When headlines report that the Prime Rate stands at 6.75%, that number tells borrowers where pricing starts, not where it ends. The spread between the benchmark and the rate a borrower actually pays is the variable that determines real financing cost. A strong borrower with a bank term loan might pay 7.25%. A smaller SBA 7(a) borrower could face rates as high as 13.25%. Same rate environment, same headline number, vastly different outcomes. The spread is where the money is.
Key Takeaways
- Commercial loan pricing = benchmark + lender spread; the spread determines actual borrower cost
- Current Prime: 6.75%. Strong bank borrowers pay 7.25%-8.75%; smaller SBA borrowers face rates above 13%
- SBA 7(a) spreads capped by regulation: Prime + 3.00% (over $350K) to Prime + 6.50% (under $50K)
- 125 bps spread difference on a $500K loan adds ~$40,500 in interest over 10 years
- Benchmark rate cuts do not always reduce borrower costs; lenders may widen spreads in easing cycles
- FOMC meets March 18-19; rate hold widely expected

Benchmark Rates
Commercial loan pricing typically references one of a handful of benchmark rates. Each benchmark serves a different corner of the lending market.
| Benchmark | Current Rate | Common Use |
|---|---|---|
| Bank Prime Loan Rate | 6.75% | Most variable-rate business loans (SBA 7(a), term loans, lines of credit) |
| SOFR | 3.65% | Floating-rate commercial real estate, larger syndicated facilities |
| Federal Funds Target | 3.50%-3.75% | Sets the floor for Prime (Prime = upper bound + 3.00%) |
| 2-Year Treasury | 3.76% | Short-term fixed-rate loan pricing reference |
| 5-Year Treasury | 3.88% | Medium-term fixed-rate loan pricing reference |
| 10-Year Treasury | 4.27% | Long-term fixed-rate pricing (SBA 504, CRE permanent financing) |
What Is a Rate Spread?
The benchmark rate is the base. The spread is what the lender adds on top of it for risk, operating costs, and profit margin. When a lender quotes "Prime + 2.50%," the borrower pays the current Prime Rate (6.75% ) plus 2.50 percentage points, for a total rate of 9.25%. The spread reflects the lender's assessment of borrower creditworthiness, collateral quality, loan term, loan size, and industry risk. Two businesses applying for the same product on the same day can receive materially different spreads based on these factors. Borrowers who focus only on the benchmark miss the variable that actually determines their cost.
Key Statistic: In the current rate environment, the gap between the strongest and weakest commercial borrowers exceeds six percentage points, even when benchmark rates are identical.
What Borrowers Actually Pay
The table below maps the gap between benchmark rates and borrower-level pricing across major commercial lending products. SBA spreads are regulatory maximums set by the SBA; conventional ranges are market estimates.
| Product Type | Benchmark | Typical Spread | Resulting Rate Range |
|---|---|---|---|
| SBA 7(a) (over $350K) | Prime | + 3.00% max | Up to 9.75% |
| SBA 7(a) ($250K-$350K) | Prime | + 4.50% max | Up to 11.25% |
| SBA 7(a) ($50K-$250K) | Prime | + 6.00% max | Up to 12.75% |
| SBA 7(a) ($50K and under) | Prime | + 6.50% max | Up to 13.25% |
| Bank Term Loan (strong borrower) | Prime | + 0.50% to 2.00% | 7.25%-8.75% |
| Bank Term Loan (average borrower) | Prime | + 1.50% to 3.50% | 8.25%-10.25% |
| Business LOC (secured) | Prime | + 0.50% to 2.50% | 7.25%-9.25% |
| Business LOC (unsecured) | Prime | + 2.00% to 4.00% | 8.75%-10.75% |
| Equipment Financing | Various | Varies by equipment type and term | 5.50%-12.00% |
Benchmark vs. Spread by Product
Where Spreads Come From
Spreads are determined through three distinct mechanisms depending on the lending channel.
In government-guaranteed lending, the SBA sets maximum allowable spreads by loan size tier. Lenders compete within these caps. A borrower seeking an SBA 7(a) loan over $350,000 can expect that the rate will not exceed Prime + 3.00%, regardless of the lender. For loans between $50,001 and $250,000, the cap rises to Prime + 6.00%, reflecting the higher per-dollar cost of underwriting smaller credits.
In conventional bank lending, spreads are risk-based. The lender evaluates debt service coverage, collateral quality, industry risk, loan size, and the depth of the banking relationship. A firm with strong debt service coverage and solid collateral on a commercial term loan will typically negotiate a tighter spread than a newer business with limited operating history. These spreads are not published; they are calculated during underwriting.
Outside of benchmark-plus-spread pricing, online lenders and merchant cash advance providers often use factor rates or flat-fee models. Their pricing does not reference Prime or SOFR, which makes direct comparison more difficult. When evaluating these products, converting the total cost to an effective annual percentage rate provides the clearest basis for comparison.
Borrower Implications
How to Read a Rate Quote
When a lender quotes a rate, ask two questions: what benchmark does it reference, and what is the spread? A "9.50% rate" could mean Prime + 2.75% on a variable-rate loan, which will adjust with every Fed decision, or it could be a fixed rate priced off Treasury yields at origination. The structure matters as much as the number. Variable-rate borrowers inherit Fed policy risk; fixed-rate borrowers lock in their cost but give up the benefit of future cuts. Understanding the rate structure is the first step in evaluating any financing offer.
The Dollar Impact of Spreads
Small spread differences add up to significant dollar amounts over the life of a loan. Consider a $500,000 SBA 7(a) loan on a 10-year term. At Prime + 2.75% (9.50% total ), the monthly payment is approximately $6,470 and total interest over the life of the loan reaches approximately $276,400. At Prime + 1.50% (8.25% total ), the monthly payment drops to approximately $6,133 and total interest falls to approximately $235,900. That 125 basis point spread difference costs roughly $40,500 more in interest over the loan term, with the impact concentrated in the early years when the outstanding balance is highest. For firms evaluating multiple offers, running the numbers through a loan payment calculator can quantify the impact before signing.
What Drives a Tighter Spread
Lenders price spreads based on perceived risk. The factors that consistently produce tighter spreads include higher debt service coverage ratios, stronger collateral positions, larger loan amounts (which distribute fixed underwriting costs over more dollars), an established deposit or lending relationship with the institution, and operating in a lower-risk industry. Borrowers who can demonstrate strength across multiple dimensions have leverage to negotiate. Those with thinner profiles may find that business lines of credit offer a way to establish a track record before pursuing larger term facilities.
What to Watch
The FOMC meets March 18-19, with the decision released March 19 at 2:00 PM ET. A rate hold is widely expected, which would keep the federal funds target at 3.50%-3.75% and Prime at 6.75%. If the Fed holds, spreads remain the variable that differentiates borrower costs.
When the Fed eventually resumes cutting, Prime will drop the day after the decision. However, spreads do not automatically narrow. Lenders often widen spreads during easing cycles to protect margins, which can partially or fully offset the benchmark reduction. The Fed's Senior Loan Officer Opinion Survey (SLOOS) tracks whether banks are tightening or easing their spread requirements. The next SLOOS release (late April) and the May 6-7 FOMC meeting will provide the next data points on spread direction and benchmark rates, respectively.
