Rates can be fixed or variable.","rule":"SBA 7(a) loan interest rates are typically variable, indexed to a base rate such as the Wall Street Journal Prime Rate, SOFR (Secured Overnight Financing Rate) as an alternative to LIBOR, or the SBA Peg Rate. Lenders add a \"spread\" or \"markup\" to this base rate, which is capped by the SBA based on the loan amount and term. Fixed rates are also possible, typically set at the current variable rate plus the maximum allowable spread.","example":"For a $300,000 loan, if the Prime Rate is 8.50% and the lender's allowed spread is 2.75%, the interest rate would be 11.25% (8.50% + 2.75%). This rate would adjust if the Prime Rate changes.","what_lenders_check":"Lenders must adhere to SBA's maximum allowable interest rates and spreads. They clearly disclose the base rate, spread, and frequency of rate adjustments to the borrower.","required_facts":["Base rate (Prime/SOFR)","Lender's spread","SBA rate caps","Fixed or variable"],"source_families":["7(a) Loan Program Terms, Conditions, and Eligibility","SOP 50 10 - Lender and Development Company Loan Programs","13 CFR Part 120 - Business Loans","7(a) Alternative Base Rate Options"],"official_sources":[{"title":"7(a) Loan Program Terms, Conditions, and Eligibility","url":"https://www.sba.gov/partners/lenders/7a-loan-program/terms-conditions-eligibility"},{"title":"SOP 50 10 - Lender and Development Company Loan Programs","url":"https://www.sba.gov/sites/default/files/2025-05/SOP%2050%2010%208%20Technical%20Updates%20effective%206.1.2025.docx"},{"title":"13 CFR Part 120 - Business Loans","url":"https://www.ecfr.gov/current/title-13/chapter-I/part-120"},{"title":"7(a) Alternative Base Rate Options","url":"https://www.sba.gov/sites/default/files/2026-02/Procedural%20Notice%205000-875051-%207%28a%29%20Alternative%20Base%20Rates.pdf"}],"related_questions":[{"question":"How is the interest rate on an SBA 7(a) loan decided, and what are the options?","url":"https://dealroom.so/sba-loans/basics/how-is-the-interest-rate-on-an-sba-7-a-loan-decided-and-what-are-the-options"},{"question":"Is there a maximum interest rate a lender can charge for an SBA 7(a) loan?","url":"https://dealroom.so/sba-loans/basics/is-there-a-maximum-interest-rate-a-lender-can-charge-for-an-sba-7-a-loan"},{"question":"Are SBA 7(a) loan interest rates always variable, or can they be fixed?","url":"https://dealroom.so/sba-loans/basics/are-sba-7-a-loan-interest-rates-always-variable-or-can-they-be-fixed"},{"question":"What factors determine the interest rate I will pay on an SBA 7(a) loan?","url":"https://dealroom.so/sba-loans/basics/what-factors-determine-the-interest-rate-i-will-pay-on-an-sba-7-a-loan"},{"question":"Is there a maximum interest rate that a lender can charge for an SBA 7(a) loan?","url":"https://dealroom.so/sba-loans/basics/is-there-a-maximum-interest-rate-that-a-lender-can-charge-for-an-sba-7-a-loan"},{"question":"What is the difference between a fixed interest rate and a variable interest rate on an SBA 7(a) loan?","url":"https://dealroom.so/sba-loans/basics/what-is-the-difference-between-a-fixed-interest-rate-and-a-variable-interest-rate-on-an-sb"}],"related_terms":[{"term":"SBA 7(a) loan","url":"https://dealroom.so/glossary/sba-7-a-loan"},{"term":"7(a) loan","url":"https://dealroom.so/glossary/7a-loan"},{"term":"Variable-rate 7(a) loan","url":"https://dealroom.so/glossary/variable-rate-7-a-loan"},{"term":"SBA 7(a) Loan Program","url":"https://dealroom.so/glossary/sba-7-a-loan-program"},{"term":"SBA 7(a) loan guaranty","url":"https://dealroom.so/glossary/sba-7-a-loan-guaranty"},{"term":"SBA 7(a) program","url":"https://dealroom.so/glossary/sba-7-a-program"}],"related_tools":[{"name":"SBA 7(a) payment & fee calculator","url":"https://dealroom.so/sba-7a/calculator"},{"name":"Find an active SBA 7(a) lender","url":"https://dealroom.so/lenders"}],"data_freshness":{"last_reviewed":"2026-06-14","sba_rule_sources_checked_through":"2026-06-14"},"citation":{"label":"DealRoom.so SBA 7(a) Q&A","url":"https://dealroom.so/sba-loans/basics/how-is-the-interest-rate-for-an-sba-7-a-loan-calculated","source_type":"DealRoom Q&A"},"caveats":["Grounded in the current SBA rulebook; verify against official sources before relying on it for a live deal.","Not legal, tax, or financial advice and not an approval decision."]}
