Coefficient of Variation (CV) Calculator
CV = σ / μ — relative variability as a percentage. Useful for comparing spread across different scales.

8.4% relative variability.
- Mean102.1429
- Sample SD8.5912
- CV (%)8.411
Step-by-step
- Mean = 102.1429, sample SD = 8.5912.
- CV = SD / |mean| × 100 = 8.5912 / 102.1429 × 100 = 8.411%.
How to use this calculator
- Enter your data.
- Read the CV as a percentage.
About this calculator
CV expresses standard deviation as a percentage of the mean — a unit-free measure of relative variability. Useful when comparing spread between datasets on different scales (e.g., comparing income variability across countries with different currency values).
Frequently asked
When the mean is close to zero — CV becomes unstable. For data that includes negative numbers, CV often doesn't make sense.
