How to track your net worth (without linking your bank)

Your net worth is one number: everything you own minus everything you owe. It is the single most useful measure of financial progress, because it doesn't care where the money came from. Salary, side income, market returns and paid-down debt all end up in the same place.

Tracking it takes about ten minutes a month. Here is a routine that works, and none of it requires giving anyone access to your bank.

What to count

Add up your assets:

• Cash and bank accounts
• Investments: brokerage accounts, funds, shares
• Pension and retirement accounts
• Property, at a realistic sale price
• Anything else you could sell for meaningful money

Then subtract your debts:

• Mortgage
• Student loans
• Car loans and any consumer debt

The result is your net worth. Whether it is positive or negative today matters far less than the direction it moves over the next years.

Step 1: List your accounts once

Write one line per account or asset, and group them the way you think about them: Cash, Investments, Pension, Property. Put a house and its mortgage in the same group, so the group total shows your actual equity rather than a scary gross number.

This first session is the longest part. From then on you only update numbers.

Step 2: Pick a fixed day each month

The first of the month works well, or payday. The exact day doesn't matter; picking one and keeping it does. A consistent rhythm makes every point on your chart comparable, and it turns the update into a habit instead of a chore you renegotiate every time.

Step 3: Record the balances

Open each banking or broker app once, read the balance, type it in. For property, an estimate is fine; update it once or twice a year. Don't chase decimals. A number that is 2% off but recorded every month beats a perfect number you stopped recording in March.

Updating by hand sounds like a downside, but it is quietly the point: it is the one moment each month you actually look at all your money in one place. People who look regularly make better decisions. Awareness compounds, just like the returns do.

Step 4: Read the trend, not the month

Any single month is noise. Markets dip, a big bill lands, a bonus arrives. What matters is the 12-month direction: is the line rising, and is it rising fast enough for the goals you have set? If you save a fixed amount monthly, you will also start to see what the market adds or subtracts around your own contributions, which is a great cure for panic in a downturn.

Do you need to link your bank?

No. Account aggregators want your bank credentials or open-banking consents, and in return they update balances you only actually need once a month. For net worth tracking, automation solves a problem you don't have, and it costs you the monthly moment of awareness plus a copy of your transaction history sitting with a third party. One balance per account per month is enough.

Where to keep it

A spreadsheet works, and we wrote an honest comparison of spreadsheets and dedicated trackers. A purpose-built tool like Worthbook gives you the chart, group totals, goal tracking and a projection for free, without bank access, and you can always export everything to CSV. Whatever you choose, the habit is the point: ten minutes, once a month, same day.
