When should you refinance a business loan?

When Refinancing a Business Loan Makes Sense

Business loan refinancing replaces an existing loan with a new loan — ideally at a lower rate, longer term, or both. The decision is purely mathematical: does the present value of the savings outweigh the cost of executing the refinance? Here are the five conditions where refinancing clearly makes economic sense.

• Your current rate is 200+ bps above today's comparable market rate — check the Fed H.15 and SBA rate floor for a reference point
• Your personal credit score has improved 50+ points since origination — you now qualify for a different pricing tier
• You need to lower monthly payments by extending the term (e.g., 24-month balloon → 60-month term loan) to preserve operating cash flow
• You are consolidating multiple higher-rate debts (multiple MCAs, multiple short-term loans) into a single lower-rate term loan
• You are eliminating a lender covenant, personal guarantee, or collateral pledge that is constraining your business operations

When NOT to Refinance

Three conditions make refinancing economically unfavorable: (1) Substantial prepayment penalty on the existing loan. If your current loan charges a 3–5% prepayment fee, this fee must be counted as an upfront cost of the refinance. On a $500,000 loan, a 3% prepayment fee is $15,000 — which may exceed the interest savings if the rate reduction is modest. (2) Closing costs exceed 5-year interest savings. Total the new loan's closing costs (origination, legal, SBA guarantee fee if applicable, appraisal) and divide by the monthly interest savings — if payback period exceeds 5 years, the refinance is likely not worth executing. (3) Restarting amortization significantly extends total interest paid. If you are 3 years into a 5-year term loan and refinance into a new 5-year loan, you are adding 3 years of interest on the outstanding balance. Calculate total interest paid over the full payoff timeline of both scenarios before deciding — the lower rate may not offset the extended amortization.

SBA Refinance Rules

The SBA permits refinancing existing business debt into a new SBA 7(a) loan under SOP 50 10 8 (effective June 1, 2025): the new loan's payment generally must be at least 10% lower than the existing payment, unless the debt already qualifies as 'unreasonable terms' — a demand note or balloon payment, a business credit card, a HELOC used for business, or a revolving line of credit the current lender won't renew — which bypasses the 10% test automatically. Refinancing an *existing* SBA-guaranteed loan into a *new* SBA loan is more restrictive: a different lender can do it under standard conditions (subsidy recoupment fees apply), but your original lender can only refinance it through non-delegated SBA procedures, and only in limited circumstances. SBA 504 loan proceeds can refinance conventional commercial real estate debt under the 504 Debt Refinancing Program if the original loan being refinanced is 'Qualified Debt' — meaning 85% or more of its proceeds were used to acquire the eligible fixed asset in the first place.
