Understand investment risk and the cost of fees

Risk belongs beside the expected result

Time horizon and willingness and ability to tolerate losses affect an investment decision. Diversification spreads exposure, but it does not eliminate the possibility of a loss. Several funds can still own overlapping assets, so a long list of holdings is not proof of a diversified portfolio.

Our growth tool applies a constant return. Real markets do not deliver the same result each month, and the order of returns matters when money moves in or out. Test lower and negative assumptions instead of treating the default scenario as a likely outcome.

Separate the costs and the purchasing power

Look at recurring asset fees, fund expenses, account charges and transaction costs. Understand whether an advertised fee includes all of them. Small annual differences can accumulate because money paid in fees cannot continue growing in the account.

The tool reports nominal dollars and a separate inflation-adjusted balance. The latter describes purchasing power under your inflation assumption, not cash you can withdraw today. It excludes taxes, trading costs and withdrawals; it does not establish a safe withdrawal amount or tell you when to retire.
