Coefficient of Variation Calculator
Calculate the coefficient of variation (CV) from a mean and standard deviation to compare relative variability.
Formula: CV = (σ / μ) × 100
About Coefficient of Variation Calculator
Coefficient of Variation Calculator is a free online calculator that gives you an instant, accurate result as you type. Calculate the coefficient of variation (CV) from a mean and standard deviation to compare relative variability.
The calculation uses the standard formula CV = (σ / μ) × 100 and updates live with every change to the inputs. Everything runs client-side in your browser — fast, private, and free to use as often as you like.
Because CV is unitless, it lets you compare the variability of data sets measured in completely different units.
