Understanding Your Net Worth
What net worth means and why it matters
Your net worth is a single number that tells you where you stand financially. It is everything you own (assets) minus everything you owe (debts):
Net Worth = Total Assets - Total Debts
Unlike income, which tells you how much money flows in each month, net worth tells you how much wealth you have built over time. A doctor earning £100,000 a year with £200,000 in student debt and a large mortgage might have a lower net worth than a teacher who has been saving steadily for a decade.
For couples, tracking household net worth gives you a shared picture of your financial health and helps you measure progress towards your goals.
How to calculate household net worth
List your assets
Assets are everything you own that has financial value. For most UK households, this includes:
Liquid assets (easy to access):
- Current account balances
- Savings accounts and ISAs
- Premium Bonds
- Cash holdings
Investments:
- Stocks and shares ISAs
- Investment accounts
- Pension pots (workplace and personal)
- Cryptocurrency
Property and possessions:
- Your home (current market value)
- Other property
- Vehicles
- Valuable possessions (jewellery, art, collectibles)
List your debts
Debts are everything you owe to others:
- Mortgage balance
- Student loan balance
- Personal loans
- Car finance
- Credit card balances
- Buy Now Pay Later (BNPL) balances
- Overdrafts
- Any money owed to family or friends
Subtract debts from assets
For example:
| Item | Amount |
|---|---|
| Assets | |
| Joint current account | £4,200 |
| ISA savings | £12,000 |
| House value | £280,000 |
| Car | £8,500 |
| Total assets | £304,700 |
| Debts | |
| Mortgage | £210,000 |
| Student loan (Partner A) | £18,000 |
| Car finance | £5,200 |
| Credit card | £1,400 |
| Total debts | £234,600 |
| Net worth | £70,100 |
Why your net worth might be negative
If you are early in your career, have a mortgage, or carry student debt, your net worth may be negative. This is completely normal and not something to worry about. What matters is the trend — is it moving in the right direction over time?
Common situations where net worth is negative:
- Recent graduates with student loans
- Couples who have just bought their first home
- People paying off significant medical or legal bills
The key question is: are you making progress? If your net worth is increasing month by month, you are on the right track.
Setting net worth goals
Start with where you are
Do not compare your net worth to others. Everyone starts from a different place. Focus on your own trajectory.
Set realistic milestones
Break your long-term goals into smaller milestones:
- 3 months: Build a £1,000 emergency buffer
- 1 year: Pay off credit card debt, grow net worth by £5,000
- 3 years: Have 3 months of expenses saved, reduce mortgage by £15,000
- 5 years: Have 6 months of expenses saved, build investment portfolio
Track monthly, review quarterly
Monthly tracking keeps you accountable. Quarterly reviews let you spot trends and adjust your strategy. Property values and pension pots do not need updating more than every 3-6 months.
Using JoinFunds net worth tracker
JoinFunds brings all your financial information into one place so you can see your net worth at a glance.
Your bank accounts are already included
Every bank account you add to JoinFunds automatically contributes to your net worth calculation. Account balances update each time you import transactions.
Add your debts
Go to Net Worth in the sidebar and click the Debts tab. Add each debt with its current balance, interest rate, and monthly payment. JoinFunds includes a payoff calculator that shows when you will be debt-free.
Add your assets
Switch to the Assets tab and add property, vehicles, or other valuable items. Update values periodically to keep your net worth picture accurate.
View the big picture
The Overview tab shows a donut chart breaking down your financial composition. Green segments are assets, red segments are debts, and the centre number is your net worth.
For the most accurate picture, update your property value every 6 months using sites like Zoopla or Rightmove. Update your pension balance annually after receiving your statement. Import bank transactions monthly to keep account balances current.
Common mistakes to avoid
- Ignoring pensions — Your workplace pension is likely one of your biggest assets. Include it in your net worth calculation.
- Overvaluing your home — Use realistic estimates, not optimistic ones. Check what similar properties in your area have sold for recently.
- Forgetting small debts — BNPL balances, overdrafts, and money owed to friends all count.
- Checking too frequently — Daily net worth checks create anxiety over normal fluctuations. Monthly is the sweet spot.
- Comparing to social media — People share their wins, not their debts. Focus on your own journey.
