Net Worth Tracker: Which App Counts Property, Valuables and Debt?

Key takeaways

  • Net worth = everything you own minus everything you owe. An app that only sums bank accounts shows you liquidity, not wealth.
  • The largest items in a typical household have no transactions: the property, the car, the mortgage. Those are exactly the ones missing from many apps.
  • Test an app against four questions: can you add items without transactions? Is there a liabilities side? Is there a history? And can you get your data back out?
  • The trend matters more than the figure. A value without a timeline tells you nothing about your direction.

Anyone who takes managing their money seriously ends up at a single number sooner or later: net worth. It summarises what twelve account balances cannot. The only question is which app works it out honestly — and the answer is surprisingly often: none of them.

Why many apps give up at net worth

The reason lies in how they are built. Most finance apps grew around the bank connection: they fetch transactions, categorise them and build analysis on top. That works excellently for everything that produces transactions — salary, rent, shopping, subscriptions.

Except that the largest positions in an average household produce no transactions at all.

An app that only knows transactions cannot structurally represent these items. So it shows a sum across your accounts and calls it “wealth”. That is not miscalculated; it is the wrong question answered.

Four questions that identify a real tracker

QuestionWhy it decides
Can I add items with no transactions?Without pure value items you lose the property, the car, the valuables — often the largest part of your wealth.
Is there a liabilities side?Without remaining debt the figure is systematically too high. A home with a €380,000 mortgage is not wealth of €450,000.
Can I see a history?A single snapshot says nothing. Only the timeline shows whether you are making progress.
Can I get my data back out?Building wealth runs over decades. A history you cannot export is only on loan to you.

These four questions separate more reliably than any feature list. They cost you ten minutes in a trial.

The categories at a glance

There is no single right category — there is the one that fits the question you want answered.

CategoryAnswers wellBlind spot for net worth
Banking / multibankingWhat is my balance, what went out today?Everything without transactions; debt usually only as a payment
Budgeting appsWhat am I spending my money on?The asset side is largely missing
Portfolio trackersHow is my portfolio performing?Everything outside the portfolio
SpreadsheetsEverything — if you build it yourselfUpkeep; breaks once you leave it alone
Net worth appsWhat do I own in total, which way is it moving?Less depth on individual transactions

The table describes categories, not individual products: feature sets change constantly, and a comparison that is accurate today is stale in six months. Better to test the four questions above yourself, on whichever app you currently have open.

Work out your starting figure by hand once — it takes ten minutes and shows you immediately which items your app would need to know about:

What you own

Car, valuables — at what you would get today, not what you paid.

What you owe

Your net worth€35,000
Total assets€38,000
Total debt€3,000
Debt ratio8%

A negative result is a starting point, not a verdict. The number only means something over time.

The most common mistake: forgetting the loan

In practice the costliest mistake is not a forgotten valuable but a half-finished balance sheet. Enter the property at €450,000 without offsetting the €380,000 still owed, and you overstate your wealth by six times its actual value.

The consequence is not academic: an inflated figure invites bolder decisions than the situation supports. An app with no liabilities side encourages exactly that.

The reverse also holds: a negative net worth is more common than people think — after buying property, with student loans running, in the first years of a career. It is a starting point, not a verdict. All that matters is which way the number moves over the years.

sum is built around exactly this balance sheet. Accounts and portfolios sit alongside pure value items for property and valuables; loans and outstanding balances sit on the liabilities side — and out of that comes your net worth with history and breakdown. Today your transactions come in via CSV import; the automatic bank connection (PSD2) is in the works.

Frequently asked questions

What does a net worth tracker need to do?

It has to represent both sides of the balance sheet: accounts and portfolios, but also items with no transactions such as property and valuables — and on the other side loans and outstanding balances. An app that only sums bank accounts is not showing your wealth, it is showing your liquidity.

Why do so many finance apps not show a real net worth?

Because they are built around the bank connection. Anything without transactions never appears there — and in most households that is exactly where the largest items sit: the property on one side, the mortgage on the other.

How often should I update my net worth?

Once a month is enough. The figure fluctuates in the short term anyway; what carries meaning is the direction across quarters and years, not the daily value.

How do I value a property in a tracker?

With a realistic and rather conservative market value — not the purchase price and not the price you hope for. The remaining mortgage belongs on the liabilities side. Only the difference is genuinely your wealth.
