A revolving credit facility is a committed line of credit that lets a corporate borrower draw, repay, and redraw funds up to a set maximum over a fixed contractual period, paying interest on what’s drawn and a fee on what isn’t. It’s the standard tool for working capital: bridging the gaps between when cash goes out for payroll, inventory, and suppliers and when it comes back in from customers. The structure has a lot of moving parts, but they all serve one purpose, which is giving a business a pool of capital that expands and contracts with actual need instead of sitting as a lump sum.
How Drawing and Repaying Works
The defining feature is reuse. On a traditional term loan, repaid principal is gone. On a revolver, every dollar of principal you repay becomes immediately available to borrow again, and that cycle can repeat as many times as you need until the facility matures.
To pull funds, the borrower submits a borrowing notice to the administrative agent specifying the amount and the interest period. Most agreements require one to three business days of advance notice for a standard draw. Same-day access is sometimes available through a swingline subfacility, covered below. Agreements also impose a minimum draw amount so the lending group isn’t processing trivially small transactions.
Repayments on the revolving portion are voluntary and penalty-free at any time. Interest accrues only on the balance actually outstanding, and the borrower can pay down as soon as surplus cash arrives. That ability to size borrowings precisely to the day’s needs is what makes the revolver an operational tool rather than a capital-investment one.
How Much You Can Actually Borrow
Two numbers anchor availability. The first is the commitment amount, which is the absolute ceiling. It stays fixed unless the parties formally agree to change it. Corporate revolvers typically carry maturities of three to five years, reflecting their working-capital purpose, and any extension requires a fresh credit review before the original term expires.
The second number, in many facilities, is the borrowing base. Asset-based revolvers cap availability at a formula tied to the borrower’s most liquid collateral. Lenders apply an advance rate to categories of eligible assets to determine what can actually be drawn. The Office of the Comptroller of the Currency notes that banks typically advance 70 to 80 percent against eligible accounts receivable and 20 to 65 percent against eligible inventory, with lower rates warranted when the collateral carries heightened risk.1OCC. Accounts Receivable and Inventory Financing
The borrowing base is recalculated regularly, sometimes monthly. If receivables age past their eligibility window or inventory values decline, the base shrinks and the available credit drops automatically. If the outstanding balance exceeds the newly reduced base, the borrower faces a mandatory paydown. Growth in eligible assets works the same way in reverse and expands what can be drawn without renegotiating the agreement.
Eligibility definitions matter as much as advance rates. Assets subject to prior liens, receivables past a certain age, inventory held on consignment, or foreign receivables may be excluded. The narrower the eligibility criteria, the smaller the effective borrowing base relative to the borrower’s total asset sheet.
Committed vs. Uncommitted Facilities
This is the distinction to confirm before signing anything. Under a committed revolver, the lenders are contractually obligated to fund any draw that satisfies the agreement’s conditions. Under an uncommitted facility, the lender retains discretion to decline a funding request even if the borrower technically qualifies.
Most corporate RCFs are committed, and the commitment fee is the price of that guaranteed access. A borrower relying on a credit line for operational liquidity should verify it has a committed facility, because an uncommitted line offers no certainty when cash is tight, which is precisely when you need it.
Even under a committed facility, every draw must satisfy conditions precedent. Representations and warranties must remain accurate as of the draw date, no existing default can be outstanding, and the requested amount cannot push the total balance past the borrowing base or commitment amount. Those conditions give the lender a fresh credit check at every drawdown.
Collateral and Security
Nearly all corporate revolvers are secured. The borrower grants the lenders a security interest in its assets, and the lender group perfects that interest by filing a financing statement (a UCC-1) under Article 9 of the Uniform Commercial Code.2Legal Information Institute. UCC Article 9 – Secured Transactions Perfection establishes priority: if the borrower defaults and other creditors come calling, the perfected secured party stands first in line.
The typical collateral package is a blanket lien covering substantially all of the borrower’s assets: receivables, inventory, equipment, intellectual property, deposit accounts, and general intangibles. The breadth of that lien gives lenders broad protection and also limits what the borrower can pledge elsewhere. Negative covenants normally prohibit granting additional liens on the same assets without lender consent.
How Interest Is Priced
Interest on a drawn revolver is a benchmark reference rate plus a credit spread. Since the phase-out of LIBOR, the standard benchmark for U.S. dollar credit facilities is the Secured Overnight Financing Rate, or SOFR. The New York Federal Reserve calculates SOFR daily as the volume-weighted median cost of borrowing cash overnight using Treasury securities as collateral.3Federal Reserve Bank of New York. Secured Overnight Financing Rate Data
Raw daily SOFR fluctuates, and borrowers prefer rate certainty for a defined interest period. Most loan agreements therefore use Term SOFR, a forward-looking rate published by CME Group for one-month, three-month, six-month, and twelve-month tenors.4CME Group. Term SOFR When the borrower submits a drawdown notice, it picks an interest period, and the applicable Term SOFR rate for that tenor is locked in for the duration. At the end of the period, the balance can roll into a new period at the then-current rate, be repaid, or convert to a different tenor.
The credit spread on top of SOFR reflects the borrower’s risk profile, leverage, and market conditions at negotiation. Investment-grade borrowers pay tighter spreads; leveraged borrowers pay wider ones. Many agreements include a pricing grid that adjusts the spread up or down as the borrower’s leverage ratio changes, rewarding deleveraging and penalizing deterioration. Some facilities also carry a small SOFR adjustment of a few basis points, introduced during the LIBOR transition to account for the structural difference between the two rates.
Fees Beyond Interest
The all-in cost of a revolver goes well beyond the interest on drawn funds. Several fee layers compensate lenders for reserving capital and administering the facility.
- Commitment fee. Charged on the average daily unused portion of the commitment. On a $100 million facility with $40 million drawn on average, the commitment fee applies to the remaining $60 million. Rates typically range from 15 to 50 basis points depending on credit quality and leverage.
- Utilization fee. Some agreements impose an additional charge when outstanding draws exceed a specified percentage of the commitment, often 50 percent. This can add 10 to 25 basis points on top of the interest rate when triggered.
- Arrangement and upfront fees. One-time charges paid at closing to the arranging banks for structuring and syndicating the facility, negotiated as a percentage of the total commitment.
- Administrative agent fee. An annual flat fee paid to the bank serving as administrative agent for managing day-to-day operations, payment flows, and compliance monitoring.
- Letter of credit fees. If the facility includes an LC subfacility, the borrower pays a fee on outstanding LC exposure, usually equal to the applicable credit spread, plus a smaller fronting fee to the issuing bank.
The commitment fee matters more than most borrowers initially expect. A company that maintains a large undrawn facility for liquidity insurance pays a meaningful annual cost for capital it never touches. That’s the price of certainty, and it’s the reason uncommitted facilities exist as a cheaper but less reliable alternative.
Letters of Credit and Swinglines
Most revolvers include two subfacilities that change how availability and timing actually work.
A letter of credit is a guarantee from the issuing bank that it will pay a third party, such as a supplier or landlord, if the borrower fails to do so. The face amount of every outstanding LC reduces the borrower’s available revolving credit dollar for dollar, even though no cash has been drawn. With a $50 million commitment and $10 million in outstanding LCs, remaining availability for cash draws is $40 million, subject to any borrowing base limit.
A swingline is a smaller subfacility that allows same-day access to funds, bypassing the standard one-to-three-day notice for regular draws. Swingline loans are typically funded solely by the swingline lender, usually the administrative agent, and are then settled among the broader syndicate within a few business days. The swingline sublimit is always a fraction of the total commitment, and the feature exists for urgent short-term cash needs where the standard notice period would be too slow.
Covenants and Financial Tests
Covenants are the behavioral guardrails of the credit agreement. They protect the lenders’ investment by restricting the borrower’s ability to take on excessive risk or dilute the collateral. A breach of any covenant typically constitutes an event of default, giving lenders the right to accelerate the debt.
Affirmative Covenants
These are actions the borrower must take. The most important is timely delivery of financial statements: audited annual financials, unaudited quarterly reports, and compliance certificates confirming all covenants are met. Other common requirements include maintaining insurance, paying taxes, and preserving the legal existence of the borrowing entities. These are rarely contentious in negotiation, but missing a reporting deadline can trigger a technical default that gives lenders leverage even when the business is performing well.
Negative Covenants
Negative covenants restrict what the borrower can do without lender consent: limits on additional debt, restrictions on asset sales outside the ordinary course of business, caps on dividends and share repurchases, prohibitions on additional liens, and limits on investments and acquisitions. Each restriction typically includes negotiated exceptions called “baskets.” The size and flexibility of those baskets is where much of the negotiating energy in a credit agreement goes.
Maintenance Covenants
Maintenance covenants are the financial performance tests lenders check on a recurring basis, usually quarterly. The two most common are a maximum leverage ratio (total debt divided by EBITDA) and a minimum debt service coverage ratio (net operating income divided by total debt service payments). A DSCR of 1.25x means the business must generate $1.25 of operating income for every $1.00 of debt payments. Falling below the required threshold is a covenant breach even if every payment has been made on time.
The definition of EBITDA in a credit agreement is almost never the textbook version. Negotiated “add-backs” for restructuring charges, non-cash expenses, and one-time costs can inflate the number materially. Borrowers want expansive add-backs to create covenant headroom; lenders want tight definitions to keep the test meaningful. This is one of the most heavily negotiated provisions in any credit agreement.
Springing Covenants
In many leveraged facilities, the financial maintenance covenant doesn’t apply all the time. It “springs” into effect only when revolver usage exceeds a specified threshold, commonly 35 to 40 percent of the total commitment. If utilization drops below the trigger on the next test date, the covenant goes dormant again. The structure emerged because term loan lenders in the broadly syndicated market accepted covenant-lite terms, but the banks holding revolving commitments insisted on retaining at least one financial test. A springing covenant is the compromise.
Events of Default
A covenant breach is the most common trigger, but credit agreements define a broader set of events that constitute a default. The consequences are severe: lenders can stop funding new draws, accelerate the entire outstanding balance to demand immediate full repayment, and enforce their security interest against the collateral.
- Payment default. Failing to make an interest payment or fee payment when due. Most agreements include a short grace period, often two to five business days, before a payment default ripens into an event of default.
- Covenant default. Breaching a financial maintenance test or violating a negative covenant. Financial covenant breaches may have a cure period; negative covenant violations typically do not.
- Cross-default. A default on another debt obligation above a specified dollar threshold triggers a default under the revolver, even if the borrower is current on the revolver itself.
- Material adverse change. A significant deterioration in the borrower’s business, financial condition, or prospects. MAC clauses are powerful but vague, and lenders invoke them cautiously because proving a MAC in court is difficult.
- Change of control. An acquisition, a change in majority ownership, or a turnover of the board beyond specified thresholds. Lenders underwrote the facility based on existing ownership and management, and this trigger gives them the ability to reassess if that changes.
- Bankruptcy. A voluntary or involuntary bankruptcy filing is an immediate event of default with no cure period.
When a default is declared, the administrative agent acts on behalf of the syndicate. The lenders vote, usually by a majority of commitments, on whether to accelerate, waive, or amend the terms. In practice, most defaults lead to negotiation rather than immediate enforcement. Lenders prefer a workout or amendment that preserves value over a fire sale of assets.
Accordion and Incremental Capacity
Many credit agreements include an accordion provision, also called an incremental facility, that lets the borrower increase the total commitment without negotiating an entirely new deal. The borrower can request additional revolving commitments or term loans, provided it satisfies conditions written into the original agreement, such as maintaining a specified leverage ratio on a pro forma basis after giving effect to the increase.
The accordion typically has two components. The first is a fixed dollar basket the borrower can access without a leverage test. The second is an uncapped or loosely capped amount available so long as pro forma leverage stays below a specified threshold. Only the administrative agent and the lenders actually providing the new commitments need to consent; the broader syndicate has no veto. Existing lenders are not obligated to participate, so the borrower may need to bring in new banks to fill the incremental capacity.
The feature lets a growing business scale its facility upward at a lower transaction cost than a full refinancing. The trade-off is that the conditions for exercise are written at the time of the original agreement, so a borrower whose credit profile has deteriorated since closing may not be able to satisfy the leverage test when it actually needs the extra room.
Revolver vs. Term Loan
The most common corporate financing structure pairs a revolving credit facility with a term loan under the same credit agreement, so it helps to see where they diverge.
- Repayment and reuse. A term loan is drawn once, and every principal payment permanently reduces the balance. The revolver allows indefinite reuse of repaid principal until maturity.
- Amortization. Term loans require scheduled principal payments, usually quarterly. The revolver has no required amortization; principal repayment is voluntary until maturity, when any remaining balance comes due in full.
- Purpose. Term loans finance specific, one-time needs: acquisitions, equipment purchases, refinancings. The revolver funds the ongoing ebb and flow of working capital and provides a liquidity backstop.
- Cost when idle. A term loan charges interest on the full outstanding balance from day one. A revolver charges interest only on what’s drawn and a commitment fee on what’s undrawn, making it far cheaper to hold as standby liquidity.
Most borrowers need both. The term loan provides certainty of long-term funding; the revolver provides the flexibility to manage cash timing mismatches without maintaining unnecessarily large cash reserves. The two facilities share the same collateral package and covenant framework, which simplifies documentation and aligns the interests of all lenders under a single intercreditor arrangement.
