Net worth is the value of everything you own (assets) minus everything you owe (liabilities). It is the single best snapshot of your overall financial position.

What counts as an asset?

Cash and bank balances, investments (stocks, bonds, funds, crypto), retirement accounts, the market value of property and vehicles, and any other items of meaningful resale value.

What counts as a liability?

Mortgages, student loans, car loans, personal loans, credit-card balances, tax owed, and any other money you owe to another party.

What is a good net worth by age?

A common rule of thumb is that target net worth equals (Age − 25) × Annual Income / 5. So a 35-year-old earning £50,000 should aim for £100,000. The calculator shows this benchmark next to your result.

Should I use market value or purchase price for property?

Always market value. Net worth measures what you could realise today — outdated purchase prices distort the picture in either direction.

About the Net Worth Calculator

The Net Worth Calculator answers the most important question in personal finance: what am I actually worth? The formula is simple — total assets minus total liabilities — but the discipline of writing everything down once a year is one of the highest-leverage habits in personal finance.

What to include — assets

Liquid: cash, current accounts, savings, ISAs, money-market funds.
Investments: stocks, bonds, funds, ETFs, crypto (at current market value).
Retirement: 401k, IRA, workplace pension, SIPP — at the latest provider statement.
Real estate: primary residence and any rental at current market value, not purchase price.
Vehicles: cars, motorcycles, boats — use a realistic resale figure.
Other: business equity, valuable collections (art, watches), royalties.

What to include — liabilities

Mortgages and HELOCs (outstanding balance, not original loan)
Student loans, car loans, personal loans
Credit-card balances (the part you carry month-to-month)
Tax owed but not yet paid (e.g. self-assessment liability)
Any private or family loans

Net worth target by age

A common benchmark from financial planning research is:

Target = (Age − 25) × Annual Income / 5

For example, a 35-year-old earning £50,000 should aim for around £100,000 net worth. This is a rough target — it ignores location, family structure and career stage — but it's a useful sanity check.

Frequently Asked Questions

Should my house count if I have a mortgage? Yes — but on both sides. Add the home's market value to assets, and the outstanding mortgage to liabilities. The difference (your equity) is what flows into net worth.

What about my car? Use a realistic private-sale value (Auto Trader, Kelley Blue Book or similar). Cars depreciate fast, so update the figure each year.

Can net worth be negative? Yes, often in the early 20s and 30s due to student loans and mortgages. The calculator shows the result with a minus sign.

How often should I recalculate? Annually is enough for a healthy snapshot; quarterly if you're working toward a specific savings or debt-payoff goal.
