What is a loan agreement

A loan agreement is a contract in which one party, the lender, agrees to advance a sum of money to another party, the borrower, and the borrower agrees to repay it on defined terms, normally with interest. It fixes the amount, the rate, the repayment schedule, the conditions that must be met before money moves, what the borrower must and must not do while the debt is outstanding, and what counts as default.

The question that usually sits behind the definition is how a loan agreement differs from a promissory note. A promissory note is a one-way promise to pay. A loan agreement is the two-way contract that governs the relationship around that promise. The distinction matters because it decides whether the document can be transferred like an instrument. Under the Uniform Commercial Code (UCC), a note is negotiable only if it is an unconditional promise to pay a fixed amount of money and "does not state any other undertaking or instruction by the person promising or ordering payment to do any act in addition to the payment of money", apart from a short permitted list covering collateral, confession of judgment, and waiver of protective laws [3]. Covenants, conditions precedent, and reporting obligations are exactly the kind of additional undertaking that takes a document outside that definition. In most real transactions both documents exist: the loan agreement governs, and a note evidences the debt in transferable form.

The vocabulary is loose. Loan agreement, credit agreement, facility agreement, and loan facility agreement generally name the same instrument, with "facility" the usual word in commercial and syndicated lending. Personal loan agreement, business loan agreement, and family loan agreement name the same instrument aimed at different borrowers. A loan note or note purchase agreement is a different document, closer to the note side of the pair.

The meaningful subtypes are worth separating before anyone reads a draft:

• Term loan or installment loan. A fixed amount drawn once and repaid on a schedule.
• Revolving credit facility or line of credit. A limit the borrower can draw, repay, and redraw.
• Demand loan. Repayable whenever the lender calls it, with no fixed maturity.
• Secured or unsecured. Whether specific collateral backs the debt.
• Bilateral or syndicated. One lender, or a group acting through an agent.
• Consumer or commercial. The fork that decides which federal rules apply at all.

This is general information about how these contracts are built in the United States, not legal advice on a specific one.

Purpose and common uses of a loan agreement

A written loan agreement does four jobs a handshake cannot. It proves the money was a loan rather than a gift or an equity contribution. It fixes the price of the money and the schedule for returning it. It gives the lender something to enforce, and names the moment enforcement becomes available. And it records what the lender may take if repayment fails.

The consumer-or-commercial fork decides the regulatory weight of the document. Regulation Z, which implements the Truth in Lending Act (TILA), exempts "an extension of credit primarily for a business, commercial or agricultural purpose" and "an extension of credit to other than a natural person, including credit to government agencies or instrumentalities" [1]. A business loan therefore carries none of the consumer disclosure apparatus described later in this article, and a consumer loan carries all of it. Purpose, not the borrower's job title, is what the exemption turns on.

Common settings include bank term loans and revolving facilities for working capital, equipment financing, commercial real estate mortgages, loans partially guaranteed by the Small Business Administration, shareholder and intercompany loans inside a corporate group, seller financing in an acquisition, bridge and venture debt, and loans between family members.

That last one deserves its own paragraph, because it is where undocumented loans do the most damage. A loan carrying no interest or below-market interest is not simply cheap money in the eyes of the Internal Revenue Service (IRS). Under the below-market loan rules, forgone interest is "transferred from the lender to the borrower" and "retransferred by the borrower to the lender as interest", for gift loans, compensation-related loans, corporation-shareholder loans, and loans with federal tax avoidance as a principal purpose [5]. There is a de minimis exception for gift loans directly between individuals on any day when the aggregate outstanding amount between them does not exceed $10,000, but that exception "shall not apply to any gift loan directly attributable to the purchase or carrying of income-producing assets" [5]. The benchmark is the applicable federal rate (AFR), which the statute splits into short-term for instruments of not over 3 years, mid-term for over 3 but not over 9 years, and long-term for over 9 years, and which the Secretary determines during each calendar month for the following month [6]. The IRS publishes those rates monthly as revenue rulings [6].

The practical next action: before lending to a relative or a related company, look up the current AFR for the intended term and write the rate into the document.

Parties involved in a loan agreement

Two parties sign the core contract. Several more are usually bound by documents that sit alongside it.

The lender advances the money and holds the right to repayment. It is also called the creditor, the financier, the mortgagee where real property secures the loan, and the secured party where the UCC governs the collateral. In a syndicated deal the lenders act through an administrative agent and a collateral agent, which may or may not be the same institution, and which hold the security for everyone.

The borrower receives the money and owes it back. It is also called the obligor, the debtor, and the mortgagor. Where several entities borrow together as co-borrowers, they are normally jointly and severally liable, which means the lender may pursue any one of them for the whole balance rather than a share of it.

The guarantor promises to pay if the borrower does not. A guarantor signs a separate guaranty, not the loan agreement, and the scope of that separate document is often wider than the borrower expects. A personal guarantee from a company's owner is common on small business lending.

The pledgor grants the collateral. Usually this is the borrower, but a third party can pledge its own assets to secure someone else's debt, in which case it signs the security agreement without signing the loan agreement.

Other creditors are affected without being parties. Where a borrower has more than one lender, an intercreditor or subordination agreement sets who gets paid first and who may enforce.

Responsibility	Usual owner	Worth confirming in the contract
Funding the advance	Lender	Whether the commitment can be pulled, and on what grounds
Satisfying conditions precedent	Borrower	The deadline, and who decides the condition is met
Repayment of principal and interest	Borrower	Whether payments apply to interest, fees, or principal first
Financial reporting	Borrower	What is due, in what form, and how often
Maintaining insurance on collateral	Borrower	Who must be named as loss payee
Perfecting and maintaining the security	Lender	Who pays the filing and continuation costs
Releasing the lien after payoff	Lender	The deadline, and whether the borrower must ask
Calculating the benchmark rate	Lender or agent	The fallback if the benchmark stops publishing

Key terms and clauses in a loan agreement

Principal and facility mechanics. How much, drawn how, and when. A term loan funds once. A revolver sets a limit with availability tested at each draw. A delayed-draw facility sits between the two. Read the availability conditions, not just the headline number.

Interest rate. Fixed or floating. A floating rate is quoted as a benchmark plus a margin, and the benchmark is the part that changes without anyone renegotiating. The US transition away from the London Interbank Offered Rate (LIBOR) is the reason this clause deserves a fresh read on older paper. Under the federal LIBOR Act, for a LIBOR contract that contains no fallback provisions, or fallback provisions that do not identify both a specific benchmark replacement and a determining person, the Board-selected benchmark replacement became the benchmark by operation of law on the LIBOR replacement date [4]. That date is "the first London banking day after June 30, 2023", and the Board-selected replacement is "based on SOFR", the Secured Overnight Financing Rate, including a tenor spread adjustment [4]. If a document still says LIBOR, the rate it actually produces is probably not the rate it names.

Consumer disclosures. For closed-end consumer credit, other than the mortgage transactions that carry their own combined disclosures, Regulation Z requires the creditor to disclose a defined set of terms, including the identity of the creditor, the amount financed, the finance charge, the annual percentage rate (APR), the payment schedule, the total of payments, any variable-rate and demand features, prepayment and late-payment terms, and the property in which a security interest is taken [1]. The APR is the comparison number. The stated interest rate is not, because it excludes fees that the APR captures.

Repayment. Amortizing, interest-only with a balloon at maturity, or payable on demand. Confirm which, and confirm the first payment date, because it is frequently not one month after closing.

Prepayment. Whether the borrower may repay early, and what that costs. Prepayment penalties, yield-maintenance formulas, and lockout periods all appear in commercial lending, and a make-whole calculation can make an apparently cheap loan expensive to refinance.

Conditions precedent. What must be delivered before the lender funds: corporate approvals, legal opinions, insurance certificates, lien searches, appraisals, and executed security documents. Missing one of these is the most common reason a closing slips.

Representations and warranties. Statements of fact about the borrower at signing, and often repeated at each draw. An untrue repetition is typically an event of default even if nothing else went wrong.

Covenants. Affirmative covenants say what the borrower must do, usually reporting, insurance, tax payment, and maintaining its business. Negative covenants say what it must not do without consent, typically additional debt, additional liens, asset sales, distributions, and change of control. Financial covenants set ratios the borrower must hold, tested on fixed dates. These are the clauses that get breached quietly, because they are breached by an accounting result rather than by a missed payment.

Security and collateral. Where the loan is secured by personal property, UCC Article 9 governs. A security interest becomes enforceable only when value has been given, the debtor has rights in the collateral or power to transfer rights in it, and the debtor has authenticated a security agreement describing the collateral, unless the secured party instead has possession or control of the specific collateral types the statute lists [2]. The lender then perfects, normally by filing a financing statement in the public records.

Guaranty and support. Whose promise stands behind the borrower's, and whether the guaranty is of payment or merely of collection, limited or unlimited, continuing or transaction-specific.

Events of default. Non-payment, covenant breach, misrepresentation, insolvency, and cross-default to other debt. Cross-default is the one to read closely, because it lets trouble in an unrelated agreement accelerate this one.

Remedies. Acceleration of the whole balance, default interest, set-off against deposit accounts, and enforcement against collateral.

Boilerplate that is not boilerplate. Governing law, usury savings clauses, jury trial waivers, and assignment rights. Assignment matters commercially: most commercial loan agreements let the lender sell or participate out the loan, so the institution the borrower reports to in year three may not be the one it negotiated with.

Important dates and lifecycle events

The dates below are the ones that are actually missed. They are missed because they sit in different documents, and because several of them are counted backwards from a date nobody recorded.

• Signing date and funding date, separately. Interest, covenant tests, and maturity are usually measured from funding, not from signature.
• Conditions precedent deadline and commitment expiry. A commitment to lend normally dies if the conditions are not satisfied by a stated date.
• First payment date, and the recurring payment dates after it.
• Interest period ends and rate reset dates on a floating-rate loan, plus any election deadline for the next interest period.
• The rescission window on consumer credit secured by the borrower's principal dwelling. The consumer may rescind "until midnight of the third business day following consummation, delivery of the notice required by paragraph (b) of this section, or delivery of all material disclosures, whichever occurs last", and where the notice or the material disclosures are never delivered, the right expires "3 years after consummation, upon transfer of all of the consumer's interest in the property, or upon sale of the property, whichever occurs first" [1]. Residential mortgage transactions and certain refinancings by the same creditor are exempt [1].
• Financial covenant test dates and compliance certificate due dates. The certificate deadline usually falls weeks after the test date, so both belong in the diary.
• Insurance certificate expiry, since lapsed insurance on collateral is itself a covenant breach.
• Prepayment lockout expiry and penalty step-down dates, which decide when refinancing becomes affordable.
• Maturity date, and any extension option with its own notice window.
• Financing statement lapse. A filed financing statement "is effective for a period of five years after the date of filing", and on lapse the security interest it perfected "becomes unperfected, unless the security interest is perfected otherwise" [2]. A continuation statement may be filed "only within six months before the expiration" of that period [2]. This is a six-month window that opens four and a half years after closing, which is why lenders miss it.
• Cure periods attached to each event of default, which are short and which differ from each other within the same agreement.
• Lien release after payoff. The borrower's date. Final payment does not clear the public record by itself, and a stale filing surfaces during the next financing or sale.

Risks and common mistakes

Reading the note and not the agreement. The note states the amount, rate, and maturity, which looks like the whole deal. The covenants, conditions, and cross-default provisions live in the loan agreement, and they are what actually constrain the business.

Treating the loan agreement as transferable like a note. The additional undertakings that make a loan agreement useful are the same undertakings that keep it outside the definition of a negotiable instrument [3]. Transfer happens through the assignment clause, on the terms that clause sets.

Missing a covenant test date. A financial covenant breach is discovered by whoever prepares the compliance certificate, usually after the quarter it relates to has closed and the result can no longer be influenced. Diarising the test date rather than the certificate date is what creates room to act.

Assuming consumer protections apply. They do not apply to credit extended primarily for a business, commercial, or agricultural purpose, or to credit extended to an entity rather than an individual [1]. Borrowers sometimes expect an APR disclosure on a commercial facility and then compare quotes on stated rates that exclude different fees.

Leaving a legacy benchmark unread. A document that still names LIBOR now produces a SOFR-based rate by operation of federal law if its fallback language was inadequate [4]. The number in the model and the number on the invoice can diverge for a long time before anyone reconciles them.

Lending money to family or a related company without paperwork. Without a written rate at or above the AFR, the below-market loan rules can impute interest that nobody received [5] [6]. The document is cheaper than the tax analysis.

Letting the perfection lapse. For the lender, an unperfected security interest in a borrower's bankruptcy is close to an unsecured claim [2]. For the borrower, an un-terminated filing after payoff blocks the next lender.

Storing the loan documents separately. The agreement, the note, the security agreement, the guaranty, the insurance certificates, and every amendment are one obligation spread across six files. When they are stored apart, the dates in them are tracked by nobody in particular.

• What is a lease agreement. The practical comparison when financing equipment or premises, where a lease and a secured loan achieve similar economics through different ownership.
• What is a partnership agreement. The comparison when money going into a business could be structured as debt or as capital, which is the choice the loan documentation is evidence of.

Contract-management checklist

Capture at signature

1. Record the signing date and the funding date as separate fields, and record which one the term and the covenant tests run from.
2. Record the principal, the rate type, and for a floating rate the named benchmark, the margin, and one line summarizing the fallback.
3. Record the maturity date, and record any extension option with the date its notice window opens rather than the date it closes.
4. Record each financial covenant as its own line: the ratio, the threshold, the test frequency, and the first test date.
5. Attach the note, the security agreement, the guaranty, and every amendment to the same contract record as the loan agreement.
6. Record the collateral and the jurisdiction in which the financing statement was filed, with the filing date and the calculated lapse date.
7. Record whether prepayment is permitted, what it costs, and the date the lockout or penalty steps down.
8. Name an internal owner for the reporting obligations and a named contact at the lender.

Schedule reminders

9. A reminder before each financial covenant test date, early enough that the quarter can still be influenced, plus one on the compliance certificate due date.
10. A reminder before each periodic reporting deadline, whether monthly, quarterly, or annual.
11. A reminder before the insurance certificate expires, set to the certificate's own expiry rather than the loan's anniversary.
12. A reminder for the interest period election deadline if the facility carries one.
13. A reminder six months before the financing statement lapses, if you are on the lender side, plus one when the continuation window opens.
14. A reminder ninety days before maturity, so refinancing is a decision rather than an emergency.
15. A reminder after final payoff to confirm the lien release and the termination filing actually happened.

Review on a cadence

16. Every quarter, check the covenant results against the thresholds and confirm the certificate was delivered and acknowledged.
17. Every quarter, check whether any new debt, lien, distribution, or asset sale elsewhere in the business would breach a negative covenant in this agreement.
18. Once a year, map the cross-default clauses across every facility, so it is clear which agreements a single breach would accelerate.
19. Once a year, confirm the rate being charged matches the rate the document produces, particularly on any pre-2023 floating-rate paper.
20. Before any refinancing, sale, or new borrowing, pull every filing recorded in step 6 and confirm the public record matches the current position.

Most of what goes wrong on this list is record-keeping rather than drafting. The clause was there; the date was in a PDF nobody opened. Contracko keeps the loan agreement and its notes, security documents, guaranties, and amendments in one searchable repository, uses AI to extract parties, dates, amounts, and obligations from the documents, and supports custom fields for what this contract type needs tracked and a generic contract does not: the funding date, the benchmark and margin, each covenant threshold, and the financing statement lapse date. Expiration reminders cover covenant test dates, reporting deadlines, and maturity, and reporting shows the whole debt stack rather than one facility at a time. There is a free loan agreement review tool if you want to see what an agreement contains before loading it, a loan agreement to CSV extractor if you need the terms as structured data, and a free trial of the platform itself.
