Net Worth Calculator 2026-27
Take stock of where you stand financially.
Calculate your total net worth in United Kingdom. Enter your assets — property, savings, investments, pension — and your liabilities — mortgage, loans, credit cards. Your net worth = assets minus liabilities.
Net worth is a snapshot. Track monthly for meaningful progress data.
Net worth = total assets minus total liabilities
Simple formula
Net Worth = Total Assets − Total Liabilities. Assets include everything you own that has monetary value: property equity, savings, investments, pension, vehicles, and other valuables. Liabilities are everything you owe: mortgage balance, personal loans, credit card balances, student loans.
Why track it?
Net worth is the single most comprehensive measure of financial progress. Unlike income (which can disappear), net worth represents accumulated wealth. Tracking it monthly reveals whether your financial decisions are building or eroding wealth.
UK median net worth by age group
| Age group | UK median net worth | Key milestone |
|---|---|---|
| Under 35 | £30,000–80,000 | Emergency fund + start investing |
| 35–44 | £80,000–200,000 | Mortgage reduction + pension growth |
| 45–54 | £200,000–450,000 | Peak earning, maximise contributions |
| 55–64 | £350,000–800,000 | Pre-retirement positioning |
| 65+ | £400,000–900,000 | Draw-down phase |
These are rough median estimates. Average figures are higher due to wealth concentration.
Three levers that grow UK net worth
UK Wealth and Assets Survey (ONS) data shows that households in the top net-worth decile consistently concentrate on three levers rather than cash hoarding: mortgage principal reduction, tax-advantaged investing, and asset allocation beyond on-call deposits. Each lever works on a different part of the balance sheet.
Lever 1 — Overpay the mortgage
Most UK residential mortgages allow up to 10% of the outstanding balance to be overpaid each year during a fixed-rate period without triggering an Early Repayment Charge (typically 1–5%). On a £250,000 mortgage at 4.5% over 25 years, paying an extra £200/month cuts the term by roughly 4 years and saves around £28,000 in interest — a direct, risk-free boost to net worth. Halifax, Nationwide, and Santander publish their ERC-free allowances in the mortgage offer documents; always confirm before pressing the overpay button in-app.
Lever 2 — Fill tax-advantaged wrappers
The HMRC annual ISA allowance is £20,000 per adult for 2026-27, and pension contributions receive tax relief at your marginal rate (20%, 40%, or 45%) up to the £60,000 Annual Allowance. A higher-rate taxpayer adding £10,000 gross to a SIPP reclaims £2,500 via self-assessment on top of the £2,000 claimed at source. Over 20 years at a 5% real return, that £10,000 becomes ~£26,500 — compared with ~£20,000 in a taxable General Investment Account paying dividend and capital gains tax annually.
Lever 3 — Allocate beyond cash
With CPI inflation averaging 2–4% in the post-2022 period, easy-access cash paying 3–4% Ofgem loses real value once Personal Savings Allowance is exhausted. A diversified allocation — low-cost global equity tracker, UK gilts, and a small cash buffer — has historically delivered 5–7% nominal returns. The FCA's guidance on investing is clear: cash is for money needed within 5 years; anything longer should have exposure to growth assets. FSCS protects cash up to £85,000 per banking licence; investments are protected up to £85,000 per platform for operational failure but not market losses.
UK net worth and Inheritance Tax thresholds
Once net worth passes certain thresholds, Inheritance Tax (IHT) starts to matter. IHT is charged at 40% on the part of an estate above the available nil-rate bands. Rising house prices mean many households now cross the threshold without realising it.
The two nil-rate bands
The Nil-Rate Band (NRB) is £325,000 per individual, frozen until at least April 2030. The Residence Nil-Rate Band (RNRB) adds £175,000 when the main home passes to direct descendants (children, grandchildren, including adopted and step). The RNRB tapers by £1 for every £2 of estate above £2,000,000 — fully withdrawn by £2.35m. Unused bands transfer to a surviving spouse or civil partner, so a married couple passing a home to children can shield up to £1,000,000 between them.
At what net-worth level does IHT matter?
| Net worth (single) | Indicative IHT exposure | Planning priority |
|---|---|---|
| Under £325,000 | £0 — within NRB | No IHT action needed |
| £325,000–£500,000 | £0 if home to children | Review will; claim RNRB |
| £500,000–£1,000,000 | Up to £200,000 (40%) | Use annual gifting, pensions, ISAs |
| £1,000,000–£2,000,000 | Up to £600,000 | 7-year PETs, trusts, BPR assets |
| Over £2,000,000 | RNRB tapering kicks in | Specialist estate planning |
Key reliefs and rules
Spousal exemption: transfers between UK-domiciled spouses or civil partners are fully exempt. Annual gift exemption: £3,000/year, plus £250 small-gift exemption per recipient. 7-year PET rule: gifts above the annual exemption fall outside the estate after seven years, with taper relief on tax charge between years 3–7. Pension pots currently sit outside the estate for IHT on death before 75, though the government has announced that most inherited pensions will be brought inside IHT from April 2027 — making near-term planning essential. Full rules: GOV.UK — Inheritance Tax.
Frequently askedFrequently asked questions
Is a negative net worth bad?
A negative net worth means your liabilities exceed your assets. It's common in early adulthood (student debt, car loans, small mortgage with little equity). It becomes concerning if it's not improving over time or if debts have high interest rates. The goal is a consistently rising net worth.
Should I include my pension in net worth?
Yes — pensions and retirement accounts are real assets. Many people underestimate their net worth by excluding them. Include the current transfer value for defined contribution schemes, and a calculated present value for defined benefit pensions.

Your result shows the projected growth or return based on the rate, contribution, and time period you entered — using standard compound or simple interest formulas.
Use this to set savings targets, compare investment options, or understand the impact of starting earlier. Adjust the rate and timeframe to model optimistic and conservative scenarios.
Not a guaranteed return. Actual investment outcomes depend on market conditions, fees, taxes, and timing that cannot be predicted with certainty.
Uses standard financial formulas with the inputs you provided. All calculations run in your browser — no data is sent to any server.
Savings and investment results are dominated by three factors: the rate of return, the time horizon, and regular contributions. Compounding amplifies all three over time.
Returns on returns accelerate growth over time. The difference between 5% and 7% over 20 years is much larger than the 2% gap suggests — compounding is non-linear.
Adding even small regular amounts dramatically increases the final balance. £100/week invested at 7% for 20 years grows to over £110,000 in contributions and £110,000+ in returns.
Starting 5 years earlier often produces a larger final balance than doubling your contribution rate. Time is the most powerful variable in savings calculations.
To improve your savings outcome, focus on starting earlier, increasing contributions, and minimising fees and tax drag on returns.
Starting with a small amount today and increasing over time beats waiting to start with a larger amount. Time in the market matters more than timing the market.
A 1% annual fee on a £100k balance costs £1,000/year and compounds against you. Compare fee structures across savings and investment products.
Super, offset accounts, and tax-free thresholds reduce the drag of tax on your returns — letting more of the growth compound for you.
