Beta Calculator

Measure systematic risk by calculating how assets move relative to the market benchmark (SPY).

What is Beta?

Beta (β) measures an asset's systematic risk — how much it moves relative to the overall market. A beta of 1 means the asset moves with the market.

Beta > 1 indicates higher volatility than the market, while beta < 1 suggests lower volatility. Negative beta means inverse correlation.

The Formula

β = Cov(Rₐ, Rₘ) / Var(Rₘ)
Rₐ : Asset Returns
Rₘ : Market Returns
Cov : Covariance
Var : Variance
