Risk tolerance, risk capacity and risk need: three different questions

"How much risk should I take?" is really three questions: how big a fall someone can sit through, how big a fall their finances can absorb, and how much return the goal requires. The three often give different answers.

Canadian figures after inflation, in CAD, unless noted. Updated October 2026.

Tolerance: the psychology

Risk tolerance is how far a portfolio can fall before its owner would sell. It's about behaviour, not arithmetic, and people tend to overestimate it until they live through a real crash. The most honest test is what someone actually did in 2008, 2020 or 2022.

History gives a sense of what each mix of stocks and bonds has felt like. From 1977 to 2025, after inflation, a portfolio of all stocks fell as much as 44% from its peak at the worst point. In its slowest recovery it took 77 months to get back to a previous high. Its worst calendar year was 2008, at about −27%. A 60/40 mix of stocks and bonds fell about 26% at worst.

Worst fall from a peak after inflation, 1977–2025, before fees. Global stocks (Ken French data, summary figures) and a Government of Canada bond estimate (Statistics Canada yields), rebalanced monthly.

Notice the left end. All bonds fell further after inflation (−32%) than mixes with 20% to 40% in stocks, because the high inflation of the late 1970s and early 1980s eroded bonds slowly. Every asset has a way to lose; tolerance is about which kind of loss someone can live with.

Capacity: the finances

Risk capacity asks a different question: would a fall actually change someone's life? It depends on the time until the money is needed, how stable the income is, whether there's an emergency fund, any high-interest debt, and pensions. A useful test is to imagine a 40% fall in the year the money is needed.

Human capital: a person as a bond or a stock

For young people, the biggest asset usually isn't the portfolio. It's future paycheques. Using Statistics Canada's median employment income by age (2024), the future earnings of a typical 25-year-old up to age 65 are worth about $1.37 million today, discounted at 3% a year after inflation (pre-tax, with no real wage growth). The median under-35 household holds about $50,700 in financial assets. On those numbers, future earnings are about 96% of total wealth.

Statistics Canada table 11-10-0239 (median employment income by age, 2024) and Survey of Financial Security 2023 (median financial assets, approximate). The discount rate is a judgement: at 2% the 25-year-old's figure is about $1.61 million, at 5% about $1.02 million.

The kind of job matters as much as the size. A stable job, such as in the public sector, pays like a bond. A volatile or market-linked one (commissions, start-ups, the oil patch) behaves more like a stock. As an illustration: for a 35-year-old with a bond-like job to hold 60% stocks across total wealth, including future earnings, the portfolio would need about 6.7 times its own value in stocks. That's impossible without borrowing, but it shows why steady earnings add capacity, and why a job tied to one industry can argue for owning less of that industry.

CPP and OAS: a bond floor

Government pensions add capacity later in life. Average CPP plus OAS pays about $19,450 a year, rising with inflation, for life. Valued like a bond at the real-return bond yield of 1.88% (October 26, 2026), with Statistics Canada life tables, that income is worth about $334,000 at 65. With maximum CPP it's about $464,000. These are per person and pre-tax.

Longevity cuts the other way. Life expectancy at 65 is about 21 years, 57% of 65-year-olds reach 85 and 15% reach 95. Retirement money is still long-horizon money.

Need: the goal's arithmetic

Risk need is the return the goal requires, given the savings and the time. Take an example in today's dollars: $50,000 saved, $1,000 added each month, and a $500,000 goal in 25 years. With no growth at all the plan reaches $350,000. Solving the standard future-value formula, the goal needs about 2.5% a year after inflation.

The interactive guide's forward assumptions put Canadian bonds at about 1.8% a year after inflation (from Government of Canada yields, September 2026) and stocks at about 4.7% (bonds plus a 3-point premium, with the Bank of Canada's 2% inflation target). At the bond figure alone, the plan ends near $452,000. So this goal needs some growth beyond bonds, but not a lot. These are assumptions, not forecasts, and real outcomes spread widely around them.

Need sets a floor, not a ceiling. When the mix that fits tolerance and capacity can't reach a goal on reasonable assumptions, the usual levers are saving more, allowing more time or adjusting the goal, rather than taking on risk that can't be held or afforded.

Putting the three together

A common textbook rule is: take the lower of tolerance and capacity, then check it against need. Going past tolerance risks selling near the bottom. Going past capacity risks a fall that derails the goal. Need then shows whether the resulting mix is enough, or whether the plan itself has to change.

The answer also differs by goal. Money for a house in three years and money for retirement in 25 years face different horizons, so the same person can reasonably get two different answers for two pots of money.
