Net Worth Calculator

What net worth really measures

Net worth is the single clearest snapshot of your financial position, and the formula is deliberately simple: net worth = total assets − total liabilities. Assets are everything you own that has value — cash, savings, investments, the equity in a home, a car. Liabilities are everything you owe — credit-card balances, student loans, a mortgage, a car loan. Subtract what you owe from what you own and the result is your net worth. A positive number means your assets outweigh your debts; a negative number means the reverse, which is common early in life when student loans are large and savings are small. The figure matters less than its direction over time: a net worth that climbs year over year is the real signal of financial progress.

How this calculator works

You list your assets and liabilities as named line items with dollar values. The calculator sums each column, subtracts liabilities from assets, and shows three live cards — total assets, total liabilities, and net worth — that update the instant you change any number. Below them, an asset-allocation pie chart breaks down where your wealth sits, and a trend line plots saved snapshots over time. Everything is stored in your browser's localStorage, so your figures persist between visits on the same device and are never uploaded to any server. The default currency is US dollars, formatted to whole-dollar amounts.

Reading the asset-allocation pie

The pie chart divides your total assets into proportional slices, one per asset, computed as each item's value divided by the sum of all assets. Hovering a slice reveals its name, dollar value, and exact percentage. This view answers a question the bare net-worth number cannot: is my wealth concentrated or spread out? If a single slice dominates the circle — say 80% in one investment, or everything sitting in a checking account earning nothing — the chart makes that imbalance impossible to ignore. Liabilities are deliberately excluded from the pie, because allocation is about how your owned wealth is distributed, not your debts.

A worked example

Suppose you enter assets of $5,000 in checking, $15,000 in savings, and $30,000 in an investment portfolio — $50,000 total. Your liabilities are a $2,500 credit-card balance and a $20,000 student loan — $22,500 total. The calculator shows net worth of $50,000 − $22,500 = $27,500 in green, because it is positive. The pie chart splits your assets into 10%, 30%, and 60% slices, immediately showing that more than half your wealth rides on a single investment. If you then pay $2,500 off the credit card, total liabilities drop to $20,000 and net worth rises to $30,000 the moment you edit the figure.

Tracking the trend with snapshots

A net-worth number on its own is a single dot; the value comes from the line you draw through many dots. Click Save Snapshot to record today's net worth with the date. Once you have two or more snapshots, the trend chart draws a line connecting them, coloured green if your latest figure is at or above your first and red if it has fallen. Revisit the tool monthly, update your balances, and save a fresh snapshot each time. Over a year you build a personal net-worth chart that reveals whether your saving and debt-paydown habits are actually moving the needle — feedback no single calculation can give.

Common mistakes to avoid

• Counting gross instead of net for property. A house worth $300,000 with a $250,000 mortgage adds $50,000 of equity to your net worth, not $300,000. List the asset's full value and the loan as a separate liability — the subtraction handles the rest.
• Forgetting debts. A list of assets with no liabilities flatters your position. Include every balance you owe, even small recurring ones.
• Using wildly optimistic asset values. Net worth is only useful if it is honest. Value possessions at what you could realistically sell them for, not what you paid.
• Measuring too often and reacting to noise. Monthly or quarterly snapshots show the trend; checking daily just exposes you to market wiggles that mean nothing for your long-term trajectory.

Privacy and scope

Every number you enter stays on your device. The calculations, the charts, and the saved snapshots all live in your browser's local storage with nothing sent to a server, which is what makes it safe to enter real financial figures. Clearing your browser data or switching devices will reset the tool, so treat it as a personal planning aid rather than permanent record-keeping. It is a clarity tool, not financial advice — it shows you where you stand so you can make better-informed decisions about saving, spending, and paying down debt.
