You lent someone money. They said they'd pay you back. Now you can't remember the exact amount, whether they sent anything back, or what the balance is.
This is one of the most common financial headaches people face. And almost no budgeting app is built to solve it.
This guide covers the best ways to track money you lend to friends and family. You'll see which apps actually work, which ones fall short, and how to keep clean records without any awkward conversations.
Why Tracking Money You Lend Is So Hard
Most people reach for whatever is nearby when they lend money. A notes app. A quick text message. A mental note.
The problem is none of those systems are built for loans. They don't track partial repayments. They don't show a running balance. They don't tell you who still owes you money right now.
So the record gets blurry. Was it $18,000 or $20,000? Did they send $500 back in March or was that someone else? You're not sure anymore, and asking feels uncomfortable.
This isn't a trust problem. It's a tracking problem.
The Real Cost of Not Tracking
The obvious cost is not getting paid back. But there's a less obvious one too.
Money other people owe you is still your money. It's an asset. If you're calculating your net worth or planning a budget, that $20,000 your cousin owes you needs to be in the picture. Ignore it and your financial numbers are simply wrong.
What a Good IOU Tracker Needs to Do
A proper system for tracking money lent to friends needs to handle four things:
State | What It Means |
|---|---|
Lent | You gave someone money. The debt is open. |
Borrowed | Someone gave you money. You owe them. |
Paid | You paid back money you borrowed. |
Received | Someone paid you back (in full or in part). |
These four states cover every scenario. A loan starts as Lent. Partial repayments come in as Received. The balance updates each time. When the loan is cleared, the balance hits zero.
Most apps handle none of this. The ones that come closest were built for splitting dinner bills, not tracking a $20,000 family loan.
The Best Apps to Track Money You Lend (2026)
ExpenseSumo: Best for Tracking IOUs
ExpenseSumo is a privacy-focused manual expense tracker with a dedicated People and IOUs feature. It is the only personal finance app built around all four IOU states: Lent, Borrowed, Paid, and Received.
Here is how it works:
Log the loan. Go to People and IOUs, create an account for the person, and select Lent as the type. Then add a transaction, pick that account, and enter the amount, date, and any other details you want to keep.
Track repayments. When someone sends money back, add a Received entry for the same person. ExpenseSumo updates the balance automatically. You always know what is still outstanding.
See everyone at a glance. The Accounts screen has a People and IOUs category that lists every person you have a loan with, along with their outstanding balance.
Close the loan. Once a loan is fully repaid, it shows as Settled automatically. Tap on it anytime to see the full transaction history.
Key details:
Works on the free plan. No paywall for IOU tracking.
Manual entry only. No bank sync. Your data stays private.
Handles cash loans just as well as digital transfers.
Works for money you owe others, not just money owed to you.
The manual entry approach is worth noting. If you want automatic transaction import, ExpenseSumo is not that app. It is built for people who want to track intentionally, with full control over what goes in.

Splitwise: Best for Splitting Group Costs
Splitwise is a popular app for dividing shared expenses among a group. It works well for things like a group holiday, a shared apartment, or splitting a restaurant bill.
It is not built for one-sided loans. If you lend your brother $2,000 to cover rent, Splitwise has no clean way to record that. It works best when everyone in the group is using the app and the goal is to divide a shared cost evenly.
Works well for: Group trips, shared bills, roommate expenses.
Not great for: Personal loans, family lending, partial repayments on a single loan.
Venmo or Cash App Memos: Familiar but Limited
These payment apps are useful for sending money. The memo field lets you add a note. But a memo is not a ledger.
You cannot log a loan without a payment happening at the same time. You cannot track a cash loan at all. You cannot see a running balance as repayments come in. The history disappears into a long feed of unrelated transactions.
Works well for: Small same-day repayments between friends.
Not great for: Anything you need to track over weeks or months.
A Spreadsheet: Flexible but Fragile
A spreadsheet can work if you build it well and keep it updated. You would need columns for the person, the date, the amount, the direction (lent or borrowed), repayment entries, and a running balance.
The problem is one missed entry breaks the whole thing. And most people do not keep a spreadsheet updated on their phone after the fact.
Works well for: People who love building their own systems.
Not great for: Anyone who wants something simple that just works.
How to Track a Loan Step by Step (Using ExpenseSumo)
Here is a simple walkthrough for a real scenario. You lend your cousin $20,000 for a car.
Step 1: Go to Accounts, tap Add Account, choose People and IOUs, select Lent, and enter the name "Cousin Marco."
Step 2: Add a transaction, select that account, and enter $20,000 along with the date and a note like "Honda Civic loan."
Step 3: A few months later, Marco sends you $5000. Add a new transaction, select Received, pick Marco's account, and enter $5000. The outstanding balance updates automatically to $15,000.
Step 4: Check the Accounts screen anytime under People and IOUs to see the current balance for every person.
Step 5: When Marco pays the remaining $15,000, add the final Received entry. The account shows as Settled. Tap it anytime to see the full repayment history.
No spreadsheet, no memory required.
Final Thoughts
Lending money to friends and family is normal. Losing track of it is also normal, but it does not have to be.
The right tool treats your IOUs as real financial records, not afterthoughts buried in a notes app. Track the original loan, log each repayment, and always know the current balance. That is all it takes to stay clear and protect both your money and your relationships.
ExpenseSumo is built for exactly this. The People and IOUs feature is free, private, and takes about 30 seconds to log a loan. Start tracking for free at expensesumo.com.
Frequently Asked Questions
Is there a free app to track money I lend to friends?
Yes. ExpenseSumo includes full IOU tracking on the free plan. You can log loans, track partial repayments, and see outstanding balances for every person, all without paying anything.
What is the best IOU tracker app in 2026?
For personal loans between friends and family, ExpenseSumo is the most purpose-built option available. It is the only app with all four IOU states: Lent, Borrowed, Paid, and Received. Splitwise is better for splitting group expenses, but it was not designed for one-sided loans.
How do I track partial repayments on a loan?
In ExpenseSumo, log each repayment as a Received transaction linked to the same person. The app updates the running balance each time. You always see the current outstanding amount, not just the original loan total.
Can I track cash loans, not just bank transfers?
Yes. ExpenseSumo is a manual tracker, so you enter transactions yourself. This means cash loans are tracked the same way as any digital transfer. This is actually an advantage over apps that rely on bank sync, since those apps cannot see cash at all.
Is it strange to keep records when lending money to family?
Not at all. Clear records protect the relationship, not just the money. Disputes about loan amounts or repayment history almost always happen because no one kept a record, not because of bad intentions. A simple log removes the ambiguity before it becomes a problem.
