Calculate total net worth by listing assets and liabilities with category breakdowns and net worth over time tracking.
Personal balance sheets rarely fit on one account statement, and the single number that ties them together is net worth: total assets minus total liabilities. This calculator collects what you own and what you owe in separate category lists, sums each side, and subtracts liabilities from assets. Each result can be saved as a dated snapshot, so later entries are compared against earlier ones to show a trend. The common mistake: listing income as an asset, or entering a financed home without its matching mortgage.
A concrete input and expected output from the current implementation.
Input
Assets: cash 8000, retirement 42000, home 350000, car 12000. Liabilities: mortgage 210000, car loan 5000, credit cards 2500.
Expected output
Total assets: $412,000. Total liabilities: $217,500. Net worth: $194,500. Largest asset: home, $350,000, about 85% of assets. Largest liability: mortgage, $210,000, about 96.6% of liabilities.
Net worth is the difference between the two totals: $412,000 in assets minus $217,500 in liabilities is $194,500. The category subtotals also reveal that one financed home dominates both sides of the balance sheet.
Entries are split into an assets side and a liabilities side, each tagged with a category such as cash, retirement, real estate, or vehicles. The tool sums both sides, computes net worth as total assets minus total liabilities, and shows subtotals per category so you can see concentration, such as how much of your assets sit in one home.
Each completed calculation can be stored as a snapshot carrying a date. When a new snapshot is saved, the tool compares it with earlier ones and reports whether net worth moved up or down between those points. Snapshots are only comparable when the same assets and liabilities are entered each time, so skip an account and the trend shifts even though nothing changed in reality.
Yes, at what they are worth today, with their loans listed as liabilities. Net worth is the whole balance sheet, not just investable money, so the house you live in counts. If your real question is what you could spend tomorrow, restrict the lists to liquid assets instead, because retirement funds and a primary home are not immediately spendable.
No, not by itself. The cash that pays the loan leaves the asset side while the loan leaves the liability side, so the two sides shrink equally and the difference between them is unchanged. Net worth measures the gap, not the size of either side. It does change the mix, and lenders generally prefer less debt, but the total moves only when the value of what you own changes.
