Bruner, Deals from Hell, on the Revco buyout, where a known coupon was missed nineteen months after closing).

There is a live cohort effect worth naming. Borrowers financed in the 2021 and 2022 vintages carry leverage around 0.9x higher than at underwriting and adjusted cash interest coverage around 0.4x lower, and refinancing risk for those vintages stays elevated through 2027 (VRC, Q2 2026). Rate expectations have stopped helping: the market read into 2027 is higher-for-longer, with no action more likely than cuts and potential increases beyond that (VRC, Q2 2026, July 2026). One agency does expect modest improvement in 2027, with median leverage declining slightly and EBITDA growth improving coverage, while noting that delayed rate relief will likely limit the pace of improvement (Fitch Ratings, 30 July 2026).

What can a borrower change before the term sheet?

The definition of EBITDA, first. Coverage is a ratio of two negotiated quantities, and the numerator is the one with more give in it. Adjustments and add-backs are where lenders and borrowers disagree most, and reported adjustments across the market are large enough that headline leverage and true leverage diverge materially. Reconciling the two before a lender does it is worth more than a spread concession.

Then the shape of the debt rather than its size. Amortization, cash interest against payment-in-kind, the size and pricing of the revolver, call protection, and whether the covenant is tested quarterly or springs on a drawn revolver all change the coverage profile without changing the leverage multiple. So does the equity contribution: lenders now require at least 40% base equity capitalization with at least 60% of it new cash, and independent sponsors are expected to show investment beyond rolled deal fees (SPP Capital Partners, July 2026).

Then the process. Run a limited approach to a handful of direct lenders and a bank for the revolver rather than negotiating against one relationship, because a second quote is the only thing that reliably holds pricing and leverage. And term out early where a maturity sits inside the window, since the opportunistic refinancing pipeline has largely exhausted itself and refinancing issuance fell 40.6% year on year in the first quarter of 2026 (PitchBook via Capstone Partners, Q1 2026).

None of that is exotic. It is the difference between arriving with a financing that has been underwritten and arriving with one that is about to be.
