Portfolio Alpha, Beta & Risk Calculator
Compile multiple statement dates or matched return data to estimate alpha, beta, R², standard deviation, and annualized return against a chosen benchmark.
Plain-language guide
How has my portfolio behaved relative to a benchmark?
How this estimate works
The calculator uses matched periodic portfolio and benchmark returns. Statement mode estimates cash-flow-adjusted holding-period returns from ending values; analytics use sample covariance and variance, CAPM-style alpha, squared correlation, and annualized sample standard deviation.
Important: This is an educational estimate, not individualized financial, investment, tax, legal, insurance, or business-valuation advice.
Common questions
- Which benchmark should I use?
- Choose a benchmark that reasonably reflects the portfolio's strategy and exposures. A poor match can make alpha, beta, and R² misleading.
- What does R² mean?
- R² estimates how much of the variation in the portfolio returns is statistically associated with variation in the selected benchmark over the uploaded period.
- Are uploaded statements stored?
- No. Supported files are read and calculated in your browser. Statement contents and calculated values are not sent to Simple Financial, FlexConnect, Microsoft Clarity, or another server.
