Revolving Credit Facility

A revolving credit facility is a committed bank credit line that permits a company to borrow, repay, and reborrow funds repeatedly up to a negotiated maximum amount. The borrower pays interest only on the amount drawn, not on the unused commitment, making it a flexible tool for managing seasonal cash flows and operational contingencies.

Why companies depend on revolving facilities

A revolving credit facility differs fundamentally from term loan debt: money borrowed is returned and available again to borrow. This reset mechanism makes revolvvers ideal for companies with uneven cash needs. A retailer facing seasonal demand peaks, a manufacturer managing input-cost volatility, or a service firm bridging gap timing between customer invoicing and payment all benefit from the flexibility to access cash when needed and reduce the outstanding balance when cash is abundant.

Most mid-market companies maintain a revolving credit facility as insurance against liquidity squalls. Unlike commercial paper or other short-term market financing, a committed revolver is a legal contract with a specific lender—the bank cannot cancel the facility on a whim, which provides certainty. The company pays an upfront commitment fee (typically 0.25–0.75% of the undrawn amount) and interest on whatever is actually borrowed.

Mechanics: draw, repay, and redraw

Imagine a manufacturing company has a $50 million revolving facility. In January, facing strong demand, it draws $30 million to buy raw materials. As it sells finished goods, cash comes in; by March it repays $15 million. The facility resets—it now has $35 million available again, and can redraw that $15 million if needed. This cycle repeats over the facility’s life, typically three to five years.

The mechanics are governed by a detailed credit agreement. The company and its banks establish conditions for drawing (minimum draw sizes, notice periods), prepayment terms (often free, to encourage early repayment), and reporting obligations (monthly financials, covenant calculations). The company also agrees to maintain certain financial metrics—a maximum debt-to-equity ratio, minimum interest coverage, or floor on working capital—that protect the lender if the company weakens.

Interest rates on revolvvers are pegged to a reference rate (typically SOFR) plus a spread of 1.5–3.0% depending on creditworthiness. Investment-grade companies pay tighter spreads; weaker credits pay wider spreads to compensate banks for risk.

The commitment fee and unutilized portion

One counterintuitive feature: the company pays a fee even on money it does not borrow. This commitment fee (often called an “undrawn fee”) typically runs 35–50% of the margin spread, applied to the undrawn portion. If a $50 million facility has a 2% margin and 35% of the margin applies to undrawn funds, the company pays roughly $350,000 annually in commitment fees even if it draws nothing.

This structure aligns incentives: the bank is compensated for keeping capital on standby; the company avoids paying full interest on capital it may not use. For companies with volatile or uncertain cash flows, this arrangement is far cheaper than maintaining excess cash reserves or funding all working capital through short-term market debt.

Revolvers as liquidity backups

In practice, a revolving facility often sits underutilized but indispensable. A company with strong operating cash flow might keep the facility nearly untouched; it serves as a safety net. In a cash-flow crunch—a lost customer, a delayed receivable, a one-time investment—the company can draw instantly without negotiating new debt. This psychological and legal safety valve is worth the commitment fee alone.

During economic stress, the true value of a revolver becomes apparent. Companies with solid facilities can weather short-term setbacks; those without face forced asset sales or covenant breaches. Banks, anticipating this dynamic, scrutinize revolver sizing closely. Too small, and the facility offers no real cushion; too large, and it represents excess debt capacity the company does not need.

Revolver syndication and agent banks

Larger revolving facilities are typically syndicated: multiple banks participate, each committing a portion of the total facility. One bank acts as the administrative agent, managing the credit agreement, collecting payments, and calculating covenants. The agent bank typically earns a fee (often $50,000–500,000, depending on facility size) for this work.

Syndication spreads risk across lenders and allows the arranger to place the facility with a diverse investor base. A $200 million revolver might be split among ten or twelve banks, each taking a $15–20 million slice. This distribution makes it easier for any single bank to exit (by selling its portion) and reduces concentration risk.

Subordination and availability

Revolving facilities sit atop the capital structure. They are senior to preferred stock and common stock, but typically junior to secured debt backed by specific assets (real estate, equipment). In a bankruptcy, revolver holders would recover before shareholders but after secured creditors.

Availability can shrink if the company violates covenants. A typical revolver includes a “springing” basket lender—if leverage exceeds a threshold, the company must reduce its borrowing availability until leverage improves. This mechanic incentivizes covenant compliance and limits the damage if a company begins to deteriorate.

Compare to term debt and longer-term financing

A revolving facility is distinct from term loans, which require scheduled amortization (fixed principal reductions over time). A term loan is permanent debt with a defined payoff schedule; a revolver is optionally tapped. For large capital expenditures—a plant expansion, an acquisition—companies typically use term loans or bonds. For day-to-day working capital, revolvvers are the norm.

Some firms layer both: a $50 million revolver for operations and a $200 million term loan to fund a factory. The term loan amortizes predictably; the revolver handles lumpy, short-term needs.
