The maximum spread varies by loan size and maturity. This cap ensures that borrowers are not charged excessive rates, aligning with the SBA's mission to provide affordable capital.","example":"A $1,000,000 variable rate 7(a) loan uses the Wall Street Journal Prime Rate. If the maximum permissible spread for this loan size and term is 3.00%, then the interest rate cannot exceed Prime Rate + 3.00%.","what_lenders_check":"Lenders must ensure that the interest rate, including the base rate and spread, never exceeds the SBA's maximum allowable cap. Violating the rate cap can lead to a guaranty denial.","required_facts":["Interest rate cap","Maximum allowable spread","Chosen base rate","Loan size","Loan maturity","SBA published maximum"],"source_families":["SOP 50 10 - Lender and Development Company Loan Programs","13 CFR Part 120 - Business Loans","7(a) Alternative Base Rate Options"],"official_sources":[{"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":"When is the use of the Wall Street Journal Prime Rate as the base rate mandatory for a variable rate 7(a) loan, if ever?","url":"https://dealroom.so/for-lenders/questions/when-is-the-use-of-the-wall-street-journal-prime-rate-as-the-base-rate-mandatory-for-a-var"},{"question":"What are the current allowable alternative base rate options for variable rate 7(a) loans, besides Prime Rate?","url":"https://dealroom.so/for-lenders/questions/what-are-the-current-allowable-alternative-base-rate-options-for-variable-rate-7-a-loans-b"},{"question":"What is the specific maximum interest rate a lender can charge on a variable rate 7(a) loan?","url":"https://dealroom.so/for-lenders/questions/what-is-the-specific-maximum-interest-rate-a-lender-can-charge-on-a-variable-rate-7-a-loan"},{"question":"Can a lender unilaterally increase the interest rate on a variable rate 7(a) loan?","url":"https://dealroom.so/for-lenders/questions/can-a-lender-unilaterally-increase-the-interest-rate-on-a-variable-rate-7-a-loan"},{"question":"What are the current alternative base rate options for variable rate 7(a) loans?","url":"https://dealroom.so/for-lenders/questions/what-are-the-current-alternative-base-rate-options-for-variable-rate-7-a-loans"},{"question":"How are variable interest rate adjustments determined for an SBA 7(a) loan?","url":"https://dealroom.so/for-lenders/questions/how-are-variable-interest-rate-adjustments-determined-for-an-sba-7-a-loan"}],"related_terms":[{"term":"Variable-rate 7(a) loan","url":"https://dealroom.so/glossary/variable-rate-7-a-loan"},{"term":"Interest rate cap","url":"https://dealroom.so/glossary/interest-rate-cap"},{"term":"Variable interest rate","url":"https://dealroom.so/glossary/variable-interest-rate"},{"term":"7(a) loan","url":"https://dealroom.so/glossary/7a-loan"},{"term":"Alternative Base Rates","url":"https://dealroom.so/glossary/alternative-base-rates"},{"term":"Variable Rate Loan","url":"https://dealroom.so/glossary/variable-rate-loan"}],"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":"2026-06-13","sba_rule_sources_checked_through":"2026-06-13"},"citation":{"label":"DealRoom.so SBA 7(a) Q&A","url":"https://dealroom.so/for-lenders/questions/how-is-the-interest-rate-cap-determined-for-a-variable-rate-7-a-loan","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."]}
