Inputs

Provide the following 4 values to run the Portfolio Volatility Calculator:

  • Stock Allocation (%) [number] (required)
  • Bond Allocation (%) [number] (required)
  • Stock Volatility (%) [number] — default 15
  • Bond Volatility (%) [number] — default 5

What it calculates

This tool returns:

  • Portfolio Volatility (%) — primary result
  • Risk Level
  • Est. Max Drawdown (%)

Worked example

For the sample inputs below:

  • Stock Allocation (%): 5
  • Bond Allocation (%): 5
  • Stock Volatility (%): 15
  • Bond Volatility (%): 5

the Portfolio Volatility Calculator produces:

  • Portfolio Volatility: 0.79%
  • Risk Level: Conservative
  • Est. Max Drawdown: 1.58%

How it works

The result is derived through the following steps:

  1. stockWeight = stockPercent / 100
  2. bondWeight = bondPercent / 100
  3. portfolioVolatility = sqrt(pow(stockWeight * stockVolatility, 2) + pow(bondWeight * bondVolatility, 2))
  4. riskLevel = portfolioVolatility > 12 ? 'Aggressive' : portfolioVolatility > 8 ? 'Moderate' : 'Conservative'
