Net Worth Calculator

Add up everything you own, subtract everything you owe, and see exactly where you stand today and where your current habits are taking you.

One Number That Sums Up Your Finances

Income tells you what came in this month. Net worth tells you what you have actually kept. Enter today's values below, then watch the direction the number moves each time you come back.

What You Own (Assets)

Current accounts, savings, cash ISAs, money market funds
Taxable brokerage, shares, funds, crypto — current market value
401(k), IRA, pension pot, provident fund balances
What your home and any other property would sell for today
Resale value, not the price you paid
Business equity, jewellery, collectibles, money owed to you

What You Owe (Liabilities)

Outstanding principal, not the original loan amount
Settlement figure on any vehicle finance
Total balance across all education debt
Balance carried, including any interest-free promotional debt
Unsecured loans, overdrafts, buy-now-pay-later balances
Tax owed, medical bills, money owed to family

Trend Assumptions

What you add to assets or take off debt in a year. Negative if you are drawing down

Benchmark & Debt Thresholds

Used for the age-and-income benchmark
Household gross income before tax and deductions
Benchmark = age × income ÷ divisor. 10 is the classic figure; raise it for a gentler target, set 0 to switch the benchmark off
Below this counts as comfortable. There is no legal threshold — lenders use their own
Above this counts as stretched. Adjust both bands to match your own risk tolerance

Understanding Net Worth

What Belongs on Each Side

The test for an asset is simple: could you sell it or spend it? The test for a liability is whether someone can demand the money back.

  • Include: bank balances, investments, pensions, property, vehicles, business equity
  • Exclude: your salary — that is a flow, and it shows up as net worth only once you have saved some of it
  • Exclude: an expected inheritance or a bonus not yet paid
  • Value at resale: a car bought for $35,000 three years ago may be worth $18,000 today, and that is the honest number

Why the Trend Beats the Number

A single net worth figure says almost nothing on its own. Two people with $200,000 are in completely different positions if one is climbing $30,000 a year and the other is falling $10,000.

  • Record the same figure on the same date each quarter, using the same valuation method
  • A rising trend through a falling market usually means your saving rate is doing the work
  • Expect a dip after a house purchase, a car purchase or a market correction — the slope over years is the signal
  • The change year to year is roughly what you saved plus what your assets earned, so a flat line means one of the two is missing

Reading the Debt-to-Asset Ratio

The ratio shows how much of your balance sheet belongs to lenders. It matters less than what the debt is buying and what it costs.

  • A high ratio from a recent mortgage on an appreciating home is normal and falls every month you pay it down
  • The same ratio built from credit cards at 20% and car finance on a depreciating vehicle is a different problem
  • Above 100% you are insolvent on paper: liabilities exceed everything you own
  • Lenders look at your debt-to-income ratio alongside this, because a balance sheet does not show whether you can make the payments

Common Ways People Overstate It

  • Purchase-price valuations: cars, furniture and electronics fall in value; homes do not always rise
  • Ignoring embedded tax: a $110,000 traditional retirement balance is worth meaningfully less after the income tax due on withdrawal
  • Forgetting transaction costs: agent fees, legal fees and transfer taxes take a real slice of any property sale
  • Omitting quiet debts: tax owed, buy-now-pay-later balances, an overdraft and money borrowed from family all count
  • Counting a business at a hoped-for price: use a figure a buyer would actually pay today
