How to Track Your Net Worth Monthly: A 20-Minute Review

Published November 8, 2026 · Updated November 8, 2026 · 6 min read · by the Sakura5 team

To track your net worth monthly, list everything you own and everything you owe on the same day each month, subtract the second total from the first, and write the result next to last month’s. Add one line for monthly cashflow (income minus spending) and you have the two numbers that matter. The whole review takes about twenty minutes once the list exists.

Net worth is the best single snapshot of your finances because it catches what a budget misses: a car loan shrinking, savings growing, an investment dropping. Cashflow tells you why the snapshot moved. Watching both once a month is enough to notice trends early without turning money into a daily obsession.

Below is what to count, a twenty-minute monthly routine, a worked example with round numbers, and a few figures worth tracking once the basics feel routine. This is a method for keeping score, not investment advice.

What counts toward net worth

Assets: what you own

• Cash: current accounts, savings, cash on hand.
• Investments: brokerage accounts, retirement accounts, funds, gold, crypto.
• Property and vehicles: at a conservative estimate of what they would sell for today, not what you paid.
• Money owed to you: only if you are confident it will come back.

Liabilities: what you owe

• Mortgage balance, car loans, student loans, credit card balances, personal loans, buy-now-pay-later plans, money borrowed from family.

Leave out things that are hard to sell or whose value is a guess: furniture, electronics, a collection you would never part with. Including them inflates the number and makes it jump around for no real reason.

How to track net worth monthly: the 20-minute review

1. Pick a fixed day

The first weekend after payday works for most people. Same day every month means comparisons are fair: you aren’t comparing a pre-salary balance with a post-salary one.

2. Update balances, not transactions

Open each account and write its current balance. You don’t need to categorise every coffee for a net worth review; that’s a budgeting job. Balances only, which is why twenty minutes is realistic.

3. Calculate the two numbers

Net worth = total assets minus total liabilities. Monthly cashflow = income received this month minus money spent this month. If cashflow is positive and net worth went down, an investment or property value probably fell. If cashflow is negative, net worth will follow sooner or later.

4. Compare with last month and with your target

Write the change since last month, and if you have a target (“net worth of X by the end of next year”), how far along you are as a percentage. Progress toward a goal is far more motivating than a raw balance.

5. Write one sentence

“Down because the car insurance was annual this month.” “Up mostly from the bonus.” One sentence per month turns a column of numbers into a history you can actually learn from in December.

A worked example with round numbers

Take someone reviewing on the first Saturday of the month.

• Assets: current account 3,200; savings 12,000; retirement fund 18,500; index fund 9,300; car worth about 11,000. Total 54,000.
• Liabilities: car loan 7,400; credit card 1,100. Total 8,500.
• Net worth: 54,000 − 8,500 = 45,500. Last month it was 44,300, so up 1,200.
• Cashflow: income 4,600, spending 3,700, so +900 this month.

The sentence for this month: “Up 1,200: about 900 from saving, the rest from the index fund.” Notice that cashflow explains most of the change. In a month where markets fall, net worth might drop even with the same +900 cashflow, and the sentence stops you from panicking about a number that is doing what markets do.

Numbers worth watching once the basics are routine

• Emergency fund in months: cash divided by monthly spending. Three to six months is a common guideline; the right number depends on how stable your income is.
• Yearly cashflow: twelve months of monthly cashflow added up. One bad month is noise; a negative year is a signal.
• A financial independence number: a widely quoted rule of thumb from retirement research such as the Trinity study is roughly 25 times your yearly spending, the amount that a 4% annual withdrawal would cover. Treat it as a rough horizon, not a promise.
• Debt as a share of assets: watching this fall is often more satisfying than watching assets grow.

Doing the review on your phone

A spreadsheet works if you already live in spreadsheets. Most people abandon theirs by month three because updating crypto prices, exchange rates and formulas becomes its own chore.

The money section of Life Management is built for this kind of monthly check. You list assets and liabilities, and it shows your net worth against your target, monthly and yearly cashflow, cash on hand, emergency-fund months and a FIRE number calculated as 25 times yearly expenses, compared against your cash. Crypto holdings and the USD exchange rate are priced live, so those lines update themselves. The finance tab can be locked behind Face ID or your passcode, which matters for numbers this personal. For people who trade, there is also a trading journal that records each idea with its time horizon, thesis and a pre-trade discipline checklist.

The rest of the app is a planner, so the monthly review can live as a recurring block in your timetable with the five steps above as its checklist. The interface is in Vietnamese at the moment. If you also want to put money goals on a calendar, our guide to how to plan your year with deadlines shows how to lay a savings target out as a stretch with quarterly milestones.

FAQ

How often should I track my net worth?

Monthly is the sweet spot for most people. Weekly tracking mostly records market noise and can push you toward reactive decisions, while yearly tracking spots problems too late to fix them cheaply. A fixed day each month, ideally just after payday, keeps comparisons fair and the review short. A net worth tracker that remembers last month’s figures makes the comparison automatic.

Should I include my house and car in net worth?

Include them at a conservative estimate of today’s sale value, and include the mortgage or loan against them as liabilities. Some people also track a second figure that excludes their home, because it shows how much is actually available. Whichever you choose, be consistent from month to month.

What is the difference between net worth and cashflow?

Net worth is a snapshot: everything you own minus everything you owe on one day. Cashflow is a movement: money in minus money out over a period, usually a month. Positive cashflow is what builds net worth over time; market changes move it up and down in between.

Is it normal for net worth to go down some months?

Yes. Annual bills, holidays and market drops all cause down months even when your habits are good. Look at the trend over six to twelve months and at your cashflow. A dip with positive cashflow is usually nothing to worry about; several months of negative cashflow deserve attention.
