What net worth measures
Net worth is the value of everything a household owns, minus everything it owes: total assets — a home, vehicles, RRSPs, TFSAs, non-registered investments, business equity, and so on — minus total debt, such as a mortgage, a line of credit, student loans or credit card balances. Unlike income, which measures a flow of money over a period (a year, typically), net worth is a snapshot: the value of everything owned and owed on one specific date, regardless of how that value built up or how quickly.
The net worth figures on this site come from Statistics Canada's Survey of Financial Security, which measures net worth at the family level rather than the individual level. A couple's net worth in this data is their combined net worth, not each partner's separate share of it, and the survey does not attempt to attribute the couple's assets and debts to one partner or the other. That is a different unit of measurement than the income comparisons on this site, which are individual-level — a distinction covered in more depth in the guide to average income.
Because net worth is a snapshot rather than a flow, two families with identical annual income can show very different net worth simply because of when in their lives that snapshot was taken, what they have chosen to buy versus rent, and how long they have held whatever assets they hold. Income describes what came in over a year; net worth describes what has accumulated, or has not, by a single point in time.
Registered accounts count toward net worth at their current market value on the survey date, not at whatever amount was originally contributed or at whatever amount would actually land in the household's hands after tax if withdrawn. An RRSP balance, in particular, is recorded at its full face value even though a future withdrawal from that balance will be taxed as ordinary income, a point covered in detail in the guide to FIRE in Canada — the net worth figure and the after-tax value of that same account are not the same number.
Why the mean-median gap is wider for wealth than income
The gap between the average and the median is wider for net worth than for income, and by a considerable margin, because wealth concentrates far more heavily than income does. A relatively small number of families hold a very large share of total net worth in Canada — multi-property owners, business owners with substantial equity, long-tenured investors whose holdings have compounded for decades — and their fortunes pull the average upward without moving the median, the point at which half of families hold more and half hold less, nearly as much.
Income resets, in part, every year: a given year's paycheque does not automatically compound the way an investment portfolio or a home's value can. Net worth accumulates and compounds across decades, so small early differences in saving, investing or property ownership can widen into very large differences later, stretching the distance between a typical family's net worth and the average family's net worth further than any single year's income gap would suggest on its own.
This is also why net worth comparisons are more sensitive to how the data is sliced than income comparisons are. A national average net worth blends together households at every stage of the life-cycle and every level of housing-market exposure into a single number, and that number is disproportionately shaped by the wealthiest slice of that population in a way a median figure, by construction, resists.
The life-cycle curve
Net worth in this data follows a clear life-cycle shape. It starts low for young adults just beginning to earn and save, often close to zero or even negative once student debt is counted, climbs steadily through the working years as mortgages are paid down and retirement accounts grow, and typically peaks somewhere around the years just before retirement. This roughly mirrors the income life-cycle described in the income guide, but net worth peaks later and falls more gently after that peak, because a family's accumulated assets do not disappear the moment employment income stops the way a paycheque does.
What happens to net worth after that peak is less uniform than the climb toward it. Some families draw down savings and investments in retirement to fund living expenses, which lowers net worth over time as the drawdown outpaces investment growth; others hold onto a paid-off home and a modest, slowly drawn-down investment account well into their eighties, keeping net worth relatively stable because the home's value continues to shift with the local housing market independent of whatever spending decisions the household makes.
A family's position on this curve says as much about their stage of life as it does about their financial choices. Comparing a 30-year-old's net worth against a 60-year-old's net worth without accounting for where each sits on the same life-cycle curve risks attributing a difference to saving discipline or income when years of compounding, and years of mortgage repayment, explain a substantial share of the gap on their own.
Principal residence equity dominates the balance sheet
For a typical Canadian family, the single largest asset on the balance sheet is not a retirement account or an investment portfolio — it is the equity in their principal residence: the home's market value minus whatever remains on the mortgage. This is a large part of why net worth figures can vary so sharply by province independent of income: a family in a province with a high-priced housing market can hold substantially higher net worth than a family with a similar, or even higher, income in a province where homes are cheaper, simply because of how much their home has appreciated over the years they have owned it.
This also means net worth figures are sensitive to the timing of a home purchase and to local real estate cycles in a way income figures are not. A family that bought a home years before a period of rapid local price growth holds an asset that has appreciated well beyond anything their income alone would predict; a family that has not yet purchased, or that bought at a market peak, does not share in that same effect regardless of how comparable their income is to the first family's.
Because housing wealth is concentrated in a single, illiquid asset, it also behaves differently from financial wealth in a way that matters for interpreting the life-cycle curve above. A retired homeowner can show a large net worth on paper while holding comparatively little in accessible savings, since realizing the value in a principal residence generally means selling it or borrowing against it, not simply withdrawing from an account the way a TFSA or RRSP allows.
Debt is part of the calculation too
Net worth nets out debt, not just assets, and debt follows its own pattern across the life-cycle. Mortgage debt is typically highest earlier in the life-cycle and falls as the mortgage is paid down, all else being equal; other forms of debt — lines of credit, credit card balances, student loans, vehicle loans — vary more by individual circumstance than by any single age pattern. A family carrying a large mortgage against a valuable home can show a much smaller net worth than the home's sale price alone would suggest, because the outstanding loan balance is subtracted before the figure is reported.
A family whose debts exceed their assets records a negative net worth, which is possible at any age but is most common earlier in the life-cycle, before assets have had time to accumulate against debt already taken on — a recent graduate carrying student debt with few assets yet to offset it is a common example of how a negative figure arises without implying anything unusual about that person's situation.
Business equity adds a further wrinkle for self-employed households and small business owners, since the value of a privately held business is counted as an asset alongside the home, the investments and everything else, but that value is far harder to establish precisely than a bank balance or a publicly traded stock, and it is generally far less liquid — realizing it typically means selling the business itself, not making a withdrawal.
Net worth is not split by gender or education
The Survey of Financial Security reports net worth by province and age; it does not break the figure down by gender or by education level the way the census income data does. Changing a person's gender or education in this site's inputs changes their income comparison; it does not change the net worth comparison, because no such split exists in the underlying survey to draw on.
This is a genuine data limitation rather than a design choice made by this app. A family's net worth reported here is the same figure regardless of which partner's demographics are entered, which follows directly from net worth being measured at the family level in the first place rather than at the individual level the way income is — the survey was never designed to attribute a shared home, a shared mortgage or a shared investment account to one partner over the other.
A related limitation applies to city-level detail. Income comparisons on this site can narrow to a specific city where that data exists; net worth comparisons cannot, because the Survey of Financial Security does not publish net worth at the city level, only by province and nationally. A family in a specific city sees the same net worth comparison as the rest of their province, even though local housing costs within a single province can vary as much as housing costs do between provinces.
Each of these limitations traces back to the same root cause: the underlying survey was designed and published at the province-by-age level, and every comparison this site offers on net worth is built as faithfully as possible from exactly that level of detail, no finer and no coarser than what Statistics Canada actually released.
Net worth as a retirement-funding measure
Income and net worth answer different questions about the same household, and the difference matters most at the point of retirement. Income measures what continues to arrive each year; net worth measures what has already accumulated and can be drawn down or converted into income when employment earnings stop. A household with a modest income throughout its working years but decades of disciplined saving and a long-held, appreciated home can reach retirement with a substantial net worth despite never having had a high income at any single point along the way.
This is one reason the life-cycle curve for net worth matters beyond simple curiosity: the shape of that curve, and where a given household sits on it, says something about how much of a retirement's funding is already banked in accumulated assets versus how much still depends on income yet to arrive. A full treatment of drawing down that accumulated net worth in retirement, including the registered-account rules that govern how much of it a household actually keeps after tax, is covered separately.
The limits of the data above the 90th percentile
One further limitation is worth disclosing plainly, because it affects the upper end of the net worth range specifically. The published breakdown of net worth by quintile stops at the wealthiest fifth of families as a single combined group; there is no published breakpoint separating, say, the top 5% from the top 1% within that group. For any family this app places above roughly the 90th percentile, the reported figure is an estimate that extrapolates beyond the finest breakdown the underlying data actually provides, rather than a number read directly off a published threshold.
The practical effect is that precision narrows considerably at the very top of the net worth range shown on this site. A percentile in the middle of the distribution rests on a real, published breakpoint close by; a percentile above the 90th rests on a projection built outward from the same breakpoints, indicating scale at the top of the wealth range rather than the more precise ranking the middle of the distribution allows.
This limitation is disclosed here rather than smoothed over because the wealthiest households are exactly the group for whom the gap between a real breakpoint and an extrapolated estimate is largest in absolute dollar terms, even though the percentile scale itself runs from 1 to 99 the same way at every point along it, with no visual or numerical flag anywhere in the result distinguishing an extrapolated percentile from one anchored firmly to a published breakpoint.
