Best low-interest business loans in 2026
The lowest-interest business loans are SBA 504 loans for real estate and major equipment, bank term loans, and SBA 7(a) loans, in roughly that order. Bank term loans had a median rate near 7% in late 2025, and SBA 7(a) rates are capped at 10.00% to 13.50% by loan size. All three require strong credit, operating history, and patience.

The 5 best options, ranked
1. SBA 504 loan Best rate for real estate and equipment
The CDC portion of a 504 loan is fixed at a below-market rate for 10 to 25 years, which is hard for any other small business product to match.
Watch for: Only for fixed assets. It cannot fund payroll, inventory, or other working capital. SBA loan guide →
2. Bank term loan Best rate for strong borrowers
A conventional bank loan has no guaranty fee and competitive pricing. It goes to businesses with solid financials and usually collateral.
Watch for: The slowest route outside SBA and the hardest to qualify for. Term loan guide →
3. SBA 7(a) loan Best low rate for general purposes
The SBA caps what a lender may charge, and the guaranty opens bank-level pricing to businesses that would not qualify conventionally.
Watch for: Heavy documentation, and the timeline rules it out for anything urgent. SBA loan guide →
4. Home equity line of credit Best low rate for owners with home equity
Secured by a home, a HELOC is priced near prime. It is cheap for a reason: the house is at stake.
Watch for: Your home is the collateral, even though the money funds the business. HELOC guide →
5. Equipment loan Best low rate without strong credit
Collateral lowers the lender's risk, so an equipment loan is often the cheapest product a mid-credit business can reach.
Watch for: Older or highly specialized equipment gets shorter terms and higher rates. Equipment financing guide →
Side-by-side comparison
| Option | Verdict | Cost basis | Funding speed | Qualifies on |
|---|---|---|---|---|
| SBA 504 loan | Best rate for real estate and equipment | CDC portion roughly 6.6% on 10 to 25 year terms | Weeks to months | Owner-occupied real estate or major equipment, plus a down payment |
| Bank term loan | Best rate for strong borrowers | About 7% median on new small-business term loans (Kansas City Fed, Q4 2025) | Weeks | Strong credit, established financials, often collateral |
| SBA 7(a) loan | Best low rate for general purposes | Capped at 10.00%–13.50% by loan size (prime plus the SBA maximum spread) | Weeks to months | Generally stronger credit and two or more years in business |
| Home equity line of credit | Best low rate for owners with home equity | Typically prime (7.00%) plus a lender margin | Slower than unsecured options: expect an appraisal and title work | Your home equity and personal credit |
| Equipment loan | Best low rate without strong credit | Representative 8%–30% APR, with the term matched to the equipment's useful life | Days to weeks | The equipment is the collateral, which can offset a thinner credit profile |
What it costs
SBA 7(a) rates are capped at prime plus a maximum spread that shrinks as the loan grows. At the current 7.00% prime rate, these are the highest payments a lender could charge on a 10-year term:
| Loan amount | Maximum rate | Monthly payment at the maximum |
|---|---|---|
| $100,000 | 13.00% | $1,493 |
| $300,000 | 11.50% | $4,218 |
| $1,000,000 | 10.00% | $13,215 |
Payments at the SBA maximum variable rate for each size tier. Many borrowers qualify below the maximum. Source for rate caps: U.S. Small Business Administration. WithFunded calculation.
What lenders look at
- Personal and business credit. The best rates go to the strongest files.
- Two or more years of tax returns showing the business can cover the payment with room to spare.
- Collateral and a down payment, where the loan is secured.
Mistakes to avoid
- Comparing a factor rate to an interest rate. A 1.25 factor is not 25% interest and usually costs far more on an annual basis.
- Choosing by rate alone. Fees, the term, and prepayment penalties change the total cost.
Frequently asked questions
- What is a good interest rate on a business loan in 2026?
- Bank term loans had a median near 7% in late 2025. SBA 7(a) loans are capped at 10.00% to 13.50%. Online loans span a wider representative 8%–30% APR.
- How do I qualify for the lowest rates?
- Strong personal and business credit, at least two years in business, healthy cash flow, and collateral where the lender asks for it.
- Why are low-rate loans slower?
- Because careful underwriting is how a lender can afford a low rate. Bank and SBA loans involve full financial review, and SBA loans add the guaranty process.

Landon and Austin were greatLandon and Austin were great. Knowledgable and explained everything in a way that made it all really easy to understand. I avoid these call like the plague but these two were a joy to work with.
Highly recommendedHighly recommended! I worked with Corey, and he was awesome. He found an option after I received multiple rejections that no other company had presented to me. It was within my budget and my timeline. I'm so thankful!
BTC has become my go to for working…BTC has become my go to for working capital. Recently, my company was in a bind and needed funds. The BTC team, headed by Drew, took a problem solving approach and helped to overcome an initial denial, resulting in a better facility than the one I was turned down for. Thanks BTC! Thanks Drew!

How we ranked these options
This guide ranks types of financing, not individual lenders. Each option is ordered by how well it fits the need described on this page, judged on four things in this order: whether the structure matches how the money will be used and repaid, total cost, funding speed, and how hard it is to qualify. Cost figures are WithFunded calculations from published rate inputs as of November 2026: the bank prime loan rate from the Federal Reserve, the SBA maximum-rate schedule, and Federal Reserve survey data. The method follows our 2026 SMB Financing Cost Report, whose own figures use June 2026 rates.
WithFunded is a financing marketplace, not a lender. Our 2-minute form suggests a product type from the families we cover, and a funding partner reviews the request. Not every structure named in this guide is available through WithFunded: options such as SBA microloans, USDA farm loans, bank loans, and seller financing are ones you would pursue directly with the provider. They are listed because leaving out a good fit would make the ranking less useful.
