Free IOU Templates (Word)
Legal
by nadislavaskidan
An IOU puts a casual loan in writing so both people remember the amount, the date, and the promise to repay long after the handshake fades. This collection of 43 templates ranges from quick I-owe-you notes to fuller repayment agreements you can use between friends, family, or a small business and a client. It helps anyone lending money keep a friendly arrangement clear without hiring a lawyer or drafting legal language from scratch.
Each template opens in Microsoft Word, so you can type in names, the sum owed, and any repayment terms in a couple of minutes. An IOU is a simple acknowledgment of debt, not a substitute for a formal loan contract, so for larger amounts it's worth confirming what's enforceable where you live. Fill one in, print or email it, and keep a signed copy for your records.
When to use this IOU template
- A college student who just got their first summer job can use an IOU template to lend their parent $500 for a car repair, specifying the repayment terms and dates to avoid confusion later.
- A small business owner lending equipment to a local nonprofit needs a clear IOU to document the $2,000 value and expected return date before signing over the key.
- Friends splitting a large group expense—like a $300 birthday gift—can use a simple IOU note to track who owes whom and when, without awkward conversations months later.
- A landlord lending a tenant $1,500 for emergency repairs should use a structured IOU agreement to outline the repayment schedule and interest (if any) to protect both parties.

How to use this IOU template
Do these IOU templates include any legal protection for lenders?
These templates provide structure and clarity to your agreement, which can help avoid misunderstandings, but they are not legally binding contracts. For enforceable protection—especially for larger amounts—consider consulting a lawyer to review or modify the document. Think of these as starting points to document the promise, not as replacements for legal advice.
Can I use an IOU template to track interest on a loan?
Yes, some templates include fields for interest rates or fees, which can be useful for informal loans between trusted parties. However, if charging interest is part of a formal agreement or involves significant amounts, you may need a promissory note or other document to comply with local laws. Always check your state’s usury rules if interest is involved.
What’s the difference between an IOU for a personal loan and one for a small business?
Personal IOUs are typically simpler, focusing on the amount, repayment timeline, and signatures. Business IOUs may include additional details like collateral, late fees, or consequences for non-payment, depending on the relationship between parties. Choose a template that matches the formality of your agreement—personal loans can use a basic note, while business deals may need a more structured approach.
