A pricing grid in a credit facility is a table built into your loan agreement that automatically raises or lowers the interest margin you pay based on a measurable trigger, usually a leverage ratio, a coverage ratio, or a credit rating. Each reporting period your financial numbers get plugged into the grid, the grid assigns you to a tier, and that tier sets your spread above the base rate until the next reset. The swing between the cheapest and most expensive tier is often 100 basis points or more, so the grid is one of the most consequential pieces of economics in the entire agreement.
How the Grid Changes Your Rate
Your all-in interest rate has two pieces: a base rate you don’t control and an applicable margin the lender charges on top. The grid only moves the margin. The base rate in nearly every U.S. dollar credit agreement is now the Secured Overnight Financing Rate (SOFR), which replaced LIBOR after LIBOR’s final cessation in 2023 and the end of synthetic LIBOR settings in September 2024.1Lexis Advance. Interest Rate Provisions in Credit Agreements SOFR If SOFR sits at roughly 3.65% and the grid puts you at a 1.50% applicable margin, you pay 5.15% on drawn balances.2Federal Reserve Bank of New York. Secured Overnight Financing Rate Data Improve your financial metrics and the grid walks the margin down. Let them slip and the margin walks up.
Most agreements apply a floor to the base rate so SOFR can’t drop below a stated minimum for interest calculation purposes. Investment-grade facilities often set the floor at 0.0%, which effectively means no floor unless rates go negative.3U.S. Securities and Exchange Commission. Amended and Restated Credit Agreement Leveraged facilities commonly set it at 0.50% or 0.75%. In a falling-rate environment, a floor caps how much relief you get from a declining benchmark.
What Triggers a Tier Change
The grid needs an objective number to decide which tier you fall into. In practice that number is one of three things.
Total Leverage Ratio
This is the most common trigger in leveraged credit facilities. It divides total funded debt by EBITDA. A borrower with $200 million of debt against $100 million of EBITDA runs at 2.0x and lands in a cheaper tier than one at 4.0x. The agreement’s definitions section spells out exactly what counts as debt (typically all funded obligations, letters of credit, and sometimes contingent liabilities) and which EBITDA add-backs are allowed (non-cash charges, one-time restructuring costs, and similar items).
Net Leverage Ratio
Some agreements use a net leverage ratio, subtracting unrestricted cash from total debt before dividing by EBITDA. This structure is more common in technology and software deals where borrowers hold large cash balances. A company with $300 million of debt and $100 million of cash shows 3.0x on a total basis but 2.0x net, which can mean a cheaper pricing tier.
Fixed Charge Coverage Ratio
Middle-market and asset-based facilities often use the fixed charge coverage ratio (FCCR) instead. The typical formula puts adjusted EBITDA minus capital expenditures minus cash taxes in the numerator, and cash interest expense plus required debt amortization in the denominator. Lease payments and preferred dividends sometimes join the denominator. A ratio below 1.0x means cash flow isn’t covering fixed obligations, which pushes the borrower into the most expensive tier or trips a covenant outright.
Credit Ratings
Investment-grade facilities usually peg the grid to corporate credit ratings from Moody’s, S&P Global, or both. An A3 or A- rating earns a lower margin than Baa2 or BBB, which in turn beats Baa3 or BBB-. A downgrade shifts you up the grid immediately or at the next reset. When the two agencies disagree, the agreement spells out the rule: use the lower, use the higher, or use the lower only when the split exceeds one notch.
What a Grid Looks Like
The grid is laid out as a table in a schedule or exhibit to the credit agreement. Each row is a tier defined by a range of the trigger metric. Each column shows what that tier costs. A simplified leverage-based grid typically looks like this:
- Tier 1, leverage below 1.50x: SOFR margin 1.25%, commitment fee 0.20%
- Tier 2, leverage 1.50x to 2.50x: SOFR margin 1.50%, commitment fee 0.25%
- Tier 3, leverage 2.50x to 3.50x: SOFR margin 1.75%, commitment fee 0.30%
- Tier 4, leverage 3.50x to 4.50x: SOFR margin 2.00%, commitment fee 0.35%
- Tier 5, leverage above 4.50x: SOFR margin 2.25%, commitment fee 0.40%
One basis point equals one-hundredth of one percent, so 125 basis points is 1.25%. On a $500 million facility, moving from Tier 1 to Tier 5 is a full percentage point of margin, which is $5 million per year of additional interest on fully drawn balances. That gap is the whole point of the structure.
Look at the second column. The commitment fee charged on the undrawn portion of a revolver moves in lockstep with the margin. Commitment fees generally run between 0.25% and 1.00%. Borrowers often overlook them during negotiations because the basis points look small, but on a large, lightly drawn revolver they add up. An undrawn $800 million of capacity on a billion-dollar revolver accrues commitment fees every day.
How and When Your Rate Resets
Grid adjustments don’t happen just because your financials changed. They’re triggered by a formal delivery, and the timing is where borrowers get hurt.
After each reporting period (quarterly for most facilities, annually for audited financials), a senior officer signs a compliance certificate that calculates the trigger ratios using the formulas defined in the agreement. The certificate pulls funded debt, letters of credit exposure, and EBITDA with contractual adjustments from the financial statements, confirms no events of default have occurred, and determines the tier for the next period. Officers signing the certificate are making a legal representation, so the calculations usually run through both accounting and legal review.
You deliver the certificate to the administrative agent, who verifies the math and notifies the syndicate. Most agreements make the new rate effective within three to five business days after delivery. If you miss the delivery deadline, nearly every credit agreement defaults your pricing to the highest tier on the grid until the certificate shows up. There is no grace period and no notice requirement. On a large facility, a two-week delay at the top tier can cost tens of thousands of dollars in excess interest. It’s one of the most common operational mistakes in loan administration and it’s entirely avoidable with a calendar system.
Once the new rate is set, it applies to all outstanding balances through the next reporting cycle. Then the process repeats.
How Asset-Based Facilities Price Differently
Asset-based lending (ABL) facilities use a different trigger entirely: how much borrowing capacity you have left. The more headroom in your borrowing base, the cheaper the rate. Tiers are defined by “excess availability” or “average revolving availability” as a percentage of the borrowing base or line cap. A filed agreement shows the pattern:4U.S. Securities and Exchange Commission. ABL Credit Agreement Exhibit 10.2.3
- Level I, availability at or above 66% of the line cap: SOFR margin 1.25%
- Level II, availability between 33% and 66%: SOFR margin 1.50%
- Level III, availability below 33%: SOFR margin 1.75%
The spread between best and worst tier is narrower than in a leveraged loan because the ABL lender has direct collateral. The same default-to-worst-tier rule applies: miss a borrowing base certificate deadline and the lender can price at Level III until it arrives.4U.S. Securities and Exchange Commission. ABL Credit Agreement Exhibit 10.2.3
ABL facilities also often include springing covenants that activate only when availability drops below a threshold. A borrower may have no financial maintenance covenants at all while availability stays above 15% of the borrowing base, but once it dips below that line a fixed charge coverage test springs into effect.5Office of the Comptroller of the Currency.

Add-On Features That Change the Grid’s Math
Most Favored Nation Protections
When a borrower raises incremental term debt under an existing credit agreement, existing lenders worry about being undercut if the new tranche prices higher. Most Favored Nation (MFN) provisions cap how much more expensive the new debt can be before the existing lenders’ rate gets bumped up to match. The typical U.S. threshold is 0.50%, with some sponsor-friendly deals pushing to 0.75%. If the new debt prices above that cushion, the existing term loans’ rate must increase to stay within the permitted gap.6U.S. Securities and Exchange Commission. Incremental Facility Amendment and Amendment No. 3 The adjustment can run through the margin itself or through an increase in the SOFR floor, which has the same economic effect when the floor is binding.
Sustainability-Linked Adjustments
A growing number of facilities layer an ESG-linked adjustment on top of the main grid. The adjustment usually runs plus or minus 2.5 to 15 basis points, with 7.5 the most common increment in recent deals. That’s deliberately small next to the 100-plus basis points a leverage grid can move. A two-way ratchet gives a discount for hitting a sustainability target and a penalty for missing it. A downward-only ratchet gives the discount but simply removes it when the target is missed, with no added penalty. Downward-only is more common, particularly in the mid-market, because it’s easier to negotiate. Targets vary: greenhouse gas emissions, renewable energy consumption, workplace safety incident rates, management-level diversity benchmarks. The sustainability report functions like a second compliance certificate, feeding the ESG overlay the way financial statements feed the primary grid.
Default Interest
The grid governs your rate during normal operations. A separate provision takes over when things go seriously wrong. Most credit agreements add a fixed premium, commonly 200 basis points, to whatever rate you’d otherwise pay once an event of default has occurred and is continuing. Some agreements set it higher, and the default rate typically applies to all outstanding obligations, not just overdue amounts. Default interest is distinct from the grid’s top tier. You can be at the most expensive grid tier and still get the additional default spread stacked on top. It usually accrues automatically once a default is declared, with no lender vote required.
