The prime rate is the benchmark most business credit is priced against, and nearly all variable-rate business lines and cards are quoted as prime plus a margin — so when prime moves, your rate moves with it. As of mid-2026 the U.S. prime rate sits in the low-to-mid single digits above the federal funds rate, and the average interest a small business actually pays lands well above prime once the lender's margin, your credit profile, and the product type are stacked on top. A strong-credit business line might price near prime plus 1-3 points; a business credit card commonly runs prime plus 10-15 points; and short-term or revenue-based funding is not quoted in APR at all — it uses a factor rate on cash flow. This guide breaks down what each product really costs, why "the prime rate" alone never tells you your price, and when chasing a low posted rate costs you more than taking faster capital.
Key takeaways
- The prime rate tracks the Federal Reserve's federal funds target, historically running about 3 points above it, and reprices variable business credit within days of a Fed move.
- Almost no small business borrows at prime — you're quoted prime plus a margin set by your credit, time in business, industry, and collateral.
- Business credit cards commonly price around prime plus 10-16 points; strong-credit secured lines can run as low as prime plus 1-3.
- Revenue-based and MCA marketplace funding are not tied to prime at all — they use a factor rate on your revenue, so cost doesn't move with the Fed.
- Revenue-based funding approves on bank deposits and revenue over credit score, with FICO 500+, amounts from about $10,000, and funding in 24-48 hours.
- Moving your personal FICO or crossing two years in business changes your margin more than a one-point shift in prime does.
- Fast approval reflects strong, consistent deposits and is never guaranteed.
What the prime rate is and how it sets your business credit price
The prime rate is the interest rate U.S. banks publish for their most creditworthy commercial borrowers. It is not set by the government directly — it moves in lockstep with the Federal Reserve's federal funds target, historically running about 3 percentage points above it. When the Fed raises or cuts, prime follows within days, and every variable-rate product tied to it reprices at the next cycle.
Almost no small business borrows at prime. Instead, lenders quote prime + a margin based on your risk. That margin is where your real cost lives:
- Prime is the floor the market gives the safest borrowers.
- The margin is what the lender adds for your credit score, time in business, industry, and collateral.
- The product multiplies it further — an unsecured card carries a far larger margin than a secured line.
So two businesses can borrow "at prime plus" and pay wildly different rates. The prime rate is the tide; your margin is the boat you're in.
Average interest by product type (what businesses actually pay)
"Average business credit interest" is a misleading phrase because the range is enormous across products. Below are representative bands for how each common product is priced relative to prime. Treat these as directional; your quote depends on your file.
| Product | Typical pricing basis | How it's expressed | Where average cost lands |
|---|---|---|---|
| Bank business line of credit | Prime + 1 to 6 pts | Variable APR | Low if strong credit; reprices with the Fed |
| Business credit card | Prime + 10 to 16 pts | Variable APR | High; only cheap if paid in full monthly |
| SBA 7(a) loan | Prime + capped spread | Variable APR | Moderate; slow to fund |
| Conventional term loan | Fixed or prime-indexed | Fixed/variable APR | Moderate; underwriting-heavy |
| Online term loan | Risk-priced | APR (often high) | Higher; faster than bank |
| Revenue-based / MCA funding | Not prime-linked | Factor rate on revenue | Priced on cash flow, not FICO; fastest |
The critical takeaway: bank products move with prime, but revenue-based funding is decoupled from the prime rate entirely. When the Fed hikes and bank lines get more expensive and harder to draw, factor-rate funding on deposits doesn't reprice against a benchmark — it's underwritten on the cash your business is already generating.
Why your credit score and revenue change the number more than prime does
Owners fixate on the prime rate because it's in the news, but for most small businesses the margin swamps the benchmark. A one-point move in prime changes your line's rate by one point. Moving from a 620 to a 720 personal FICO, or from 12 to 36 months in business, can swing a lender's margin by several points — and can be the difference between an approval and a decline.
Lenders build your margin from a short list of inputs:
- Personal FICO of the owner(s) — the single biggest driver on unsecured products.
- Time in business — under two years pushes you out of most bank pricing.
- Revenue consistency — steady monthly deposits lower perceived risk.
- Industry — some sectors carry blanket surcharges or exclusions.
- Collateral — secured lines price far tighter than unsecured.
This is exactly why a business with real revenue but a thin or bruised credit file often can't touch the low prime-plus rates the calculators show — the low number exists, but not for that borrower. See our guide to business loan interest rates for how these inputs combine into a final quote.
Fixed vs. variable: what prime exposure means for your payments
Prime-indexed credit is variable by design. When you sign a prime-plus line, you're accepting that your rate — and your minimum payment — rises every time the Fed hikes. In a rising-rate stretch, businesses that leaned on variable lines watched their carrying cost climb quarter after quarter without borrowing another dollar.
The tradeoffs:
- Variable (prime-indexed): lower starting rate, full exposure to Fed moves, unpredictable payment. Good when rates are flat or falling.
- Fixed: higher starting rate, complete payment certainty, no benchmark risk. Good when you need to budget precisely or expect hikes.
- Factor-rate (revenue-based): cost is set at funding and doesn't move with prime at all; repayment flexes with your daily or weekly revenue instead.
If predictability of cash flow matters more than shaving the headline rate, a cost that's fixed at the outset — whether a fixed loan or a factor-rate advance — removes the benchmark-risk that variable prime-plus credit carries.
Decision framework: rate-shopping vs. taking revenue-based funding
The prime rate matters when you qualify for prime-linked credit and have time to wait for it. It stops mattering when the constraint is speed, credit profile, or approval odds. Use this to decide which lane you're in.
Chase the lowest prime-plus rate when:
- Owner FICO is roughly 680+ and the business has 2+ years of history.
- You have clean financials and can wait weeks for bank or SBA underwriting.
- The need is planned (equipment, expansion), not an emergency.
- You'll carry the balance long enough that rate compounds into real money.
Prioritize revenue-based / MCA marketplace funding when:
- FICO is 500+ but not bank-grade, and you need approval on bank deposits and revenue over credit.
- You need $10,000 or more and can't wait weeks — funding in 24-48 hours solves the actual problem.
- The capital is tied to a fast return: inventory before a season, a job that needs materials now, covering payroll through a receivables gap.
- A bank already declined you, or your time in business is under two years.
Avoid revenue-based funding when: the need isn't time-sensitive, you comfortably qualify for prime-plus bank credit, or the use of funds won't generate cash quickly enough to service repayment from revenue. Matching the tool to the situation beats optimizing a single number. Note: fast approval is never guaranteed — it reflects strong, consistent deposits.
A realistic example: same business, three funding paths
Consider, for example, a specialty contractor with roughly $60,000 in monthly deposits, 18 months in business, and a 610 owner FICO who needs about $40,000 to buy materials for a signed job starting in ten days. Here's how the paths compare — not on total-dollar cost, but on fit.
| Path | Likely outcome | Speed | Fit for this job |
|---|---|---|---|
| Bank line (prime + margin) | Likely declined — under 2 yrs, sub-680 FICO | Weeks | Poor: misses the start date |
| SBA 7(a) | Possible but paperwork-heavy | Weeks to months | Poor: far too slow |
| Revenue-based marketplace | Approvable on deposits, FICO 500+ | 24-48 hours | Strong: funds before the job starts, repays from the revenue the job produces |
The prime-linked options may carry a lower posted rate, but a lower rate on capital you can't get in time is worth nothing. The revenue-based path is priced on the cash flow the business already shows and repays as that cash flow comes in — the cost is the price of moving now, and the job's margin covers it.
How to lower your real cost of business credit
Whether you're borrowing against prime or on a factor rate, the levers that lower your cost are mostly about your file, not the benchmark:
- Strengthen the owner's personal credit — it compresses the margin on every prime-plus product.
- Keep deposits clean and consistent — no negative days, minimal NSFs; this is what revenue-based underwriters read first.
- Separate business and personal banking — clean statements underwrite faster and cheaper.
- Borrow to a return, not to a gap — capital tied to revenue-producing use is the easiest to service and the safest to take.
- Match term to purpose — short needs to short funding, long assets to long financing; mismatches are where cost quietly balloons.
- Right-size the draw — take what the job needs, not the maximum offered.

Frequently asked questions
What is the current prime rate and how often does it change?
The prime rate is a benchmark set by banks that tracks the Federal Reserve's federal funds target, historically about 3 points above it. It changes only when the Fed changes rates — so it can hold steady for months and then move within days of a Fed decision. Any variable business credit tied to prime reprices at the next billing cycle after a move.
Why is my business credit rate so much higher than the prime rate?
Because you're almost never quoted prime itself — you're quoted prime plus a margin. That margin is added for your credit profile, time in business, industry, and the product type. An unsecured business credit card commonly runs prime plus 10-16 points, while a strong-credit secured line might run prime plus just 1-3. The benchmark is the same; the margin is where your real cost is decided.
Is a business credit card or a line of credit cheaper?
A business line of credit almost always carries a lower rate than a business credit card, because the card's unsecured, revolving nature commands a much larger margin over prime. A card is only cost-competitive if you pay the balance in full every month and never carry it. For balances held over time, a line or term product is typically far cheaper.
Does revenue-based funding use the prime rate?
No. Revenue-based funding and merchant cash advance marketplace products are priced with a factor rate on your revenue, not as prime plus a margin. That means the cost is set at funding and doesn't move when the Fed hikes or cuts. Approval is based on your bank deposits and revenue rather than your credit score, which is why businesses that can't reach prime-plus bank pricing often use it.
What credit score do I need for the lowest prime-plus business rates?
The tightest prime-plus pricing generally goes to owners with personal FICO around 680 and up, plus two or more years in business and clean financials. Below that, bank margins widen sharply or applications are declined. Revenue-based funding is the common alternative, with approvals on FICO 500 and up when deposits and revenue are strong and consistent.
Should I choose a fixed or a variable (prime-indexed) business rate?
Choose variable prime-indexed credit when you want the lowest starting rate and expect rates to stay flat or fall — but accept that your payment rises with every Fed hike. Choose fixed pricing when you need payment certainty to budget or expect rates to climb. Factor-rate revenue-based funding is a third option where cost is fixed at funding and repayment flexes with your revenue.
How fast can I get business funding compared to a prime-rate bank line?
Bank lines and SBA loans priced against prime typically take weeks, and SBA can take months. Revenue-based marketplace funding is built for speed and can fund in 24-48 hours on amounts starting around $10,000. Fast turnaround reflects strong, consistent deposits and is never guaranteed, but it's the practical choice when timing is the real constraint.
Is chasing the lowest rate always the right move?
No. A low prime-plus rate is worth nothing if you can't qualify for it or can't get the money in time. When the need is urgent, your credit is below bank grade, or the capital is tied to a fast return, revenue-based funding priced on cash flow often beats a lower posted rate you'd wait weeks for. Match the product to the situation rather than optimizing a single number.
