Is Your House Part of Your Net Worth? Yes: Equity, Not Price
Yes, your house is part of your net worth: but only the equity. The number that counts is today's realistic value minus the outstanding mortgage. A £300,000 house with a £250,000 mortgage adds £50,000 to your net worth, not £300,000, and the price you paid for it years ago is not part of the sum at all.
This is how the official statistics do it too: the ONS counts net property wealth in its household figures, and for most British households it is the single largest entry, ahead even of pensions. It is the main reason median household wealth by age climbs so steeply: equity builds silently as the mortgage shrinks and prices move.
At a glance
- Does the house count?
- Yes: value minus mortgage (equity)
- What you paid
- Irrelevant: today's value is the number
- Renting?
- The home adds nothing: no equity exists
- Second homes & BTLs
- Count the same way, each net of its mortgage
Getting the value honestly
The equity sum is only as good as the value you feed it, and homeowners are reliably optimistic. Three honest options, in rising order of effort:
- Your area's index movement applied to what you paid. If you paid £220,000 in 2019, HM Land Registry's index for your area says what that money's house is worth now. Our house value calculator does this from your postcode, and the net worth calculator can pull the same estimate inline and re-run it monthly.
- Your home's own last recorded sale, restated. Stronger, because it starts from your actual house. The postcode lookup in the calculator offers this where the sale is on record.
- What similar homes on your street actually sold for recently. The strongest evidence short of a valuation; sold prices are public.
Whichever you use, resist rounding up. An inflated house value is the most common way a net worth figure flatters its owner, and it corrupts the only comparison that matters, which is your own figure over time.
The arguments for leaving it out
Some people track net worth without their home, and the logic deserves a fair hearing: you have to live somewhere, you cannot spend the kitchen, and selling to realise the equity means buying somewhere else at the same market's prices. All true. But the equity is still real: it shrinks your mortgage interest, it transfers when you move, it can be borrowed against, and it is inheritable. The better resolution is the same as with pensions: keep the full figure for wealth, and watch liquid net worth for what you could actually reach in a bad month.
What is not defensible is counting the house at its value while forgetting the mortgage. That single error produces most of the impressive-sounding net worth figures people quote.
Frequently asked questions
Does my house count if I have a mortgage?
Yes: the equity counts. Today's value minus the outstanding balance. Early in a repayment mortgage the equity can be small, and with a 95% loan it is nearly nothing, which is the honest picture.
I rent. Does my home count for anything?
No equity exists in a rented home, so it adds nothing, and this is the single biggest driver of the wealth gap between renting and owning households: the median renting household holds £900 of net financial wealth against £55,300 for outright owners, as the average savings figures show.
Do buy-to-lets and second homes count?
Yes, exactly the same way: each property at today's value minus its own mortgage. The ONS counts all net property wealth, not just the main home.
Should I subtract selling costs?
For a precise figure before an actual sale, yes: agent and legal fees take 1 to 2%. For routine tracking most people skip it; just be consistent from one check to the next.
