How to use it

  1. Choose the SBA program you're considering. The term options and loan limit update to match.
  2. Enter the loan amount. The rate defaults to the SBA cap for that size, and you can override it with your lender's quote.
  3. Leave the guarantee fee on to see the true net proceeds and APR, and add any packaging or closing fees.

How 7(a) rate caps work

Lenders price 7(a) loans as a spread over the Prime rate, and SBA limits the spread by loan size:

Loan amountMax variable rate
$50,000 or lessPrime + 6.5%
$50,001 – $250,000Prime + 6.0%
$250,001 – $350,000Prime + 4.5%
Over $350,000Prime + 3.0%

Fixed-rate caps are a little higher. Variable-rate loans reset when Prime moves, so the payment can change.

The guarantee fee

SBA guarantees 85% of 7(a) loans up to $150,000 and 75% above that (50% for Express). The upfront fee is a percentage of that guaranteed part, and it steps up with loan size. On a $500,000 loan, 75% is guaranteed ($375,000), and a 3% fee on that is $11,250.

What lenders will ask for

  • Two to three years of business and personal tax returns
  • A year-to-date P&L and balance sheet
  • A debt schedule, a business plan or use-of-funds statement, and projections for newer businesses
  • SBA Form 1919 and personal financial statements (Form 413) for each 20%+ owner

If SBA isn't the right fit

Compare against a conventional bank loan, equipment financing or a line of credit using the business loan calculator. Conventional loans can be faster, and there is no guarantee fee if your credit and collateral are strong.

Frequently asked questions

What is the current SBA 7(a) interest rate?

SBA doesn't set the rate, but it caps it. For variable-rate 7(a) loans over $350,000 the cap is Prime + 3%. Smaller loans allow bigger spreads, up to Prime + 6.5% at $50,000 and under. The calculator fills in the cap for your loan size.

Who pays the SBA guarantee fee?

The borrower. It's charged on the guaranteed portion of the loan, is usually financed into the loan, and varies by loan size and fiscal year. Microloans have no guarantee fee.

How long does an SBA loan take?

SBA Express and 7(a) Small loans from preferred lenders can close in 2 to 4 weeks. Standard 7(a) and 504 loans, especially with real estate, commonly take 45 to 90 days.

Do I need collateral?

Lenders must take available collateral for 7(a) loans over $50,000, but SBA won't decline a loan only because collateral is short. Owners with 20% or more of the business must personally guarantee it.
