What is net worth?

Net worth is everything you own minus everything you owe. It is the simplest snapshot of your financial position and a useful number to track over time.

What counts toward your FIRE number?

FIRE planning usually focuses on investable assets that can produce income or be sold to fund spending. ISAs, taxable investments, cash, and accessible portfolio assets count more directly than your home or pension money you cannot access yet.

Liquid vs total net worth

Total net worth includes property and pensions. Liquid net worth is easier to access and excludes assets such as your home. For early retirement, liquid and investable net worth often matter more than the headline total.

About this calculator

The Net Worth Calculator helps you estimate assets minus liabilities and see the difference between total, liquid, and investable wealth. It is useful for financial planning, debt reduction, FIRE progress, mortgage conversations, estate planning, and tracking whether household wealth is actually growing over time.

Net worth formula

The calculator totals assets such as cash, savings, ISAs, pensions, investments, property, vehicles, and other valuables, then subtracts liabilities such as mortgage debt, loans, credit cards, car finance, and other debts.

net worth = total assets - total liabilities
property equity = property value - mortgage outstanding
liquid net worth = cash and accessible assets - short-term debts
investable net worth = cash + investments + pensions where included

How to use the net worth calculator

Enter cash, savings, ISAs, investments, pensions, property, vehicles, and other assets.
Enter mortgage balances, student loan balance if you want to include it, personal loans, credit cards, car finance, and other debts.
Use realistic current values rather than purchase prices for assets.
Review total assets, liabilities, property equity, liquid net worth, and investable net worth.
Compare the result with annual salary, annual spending, and FIRE progress if relevant.
Update the same categories monthly or quarterly so the trend is comparable.

Net worth examples

Positive net worth with mortgage debt

Input: Assets GBP 460,000 and liabilities GBP 205,000.

Calculation: GBP 460,000 - GBP 205,000.

Result: Net worth is GBP 255,000, but much may be tied up in home equity or pension value.

Debt repayment effect

Input: Credit-card debt falls by GBP 3,000 while assets stay the same.

Calculation: Liabilities reduce by GBP 3,000.

Result: Net worth improves by GBP 3,000 even without investment gains.

Total vs liquid net worth

Total net worth can include home equity, pensions, vehicles, and valuables. Liquid net worth focuses on money that is easier to access, such as cash and some investments. A household can have a high total net worth but still be cash-light if most wealth is in a home or pension.

Assets and liabilities to include

Assets: Cash, savings, ISAs, investments, pensions, property equity, vehicles, business interests, and valuable personal assets.
Liabilities: Mortgage debt, personal loans, credit cards, overdrafts, car finance, tax owed, and other debts.
Optional items: Student loans and household items can be included or excluded depending on the purpose, but be consistent each time.

Using net worth for planning

Net worth is most useful as a trend. A single month can move because of markets, house prices, or one-off expenses. A twelve-month trend shows whether debt repayment, saving, investing, and pension contributions are moving the household in the right direction.

Common mistakes

Using property purchase price instead of a current estimate.
Counting a pension as liquid cash.
Ignoring credit-card balances paid after the statement date.
Including joint assets but not joint debts.
Changing what is included each month and making the trend misleading.

Limitations

This guide is for general information only and is not financial advice. Asset values can change, pension access is restricted, and property estimates may differ from sale prices.

Frequently asked questions

Should I include my home?

Include it for total net worth, but track liquid net worth separately because home equity is not spendable cash.

Should pensions count?

They can count toward long-term net worth, but they may not be accessible until later life and may be taxed when withdrawn.

Should student loans be included?

It depends on why you are calculating. UK student loans work differently from normal debt, so be consistent with your chosen method.

How often should I update net worth?

Monthly or quarterly is enough for most people. Updating too often can make market noise distracting.

Is net worth the same as financial independence?

No. Financial independence usually depends on accessible/investable assets compared with spending, not just total net worth.

What does this mean?

This calculator is designed to help you understand the likely number before you make a decision or start an application.

Your result should be checked against official UK guidance, especially if your circumstances include dependants, exemptions, prior leave, or a complex immigration history.

Treat the figure as a planning tool rather than legal advice. Where the answer affects an application deadline or major payment, speak to an authorised adviser.
