Net Worth Calculator

• Assets - anything you own that has value: cash, investments, retirement accounts, property, vehicles, business interests.
• Liabilities - anything you owe: mortgage, loans, credit card balances, finance agreements, tax owed.
• Net worth can be negative. A recent graduate with student loans and little savings has a negative net worth. So does anyone who has just bought a house with a small deposit. It is a position, not a verdict.

Note. Net worth is a stock, not a flow. It measures what you have accumulated at one moment. Income measures what arrives - the two are related but neither predicts the other.

Excluding personal belongings is conventional because they are difficult to value accurately and seldom converted to cash. Including them makes the number look better without making you any more solvent.

Property is the largest asset most households hold, and the treatment is genuinely contested in personal finance.

• Include both sides - the market value as an asset and the mortgage as a liability. This gives the true equity position and is the more rigorous approach.
• Do not include only the asset - that inflates net worth by the entire outstanding mortgage and is the most common error.
• Do not net them off and then also list the mortgage - double counting is equally common.
• Consider also listing a separate "liquid net worth" - everything except the primary residence - because it shows what is actually accessible without selling your home.

A property decline of 10% cut total net worth by 19% while leaving liquid net worth untouched. Both figures are correct; they answer different questions.

1. Calculate it on a fixed schedule - monthly or quarterly, always the same way. Consistency matters more than precision.
2. Track the trend, not the reading. Markets move, property valuations are estimates, and one month means little.
3. Break it into components. Net worth can rise while cash falls and property rises; the composition tells you what is actually happening.
4. Set a target growth rate rather than a single number, and compare against savings rate and market returns.
5. Separate the effects you control - savings and debt repayment - from those you do not - market movements and property prices. Judging yourself on the market is a mistake.
6. Update valuations honestly. Carrying a vehicle at its purchase price or a house at its peak value produces a comforting number with no basis.
7. Do not compare against others. A high net worth may be inherited, leveraged, or concentrated in a single illiquid asset.

• Saving more than you spend - the only reliable driver, and the only one entirely within your control.
• Paying down debt - every dollar repaid raises net worth by a dollar, with a guaranteed return equal to the interest rate avoided.
• Investment growth - real but variable, and often the largest component in later years.
• Property appreciation - significant but illiquid and not guaranteed.
• Reducing liabilities is usually faster than waiting for markets in the early years, when debts are large relative to the asset base.
• Addressing a negative net worth works best by attacking high-interest debt first, building a small buffer alongside, and letting time and contributions do the rest.
