Most of us have started a money spreadsheet at some point. It looks great on day one. By month three, a formula is broken, a tab is out of date, and you haven't opened it in weeks. That's not a discipline problem. It's a tool problem.
The good news is that tracking your net worth doesn't need tabs, formulas or a weekend of setup. It needs a short list, a regular date, and something that does the adding up for you. Here's how to do it in about 20 minutes a month.
Why Spreadsheets Quietly Stop Working
Spreadsheets are flexible. That's the upside and the problem. Because you can build anything, you usually build too much. A few things tend to go wrong:
- They break. One pasted value over a formula and your totals are wrong. You may not notice for months.
- They're hard to use on a phone. And your phone is where you actually are when you think about money.
- They don't show change well. Seeing how your number moved over a year means building a chart, and then keeping it working.
- They feel like homework. If updating takes an evening, you'll push it to next week. Then the week after.
None of this means spreadsheets are bad. It just means the best tracking system is the one you'll still be using next year.
Net worth is one sum: what you own minus what you owe. Anything that makes that sum harder to update is working against you.
What You Actually Need
Strip it back and you only need four things.
A list of what you own
Current account, savings, investments, pension or retirement accounts, crypto, and a fair guess for your home or car if you have them.
A list of what you owe
Mortgage, student loan, car finance, credit cards, and any buy now, pay later balances. Be honest here. This is just for you.
A regular date
Pick a day, like the first Sunday of the month, and put it in your calendar. Consistency matters far more than precision.
A way to see the trend
One number is a snapshot. Twelve numbers in a row tell a story. You want something that keeps that history without extra work.
A 20 Minute Setup
Here's a simple way to get your first number on the board. Grab a coffee and your banking apps.
- Open each account and note the balance. Don't worry about pennies. Round numbers are fine.
- Estimate the big stuff. For property, use a recent sale price of a similar home nearby. For a car, check a used car valuation site. Being roughly right is good enough.
- List your debts. Use the balance you'd need to pay today, not the monthly payment.
- Add both sides and subtract. That's your net worth for this month.
- Write down the date. Next month, you'll compare against it.
If the number is lower than you hoped, that's completely normal. Plenty of people start out negative, especially with student loans or a new mortgage. The starting point doesn't matter much. The direction does. Here's a deeper guide to calculating it if you want more detail.
How Often Should You Update It?
Once a month is the sweet spot. Weekly is too noisy, especially if you hold investments that move around. Once a year is too rare to learn anything from.
A monthly check takes five to ten minutes once you're set up. It's short enough to actually do, and frequent enough to notice when something changes, like a card balance creeping up or savings growing faster than you expected.
What to Do With the Number
Tracking is only useful if it changes something. After a few months, ask yourself three simple questions:
- Is it going up? If yes, great. Keep going and consider setting a milestone to aim for.
- What moved it most? Usually it's one or two things. A debt going down, or a savings habit sticking.
- What's one small change for next month? Cancel one subscription. Move a little more to savings. Pay a bit extra on a card.
That's it. No big plan. Just a small nudge, repeated.
Common Mistakes When You Start Tracking
A few small traps catch almost everyone in the first couple of months. Knowing them upfront saves a lot of second-guessing.
- Changing how you value things. If you used a cautious home estimate in month one, stick with the same method. Otherwise your number jumps around for no real reason.
- Forgetting small debts. A store card or a buy now, pay later plan is easy to miss, and it quietly makes your number look better than it is.
- Panicking over one bad month. Markets dip, big bills land. Look at the trend over three to six months, not a single snapshot.
- Getting discouraged by a negative number. It's more common than you'd think. Here's what to do if your net worth starts below zero.
Not sure whether your home belongs in the total? It's a fair question, and we break down both sides here.
Where an App Makes This Easier
You can do all of the above with a notebook. But a simple app removes the parts that make people quit. That's why we built Netvo.
You add your accounts once, then update balances whenever you like. Netvo does the maths, keeps your full history, and shows how your net worth has changed over time in a clean chart. You can set goals, track subscriptions, and get gentle insights from the AI Coach about where things are heading.
There's no bank login and no account to create. Your data stays on your device, with optional backup to your own iCloud or Google Drive. If you'd like to know why that matters, we wrote about it here.
Your net worth, minus the spreadsheet.
Netvo is free on iOS and Android. Add your accounts in minutes and watch your number move.
Frequently Asked Questions
Can I track my net worth without a spreadsheet?
Yes. All you need is a list of what you own, a list of what you owe, and a regular date to update both. A simple net worth app does the adding up and keeps your history, so there are no formulas to maintain.
How often should I update my net worth?
Once a month works for most people. It's often enough to spot trends and rare enough that it never feels like a chore.
Do I need to link my bank to track net worth?
No. Typing in a handful of balances once a month takes a few minutes and keeps your bank login out of third-party hands. Netvo is built for exactly this kind of private, manual tracking.
What should I include in my net worth?
Cash, savings, investments, retirement accounts, crypto, and a fair estimate for property and vehicles. Then subtract everything you owe: mortgage, loans, credit cards and any buy now, pay later balances.
