A revolving credit facility is a committed line of corporate credit that lets a borrower draw funds, repay them, and draw again up to a fixed ceiling over the life of the agreement. It is built for working capital: the day-to-day cash timing gaps caused by seasonal sales, inventory cycles, and the lag between money going out and money coming back in. The borrower pays interest only on what is actually drawn, plus a smaller fee on the undrawn capacity it is holding in reserve.
How the Draw-and-Repay Cycle Works
Reuse is the defining feature. On a traditional term loan, every dollar of principal you repay is gone for good. On a revolver, every dollar you repay becomes available to borrow again, and that cycle can repeat as many times as you need until the facility matures. The result is a pool of capital that expands and contracts with your actual cash needs, instead of sitting as a lump sum earning nothing or forcing you to pay interest on money you don’t need today.
Each draw starts with a borrowing notice sent 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. 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. You pay interest only on what is outstanding, and you can pay the balance down the moment surplus cash arrives. That ability to size borrowings precisely to the day’s needs is why a revolver is the standard tool for operational liquidity rather than long-term capital investment.
What You Can Actually Borrow
Two numbers anchor every revolving credit facility: the commitment amount and the maturity date. The commitment is the absolute ceiling you can access. It stays fixed unless the parties formally agree to change it. Corporate revolvers typically carry maturities of three to five years, consistent with their working capital purpose. Lenders may allow extensions, but renewal requires a fresh credit review before the original term expires.
Committed versus uncommitted is a distinction worth understanding before you sign. 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 keeps discretion to decline a funding request even if you technically qualify. Most corporate RCFs are committed, and the commitment fee you pay is the price of that guaranteed access. If you are counting on a credit line for operational liquidity, confirm you have a committed facility, because an uncommitted line offers no certainty when cash is tight.
The Borrowing Base
Many facilities, particularly asset-based ones, cap availability not just at the commitment but at a borrowing base tied to the value of your most liquid collateral. Lenders apply an advance rate to categories of eligible assets to determine what you can actually draw. 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, often monthly. If receivables age past their eligibility window or inventory values decline, the base shrinks and your available credit drops automatically. If your outstanding balance now exceeds the reduced base, you face a mandatory paydown. Growth in eligible assets expands what you can draw without renegotiating the agreement. Pay close attention to how “eligible” is defined, because assets subject to prior liens, aged receivables, consignment inventory, or foreign receivables may be excluded, and the narrower the eligibility criteria, the smaller the effective base relative to your total asset sheet.
Conditions Precedent
Every draw must satisfy conditions precedent. Your representations and warranties must remain accurate as of the draw date, no default can be outstanding, and the requested amount cannot push the balance past the borrowing base or commitment. These conditions give the lender a fresh credit check at every drawdown without requiring new underwriting.
Collateral and the Security Interest
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, commonly called 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 is at the front of the line.
The typical 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 you can pledge elsewhere. Negative covenants usually prohibit additional liens on the same assets without lender consent, keeping the collateral pool from being diluted.
What It Costs
The all-in cost of a revolver has more parts than just the interest rate. Several fee layers compensate lenders for reserving capital and administering the facility, and the commitment fee in particular is often larger than borrowers expect.
Interest on Drawn Amounts
Interest is calculated as 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
Because daily SOFR fluctuates and borrowers prefer rate certainty for a defined period, most agreements 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 you submit a drawdown notice, you select an interest period, and the applicable Term SOFR rate for that tenor is locked in for the duration. At the end of the period, you can roll into a new one at the then-current rate, repay the balance, or convert to a different tenor.
The credit spread on top of SOFR reflects your risk profile, leverage, and market conditions at the time of 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 your leverage ratio changes, rewarding deleveraging and penalizing deterioration. Some facilities also carry a small SOFR adjustment, typically a few basis points, introduced during the transition from LIBOR to account for the structural difference between the two rates.
Fees Beyond Interest
- Commitment fee, charged on the average daily unused portion of the commitment. If you have a $100 million facility and draw $40 million on average, the fee applies to the remaining $60 million. Rates typically range from 15 to 50 basis points depending on credit quality and leverage.
- Utilization fee, imposed by some agreements when outstanding draws exceed a specified percentage of the commitment, often 50 percent. It discourages heavy usage that concentrates lender exposure and 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. These are negotiated as a percentage of the total commitment and are not recurring.
- Administrative agent fee, an annual flat charge paid to the bank serving as administrative agent for managing day-to-day operations, payment flows, and compliance monitoring.
- Letter of credit fees, charged on outstanding LC exposure when the facility includes an LC subfacility. The fee is usually equal to the applicable credit spread, plus a smaller fronting fee to the issuing bank.
When modeling the true cost of a revolver, 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 cost is the price of certainty, and it is the reason uncommitted facilities, which carry no commitment fee, exist as a cheaper but less reliable alternative.
Subfacilities Inside the Revolver
Letters of Credit
Most revolvers include a letter of credit subfacility. An LC 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 your available revolving credit dollar for dollar, even though no cash has been drawn. If you have a $50 million commitment and $10 million in outstanding LCs, your remaining availability for cash draws is $40 million, subject to borrowing base limits.
Swingline
A swingline is a smaller subfacility that lets you access funds the same day, bypassing the standard one-to-three-day notice period. 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 feature exists for urgent, short-term cash needs where the standard notice period would be too slow. The sublimit is always a fraction of the total commitment.
The Rules You Have to Follow
Covenants are the behavioral guardrails of the credit agreement. They protect the lenders’ investment by restricting your 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 you must take. The most important is the timely delivery of financial statements: audited annual financials, unaudited quarterly reports, and compliance certificates confirming all covenants are met. Other requirements include maintaining adequate insurance, paying taxes, and preserving the legal existence of the borrowing entities. These obligations are rarely contentious, 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 you can do without lender consent. The most consequential include limits on additional debt, restrictions on asset sales outside the ordinary course, caps on dividends and share repurchases, prohibitions on additional liens, and limits on investments and acquisitions. Each restriction typically includes negotiated exceptions, called baskets, that give you room to operate. The size and flexibility of those baskets is where much of the negotiation energy goes.
Maintenance Covenants
Maintenance covenants are financial performance tests that lenders check on a recurring basis, usually quarterly. The two most common are a maximum leverage ratio, meaning total debt divided by EBITDA, and a minimum debt service coverage ratio, meaning net operating income divided by total debt service payments. A DSCR of 1.25x, for example, means the business must generate $1.25 of operating income for every $1.00 of debt payments. Falling below the required threshold is a 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. Understand exactly what counts before signing.
Springing Covenants
In many leveraged facilities, the financial maintenance covenant does not 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, while the banks holding revolving commitments insisted on retaining at least one financial test.
What Counts as a Default
A covenant breach is the most common trigger, but credit agreements define a broader set of events as default. The consequences are severe: lenders can stop funding new draws, accelerate the entire outstanding balance (demanding immediate full repayment), and enforce their security interest against the collateral.
- Payment default. Failing to make an interest or fee payment when due. Most agreements include a short grace period, often two to five business days, before a missed payment becomes an event of default.
- Covenant default. Breaching a financial maintenance test or violating a negative covenant. Financial 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 RCF, even if the revolver itself is current. This prevents selective default on other creditors while keeping the revolver in good standing.
- 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. A severe and sudden decline could still give lenders the right to stop funding and accelerate, even without a specific covenant breach.
- Change of control. An acquisition, a change in majority ownership, or a turnover of the board beyond specified thresholds. Lenders underwrote based on existing ownership and management; if new parties take over, they want the ability to reassess.
- 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. Acceleration converts the revolving facility into a demand obligation, and if the borrower cannot pay, the lenders can move to foreclose on the collateral. In practice, most defaults lead to negotiation rather than immediate enforcement, because lenders prefer a workout or amendment that preserves value over a fire sale.
Growing the Facility: Accordion Features
Many credit agreements include an accordion provision, sometimes called an incremental facility, that lets the borrower increase the total commitment without negotiating an entirely new deal. You can request additional revolving commitments or term loans, provided you satisfy 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 that you 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. Existing lenders are not obligated to participate, so you may need to bring in new banks to fill the incremental capacity.
The feature is valuable because it lets a growing business scale upward at a lower transaction cost than a full refinancing. The trade-off is that the conditions 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 incremental capacity.
Tax Treatment of Revolver Costs
Two federal tax rules matter most: the deductibility of commitment fees and the cap on business interest deductions.
The IRS has treated commitment fees paid on an unused revolver as currently deductible ordinary business expenses in certain circumstances. Published IRS guidance has concluded that quarterly commitment fees calculated on the average daily unused balance of a revolving commitment are deductible in the year paid, rather than capitalized and amortized over the facility’s term. The distinction is between fees that function as a recurring cost of maintaining access to a credit line and fees that function as a cost of acquiring a loan. If a commitment fee resembles a standby charge for the right to borrow, more like an option premium, capitalization may be required instead.
Separately, Section 163(j) of the Internal Revenue Code limits the total business interest a company can deduct in a tax year to the sum of its business interest income plus 30 percent of its adjusted taxable income.5Office of the Law Revision Counsel. 26 USC 163 – Interest Disallowed interest carries forward to future years. Small businesses that meet a gross receipts test (average annual gross receipts of $30 million or less, adjusted for inflation) are exempt. For larger borrowers, the 163(j) limitation means the tax benefit of revolver interest is not unlimited, and the effective after-tax cost of the facility depends on how much total interest expense the company is already carrying across all its debt.
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 the two 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, typically quarterly. The revolver has no required amortization; principal repayment is voluntary until the maturity date, 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 is drawn and a commitment fee on what is undrawn, which makes it far cheaper to hold as standby liquidity.
Most borrowers need both. The term loan provides certainty of long-term funding, while the revolver provides the flexibility to manage cash timing mismatches without parking unnecessarily large cash reserves on the balance sheet. Shared collateral and a shared covenant framework simplify documentation and align the interests of all lenders under a single intercreditor arrangement.
