About the Coefficient of Variation Calculator

The coefficient of variation (CV) expresses standard deviation as a percentage of the mean, making it possible to compare the relative variability of datasets with different units or vastly different scales.

Formula: CV = (Standard Deviation ÷ Mean) × 100

A lower CV indicates more consistent data relative to its average. CV is widely used in finance to compare investment risk-to-return ratios and in quality control to compare process consistency.
