Cholesterol Ratio Calculator: Assess Your Heart Health Risk

Get a clearer picture of your heart health. Enter your cholesterol numbers to calculate your Total Cholesterol to HDL ratio, a key indicator of cardiovascular risk.

What Is the Cholesterol Ratio and Why Is It Important?

While your total cholesterol number is important, the cholesterol ratio provides a more insightful look at your risk for heart disease. It measures your total cholesterol relative to your "good" cholesterol (HDL). A lower ratio is better, as it indicates a healthier balance between total cholesterol and the HDL cholesterol that helps clear arteries.

Cholesterol Ratio = Total Cholesterol ÷ HDL ("Good") Cholesterol

Understanding Your Ratio: Risk Levels

A lower ratio is considered ideal for heart health. Here’s a breakdown of what the numbers generally mean:

Risk LevelCholesterol Ratio
Optimal / DesirableLess than 3.5
Average Risk3.5 – 5.0
High RiskGreater than 5.0
