What Is a Promissory Note?

A promissory note is a legally binding written instrument in which one party — known as the maker, borrower, or promisor — makes an unconditional promise to pay a specified sum of money to another party — known as the payee, lender, or promisee — either on demand or at a defined future date. The note sets forth the principal amount of the debt, the interest rate (if any), the repayment schedule, the maturity date, and the consequences of default. Once signed by the maker, a promissory note creates a legally enforceable obligation to repay the debt according to the stated terms, and the payee can pursue legal remedies if the maker fails to perform.

It is important to distinguish a promissory note from a simple IOU and from a formal loan agreement. An IOU is merely an informal acknowledgment that a debt exists — it says "I owe you $5,000" but does not specify when or how the money will be repaid, what interest will accrue, or what happens if the debtor fails to pay. A promissory note, by contrast, contains all of these terms and constitutes a complete, enforceable promise to pay. A loan agreement goes further still: it is a bilateral contract signed by both the lender and the borrower that includes detailed covenants, representations, warranties, conditions precedent, and default provisions. For most personal and small business loans, a well-drafted promissory note provides all the legal protection the lender needs.

Under the Uniform Commercial Code (UCC) Article 3, a promissory note is classified as a negotiable instrument — the same legal category as checks and drafts. This means a promissory note can be transferred, endorsed, and negotiated to third parties, much like a check can be endorsed and deposited by someone other than the original payee. This negotiability is what allows promissory notes to be bought and sold in secondary markets, used as collateral for other loans, and bundled into mortgage-backed securities and other financial products. For a note to qualify as a negotiable instrument, it must contain an unconditional promise to pay a fixed amount, be payable on demand or at a definite time, be payable to order or to bearer, and not require any additional act beyond payment of money.

Promissory notes are used in an enormous range of financial transactions. Individuals use them to formalize personal loans between family members or friends, ensuring clear repayment expectations and satisfying IRS requirements for interest on below-market loans. Businesses use promissory notes to borrow working capital, finance equipment purchases, and document shareholder or partner loans to the company. In real estate, promissory notes are a fundamental part of every mortgage transaction — the note is the borrower's promise to repay the loan, while the mortgage or deed of trust provides the security interest in the property. Student loans, auto loans, and lines of credit are all documented with some form of promissory note.

Whether you are lending money to a friend, financing a vehicle purchase, structuring a business loan, or documenting a real estate transaction, a promissory note is your essential legal instrument for establishing the terms of repayment and protecting your right to collect. Our attorney-reviewed templates are designed to cover every critical provision, comply with UCC Article 3 requirements and state usury laws, and give you a professionally formatted document that stands up in court. Each template is customized for the specific type of promissory note you need — secured, unsecured, demand, installment, balloon, or convertible — and tailored to your state's legal requirements.

Types of Promissory Notes

Different lending situations call for different promissory note structures. A secured note backed by collateral is very different from a convertible note used in startup financing. Select the note type that matches your lending arrangement to get a template with the right provisions, payment terms, and legal language for your specific situation.

Promissory Note vs Other Documents

A promissory note is often confused with other debt and financial documents. Understanding the differences is critical for choosing the right document for your situation and knowing when you may need more than one.

Promissory Note vs IOU

Promissory Note

  • - Contains a formal, unconditional promise to pay
  • - Specifies interest rate, payment schedule, and maturity date
  • - Includes default provisions, late fees, and remedies
  • - Negotiable instrument under UCC Article 3
  • - Easily enforceable in court with clear terms

IOU

  • - Informal acknowledgment of debt only
  • - No payment terms, schedule, or interest rate
  • - No default provisions or remedies specified
  • - Not a negotiable instrument — cannot be transferred
  • - Difficult to enforce — requires proving additional terms

Bottom line: An IOU simply acknowledges that money is owed. A promissory note is a complete legal instrument that defines exactly how, when, and under what conditions the money will be repaid. Always use a promissory note instead of an IOU when lending money.

Promissory Note vs Loan Agreement

Promissory Note

  • - Unilateral — only borrower signs
  • - Focuses on the promise to repay
  • - Simpler, shorter document (1-4 pages)
  • - Negotiable instrument that can be transferred
  • - Ideal for personal and simple business loans

Loan Agreement

  • - Bilateral — both parties sign
  • - Includes lender's obligations and conditions
  • - More detailed document (5-50+ pages)
  • - Contains covenants, reps, warranties, conditions
  • - Required for complex commercial financing

When to use both: In commercial lending, it is standard practice to use both a loan agreement (which sets forth all terms and conditions) and a promissory note (which is the actual evidence of the debt). The loan agreement is the contract; the promissory note is the instrument that can be enforced and transferred.

Promissory Note vs Mortgage Note

General Promissory Note

  • - May be secured or unsecured
  • - Used for any type of loan or debt
  • - Does not require recording with the county
  • - Collateral can be any asset (if secured)
  • - Simpler default and collection process

Mortgage Note

  • - Always secured by real property
  • - Paired with a mortgage or deed of trust
  • - Mortgage/deed of trust is recorded with county
  • - Default triggers foreclosure proceedings
  • - Subject to TILA, RESPA, and state mortgage laws

Key distinction: A mortgage note is a specific type of promissory note that is secured by real property. The note itself is the promise to pay; the mortgage (or deed of trust) is the separate document that creates the lien on the property as security for the note. If the borrower defaults, the lender forecloses under the mortgage, not the note.

Promissory Note vs Bond

Promissory Note

  • - Private agreement between specific parties
  • - Not publicly traded on exchanges
  • - Terms are individually negotiated
  • - Typically shorter-term (months to a few years)
  • - Minimal regulatory requirements for private notes

Bond

  • - Tradeable security issued to the public
  • - Bought and sold on securities exchanges
  • - Standardized terms with a bond indenture
  • - Typically longer-term (5 to 30+ years)
  • - Heavily regulated by SEC and securities laws

In practice: Both promissory notes and bonds represent debt obligations. The key difference is that bonds are securities issued to a broad market of investors and are subject to securities regulation, while promissory notes are private instruments between identified parties. Selling promissory notes to the general public may trigger securities law requirements.

How to Write a Promissory Note: A 10-Step Guide

Writing a thorough promissory note requires careful attention to the terms of repayment and applicable legal requirements. Each provision serves a specific purpose, and omitting key terms can weaken the note's enforceability or leave the lender without adequate protection. Follow these ten steps to create a comprehensive promissory note.

1

Identify the Parties

Begin by clearly identifying the borrower (maker) and the lender (payee) using their full legal names. If the borrower is an individual, use their name as it appears on their government-issued identification. If the borrower is a business entity, use the exact legal name of the entity (LLC, Corporation, Partnership) along with the state in which it is organized and the name of the authorized representative signing on its behalf.

Include the mailing address of each party. If there are co-borrowers, each must be named individually and each will be jointly and severally liable for the debt unless the note specifies otherwise. If a guarantor is involved, they should be identified separately and a personal guarantee document should accompany the note.

Tip: Use the exact legal name of each party. Misspellings or informal names can create enforcement problems if the note needs to be collected through legal proceedings.

2

State the Principal Amount

Clearly state the principal amount — the total sum of money being borrowed — in both numerical and written form to eliminate ambiguity. For example: "$25,000.00 (Twenty-Five Thousand Dollars)." If the amounts conflict, most legal jurisdictions treat the written-out amount as controlling. The principal amount should reflect only the amount being lent, not including interest or fees.

If the loan will be disbursed in multiple draws or installments (such as a construction loan), specify the maximum principal amount, the draw schedule, and the conditions that must be met before each disbursement. The note should make clear that interest accrues only on the amount actually disbursed, not the total commitment.

3

Set the Interest Rate

Specify the annual interest rate as a percentage and indicate whether it is a fixed rate or variable rate. If variable, identify the index (such as the prime rate or SOFR) and the margin added to the index. State whether interest is calculated using simple interest (interest on principal only) or compound interest (interest on principal plus accrued interest), and specify the compounding frequency (monthly, quarterly, annually).

Before setting the interest rate, verify that it complies with your state's usury laws. Every state imposes a maximum legal interest rate for private loans, and exceeding this limit can result in forfeiture of interest, voiding of the note, or even criminal penalties. If the loan carries zero interest, the IRS may impute interest at the Applicable Federal Rate (AFR) for loans over $10,000, creating phantom income for the lender.

Warning:Charging interest above your state's usury limit can void the entire note or subject you to penalties. Check state usury laws before setting any interest rate.

4

Define the Payment Schedule

Specify exactly how and when the borrower will repay the loan. For installment notes, state the payment amount, frequency (weekly, bi-weekly, monthly), the date each payment is due, and the total number of payments. For demand notes, state that the full balance is payable upon demand by the lender and specify the number of days' notice required before payment is due (commonly 30 days). For balloon notes, define the periodic payment amount and the date and amount of the final balloon payment.

Indicate whether payments are applied first to interest and then to principal (the standard approach) or in some other order. Include the date of the first payment, the maturity date (final payment date), and the total amount the borrower will pay over the life of the loan including interest. Specify the acceptable payment methods (check, bank transfer, ACH, etc.) and the address or account to which payments should be sent.

5

Address Late Fees and Grace Periods

Define what happens when a payment is late. Include a grace period — typically 10 to 15 days after the due date — during which a late payment will not incur a penalty. After the grace period, specify the late fee: this is usually either a flat dollar amount (e.g., $25) or a percentage of the overdue payment (e.g., 5%), sometimes expressed as the greater of the two.

Some states cap the amount that can be charged as a late fee, so verify your state's requirements. Also specify whether a default interest rate will apply to overdue amounts — this is a higher rate of interest (e.g., 18% per annum) that kicks in after default to compensate the lender for the increased risk and cost of collection.

Tip: Reasonable late fees serve as an incentive for timely payment. Excessive late fees may be struck down by a court as unenforceable penalties. Keep them proportionate to the payment amount.

6

Include Prepayment Terms

State whether the borrower has the right to prepay the note in whole or in part before the maturity date, and whether a prepayment penalty will apply. Many personal and small business notes allow prepayment without penalty, which encourages faster repayment and benefits both parties. However, for longer-term loans where the lender relies on the interest income stream, a prepayment penalty may be appropriate.

If a prepayment penalty applies, specify the calculation method — common approaches include a percentage of the outstanding balance (e.g., 2%), a set number of months' interest, or a declining penalty that decreases over time. Some states restrict or prohibit prepayment penalties on certain types of consumer loans, so check your state's regulations.

7

Define Default and Acceleration

Clearly define what constitutes a default (event of default). Common triggers include failure to make a payment when due, breach of any term or condition of the note, bankruptcy or insolvency of the borrower, death of the borrower (if an individual), and material misrepresentation. For secured notes, default may also include failure to maintain insurance on the collateral, unauthorized sale or disposal of the collateral, or a material decline in the value of the collateral.

Include an acceleration clause that allows the lender to declare the entire remaining balance immediately due and payable upon default. Without this clause, the lender can only sue for each missed payment as it becomes due, which is impractical and expensive. The acceleration clause is the lender's most important protective provision. Also specify the remedies available to the lender, including the right to collect attorney's fees and costs.

8

Identify Collateral (If Secured)

If the note is secured, describe the collateral in sufficient detail to identify it clearly. For real property, this means a legal description and the street address; for vehicles, the year, make, model, and VIN; for equipment, serial numbers and descriptions; for financial assets, account numbers and institution names. A separate security agreement, mortgage, or deed of trust should also be executed to create and perfect the security interest.

The note should reference the security agreement and state that the lender's rights under the note are secured by the collateral described in that agreement. If the collateral is personal property, a UCC-1 financing statement should be filed with the state to perfect the lender's security interest. If the collateral is real property, the mortgage or deed of trust must be recorded with the county.

Warning: Failing to properly perfect a security interest (by filing a UCC-1 or recording a mortgage) means other creditors may have priority over your claim to the collateral. Always perfect your security interest promptly.

9

Add General Provisions

Include standard legal provisions (boilerplate) that protect the enforceability of the note. These typically include: governing law (which state's law applies), severability (if one provision is invalid, the rest of the note remains enforceable), waiver of presentment and demand (the borrower waives formal notice requirements under UCC Article 3), successors and assigns (the note binds heirs, estates, and successors), entire agreement (the note constitutes the complete agreement and supersedes prior negotiations), and amendments (the note can only be modified in writing signed by both parties).

Consider including a dispute resolution clause specifying whether disputes will be resolved through mediation, arbitration, or litigation, and in which jurisdiction. A choice of venue clause that designates the county or district where legal proceedings must be brought can also be valuable, particularly when the parties are in different states.

10

Execute the Note Properly

The borrower (maker) must sign and date the promissory note. While the lender's signature is not legally required for the note to be valid (since it is the borrower's promise), many practitioners include a signature line for the lender as an acknowledgment. If there are co-borrowers, each must sign individually. If the borrower is an entity, the authorized representative must sign on behalf of the entity, and their title should be included to demonstrate authority.

While notarization is not required in most states for a promissory note to be enforceable, it is recommended for notes involving large sums. If the note is secured by real property, the accompanying mortgage or deed of trust will need to be notarized and recorded. Electronic signatures are valid under the federal ESIGN Act and state UETA laws. Keep the original signed note in a secure location — the holder of the original note is the party entitled to enforce it.

Best practice:The lender should retain the original signed note. If the note is ever paid in full, the lender should mark it "PAID IN FULL," sign it, and return the original to the borrower as evidence the debt has been satisfied.

Interest Rate Rules for Promissory Notes

Interest is the cost of borrowing money, and the rules governing interest rates on promissory notes are a patchwork of state usury laws, federal regulations, and IRS requirements. Understanding these rules is essential for creating an enforceable note that does not expose the lender to penalties.

Usury Laws Overview

Usury laws set the maximum interest rate a private lender can charge on a loan. These limits vary by state and by loan type. Charging interest above the legal limit (usury) can have severe consequences: some states void the entire note, others require forfeiture of all interest (leaving only the principal owed), and a few impose criminal penalties including fines and imprisonment. The penalties for usury are strict because these laws exist to protect borrowers from predatory lending.

Simple vs Compound Interest

Simple Interest

Calculated only on the original principal balance. The interest charge remains the same each period regardless of how long the loan has been outstanding. Formula: Principal x Rate x Time. Example: $10,000 at 6% for 3 years = $10,000 x 0.06 x 3 = $1,800 total interest. Simple interest is the most common method for promissory notes between individuals and is easier to calculate and understand.

Compound Interest

Calculated on the principal plus any previously accrued but unpaid interest. Unpaid interest is added to the principal (capitalized), and future interest is charged on the larger balance. Example: $10,000 at 6% compounded annually for 3 years = $11,910.16 total, or $1,910.16 in interest (compared to $1,800 with simple interest). Compound interest results in higher total payments and must be clearly disclosed in the note. Some states restrict compound interest on consumer loans.

APR Disclosure Requirements

The Annual Percentage Rate (APR) represents the true annual cost of borrowing, including not just the stated interest rate but also fees, points, and other charges expressed as a yearly rate. Under the federal Truth in Lending Act (TILA), lenders who make more than a certain number of loans per year or who regularly extend credit must disclose the APR to consumer borrowers. While private individuals making occasional loans may not be required to provide TILA disclosures, including the APR in any promissory note is considered best practice and demonstrates transparency.

State Usury Rate Ranges

State usury limits for consumer loans generally fall into the following ranges, though exceptions exist for specific loan types, amounts, and licensed lenders:

Rate RangeExample States
5% - 8%New York (16% civil, 25% criminal), Connecticut (12%), Vermont (12%)
8% - 12%New Jersey (6%-30% depending on type), Pennsylvania (6%), Michigan (7%)
12% - 18%California (10% for personal loans), Florida (18%), Illinois (9%)
18% - 25%Texas (10% or 18% for commercial), Ohio (8%), Georgia (5% or contract rate)
No cap / high capNew Hampshire (no cap), Utah (no cap for written agreements), Colorado (45% consumer)

IRS Imputed Interest Rules

The IRS requires that loans between related parties (family members, business owners, etc.) exceeding $10,000 charge at least the Applicable Federal Rate (AFR) of interest. If no interest or below-AFR interest is charged, the IRS will impute interest — treating the forgone interest as income to the lender and potentially as a gift to the borrower. The AFR is published monthly by the IRS and varies based on loan term: short-term (3 years or less), mid-term (3 to 9 years), and long-term (over 9 years). Failure to charge at least the AFR can result in unexpected tax consequences for both parties. Always check the current AFR when structuring a below-market or zero-interest loan.
