What is a Commitment Letter?
A commitment letter is a formal written document issued by a lender that confirms its intent to provide a business loan under specific terms and conditions, pending final approval and closing requirements. According to the SBA, commitment letters are standard practice in structured lending and typically remain valid for 60 to 90 days from the date of issuance.
How a Commitment Letter Works in Business Lending
A commitment letter is issued after a lender completes its initial underwriting review and decides to move forward with a loan offer. The document outlines the core terms of the proposed financing, including the loan amount, interest rate, repayment schedule, collateral requirements, and any conditions that must be satisfied before funding is released. These conditions — often called “conditions precedent” — may include a satisfactory appraisal, updated financial statements, proof of business insurance, or executed purchase agreements. Lenders such as SBA-approved institutions typically require borrowers to respond in writing within a defined window, often 10 to 30 days, to formally accept the commitment. The letter is not a guarantee of funding but represents a strong indication that the lender is prepared to close the loan if all conditions are met.
The role of a commitment letter varies across loan types. For SBA 7(a) loans, the SBA issues its own authorization document that functions alongside the lender’s commitment letter, and both must be satisfied before disbursement. Community banks and credit unions typically issue straightforward commitment letters tied to their internal credit approval process, with loan amounts commonly ranging from USD 50,000 to USD 5,000,000. Online lenders and alternative financing platforms may issue term sheets rather than formal commitment letters, which carry less legal weight but serve a similar informational purpose. CDFIs (Community Development Financial Institutions) often issue commitment letters that include mission-aligned conditions, such as job creation benchmarks or business location requirements tied to their funding mandates.
What Business Owners Should Do About a Commitment Letter
When you receive a commitment letter, read every condition carefully before signing. Each outstanding requirement represents a potential delay or deal-breaker if not addressed promptly. Create a checklist of all conditions precedent and assign realistic deadlines to each item. Common preparation steps include ordering a business or commercial property appraisal early, gathering two to three years of business tax returns, obtaining a certificate of good standing from your state, and confirming that your business insurance coverage meets the lender’s minimums. Pay close attention to the letter’s expiration date — most commitment letters expire in 60 to 90 days, and missing that window could require you to restart the underwriting process entirely. If the interest rate is variable, ask the lender about rate lock options to protect against movement during the closing period. Finally, have a qualified attorney or financial advisor review the document before you sign, as commitment letters may contain fee clauses or exclusivity provisions that limit your ability to seek competing offers.

What commitment letter do lenders require for a business loan?
Not all lenders issue formal commitment letters at the same stage, but most traditional lenders — including SBA-approved banks and credit unions — issue one after credit approval and before final closing. SBA 7(a) lenders issue an SBA Authorization document alongside the lender’s own commitment letter, both of which must be fulfilled for loans up to USD 5,000,000. Online lenders may substitute a term sheet for a formal commitment letter, though this carries different legal implications depending on your jurisdiction.
How does a commitment letter affect my interest rate?
A commitment letter locks in the proposed rate and terms as of the approval date, which can protect borrowers when interest rates are rising — particularly important given that the Federal Reserve’s 2023 Small Business Credit Survey noted tightening credit conditions across multiple lender categories. If the letter includes a variable rate tied to prime or SOFR, even a 0.50 to 1.00 percentage point increase during a lengthy closing process can meaningfully raise your monthly payment. Asking for a rate lock addendum at the commitment stage is a legitimate and often-granted request with many community banks and SBA lenders.
Can I get a business loan with poor commitment letter terms?
Yes — if the terms in a commitment letter feel unfavorable, you are generally not obligated to accept them, and you can continue shopping for better offers unless the letter contains an exclusivity clause. CDFIs and SBA Microloan intermediaries often offer more flexible structures for borrowers who have received high-rate or heavily collateralized commitment letters from conventional lenders. Secured options such as equipment financing or invoice factoring may also provide an alternative path to capital without requiring the formal commitment letter process that traditional term loans involve.
