Most people have a vague sense of whether they are doing "okay" financially. They know roughly how much is in their bank account, and roughly how much they owe on their mortgage. But this fuzzy picture is not enough to make good financial decisions.
Net worth is the precise, complete measure of where you stand. It is the single number that tells the full story.
What Is Net Worth?
Net worth is simple:
Net Worth = Total Assets − Total Liabilities
If you own £200,000 worth of things and owe £80,000 in debt, your net worth is £120,000.
That is it. One number. No complexity.
Step 1: Add Up Your Assets
Assets are everything you own that has monetary value. List them all:
Liquid Assets (Can Be Accessed Quickly)
Retirement Accounts
Physical Assets
Total Assets = Sum of all of the above
Step 2: Add Up Your Liabilities
Liabilities are everything you owe:
Total Liabilities = Sum of all of the above
Step 3: Calculate
Net Worth = Total Assets − Total Liabilities
This number can be negative — especially early in life or after major purchases. A negative net worth is not a crisis; it is information. Many 25-year-olds with student loans and starter salaries have negative net worth. What matters is the trajectory.
What Does Your Number Mean?
There is no universal benchmark because net worth is deeply dependent on age, location, and income. However, some reference points:
| Age Group | Median Net Worth (UK, 2024 estimate) | |:---|:---| | 25-34 | ~£30,000 | | 35-44 | ~£100,000 | | 45-54 | ~£180,000 | | 55-64 | ~£270,000 |
For FIRE purposes, your target net worth is your FIRE Number — typically 25× your annual expenses. You can calculate yours at myfincalculators.com/en/fire/.
Why Track It Monthly?
A single net worth calculation is a snapshot. Monthly tracking creates a movie — one that reveals whether your financial habits are actually working.
1. You See Progress When Nothing Else Changes
Your salary might not increase this month. The market might be flat. But if you saved £800 and made your debt payments, your net worth moved. Seeing that movement — even £500 — maintains motivation.2. You Catch Problems Early
If your net worth stays flat for three months in a row despite saving, something is wrong: your debts are growing, or an asset is declining. Monthly tracking surfaces these issues before they compound.3. You Know Your FIRE Progress
If your FIRE Number is £600,000 and your net worth is £120,000, you are 20% of the way there. That is a powerful, concrete fact. Without tracking, it is just a vague aspiration.Building Net Worth: The Three Levers
1. Save More
Every pound saved that is not spent goes onto the asset side of your equation. Automate your savings — even £100/month, invested consistently, becomes significant. See our Compound Interest Calculator to see the numbers.2. Pay Down Debt Faster
Every extra pound paid on a loan reduces your liabilities. This increases net worth exactly the same as adding that pound to an asset. Overpaying a 15% credit card is equivalent to a guaranteed 15% investment return. See our debt payoff guide.3. Let Investments Compound
Assets that grow do not require your active effort. A £50,000 portfolio at 8% annual return adds £4,000 to your net worth this year without you doing anything. In 10 years, it adds £23,000 per year. This is why starting early matters so much.The Net Worth Calculator
