Current SBA 7(a) loan rates – as of February 1, 2018

The SBA sets a maximum rate that SBA lenders may charge for their loans. These rates depend on the term of the loan and the principal amount of the loan. In October 2009 the SBA revamped how interest rates were charged to borrows for 7(a) loans. The current methodology includes two components to derive the interest rate – a “Fixed Base Rate” plus the “Allowable Interest Spread.” The fixed rate is the same for all loans and does very per month based on interest rates fluctuations. The Allowable Spread is constant and are designed to provide higher rates for are allowed to charge higher rates for smaller loans or loans with longer terms, which typically have higher costs and risks for banks.

Here is a summary of the current maximum rates SBA banks may charge for loans originating this month:

7 yrs or more$50,001 - $5M7.33%2.75%10.08%9.58%

The published SBA interest rates are good for the entire month, and new rates are published on the first of every month. Since the implementation of the current methodology in October of 2009, the fixed rate component has been as low as 4.44% (December 2012) and as high as 7.33% (February 2018). Fixed rates have been slowly rising over the past year and may continue to increase in the near future as the U.S. Federal Reserve has indicated a desire to return interest rates to historical levels.

Here is a historical view of the interest rates since the new SBA interest rate methodology was implemented in October 2009. Note that as mentioned above, there is a fixed rate, that changes every month (e.g., the blue line). Adding the allowable spread (which ranges from 2.25% – 4.75% based on the size and term of loan) sums to the total interest rate that may be charged. The chart below shows current rates for loans of $50,000 or more:

Fixed versus Variable Interest Rates for 7(a) loans

Rates for 7a SBA loans may be fixed or variable over time. With a fixed rate loan, the interest stays the same until the loan is paid off or retired. For variable rate loans, the interest rate may change periodically over time but the variable rate may not exceed the maximum allowed rate as set by the SBA. Banks prefer variable rate loans to reduce interest rate risks especially in periods where rates are anticipated to rise over time.

Other Fees and Expenses for SBA 7(a) Loans

In addition to interest charges, a “Guaranty Fee” on the portion of the loan that is guaranteed by the SBA. Typically the SBA will guarantee 75% – 85% depending on the loan. The Guaranty Fee structure depends on the size of the loan:

Loan AmountGuaranty Fee
$150,001 – $700,0003.00%
$700,001 – $1,00,0003.50%
Amount over $1,000,0003.75%

In addition, a fee of .25% is charged for loans of 12 months or less. A prepayment penalty for loans over 15 years may also be assessed during the first 3 years of a loan (5% for year 1, 3% year 2, and 1% during year 3).


Lastly, an ongoing fee of .546% if charged on all 7(a) Loans.


The vast majority in the 7(a) program are Express or Standard Loans. During last year, the SBA processed over $24 billion of loans (numbers below exclude 504 program):

Current SBA 504 loan rates – as of December 1, 2017

The SBA 504 loan program is for companies who are looking to purchase fixed assets – heavy machinery, real estate, etc. – so the use of funds is more restrictive than the more popular SBA 7(a) program. However, 504 loans can be a good fit for companies looking to make large purchases and need a 10 or 20 year term.

Interest rates charged for 504 loans is dependent on market conditions and a detailed explanation of this complicated program is beyond the scope of this article.  Suffice to say here that banks, Certified Development Companies (CDCs), and the secondary market determine pricing for 504 loans.
