What is an SBA loan and how does it work?

An SBA loan is a government-backed loan where the Small Business Administration guarantees 75 to 85 percent of the loan, reducing risk for lenders and allowing better terms for small businesses. Common types include SBA 7(a) for general business purposes up to 5 million dollars, and SBA 504 for real estate and equipment up to 5.5 million dollars.

What are current SBA loan interest rates 2026?

SBA 7(a) loan rates in 2026 are based on the Prime Rate plus a spread, ranging from approximately 10.75 to 13.25 percent for loans over 350,000 dollars. SBA 504 rates are fixed at approximately 6 to 7 percent for the CDC portion, making it attractive for real estate and equipment purchases.

What is DSCR and why does it matter for SBA loans?

DSCR, or Debt Service Coverage Ratio, equals annual net income divided by annual debt payments. SBA lenders typically require a minimum DSCR of 1.15 to 1.25. A DSCR of 1.5 is considered excellent, meaning your business earns 1.50 dollars for every 1 dollar of debt payment owed.

What are SBA loan requirements for small businesses?

SBA loan requirements include a minimum credit score of 650, with 680 or higher preferred, at least 2 years in business, annual revenue typically above 100,000 dollars, a DSCR of 1.15 or higher, and a down payment of 10 to 30 percent depending on the loan type.

SBA Loan Calculator FAQs

What credit score do I need for an SBA loan?

Most SBA lenders require a minimum personal credit score of 650, though 680 or higher is preferred for the most competitive rates and terms. Your business credit history, time in operation, and financial statements also play a significant role in the approval decision.

How long does it take to get approved for an SBA loan?

Standard SBA 7(a) and 504 loans typically take 30 to 90 days for approval and funding due to extensive documentation requirements. SBA Express loans offer faster turnaround, often within 36 hours for the SBA decision, though full funding still takes additional time.

What is the SBA guarantee fee?

The SBA guarantee fee is charged on 7(a) loans over $150,000 and typically ranges from 2% to 3.75% of the guaranteed portion, increasing with loan size. This fee can often be financed into the loan amount rather than paid upfront, and fees are frequently reduced or waived for smaller loans.

Can startups qualify for SBA loans?

Yes, but options are more limited. SBA Microloans are specifically designed for startups and newer businesses, while standard 7(a) and 504 loans typically require at least 2 years of business history and established revenue, making them harder to access for very new businesses.
