I was simplifying by saying that credit purchases go to expense.
But most items are expensed over a short term if not right away.
If you want to depreciate your refrigerator or stereo over a number of years and keep a carrying value, go ahead.
Most people do not wind up selling those items, they dispose of them. It will eventually go entirely to expense.
But most if the stuff you have does not contribute much to your net worth.
The purchase of a car of course becomes an asset.
It is large enough in value to say that it adds to your net worth, though it depreciates until it has very little residual value.
Now the purchase of a home becomes an asset classified as an investment.
This is because it generally does not depreciate and in fact tends to appreciate over time.
Whether or not there is any morgage borrowed against this asset does not change how it is classified on the balance sheet.
Same with a car. Whether you owe on it or not, you list it as a fixed asset and schedule depreciation.
Now to the other side of the balance sheet - the liabilities incurred by these purchases.
It's debt. Money you owe.
You have long term debt and you have short term debt.
Short term debt includes the next year's worth of mortgage payments and car payments. It would also include all your credit card debt whether you pay it off in a year or not since it does not have a payment schedule.
You can categorize these liabilites by any assets that they are secured by and list that in the detail.
So your net worth is:
Your cash plus carrying value of any assets such as cars and items you are able to sell plus investments such as 401K and the market value of your house - less all that you owe.
I just ask here- how much do you owe?
(Thinking about it more, a refrigerator usually stays with the house. It adds some to the value of the home but that addition is pretty much negligible. I'd just expense the refrigerator off the top)
