Short answer
Record your net worth on the same day each month, with the same valuation rules, and keep every dated total. Judge the line over six to twelve months, not month to month, and split each change into what you saved from income, what markets did and what you revalued. Savings drive the trend; markets add noise around it.
Choose a cadence and keep it
| Cadence | Fits | Watch out for |
|---|---|---|
| Monthly | Most people; anyone paying down debt or building savings | Reacting to one month's market move |
| Quarterly | Stable finances, mostly long-term investments | Missing a spending leak for three months |
| Daily or weekly | Rarely useful | Market noise looks like progress or failure |
Use a fixed date — the 1st, or the day after payday — so each snapshot covers a full cycle. The same rule applies to valuations: one method for the house, one for pensions, one exchange-rate source. If you change a method, note it next to that month so the jump is explained.
Split every change into its causes
A month where net worth fell can still be a good month if you saved as usual and markets dipped. A month where it rose can hide a problem if the rise came only from a higher house estimate while card debt grew. Separating the causes is what turns a list of numbers into information.
One detail surprises people: paying off debt from savings does not change net worth on the day — cash and debt both shrink by the same amount. The gain shows up in the money you set aside from income to pay it, and later in the interest you no longer pay.
A six-month example
| Month | Net worth | Change | Saved | Markets |
|---|---|---|---|---|
| Jan | $41,200 | — | ||
| Feb | $42,900 | +$1,700 | +$1,500 | +$200 |
| Mar | $41,800 | −$1,100 | +$1,400 | −$2,500 |
| Apr | $44,100 | +$2,300 | +$1,600 | +$700 |
| May | $45,000 | +$900* | +$1,300 | +$400 |
| Jun | $46,700 | +$1,700 | +$1,500 | +$200 |
* May includes −$800 of car depreciation. Illustrative figures. Over five months net worth rose $5,500: $7,300 saved, −$1,000 from markets, −$800 car depreciation. March looked bad on its own; the savings column shows nothing went wrong.

Start my net worth historyReading the trend
- Look at the slope over 6–12 months. A three-month average smooths market swings.
- Compare growth with savings. Growth above what you saved means investments helped; below means losses, revaluations or a leak to find.
- Watch the debt line separately. Liabilities falling steadily is progress even when markets hide it.
- Look at liquid money too. A rising total with falling cash can mean the growth is locked in a house or pension — check your emergency fund.
Traps that make the line lie
- Vanity valuation. Raising the house estimate every month manufactures progress. Update it once or twice a year.
- Money that is not yours. A deposit held for someone else, or a shared account counted twice by two partners.
- Editing old snapshots. Correct a real error once, with a note; otherwise leave history alone.
- Reacting to one point. A single month is noise; decisions belong to the trend.
How Finman keeps the history
In Finman's net worth tracker the total comes from data already in the app — account balances, investments priced from Stooq, savings goals and manual assets, minus the remaining balance of each debt — converted to your base currency. “Save snapshot” stores the day's assets, liabilities and breakdown (one snapshot per day; saving again the same day replaces it). The trend view covers the last month, quarter, year or all time, shows the change since your previous snapshot, and appears once you have a few snapshots. The AI CFO chat uses your latest snapshot when you ask about your finances.

Frequently asked questions
How do I track net worth over time?
Calculate net worth on the same day each month with the same valuation rules, save each total with its date, and compare the totals over six to twelve months. Note what caused each change: savings, market moves or revaluations.
How often should I check my net worth?
Monthly suits most people; quarterly works if little changes. Checking daily mostly shows market noise.
My net worth dropped this month. Should I worry?
Split the change first. If you saved as usual and the drop came from investment prices, the trend is intact. If the drop came from spending or new debt, that is worth acting on.
Does paying off debt increase net worth?
On the day you pay, it stays the same: cash and the debt fall by the same amount. Net worth rises from the income you set aside to make the payment, and from the interest you no longer pay afterwards.
What is a good net worth growth rate?
There is no universal figure. Compare your own six- and twelve-month change with the amount you saved over the same period: growth above your savings means investments helped; below means market losses, revaluations or leaks.
