Enter the full value of your home, not your equity - the mortgage is listed as a liability below, so entering equity as well would subtract it twice.

Asset Breakdown
How this calculator works
One subtraction, four buckets, and a handful of edge cases worth knowing about before you trust the answer.
The formula
Net worth = ΣA − ΣL Bucket(c) = Σ{ A : category(A) = c } Liabilities bar = min(100, ΣL ÷ ΣA × 100)- ΣA
- Total assets — every value in the assets table added together. Blank or unparseable fields count as zero; negative numbers are accepted and subtract from the total.
- ΣL
- Total liabilities — every value in the liabilities table added together, on the same rules. Liabilities have no category and no interest rate.
- c
- The asset category chosen on each row: Cash & savings, Investments & pensions, Property or Other. Each asset belongs to exactly one, so the four buckets always add back to ΣA. New rows default to Other.
- min
- Caps the liabilities bar at full width, so owing the same as you own and owing three times as much look identical. If ΣA is not above zero the ratio is skipped and the bar is drawn full width.
No rounding is applied to the arithmetic itself — the totals are held at full floating-point precision and only the display is rounded, to two decimal places (zero for yen), in whichever currency your iBudget profile or browser locale reports. Net worth of exactly zero is treated as positive and shown in the success colour.
There is one subtraction on this page, and everything else on the screen is a way of looking at it. The calculator sums the value of every row in the assets table, sums the value of every row in the liabilities table, and subtracts the second from the first. No row is weighted, discounted or adjusted for risk, and liabilities carry no interest rate — a revolving credit card balance and an interest-free loan from a parent do identical damage to the total.
Each value field is read with parseFloat, and anything blank or unparseable becomes zero. That matters in two directions. A row you meant to fill in but left empty silently lowers your total rather than warning you, and because the input hides zeros, a row genuinely worth zero looks like an empty box. Negative numbers are accepted as typed: entering −2,000 as an asset works and reduces your total, which is one way to record an overdrawn account, though the cleaner approach is to list it as a liability.
The four asset buckets — Cash & savings, Investments & pensions, Property, Other — come from the dropdown on each row, not from your label. Earlier versions of this tool guessed the category by keyword-matching the name you typed, which double-counted rows that hit two keyword lists and dropped everything else; an explicit choice means each asset lands in exactly one bucket, the four buckets always add back to your total, and none of them can be wrong because you named something creatively. New rows default to Other.
The two visual bars are ratios rather than a second calculation. The assets bar is always drawn full width, and the liabilities bar is your total liabilities divided by your total assets, capped at 100%. So a household owing exactly as much as it owns and a household owing three times as much both show a full red bar. The asset breakdown strip underneath divides each bucket by total assets and only appears once total assets are above zero. Everything recomputes on every keystroke, in your browser, and nothing is saved or sent anywhere.
A worked example
One US household, run end to end. A UK household would follow identical steps in pounds — nothing in the arithmetic changes with the currency.
Two earners in their late thirties, one house, one car on finance
Worked example- Checking account (Cash & savings)
- $4,200
- High-yield savings (Cash & savings)
- $18,500
- 401(k) (Investments & pensions)
- $96,000
- Roth IRA (Investments & pensions)
- $31,000
- Taxable brokerage (Investments & pensions)
- $12,300
- Home, full market value (Property)
- $415,000
- Car, resale value (Other)
- $17,000
- Total assets (ΣA)
- $594,000
- Mortgage balance
- $327,400
- Auto loan
- $11,800
- Student loans
- $23,600
- Credit cards
- $6,000
- Total liabilities (ΣL)
- $368,800
- Liabilities bar = 368,800 ÷ 594,000
- 62%
The buckets come out as $22,700 cash, $139,300 investments, $415,000 property and $17,000 other — which add back to $594,000, as they always must. The instructive move is to strip out the house: take away the $415,000 property row and the $327,400 mortgage and you are left with $137,600. That is the household's net worth excluding the roof, against $87,600 of home equity, and it is the figure that tells you what would actually be available if something went wrong. Note also that the screen would print $225,200.00 — the display carries two decimal places.
How to read your result
What the number is telling you, what it is hiding, and what to do about each.
Look at the sign first, then the composition, then the trend. A positive number is the low bar, not the goal, and negative is normal at the start of a working life. The composition is where the useful information is: a net worth of 225,000 made up of 87,000 of home equity and 138,000 of cash and investments is a very different financial position from the same 225,000 sitting entirely in a house, even though this calculator prints the same figure for both. The four buckets exist so you can see which one you are.
The quick test is to subtract your home value and your mortgage from the result and see what is left. That is your net worth excluding the roof over your head — the part you could actually spend without moving — and for a lot of homeowners it is a fraction of the headline. It is also the number that explains why people who look wealthy on paper are still one boiler failure away from a credit card balance. The Federal Reserve found that 30% of US adults could not cover three months of expenses by any means at all, including borrowing and selling assets, which is a liquidity problem rather than a net worth problem.
Then compare the liabilities bar to your income rather than to your assets. Mortgage debt against a rising asset is a different animal from card debt against a depreciating one, and the calculator cannot tell them apart. If the bar is long and most of it is unsecured, the highest-return move available to you is almost always paying that down rather than adding to savings — no ordinary asset returns what a credit card charges. If the bar is long and it is nearly all mortgage, you are in a normal position for a recent buyer in every market on this list.
Finally, treat one reading as noise. The point of this calculation is the second one. Two figures three months apart tell you whether your income is building anything, which is the question a single snapshot cannot answer.
Some scale for the two halves of the calculation. These are official statistics rather than targets, and each measures something slightly different from what you have just typed — read the notes before you compare yourself to any of them.

US household debt as a share of net disposable income
2024. The UK sits at 130.8%, Canada 181.1% and Australia 209.6%. Mostly mortgages and consumer credit, measured against income rather than against assets — a useful counterweight to the liabilities bar.

Average total debt per UK household, mortgage included
May 2026. This is total UK personal debt divided by the number of households, not the debt of a typical borrower, and £59,030 of it is secured on property. Treat it as a headline rather than a target.

Average UK house price
May 2026, up 2.7% on the year — a provisional estimate. England averaged £292,000, Wales £215,000 and Scotland £196,000, so a national figure is a weak comparator for any individual property row.
The other half of the picture is how fast the number can move. Net worth grows from three sources: what you save out of income, what your investments earn, and what happens to house prices. Only the first is under your control, and in the Anglosphere it is a thin margin.
5.7%
US household net saving rate
2024, on the OECD's net measure — after depreciation, as a share of net disposable income. The UK managed 4.7% and Canada 5.1%, against 16.3% in Sweden. Not comparable with the gross saving ratios national statistics agencies publish.
30%

By any means at all, including borrowing and selling assets — which is why a healthy net worth and a fragile household are perfectly compatible. Survey fielded October 2025, expressed as a share of all adults.

Combined net worth of Canadian households
Q1 2026, up 1.3% on the quarter. An aggregate for the entire household sector, not a per-household average — wealth is heavily skewed, so dividing it by the number of households produces a meaningless figure.
What this calculator does not account for
Every simplification the arithmetic makes, stated plainly, so you know which direction the answer is wrong in.
No liquidity, no risk, no time horizon
Every pound and dollar counts the same regardless of how quickly you could get at it. A pension you cannot touch for twenty years, a house that takes four months to sell, and cash in your current account are treated as identical. The four asset buckets are the only hint of this distinction, and they are labels on a chart rather than an input to the maths.
No tax of any kind
Assets are entered gross. Capital gains tax on investments and second properties, income tax on pension withdrawals, inheritance or estate tax, and any exit or surrender charges are all invisible. For a household whose wealth is mostly in taxable investments and retirement accounts, the after-tax figure can be materially lower than the one displayed.
No interest rates on the debts
Liabilities are just balances. The calculator has no field for an APR, so it cannot tell an interest-free balance transfer from a UK credit card charging the June 2026 average of 24.69% on balances that bear interest, or from a fixed-rate mortgage. Two households with identical net worth can be on completely different trajectories purely because of the rate on what they owe — which is what a debt payoff calculator, with a rate field, is for.
No inflation, and no projection
This is a snapshot in today's money with no forward-looking element whatsoever. It does not grow your investments, amortise your mortgage, depreciate your car or adjust anything for inflation. Comparing a figure from 2026 with one from 2021 without adjusting for price rises will overstate real progress.
Your valuations are unchecked inputs
The house price, the car value and any jewellery, watches or collectables are worth exactly what you typed, and the result inherits every ounce of optimism in those numbers. Nothing warns you when a single row dominates the total. Because there is no confidence range, a house valued 10% high moves the answer by more than a year of most people's saving.
No ratios beyond the raw total
It does not compute a debt-to-asset ratio, a liquid net worth, a net worth to income multiple, or where you sit in any age or country distribution. There is no historical tracking either — reopening the page reloads the seeded example figures, so it cannot show you a trend line even though the trend is the reason to do this.
Currency is formatting, not conversion
Amounts are formatted to your detected currency, to two decimal places in all but yen, but nothing is converted. If you hold a US brokerage account, a UK pension and a euro savings account, you must convert them to one currency before entering them, and record the exchange rate you used so the next quarter's comparison is honest.
It starts pre-filled with an example
The tool loads with a sample balance sheet — 405,000 of assets against 238,000 of liabilities, for a net worth of 167,000 — so that the chart has something to draw. Those are placeholder figures, not a benchmark and not a default household. Overwrite every row before reading anything into the result, and note that the last remaining row in each table cannot be deleted.
Frequently asked questions
What is net worth, and how is it calculated here?
Net worth is everything you own minus everything you owe. This calculator adds up every row in the assets table, adds up every row in the liabilities table, and subtracts the second total from the first. There is no weighting, no discounting and no adjustment for how easily an asset could be sold — a pound of home equity and a pound in your current account count exactly the same.
Do I enter my home's full value or just my equity?
The full market value, and then the outstanding mortgage as a separate liability. The calculator has no idea that the two rows are related, so if you enter equity as the asset and still list the mortgage below, the mortgage is subtracted twice and your net worth comes out roughly one mortgage too low. This is the single most common way people get a wrong answer from a net worth calculation.
Should I include my pension, 401(k) or ISA?
Yes — put the current balance in and tag it as Investments & pensions. For most households in their forties and beyond, retirement accounts are the largest financial asset after the house, and leaving them out makes the picture look far worse than it is. Use the value on your latest statement, not a projection of what it might be worth at retirement.
Is a negative net worth bad?
It is very common and, on its own, tells you little. A newly qualified professional with student debt and a recent mortgage will often be deeply negative and in a perfectly sound position, because the debt bought an asset — an education or a house — that the calculator either cannot value or values conservatively. What matters is the direction of travel: run the same numbers in three months and see whether the figure moved up.
What is a good net worth for my age?
There is no threshold that makes an answer right or wrong, and the age-based rules of thumb you will see quoted (one times income by 30, two times by 35) come from advice columns rather than from any statistical source. Cross-country figures give some sense of scale — the OECD put US net financial wealth at the equivalent of USD 322,511 per person in 2024 against USD 92,884 in the UK — but those are per person, PPP-converted and exclude housing entirely. Compare yourself with your own figure from last quarter instead.
Should I include my car?
Include it at what you could actually sell it for today, not what you paid, and list any outstanding finance as a liability. Cars are the clearest example of an asset that flatters a net worth statement: the value falls every month whether you look at it or not, and a car on PCP or a long loan is frequently worth less than the balance owed on it. Tag it as Other so it does not inflate your investment total.
How do I value a house I have not sold?
Take a recent sale price for a comparable property on your street, or an online estimate, and then knock something off. A useful discipline is to enter the number you would accept for a quick sale rather than the number you hope for, because that is closer to what the asset is worth if you ever need it. If a 10% swing in that one figure changes how you feel about the result, the honest conclusion is that your net worth is mostly a house price forecast.
Does the calculator account for tax on selling assets?
No. Every asset is counted at its gross value, so a general investment account showing a large gain, a rental property facing capital gains tax, or a pension that will be taxed on the way out are all treated as if you could convert them to cash at full value tomorrow. Your after-tax net worth is lower than the number on the screen, sometimes by a great deal, and the gap is widest for people whose wealth sits mostly in taxable investments and pensions.
Should student loans go in as a liability?
Enter the outstanding balance, but read it in context. A US federal or private student loan is a conventional debt and belongs in the table without qualification. A UK income-contingent student loan behaves more like a graduate tax — repayments depend on income, the balance is written off after a fixed period, and many borrowers never repay it in full — so including the whole balance can make an otherwise healthy position look alarming. The calculator cannot tell the difference, so make the judgement yourself.
Why is the result showing the wrong currency, or showing cents?
The calculator reads a currency from your saved iBudget preference or, failing that, your browser locale, and formats every figure with it — to two decimal places in every currency except yen, which is formatted whole. So a net worth of 225,200 displays as 225,200.00. It never converts anything: switching currency changes the symbol and the formatting, not the numbers you typed. If you hold accounts in more than one currency, convert them to a single currency yourself before entering them.
How often should I recalculate?
Quarterly is enough for most households, and monthly is the most that is useful. Net worth moves slowly and is dominated by asset prices you do not control, so checking it weekly mostly measures the stock market's mood. What a quarterly rhythm does give you is a series of four or five points a year, which is the minimum needed to tell a trend from a wobble.
Should a couple calculate this jointly or separately?
Do both if you can, and at least once. A joint figure is the one that matters for household decisions such as moving, retiring or taking on debt. Individual figures matter too: the Nuffield Foundation's Fair Shares study found pension sharing features in only about 10% of divorces in England and Wales, despite pensions often being a couple's second-largest asset — which is a lot easier to notice when you have each written your own balance sheet down.
