A revolver in finance is a revolving credit facility: a loan arrangement that lets a company borrow money up to a set limit, pay some or all of it back, and borrow again without having to renegotiate the deal. It works a lot like a corporate credit card. The credit line refreshes as the borrower pays it down, which is why companies rely on revolvers for day-to-day liquidity, seasonal cash needs, and emergencies.
How a Revolver Works
A revolving credit facility begins with a commitment from a lender, or from a group of banks acting together as a syndicate, to make a specific dollar amount available to the borrower. The borrower pulls funds in portions called drawdowns. Each drawdown reduces the remaining credit by that amount. Draw $25 million against a $100 million revolver and you have $75 million left to borrow.
The defining feature is what happens on repayment. Pay back some or all of what you borrowed, and that capacity returns to the line immediately. You can cycle through borrowing and repaying as many times as you need over the life of the facility. Most corporate revolvers run three to five years before maturity, at which point the company either refinances into a new facility or pays off whatever balance remains. During that window the total commitment stays fixed, and the borrower controls how much of it to use at any given moment.1Cornell Law School Legal Information Institute. Revolving Credit Facility
Revolver vs. Term Loan
The cleanest way to see what a revolver is involves comparing it with a term loan. A term loan is a one-time disbursement with a fixed repayment schedule. The borrower receives the money, pays it back in regular installments, and the available balance shrinks permanently with each payment. Once repaid, that portion of the loan is gone.
A revolver has no principal amortization at all. The company pays a fee to keep the line open, borrows when it needs cash, and repays when cash comes in. Most large corporate credit packages actually include both. The term loan provides a predictable chunk of long-term capital, often for an acquisition. The revolver handles the ongoing ups and downs of daily operations. The revolver is the checking-account buffer; the term loan is more like the mortgage.
What Companies Use Revolvers For
The most frequent use is smoothing out working capital gaps. A retailer buying inventory in September for the holiday season may not collect revenue from those sales until January. The revolver bridges that timing mismatch. The company draws to pay suppliers, then repays once customer payments arrive.
Revolvers also serve as a financial safety net. Many companies keep their revolver fully undrawn as a signal to investors, rating agencies, and counterparties that they have immediate access to liquidity if something goes wrong. An undrawn revolver on the balance sheet is essentially an insurance policy against cash flow disruptions.
Companies sometimes tap the revolver for smaller acquisitions or capital expenditures that don’t justify the time and expense of issuing bonds. The revolver lets them act quickly, then refinance into longer-term debt later if the amount is large enough to warrant it.
Most revolvers also carry built-in sublimits for specialized features. One is the letter of credit, a guarantee from the lender that it will pay a third party on the borrower’s behalf under agreed conditions, used routinely in international trade, real estate leases, and insurance. Another is the swingline loan, a small same-day borrowing feature for urgent cash needs that can’t wait the one to three business days a standard drawdown requires. Both reduce the overall available credit while they’re outstanding.
What a Revolver Costs
A revolver has two main costs: interest on what you borrow and a fee for having the rest available.
Interest applies only to the outstanding balance. The rate is almost always floating. Since the transition away from LIBOR, the standard benchmark for syndicated loans has been the Secured Overnight Financing Rate (SOFR), published daily by the Federal Reserve Bank of New York. The borrower pays SOFR plus a fixed margin, called the spread, that reflects the company’s credit risk. A healthy investment-grade company might pay SOFR plus 100 basis points. A riskier borrower could see SOFR plus 250 or more.2U.S. Securities and Exchange Commission. First Amendment to ABL Revolving Credit Agreement
The second cost is the commitment fee, charged on the undrawn portion of the facility. This compensates lenders for keeping capital reserved even when the borrower isn’t using it. Commitment fees typically run 0.25% to 0.50% per year, though they can climb higher for riskier credits. A $200 million revolver sitting completely undrawn at a 0.25% commitment fee costs the borrower $500,000 a year to maintain. That sounds like a lot until you consider what it buys: guaranteed access to $200 million on short notice.
Some facilities also carry smaller administrative fees, agent fees paid to the bank running the syndicate, and utilization fees that kick in when the borrower draws above a certain percentage of the total commitment.
Secured, Unsecured, and the Borrowing Base
In most corporate debt structures, the revolver is senior secured debt, meaning it has first or near-first claim on the company’s assets if things go badly. In leveraged finance deals, revolvers often hold a “super senior” position, ranking ahead of even the senior secured term loans and bonds. Banks insist on this priority because the revolver is a shorter-duration facility that needs to remain accessible in good times and recoverable in bad ones.
Unsecured revolvers also exist, but they’re reserved for the strongest borrowers, typically large investment-grade corporations whose financial strength alone satisfies lenders. The trade-off is predictable: unsecured facilities come with wider spreads and tighter covenants because the lender has no collateral to fall back on.
Not every revolver has a fixed amount you can draw against at any moment. In an asset-based lending (ABL) facility, the amount actually available fluctuates based on the value of the borrower’s collateral. The central concept is the borrowing base. The lender assigns advance rates to different categories of assets, and the sum determines how much credit is available. Accounts receivable, being the most liquid, typically carry the highest advance rates. Inventory advance rates depend on how quickly the goods can be sold, with finished products getting a higher rate than raw materials or work in progress.3Office of the Comptroller of the Currency.

The borrower submits a borrowing base certificate, usually weekly or monthly and sometimes daily, reporting the current value of eligible collateral. If receivables drop because a major customer paid slowly, the borrowing base shrinks, and the company may need to repay part of its outstanding balance even if no other term has been breached.
Covenants and What Happens If You Break One
Every revolver comes with covenants, contractual rules that restrict what the borrower can and cannot do while the facility is outstanding. Breaching a covenant triggers a technical default even if every interest payment is current.
Financial covenants require the borrower to maintain specific metrics. The most common is a leverage ratio cap, where total debt divided by earnings (usually EBITDA) must stay below an agreed ceiling such as 3.5 times. Another standard test is the interest coverage ratio, requiring that operating earnings exceed interest expense by some minimum multiple, often 2.0 to 3.0 times. A bad quarter that pushes the company past a threshold breaches the covenant regardless of whether the company can still make its payments.
Affirmative covenants are things the borrower must do: deliver audited financial statements on time, maintain adequate insurance, pay taxes, and comply with applicable laws. Missing a financial-statement filing deadline is one of the most common breaches in practice, and it’s entirely avoidable.
Negative covenants prohibit certain actions without lender consent. Selling a significant chunk of the company’s assets, taking on additional senior debt, or making large distributions to shareholders typically require approval from the lending group.
Many revolvers, especially in leveraged finance, also use springing covenants: financial tests that only activate when the company draws above a specified share of the facility, commonly 25% to 40%. If usage drops below that threshold on the next test date, the covenant goes dormant again. A company barely using its revolver doesn’t need the same scrutiny as one drawn heavily against it.
A covenant breach doesn’t automatically mean the lender seizes assets or demands immediate repayment, but it gives the lender the legal right to do so. The usual first step is a waiver or amendment: the borrower approaches the lending group, explains the situation, and asks for permission to operate outside the breached covenant temporarily. This almost always comes with a waiver fee and tighter terms going forward. Lenders may also impose new reporting requirements, demand additional collateral, or reduce the total commitment size.
If the breach is more serious or the lender has lost confidence, the parties may enter a forbearance agreement. The lender agrees not to exercise its acceleration rights for a defined period while the borrower works to fix the problem. In exchange, the borrower typically pays additional fees, accepts stricter covenants, and provides a detailed remediation plan. Forbearance is a temporary ceasefire, not a cure.
If negotiations fail, the lender can accelerate the loan, declaring the entire outstanding balance immediately due. For a company already under financial stress, forced acceleration of the revolver can cascade into broader default across the capital structure, because other debt agreements often contain cross-default provisions that trigger when one facility accelerates.
