The Personal Balance Sheet: What Net Worth Really Measures
In a hurry? Skip straight to the numbers.
Open the Net Worth Calculator →Net worth — everything you own minus everything you owe — is the single clearest measure of financial position, yet it is widely misunderstood as simply income or wealth. It is really a personal balance sheet, built on an accounting idea centuries old, and it captures something income alone never can.
Assets Minus Liabilities
Net worth is a snapshot, not a flow. It sums everything of value you own — cash, investments, property, possessions — and subtracts everything you owe — loans, mortgages, credit balances. The difference is your net worth. Unlike income, which measures money moving through your hands, net worth measures what you have actually kept and built.
An Idea From Double-Entry Bookkeeping
The personal balance sheet borrows directly from the accounting that has underpinned commerce for centuries. Double-entry bookkeeping, formalized in the Renaissance, arranged what a business owns against what it owes, with the difference being its worth. Applying the same structure to a household turns a jumble of finances into a clear, ordered statement of position.

Why Income Isn't Enough
A high income does not guarantee a high net worth. Someone earning a great deal but spending and borrowing heavily can have little or even negative net worth, while a modest earner who saves diligently can build a substantial one. Net worth reveals what income conceals: whether money is being accumulated or merely passing through on its way out.
A Number to Watch Over Time
The real value of net worth is as a trend. A single figure says little, but tracked over months and years it shows whether your financial position is strengthening or slipping. A steadily rising net worth is the clearest sign that saving, investing, and paying down debt are collectively working — the bottom line of personal finance.
