Prime Rate and Revolving Credit Facilities: What Corporate Borrowers Need to Know

Fact-checked by the Prime Rate editorial team

The revolving credit facility prime rate is not a fixed cost. It is a moving floor that resets whenever the Federal Reserve adjusts the federal funds rate, and every drawn dollar on a corporate revolver pays the price. The Wall Street Journal reports the U.S. prime rate at 6.75%, posted by at least 70% of the country’s ten largest banks, including JPMorgan Chase and Bank of America. That figure has held steady since December 11, 2025, following a series of Federal Reserve rate cuts from the 8.5% peak that defined 2023.

For corporate treasury teams, that stability offers a brief window to model borrowing costs with unusual confidence. Whether to lock in terms now or wait for further Federal Open Market Committee action is a real decision with real dollar consequences.

What Exactly Is a Revolving Credit Facility?

A revolving credit facility (RCF) is a committed bank line that lets a borrower draw, repay, and re-draw up to an agreed limit without taking out a new loan each time. Unlike a term loan, there is no fixed amortization schedule. The borrower controls the timing and size of each drawdown, which is precisely why RCFs are the workhorse instrument for corporate working capital and short-term liquidity management.

Mid-to-large corporate revolvers typically range from $50 million to several billion dollars, with tenors of three to five years. Investment-grade borrowers, including large publicly rated corporations, use them primarily as liquidity backstops; many facilities go mostly undrawn for long stretches. According to the Federal Reserve Bank of Boston’s 2026 research, unused revolving lines of credit represent roughly 20% of bank liabilities, a signal of just how much committed-but-undrawn capacity sits on bank balance sheets at any given moment.

The mechanics differ meaningfully from personal lines of credit. Corporate RCFs typically include financial covenants (minimum interest coverage ratios, maximum leverage tests), borrowing base provisions for asset-backed structures, and multi-lender syndications overseen by an administrative agent, often a major institution such as JPMorgan Chase, Wells Fargo, or Citibank. Borrowers gain large committed capacity at competitive pricing, but they accept ongoing reporting obligations and covenant compliance as part of the deal. That is a genuine trade-off, not a footnote.

How Does the Prime Rate Directly Affect RCF Borrowing Costs?

Most corporate revolvers price drawn balances at prime plus a margin, and at 6.75% prime today, the all-in drawn rate for an investment-grade borrower runs approximately 7.25–8.125%. That margin, typically 0.5–1.375% for investment-grade facilities and up to 2% or higher for leveraged borrowers, is usually set on a grid tied to the company’s credit rating or leverage ratio. A stronger balance sheet earns a lower margin; a rating downgrade from agencies such as Moody’s or S&P Global Ratings can trigger an automatic step-up.

Prime vs. SOFR: The Hybrid Reality

The shift toward Secured Overnight Financing Rate (SOFR) pricing accelerated after LIBOR’s retirement in 2023, but many 2025–2026 credit agreements still retain a prime or base-rate option alongside Term SOFR published by the CME Group. Borrowers who draw under the base-rate option (typically prime or the fed funds rate plus a spread) pay a known, published rate rather than working through SOFR’s compounding mechanics. For short-duration draws or smaller borrowers, prime-based pricing remains the simpler choice.

The practical implication is real money. Consider a $100 million revolver with $40 million drawn. At prime plus 1% (that is, 7.75%), the monthly interest expense on the drawn balance is approximately $258,333 ($40M × 7.75% ÷ 12). A 25-basis-point Federal Reserve rate increase, moving prime to 7.00%, would add roughly $8,333 per month, or about $100,000 per year, on that same drawn amount. Those incremental costs compound quickly if the Fed reverses course. The broader effects of a rising prime rate ripple across virtually every variable-rate product, revolving facilities included.

Beyond Interest: Fees, Covenants, and Costs That Rarely Make the Headline

What does a revolving credit facility cost when you never draw on it? More than most borrowers budget for. Commitment fees, charged on the undrawn portion of the facility, run 0.25–0.50% per year for most corporate revolvers. On a $100 million facility with only 30% utilization, the company still owes fees on the remaining $70 million in undrawn capacity. At 0.35% annually, that is $245,000 per year in fees on money it has not touched.

Upfront arrangement fees and annual agency fees add to the stack. A large syndicated revolver may carry a one-time arrangement fee of 0.25–0.75% of the facility size, paid at close. Those costs amortize over the tenor, but they affect the true annual percentage rate (APR) calculation and should be included in any comparison against alternative liquidity sources such as commercial paper programs or FDIC-insured deposit facilities. For business owners who track borrowing costs the same way they track personal debt reduction strategies, the discipline is the same: know your true all-in cost before committing.

Covenants and Springing Maturity Risks

Financial covenants are not boilerplate. A typical maintenance covenant might require the borrower to maintain a net leverage ratio below 4.0x or a fixed-charge coverage ratio above 1.25x, tested quarterly. A covenant breach does not automatically trigger default, but it gives lenders the right to accelerate the facility, which is effectively the same outcome if the borrower cannot cure or obtain a waiver quickly.

Springing maturity provisions add another layer: if a large tranche of the borrower’s other debt matures before the revolver, the revolver’s maturity can spring forward to 91 days before that debt, compressing the timeline without any formal default. These provisions appear in roughly half of leveraged facility structures, yet they rarely surface in rate comparisons or CFPB-style cost disclosures. Borrowers who skip the covenant schedule when reviewing term sheets often discover these risks only when it is too late to renegotiate.

Negotiating and Managing Your Prime-Linked Revolver in 2026

Strong credit metrics give borrowers more room in negotiations than they typically use. Most lenders offer margin grids that step the spread up or down as the borrower’s leverage ratio moves. A company that improves from 3.0x to 2.0x net leverage could see its margin drop by 25–50 basis points automatically, without renegotiating the agreement. Borrowers who understand their grid can plan capital allocation to hit the lower tier before a scheduled re-pricing period.

Two negotiation features worth asking about: accordion provisions and sustainability-linked margin adjustments. An accordion allows the borrower to increase the committed facility size without a full restructuring, useful if growth capital needs arise unexpectedly. Sustainability-linked pricing, now common in European facilities arranged by banks such as BNP Paribas and HSBC, and growing in U.S. agreements, ties the margin to ESG performance metrics and offers a modest spread reduction of 2–5 basis points for hitting targets.

For business owners whose personal finances are intertwined with their company, the floating rate on a corporate revolver can create indirect pressure on household cash flow. A sustained prime rate increase affects both corporate borrowing costs and, in many cases, personal credit products tied to the same benchmark. Understanding how the prime rate affects credit card interest rates gives owners a fuller picture of their combined rate exposure. Personal credit scores, tracked through bureaus such as Experian, Equifax, and TransUnion and summarized in a FICO Score, become directly relevant if a small-business owner must provide a personal guarantee on a smaller facility. In those cases, the quality of a borrower’s personal credit score has direct implications for corporate facility pricing.

Rate risk management deserves a direct answer: hedging via interest rate swaps can convert floating prime-based draws into fixed-rate exposure, but the swap itself carries a cost and counterparty credit risk. Borrowers who expect prime to fall further from 6.75% may prefer to stay unhedged for now, though that is a directional bet, not a strategy. Lenders including SoFi and regional banks increasingly offer hybrid structures with partial fixed-rate components, which can reduce exposure without a standalone derivative. The same rate dynamics that affect home equity lines apply to corporate revolvers: variable-rate borrowers benefit when rates fall and pay the price when they rise.

Frequently Asked Questions

What is the prime rate for revolving credit facilities right now?

The U.S. prime rate is 6.75%, posted by at least 70% of the ten largest U.S. banks. It has been unchanged since December 11, 2025, following a series of Federal Reserve rate cuts from the 8.5% peak reached in mid-2023.

Is a revolving credit facility better than a term loan for corporate borrowers?

Each instrument serves a different purpose. A revolving credit facility is better for working capital, seasonal cash flow, and liquidity backstops, situations where the borrower needs flexible, repeatable access rather than a one-time disbursement. Term loans are better for fixed capital expenditures or acquisitions where the repayment schedule can be planned in advance. Many borrowers carry both simultaneously.

How is interest calculated on a prime-based revolving credit facility?

Interest accrues only on drawn balances, calculated as the current prime rate plus the agreed margin, applied to the outstanding principal on a daily or monthly basis. A $40 million draw at prime-plus-1% (7.75% today) generates approximately $258,333 in monthly interest. Undrawn capacity is not interest-bearing but does carry a separate commitment fee.

Do corporate revolvers still use the prime rate, or have they all switched to SOFR?

Many have switched to SOFR, but prime-based pricing has not disappeared. Across 2025–2026, a significant share of credit agreements retain a base-rate option (typically prime or fed funds plus a spread) alongside Term SOFR, giving borrowers a choice at each drawdown. Smaller borrowers and mid-market lenders still frequently offer prime-only pricing.

What commitment fee should I expect on an undrawn revolver?

Investment-grade borrowers typically see commitment fees of 0.25–0.35% per year on undrawn balances; leveraged borrowers may pay up to 0.50%. On a $100 million facility with 70% undrawn, a 0.35% commitment fee costs $245,000 annually, a real carrying cost even when the line is used purely as a liquidity buffer.

Can a business owner’s personal credit affect corporate revolver pricing?

Yes, for smaller facilities or those requiring a personal guarantee. Lenders evaluating a sub-$10 million revolver for a closely held company often review the owner’s personal credit profile, including their FICO Score and debt-to-income (DTI) ratio, as part of underwriting. A stronger personal credit score can support a lower margin or reduce the need for restrictive covenants. Larger, rated corporate facilities generally do not carry this dependency.
