When you lend money, borrow from someone you know, finance a private vehicle sale, or arrange repayment of an existing balance, a verbal promise may not give you enough protection. You need a written document that clearly explains who owes the money, how much is owed, when payments are due, and what happens if the borrower stops paying.
A promissory note helps you turn an informal promise into a documented repayment obligation. You do not need to fill the document with complicated legal language. You need accurate names, exact dollar amounts, realistic payment dates, clear interest terms, and signatures.
Before choosing one of the samples below, review How to Write a Promissory Note for a Personal Loan. That guide can help you decide whether your note should be secured, unsecured, interest-bearing, interest-free, payable in installments, or payable on demand.
You can also use 17 Promissory Letter for Payment Samples when you need additional wording for a promise to repay an existing balance.

Quick Answer Summary
A promissory note is a written promise to repay a specific amount of money according to stated terms.
Your note should clearly identify:

- The payment frequency
- The first payment date
- The final payment date or payoff rule
- The accepted payment method
- Any grace period or late fee

What Is a Promissory Note?
A promissory note is a written promise in which one party agrees to pay a fixed amount of money to another party. Depending on how you write it, the note may require installment payments, one lump-sum payment, interest-only payments, or repayment after a written demand.
You can use a promissory note for:
- A personal loan
- A family loan
- A loan between friends
- A private car purchase
- A business advance
- A tuition balance
- Past-due rent
- An unpaid service balance
- A short-term business loan
- A loan supported by collateral
- A loan involving a co-signer
A basic IOU may only acknowledge that money is owed. A promissory note usually goes further by explaining exactly how the debt must be repaid.
For a shorter acknowledgment of debt, use How to Write a Promise to Pay Letter.
Promissory Note vs. Loan Agreement
A promissory note focuses primarily on the borrower’s promise to repay the lender.
A loan agreement may include broader obligations for both sides, such as:
- Conditions that must be satisfied before funds are released
- Representations made by the borrower
- Restrictions on the borrower’s use of the money
- Detailed collateral requirements
- Insurance requirements
- Reporting requirements
- Dispute-resolution procedures
- Attorney-fee provisions
- Additional lender responsibilities
For a small personal loan, you may only need a straightforward promissory note. For a large loan, secured transaction, business loan, or complicated arrangement, you may need a complete loan agreement and professional legal review.
When your arrangement is a personal debt between two people rather than a new loan, Simple Debt Agreement Letter Samples may be a better starting point.
Promissory Note vs. Payment Agreement
You should generally use a promissory note when money is being loaned and the borrower is promising to repay it.
You can use a payment agreement when:
- An invoice is already overdue
- A customer owes for completed services
- A tenant owes past-due rent
- You are changing the repayment schedule
- The parties are resolving a disputed balance
- You are creating an installment plan for an existing debt
A payment agreement may confirm a balance without treating the transaction as a brand-new loan.
For an existing overdue obligation, review How to Write a Payment Agreement Letter before choosing your document.
What Your Promissory Note Should Include
Your note should be detailed enough that someone who was not involved in the original conversation can understand the arrangement.
1. The date of the note
Write the date on which the note becomes effective.
2. The borrower’s information
Include the borrower’s:
- Full legal name
- Mailing address
- Email address or telephone number, when appropriate
Do not rely only on a nickname or informal description.
3. The lender’s information
Include the lender’s full legal name and mailing address.
4. The principal amount
State the exact amount borrowed. For additional clarity, you may write the amount in both words and numbers.
Example:
Five Thousand Dollars ($5,000)
5. The interest terms
State the annual interest rate or clearly write that the loan carries 0% interest.
Do not leave the interest section blank. A blank section may create confusion about whether interest was intended.
6. The repayment schedule
Your note should explain:
- The amount of each payment
- When the first payment is due
- How often payments are due
- The recurring due date
- When the final payment is due
- Whether a balloon payment applies
7. The payment method
State whether the borrower will pay by:
- Check
- Bank transfer
- Money order
- Payment application
- Cash
- Online payment portal
- Another agreed method
When cash is permitted, require a signed receipt.
8. The application of payments
When interest applies, explain how payments will be credited.
A common approach is:
- Lawful fees and charges
- Accrued interest
- Principal
The order should comply with applicable law and your written agreement.
9. The grace period and late fee
State how many days the borrower has after the due date before a payment is considered late.
Any late fee should be reasonable and permitted under the law that applies to your transaction.
10. The prepayment rule
State whether the borrower may pay part or all of the balance early.
For many private loans, a simple provision allowing early payment without a penalty is the easiest option.
11. The default terms
Explain what counts as default. Examples may include:
- Missing a payment beyond the grace period
- Failing to make the final payment
- Refusing to repay the loan
- Selling pledged collateral without permission
- Providing materially false information about the loan or collateral
12. The lender’s remedies
Explain what the lender may do after default, subject to applicable law.
Possible remedies may include:
- Sending a written notice of default
- Giving the borrower time to cure the default
- Declaring the remaining balance due
- Enforcing a valid security interest
- Sending a demand letter
- Filing an appropriate legal claim
13. The collateral description
When the loan is secured, identify the collateral precisely.
For a vehicle, include:
- Year
- Make
- Model
- Vehicle identification number
- Title information, when appropriate
A promissory note that mentions collateral may not complete every step needed to create or perfect a security interest. You may need a separate security agreement, lien notation, filing, or other state-specific procedure.
14. The governing law
Identify the state whose laws will govern the note.
15. Signatures
At minimum, the borrower should sign and date the note. The lender should also sign when the note imposes obligations on both sides.
A co-signer, guarantor, witness, or notary should sign when your arrangement requires one.
How to Choose Your Payment Terms
The most protective payment plan is not necessarily the strictest plan. You need a schedule the borrower can realistically follow.
Installment payments
Use installment payments when the borrower receives regular income and can pay a fixed amount every week, every two weeks, or every month.
Example:
The borrower will pay $300 on the 15th day of each month beginning September 15, 2026.
Lump-sum payment
Use one lump-sum payment when the borrower expects to receive funds on a predictable date.
Example:
The unpaid principal and accrued interest will be due in full on December 31, 2026.
Interest-only payments with a balloon payment
You can use this structure when the borrower can pay interest now but expects to pay the principal later.
This arrangement creates a large final payment. Make sure the borrower understands the balloon amount and has a realistic plan for paying it.
Payable-on-demand terms
A demand note allows the lender to request repayment under the terms of the note.
You should still state:
- How the demand must be delivered
- How much notice the borrower receives
- Where payment must be sent
- Whether partial payments are permitted before a demand
Interest-free payments
You may choose 0% interest for a family or friend loan, but you should write “0% interest” or “No interest will accrue” directly in the document.
Certain below-market or interest-free loans may have federal tax consequences. The IRS publishes Applicable Federal Rates monthly, and federal tax law contains rules for certain below-market loans. You should consult a qualified tax professional when the amount is substantial or the arrangement may create tax questions.
Before You Use These Promissory Note Templates
Before you sign, confirm that you have:
- Verified the borrower’s legal name
- Verified the lender’s legal name
- Written the correct principal amount
- Chosen a realistic payment schedule
- Stated the interest rate or 0% interest
- Checked applicable interest-rate restrictions
- Defined the grace period
- Chosen a reasonable late fee
- Defined default
- Explained whether the balance can be accelerated
- Identified any collateral
- Explained how payments will be recorded
- Included prepayment terms
- Added the governing state law
- Required written changes
- Created copies for every signer
- Saved proof that the loan funds were delivered
When you are lending to someone close to you, discussing these details before the money changes hands may help prevent misunderstandings and protect the relationship. The CFPB also recommends writing down family-lending arrangements and giving everyone a copy.

What You Should Do When a Payment Is Late
When a payment is late, begin by reviewing the note. Do not immediately assume you can charge a fee, accelerate the balance, seize collateral, or file a claim.
Follow the written process.
Step 1: Verify your records
Confirm:
- The payment due date
- The grace period
- Whether the payment was received but not recorded
- The amount currently due
- The borrower’s contact information
Step 2: Send a respectful reminder
Your first message can be brief and factual.
State:
- The payment amount
- The original due date
- The accepted payment method
- How the borrower can contact you
Step 3: Send a written notice of default
When the note requires a formal notice, include:
- The date of the note
- The amount past due
- The missed payment date
- The applicable default provision
- The deadline to cure the default
- The method for making payment
Step 4: Consider a written adjustment
When the borrower has a temporary hardship, you may agree to a revised payment plan.
Document every change in writing. Do not rely on an oral promise to “catch up later.”
Use 17 Payment Arrangement Letter Samples when you need to propose a new installment schedule.
Step 5: Send a formal demand
When the borrower does not cure the default, you may need Demand Letters for Money Owed.
Your demand should remain accurate, professional, and consistent with the note.
Step 6: Evaluate your legal options
Before escalating, consider:
- The unpaid amount
- The applicable limitation period
- The borrower’s location
- The governing law
- Your evidence
- Filing costs
- Collection costs
- Whether collateral is involved
- Whether mediation is possible
When small claims court may be appropriate, use Demand Letter for Small Claims Court to create a final written record.
Do not threaten criminal charges, seizure, lawsuits, wage garnishment, or other remedies unless the statement is lawful, accurate, and appropriate for your situation.
How You Should Document Every Payment
Keep a payment ledger from the first payment through the final payoff.
Your ledger should show:
- Payment date
- Amount received
- Payment method
- Transaction or check number
- Amount applied to fees
- Amount applied to interest
- Amount applied to principal
- Remaining principal balance
- Notes about late payments or adjustments
Give the borrower a receipt when payment is made in cash.
Both parties should keep:
- The signed note
- Amendments
- Payment confirmations
- Bank records
- Copies of notices
- Email or text communications
- The final payoff confirmation
What You Should Do After the Loan Is Paid
When the balance reaches zero, the lender should provide written confirmation.
The payoff confirmation should identify:
- The borrower
- The lender
- The original note date
- The original principal amount
- The final payment date
- The fact that the balance is $0
- Whether the obligation is paid in full
- Whether any collateral interest will be released
Use 15 Sample Promissory Note Payoff Letters to document the final payment.
When collateral was used, the lender may also need to:
- Return original documents
- Release a lien
- File a termination statement
- Sign a title release
- Return pledged property
- Complete another state-required procedure
The borrower should keep the payoff letter and lien-release records permanently.
Common Promissory Note Mistakes You Should Avoid
Using vague repayment language
Do not write:
“Pay me back when you can.”
Write exact payment amounts and dates.
Leaving the interest section blank
State the annual interest rate or write that the loan is interest-free.
Charging an unlawful interest rate
Interest and fee limits may depend on the state, lender, borrower, transaction type, and loan amount.
Creating an unrealistic schedule
A payment plan that the borrower cannot afford may fail immediately.
Forgetting the final due date
State when the last installment or balloon payment is due.
Describing collateral poorly
Use serial numbers, VINs, title information, or other identifying details.
Assuming the note creates a completed lien
Additional documents, notices, title steps, or filings may be required.
Changing the agreement orally
Put every extension, reduction, waiver, or change in writing.
Accepting cash without receipts
Create a signed payment record for every cash transaction.
Leaving out the default process
Explain what counts as default and what notice must be provided.
Failing to give every party a copy
Each borrower, lender, co-signer, and guarantor should receive the complete signed document.
Forgetting the payoff letter
Close the account with written confirmation that the obligation has been satisfied.
Advanced Promissory Note Checklist
Use this checklist to review your parties, payment terms, interest, collateral, default provisions, signatures, records, and final payoff documents.
How to use this checklist: Check each item after confirming that it has been addressed in your final document.
Not every item applies to every loan. Mark only the provisions that match your transaction.
Frequently Asked Questions About Promissory Note Samples
Is a handwritten promissory note enforceable?
A handwritten promissory note may be enforceable when it clearly identifies the parties, states the amount owed, explains the repayment obligation, and contains the required signature.
However, a typed document is usually easier for you to read, copy, store, and present if a disagreement occurs.
Does your promissory note need to be notarized?
Not every promissory note must be notarized. Requirements can depend on your state, the transaction, and the type of collateral involved.
Notarization may help establish that a particular person signed the document, but it does not automatically make unclear or unlawful terms enforceable.
Can you create your own promissory note?
You can create your own note for a straightforward private loan. You should still consider legal review when:
- The amount is large
- Real estate is involved
- Valuable collateral is involved
- The borrower is a business
- Several borrowers are involved
- A co-signer is involved
- The borrower is already in financial distress
- The interest or fee terms are complicated
Can you charge interest on a personal loan?
You may be able to charge interest, but you must comply with applicable interest-rate and lending rules.
State rules may vary according to the parties, amount, loan purpose, security, and type of lender. Family loans may also raise federal tax issues.
Can you make the loan interest-free?
You can state that the loan carries 0% interest. For a substantial family loan or another below-market arrangement, you should ask a tax professional whether federal imputed-interest rules may apply.
The IRS publishes current Applicable Federal Rates each month.
Can your promissory note include collateral?
Yes. You should identify the collateral precisely and state that the note is secured.
However, you may need a separate security agreement, lien filing, title notation, mortgage, deed of trust, or other document. The required steps depend on the property and state law.
For real-estate-related examples, review Mortgage Promissory Note Samples.
What happens if the borrower stops paying?
You should follow the default procedure in the note.
That process may include:
- Confirming the missed payment
- Sending a reminder
- Providing written notice
- Allowing a cure period
- Offering a written adjustment
- Sending a formal demand
- Considering lawful collection or court options
Can you add a co-signer later?
You should not assume that simply adding someone’s name later creates a valid co-signer obligation.
Any new co-signer or guarantor should review the current note, understand the obligation, and sign properly drafted written terms. The borrower and lender may also need to sign an amendment or replacement agreement.
Can you change the payment schedule?
You can change the schedule when all required parties agree.
Put the new terms in a signed written amendment that identifies:
- The original note
- The old payment terms
- The new payment terms
- The effective date
- Whether all other provisions remain unchanged
For a client account, Payment Plan Letter to Client can help you document the revised schedule.
What should you do when the debt is disputed?
Do not use language stating that the borrower admits the full balance unless the borrower has actually agreed to that amount.
When both parties want to resolve a disputed account, you may need a settlement agreement rather than a standard loan note. Review How to Write a Debt Settlement Letter before finalizing the wording.
Is a promissory note the same as a contract?
A promissory note can function as an enforceable written obligation, but not every note will satisfy every legal requirement in every situation.
Its enforceability can depend on:
- The wording
- The signatures
- The consideration
- The legality of the terms
- The parties’ capacity
- Applicable state and federal law
- Whether required procedures were followed
- The evidence surrounding the transaction
Final Thoughts
A strong promissory note protects you by replacing assumptions with exact written terms.
Before money changes hands, you should agree on:
- The amount
- The interest rate
- The payment schedule
- The due dates
- The payment method
- The late-payment process
- The default process
- The collateral
- The prepayment rule
- The payoff procedure
Keep your wording clear and realistic. Save proof of the original transfer and every later payment. When the terms change, document the change in writing.
