Formula & Mathematical Calculation

Calculation Method

  1. total: Object.values(allocs).reduce(function(a, b) { return a + b
  2. w: v ÷ 100
  3. diversScore: Math.min(10, ((1 - herfindahl) × 10 × (numAssets ÷ 6)).toFixed(1))
  4. riskWeight: allocs.stocks × 0.8 + allocs.crypto × 1.5 + allocs.realEstate × 0.5 + allocs.commodities × 0.6 + allocs.bonds × 0.2 + allocs.cash × 0

Calculation Example

A portfolio of 60% stocks, 30% bonds, and 10% cash totals 100%, so it calculates. Using the tool's built-in asset-class return assumptions (stocks 10%, bonds 4.5%, cash 2%), the estimated annual return is 0.60 × 10% + 0.30 × 4.5% + 0.10 × 2% = 7.55%, alongside a diversification score and a risk level for the mix.

Key Benefits

  • Checks that your allocations total 100% before it will calculate.
  • Estimates an annual return by weighting each class by the tool's built-in assumptions.
  • Scores diversification from how evenly the weight is spread across classes.
  • Reports a risk level for the overall mix so you can compare allocations.

How to Use this Calculator

  1. Enter each allocation
    Type the percentage held in stocks, bonds, real estate, cash, crypto, and commodities in the six allocation fields.
  2. Make the total 100%
    Adjust the percentages until they add up to 100%; the running total must reach 100% (within half a percent) or the tool will not calculate.
  3. Press Calculate
    The tool weights each class by its built-in expected return, sums the weighted returns, and derives a diversification score and risk level from the mix.
  4. Compare mixes
    Change the allocations to see how shifting weight between classes moves the estimated return, diversification score, and risk level.

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.
