These figures are estimates from long-run developed-market asset-class assumptions, not your portfolio's actual history. Return and severe-loss are weighted averages of the asset classes; volatility applies a rough diversification adjustment. A real portfolio's worst drawdown depends on how assets move together in a crisis — often worse than a simple weighted average suggests. Treat this as a starting point, not a forecast.

Common questions

What is asset allocation, and why does it matter?+

Asset allocation is how you divide your investments among broad categories such as stocks and bonds. It is widely regarded as the single biggest driver of a portfolio's risk and long-run return - far more than picking individual investments. A mix weighted toward stocks offers higher expected growth with bigger swings; a mix weighted toward bonds is steadier but grows more slowly. Getting the balance right for your situation matters more than almost any other investing decision.

How does age affect the right stock/bond mix?+

A common starting point is to hold a higher share of stocks when you are young and have decades to recover from downturns, then gradually shift toward bonds as you approach the time you will need the money. One old rule of thumb subtracts your age from a fixed number to get your stock percentage, but it is only a guide. Your real answer depends on your time horizon and how much volatility you can tolerate without panic-selling.

What is risk tolerance, and how do I judge mine?+

Risk tolerance is your genuine ability to stay invested through a large drop without selling at the worst moment. It has two parts: your financial capacity to absorb losses, and your emotional comfort with seeing your balance fall. Be honest about the emotional side - an allocation you will abandon in a crash is worse than a more conservative one you can hold. This tool suggests a mix, but your behaviour in a downturn is the real test.

Is the suggested allocation personalised advice?+

No. It is an educational estimate based on general guidelines and the age and risk inputs you provide. It cannot see your full financial picture, goals, or tax situation, so treat it as a starting point for your own thinking rather than a recommendation. For an allocation tailored to your circumstances, consult a licensed financial adviser.
