What an Asset Is
An asset is anything you own that has real, recoverable value. That sounds broad, and in practice it is narrower than people expect. The test is simple: could you sell it, and would someone actually pay you roughly what you think it is worth?
Getting this right matters because every item you add moves your total. Overstate a few values and the number stops being useful to you.
The Clear Yes
Cash and savings balances. Checking accounts. Retirement accounts at their current balance. Brokerage holdings. Certificates of deposit. Real estate at current market value. Vehicles at what you could sell them for today, not what you paid for them.
For anything with a market price, use the market price. For anything without one, use a conservative estimate of what a buyer would realistically hand you.
The Gray Area
Furniture, electronics, clothing, and most collectibles technically qualify, but they lose value quickly and are hard to sell. If an item would not change your total by a meaningful amount, leaving it out costs you nothing and keeps the list honest. Larger exceptions are worth entering on their own: a paid off car, a serious instrument, jewelry or art with a documented value.
Conclusion
When you are unsure, ask whether you could convert the item to cash within a year at close to the value you assigned it. If the answer is no, lower the number or leave it off. A slightly conservative net worth is far more useful than an optimistic one.
