What it does
Net worth is what you own minus what you owe. List your assets (bank accounts, savings, investments, property, a car) and your debts (mortgage, loans, credit cards) and the total updates as you type, with a bar chart of where it sits.
If you want to watch it grow, save a dated snapshot each month and see the line. Snapshots are kept only if you tick the box, and only on your device. To plan the money coming in and out each month, use the budget planner; to keep track of what is due when, the bill calendar.
How to use it
- Change the example rows to your own: a name, a category and an amount for each asset and debt.
- Add more rows with Add an asset or Add a debt.
- Read the net worth at the top. Tick Remember if you want to save snapshots, then press Save a snapshot.
What each option does
- Remember my list and snapshots: off by default. When ticked, your list is kept in this browser only and is never sent anywhere. Untick it, or press Clear saved data, to remove it.
- Save a snapshot: records today’s assets, debts and net worth. Saving twice on one day replaces that day.
- Export / Import JSON: save your list and snapshots as a file, or load one back, for example on another device.
Worked example
Assets: current account 5,000 and savings 20,000, so 25,000. Debts: a credit card of 1,500. Net worth is 25,000 minus 1,500, which is 23,500. If you then add a car worth 10,000, it becomes 33,500.
FAQs
What value should I use for a house or car? What you could reasonably sell it for today, not what you paid. Use the same honest approach each time so the trend means something.
Should I include a pension? If you can see its current value, yes, as a retirement account. Leave out pensions that only pay later with no cash value.
Is my data safe? It never leaves your device. Nothing is stored at all unless you tick the box. To work out what share of your net worth something is, the percentage calculator helps. Not financial advice.
Where the numbers come from
- Net worth is assets minus debts. Values are whatever you type; nothing is looked up.
Standard scientific values, such as constants, atomic weights and melting points, are facts found in every textbook; we name where ours were checked. If you are an author or publisher and want a value, a credit or a table changed or removed, tell us and we will act quickly.
