Assumptions & Limitations

What the calculation assumes

  • Every value you enter is treated as an exact, known amount.
  • Rates and contributions are assumed to stay constant for the whole period unless the form asks for them separately.
  • Results use standard financial formulas and ignore fees, penalties and promotional terms that are not entered above.
  • Inflation, tax changes and market volatility are not modelled unless a field for them is provided.
  • Amounts are unit-agnostic: results are returned in the same currency you enter.

What it does not cover

  • Portfolio Allocation Tool produces estimates for education and planning, not a quote, offer or professional advice.
  • Real-world outcomes differ when fees, taxes, rounding rules or provider-specific terms apply.
  • Local regulations and tax rules vary by country and change over time; verify current rules for your jurisdiction.
  • Figures are only as accurate as the inputs you supply — check them before acting on the result.
  • For decisions with lasting financial impact, confirm the numbers with a qualified professional.

Frequently Asked Questions

Over time, higher-performing asset classes grow faster and represent a larger percentage of your holdings, exposing you to unintended market volatility. Periodic rebalancing trims outperforming assets to buy underperforming ones, enforcing discipline and restoring intended risk.

Strategic asset allocation establishes long-term target asset mixes based on your risk tolerance and retirement horizon. Tactical asset allocation allows temporary short-term deviations to capitalize on specific macroeconomic market conditions or valuation disparities.

Holding assets with low or negative correlation (such as treasuries and domestic equities) ensures that when one asset class suffers a downturn, another stabilizes or appreciates, dampening portfolio drawdown without proportionally reducing expected return.

Selling appreciated assets in a taxable brokerage account triggers taxable capital gains. To minimize tax drag, consider rebalancing using new cash inflows or directing dividend payouts into underweight asset classes rather than selling winners.
