Net worth calculator 2026/27
What you own less what you owe — and then the part every other net worth calculator leaves out: how much of it is tax you have not paid yet.
Calculator
What you own
Current accounts, savings accounts, premium bonds. Add them up — there is one box because they are all taxed the same way. The capital is never taxed; the interest can be, which is what the emergency fund and savings calculators price.
Cash, stocks and shares, innovative finance and Lifetime ISAs together. This is the one row worth exactly what it says: nothing inside an ISA is taxed on the way out.
A general investment account, shares held directly, funds outside an ISA or pension. Enter what they are worth today.
Today's value less what you paid. This is the part capital gains tax is charged on — not the value above it. Leave it at £0 if you do not know; the answer then treats the account as though it had no gain in it, which understates the tax.
Workplace pensions, personal pensions and SIPPs — the pot value on your statement. 25.00% of it is tax free and the rest is taxable income whenever it is drawn, which is why this row is not worth its balance. A defined benefit or final salary pension is not a pot and does not belong here.
What it would sell for, before the mortgage — the mortgage is a liability below. Selling your only home is normally free of capital gains tax, so no tax is charged on this row.
Vehicles, valuables, a business, a second property, anything else. No tax is priced on this row, and for a second property or a business that is an understatement rather than a rounding — see the note under the answer.
What you owe
The balance outstanding, not the monthly payment.
Loans, credit cards, overdrafts, car finance. A student loan is deliberately not listed: it is repaid as a percentage of income and written off, so treating it as a debt against your assets misstates both.
What decides the tax
Salary, self-employed profit, rent, pension already in payment. It decides the rate a pension withdrawal is taxed at and which capital gains rate the gain meets, because both stack on top of the income you already have.
The residence nil-rate band applies only where a home is inherited by direct descendants — children, grandchildren, step, adopted and foster children and their spouses. Nephews, nieces, siblings and friends are not direct descendants.
Transfers between spouses and civil partners are exempt without limit, so there is no inheritance tax on the first death. The unused bands transfer — and the residence band still tapers on that first death, which is the part that surprises people.
Income tax on a pension withdrawal is devolved. Capital gains tax and inheritance tax are not — they are the same across the UK.
Which set of rates, thresholds and allowances to apply.

Your net worth, and how much of it is tax you have not paid yet
What you own less what you owe, after the tax that has not been paid yet
£517,879.00
£604,000.00 on the usual arithmetic, less £86,121.00 of tax already owed on it.
Three pots of £240,000, £45,000 and £60,000 are not the same money
Every net worth calculator adds a pension balance to an ISA balance and prints one number. They are not the same number. A pension has income tax attached to 75.00% of it; an unwrapped account has capital gains tax attached to its gain; an ISA has neither. Here is the same table with the tax shown against the row it belongs to.
| Where it is | Value | Tax on the way out | What it is worth to you |
|---|---|---|---|
| Cash and savingsNone on the capital. The interest is taxable income. | £12,000.00 | £0.00 | £12,000.00 |
| ISAsNone. Worth exactly its balance. | £45,000.00 | £0.00 | £45,000.00 |
| Investments outside a wrapperCapital gains tax on the gain, not on the value. | £60,000.00 | £3,600.00 | £56,400.00 |
| Defined contribution pensionsPart tax free, the rest taxable income on the way out. | £240,000.00 | £82,521.00 | £157,479.00 |
| Main homeNormally none — private residence relief on your only home. | £420,000.00 | £0.00 | £420,000.00 |
| Other assetsNot priced here. See the note below. | £15,000.00 | £0.00 | £15,000.00 |
| Total assets | £792,000.00 | £86,121.00 | £705,879.00 |
The pension figure is the tax if the whole taxable part came out in one tax year. That is the most expensive way to take it, and it is shown because it is the honest upper bound on tax already owed rather than because it is what anyone would do. Taken over more years, each year gets its own personal allowance and its own basic-rate band, and the total falls. The pension drawdown calculator works out what a particular withdrawal costs over a term.
The pension, in two halves
| Pot value | £240,000.00 |
|---|---|
| Tax free at 25.00% | £60,000.00 |
| Taxable as income whenever it is drawn | £180,000.00 |
| Income tax if all of that were drawn in one year, on top of £55,000 | £82,521.00 |
The first pound above the tax-free cash is charged at 40.00%, measured on your other income. The average rate across the whole withdrawal is higher than that, because a withdrawal that large climbs through the bands and can taper the personal allowance away on the way. Both figures come out of the same engine as the income tax calculator, and neither is a rate typed into this page.
The gain inside the unwrapped account
| Unrealised gain | £18,000.00 |
|---|---|
| Annual exempt amount used | £3,000.00 |
| Chargeable gain | £15,000.00 |
| Higher rate at 24.00% | £3,600.00 |
| Capital gains tax | £3,600.00 |
One annual exempt amount, used once. The exemption is annual, not per disposal, and this is a single calculation that deducts a full one — so it assumes you have made no other gains this tax year and that the whole account is sold in one of them. Sell over several tax years and there is a fresh exemption each time; sell alongside other gains and this figure is too low. The capital gains tax calculator takes the exemption as an input for exactly that reason.
What you owe
| Mortgage on the main home | £180,000.00 |
|---|---|
| Other debts | £8,000.00 |
| Total liabilities | £188,000.00 |
| Net worth, before the tax above | £604,000.00 |
The same total, on death
Inheritance tax is charged on the estate, and the estate is roughly this total — £604,000.00 here. It is a different question from the one above, because nothing is sold and no income is drawn: the pension income tax and the capital gains tax on this page are the cost of using the money, and this is the cost of leaving it.
| Estate | £604,000.00 |
|---|---|
| Nil-rate band | £325,000.00 |
| Residence nil-rate band | £175,000.00 |
| Taxable estate | £104,000.00 |
| Inheritance tax at 40.00% | £41,600.00 |
The next thing that changes for this estate is residence nil-rate band taper, which is £1,396,000.00 of estate away. That distance is measured in estate value, which is the number you typed — unlike the income thresholds elsewhere on this site, which the engine reports in taxable income and which have to be converted before they mean anything.
On your figures, the next pound of estate costs 40.00%.
Why the rate on the next pound is not one rate
| Estate | Rate on the next pound |
|---|---|
| £324,999 | 0.00% |
| £500,001 | 40.00% |
| £2,000,001inside the residence nil-rate band taper | 60.00% |
| £2,350,001 | 40.00% |
The column is not monotonic, and that is the finding. Above £2,000,000 each extra pound of estate is taxed and costs £0.50 of residence nil-rate band, so it exposes more than itself and the rate on that pound comes out well above the 40.00% headline. Once the band has gone there is nothing further to lose and the rate drops back. No government publication contains the higher figure, because it is not a rate — it is two rules meeting, which is why every number in the column is measured off the engine rather than written down.
This page models an estate and nothing else. Gifts made in the last seven years, a predeceased spouse’s unused bands, a charitable legacy and the reduced rate that comes with it are the inheritance tax calculator.
What the inheritance tax engine deliberately does not model
These are attached to every result the engine returns, and they are listed here in full rather than summarised, because each of them changes the answer rather than blurring it. The direction of the error is stated in each one, which is the part that tells you whether to stop reading and take advice.
- Business and agricultural property relief. Qualifying business and farm assets are relieved at 100% or 50%, capped from 6 April 2026 at a combined £1 million allowance per estate. Neither the reliefs nor the allowance is modelled, so an estate holding qualifying property is over-taxed here. The reliefs also do not reduce the estate value used for the residence nil-rate band taper, so the interaction is not a simple scaling.
- Trusts and settled property. No relevant property regime, ten-year anniversary charge, exit charge or qualifying interest in possession. Because a gift into trust is a chargeable lifetime transfer rather than a potentially exempt transfer, this also means the fourteen-year cumulation rule cannot arise, which is what makes the simple seven-year cumulation used here correct for the estates that are modelled.
- Long-term residence, excluded property and the capped spouse exemption. From 6 April 2025 liability turns on long-term UK residence rather than domicile. This engine assumes the whole estate is within charge and that the spouse exemption is unlimited. It does not model excluded property, nor the capped spouse exemption that applies where the surviving spouse is not long-term UK resident and no election is made — an estate in that position is under-taxed here.
- Quick succession relief. IHTA 1984 s.141 reduces the tax where the deceased themselves inherited within five years of their own death. Not modelled, so an estate entitled to it is over-taxed here.
- Grossing up and estate components. The reduced charity rate is computed for a single general component — the free estate. Survivorship and settled-property components, elections to merge them, and the grossing up of tax-free legacies out of a partly exempt residue are not modelled. HMRC’s own example (IHTM45030) shows the 10% test flipping on the grossing up alone, so a will with tax-free legacies and an exempt residue needs professional calculation rather than this one.
- Small gifts, wedding gifts and normal expenditure out of income. The £250 small-gift exemption is per recipient per tax year and is lost entirely if another exemption is used on the same person; wedding gifts depend on the donor’s relationship to the couple; normal expenditure out of income depends on a pattern of giving. None can be derived from a gift’s value and date alone. Pass the covered amount as the gift’s otherExemptAmount and it is deducted before the annual exemption, which is modelled in full.
- Gifts with reservation, the downsizing addition, instalments and interest. A gift the donor still benefits from stays in the estate; the downsizing addition preserves residence nil-rate band for someone who sold or downsized their home. Neither is modelled, and nor are the instalment option or interest on late-paid tax. The first two under-state and over-state the bill respectively.
Four things this page does not know
- What is in “other assets”. A second property carries capital gains tax at the residential rates and a business may carry none at all through business property relief — neither is priced here, and they are wrong in opposite directions. Anything in that box is treated as worth its value and taxed at nothing.
- A defined benefit pension. A final salary or career average pension is an income promise, not a pot, and has no balance to put in a net worth total. Leaving it out understates what you have; putting a transfer value in overstates it, because a transfer value is a price for giving the promise up.
- When any of this happens. Every tax figure here is at 2026/27 rates on today’s balances. Nothing is projected forward, no growth is assumed, and no allowance is indexed — which is why there is no term box and no growth box anywhere on this page.
- Anything about whether to act. The page prices what is already owed. It does not say where to hold money, when to draw a pension or what to do about an estate above the nil-rate band, and the arithmetic above is not an argument for any of those.
Worked example: a pension, a gain and an estate above the nil-rate band
Priya is 54, in 2026/27, and paying income tax in England on £62,000 a year. She owns £968,000.00 and owes £125,000.00, so every net worth calculator she can find tells her she is worth £843,000.00.
- £60,000.00 of that is in ISAs, and is worth exactly that. Nothing inside an ISA is taxed on the way out, whatever it grows to. The same is true of the £8,000.00 of cash: the capital is hers, though the interest on it is taxable income, which is where the savings interest calculator picks the story up.
- £310,000.00 is in a pension, and £232,500.00 of that is taxable income whenever she takes it. 25.00% — £77,500.00 — comes out free of tax. Drawn on top of her £62,000 in a single tax year, the rest costs £106,496.00 in income tax. That is the worst case rather than a plan: taken over more years it costs less, because each year brings a fresh personal allowance and a fresh basic-rate band.
- The £90,000.00 outside a wrapper carries a £35,000.00 gain. One annual exempt amount of £3,000.00 comes off, and the rest is charged on top of her taxable income: £7,680.00 of capital gains tax. Note what is taxed — the gain, not the £90,000.00.
- So the £843,000.00 is really £728,824.00. £114,176.00 of it is tax she has not paid yet. Nothing has gone wrong and nothing has been lost; the money was never hers to that extent, and a total that says otherwise is adding a pension balance to an ISA balance as though they were the same thing.
- On death the same estate carries £137,200.00 of inheritance tax. The nil-rate band covers £325,000.00 and — because her home passes to her children — the residence nil-rate band covers £175,000.00 more. The rest is charged at 40.00%. This is a different question from the one above: the tax in steps 2 and 3 is the price of using the money, and this is the price of leaving it.
| Figure | Amount |
|---|---|
| Assets | £968,000.00 |
| Liabilities | £125,000.00 |
| Net worth, as usually calculated | £843,000.00 |
| Income tax owed on the pension | £106,496.00 |
| Capital gains tax owed on the unwrapped gain | £7,680.00 |
| Net worth after the tax already owed | £728,824.00 |
| Inheritance tax on the same estate | £137,200.00 |
Methodology: which assets carry tax, and how much
The arithmetic, in full
- Net worth is assets less liabilities, and nothing about that step is clever. Both totals are sums of the boxes above them, and the result is shown even when it is negative, because a negative net worth is a real position rather than an error.
- The pension is split at 25.00%. That share comes out free of income tax; the rest is taxable income whenever it is drawn. The tax on it is worked out by running the income tax engine twice — once on your other income, once on your other income plus the taxable share — and taking the difference. That is the only reading that captures the personal allowance moving and tapering, which a flat marginal rate would miss.
- The unwrapped account is taxed on its gain, not its value. The gain is stacked on top of your taxable income to decide which capital gains rate it meets, after one annual exempt amount. A gain larger than the account holding it is capped and the capping is reported.
- The estate is the net worth, floored at nil. It carries the nil-rate band of £325,000.00, plus the residence nil-rate band of up to £175,000.00 where a home passes to direct descendants, and what is left is charged at 40.00%. Above £2,000,000 the residence band is withdrawn by £1 for every £2 of estate.

What has been verified, and what has not
The rates, thresholds and allowances used here were checked against gov.uk on 12 August 2026, figure by figure. That check covers the published figures only. It does not verify any result this page produces, and no named person has signed the check off yet. Treat the output as arithmetic you can follow — every figure it is made of is on the page for that reason — and not as advice about what to hold, when to draw it or what to do about an estate above the nil-rate band.
What this calculator does not do
- It does not project anything forward. There is no growth rate, no term and no future balance on this page. Every figure is today’s balance at 2026/27 rates, so nothing here is a forecast and none of it is presented as one. For growth, use the investment calculator.
- It does not price a second property or a business. Both sit in “other assets” and are treated as worth their value with no tax attached. A second property carries capital gains tax at the residential rates, which makes that understated; a qualifying business may attract business property relief against inheritance tax, which makes it overstated. They are wrong in opposite directions, which is why neither is guessed at.
- It does not model a defined benefit pension. A final salary or career average pension is an income promise rather than a pot, and has no balance that belongs in a net worth total.
- It does not model gifts, trusts or a predeceased spouse’s bands. The inheritance tax panel here is an estate and nothing else. The engine’s own list of what it does not model — business and agricultural property relief, trusts, the residence-based regime, quick succession relief and the rest — is printed in full on the page, with the direction of each error stated.

Net worth questions
- How do I work out my net worth?
Add up everything you own — cash, ISAs, investments, pensions, your home and anything else of value — and subtract everything you owe, including the mortgage. The answer can be negative, and often is for anyone early in a mortgage. That is the arithmetic every net worth calculator does. The part most of them leave out is that some of what you own has tax attached to it and some does not, so the total mixes money you can spend with money you cannot.
- Should a pension count towards net worth?
Yes, but not at its balance. 25.00% of a defined contribution pot comes out free of income tax and the rest is taxable income at whatever rate applies when it is drawn, so a pension is worth its balance less that tax. Adding a pension balance to an ISA balance treats two different amounts of money as the same. This calculator shows both figures and the gap between them.
- Does my house count towards net worth?
Yes, at what it would sell for, with the mortgage counted as a liability against it. Selling your only or main home is normally free of capital gains tax through private residence relief, so no tax is charged on that row here. It does count in full towards your estate for inheritance tax, which is a different question and is answered separately on this page.
- What is a good net worth for my age?
This calculator does not answer that and no calculator honestly can. A comparison against an average tells you about a population, not about whether your own position works: two people with identical totals can be in completely different situations depending on how much of it is in a pension they cannot touch for a decade, how secure the income behind it is, and what it is meant to pay for. What is on this page instead is the composition of your own total and the tax attached to each part of it.
- Is my net worth taxed?
There is no wealth tax in the UK, so the total itself is never taxed. What is taxed is money coming out of particular places: income tax on a pension withdrawal beyond the tax-free share, capital gains tax on a gain when an investment is sold, and inheritance tax on an estate above the nil-rate bands. All three are priced on this page, on the balances you entered.
- How much can I leave without paying inheritance tax?
The nil-rate band is £325,000, and where a home passes to children or grandchildren the residence nil-rate band adds up to £175,000 on top. A surviving spouse or civil partner can also inherit the unused percentage of both bands from the first death, which is why a couple's position is often roughly double an individual's. Everything above the bands is charged at 40.00%.
- Why does the rate on the next pound of estate rise above £2,000,000?
Because an extra pound of estate up there does two things at once. It is charged at the death rate of 40.00%, and it also withdraws £1 of residence nil-rate band for every £2 of estate, which exposes £0.50 more to the same rate. The result is 60.00% on that pound, and it applies until the residence band has gone entirely, after which the rate falls back. No government table publishes that figure because it is not a rate — it is two rules meeting — so this page measures it off the engine at four estate values rather than typing it into the copy.
- Do I include my student loan as a debt?
This calculator deliberately does not have a box for one. A UK student loan is repaid as a percentage of income above a threshold and written off after a fixed period, so it behaves like a graduate contribution rather than a debt: the balance is not what you will repay, and subtracting it from your assets misstates both sides. If you want it in your own total, put it in "other debts" knowing that the figure is not comparable with a mortgage balance.
- Does this include my partner’s money?
Only if you enter it. Assets are owned individually in the UK, income tax is individual, and inheritance tax is charged on each estate separately with transfers between spouses and civil partners exempt. A joint figure is useful for a household budget and is the wrong basis for every tax calculation on this page, so enter your own share, or run it twice.
