Cholesterol Ratio Calculator

What do these numbers mean?

Cholesterol ratios provide a more complete picture of cardiovascular risk than any single cholesterol number alone. They reflect the balance between harmful and protective lipoproteins circulating in your blood.

Total/HDL ratio is widely used as a quick risk indicator. It shows how much of your total cholesterol is made up of protective HDL. A lower number is better because it means a larger proportion of your cholesterol is the heart-protective type.

LDL/HDL ratiodirectly compares the “bad” cholesterol that contributes to plaque buildup with the “good” cholesterol that helps remove it. This ratio is especially useful for assessing your risk of developing atherosclerosis.

Triglyceride/HDL ratio is considered one of the strongest predictors of insulin resistance and metabolic syndrome. A high ratio often signals that the body is struggling to process fats and sugars efficiently, even when other numbers look acceptable.

Non-HDL cholesterol captures all the potentially harmful cholesterol particles in one number (Total minus HDL). Many cardiologists now consider it a better predictor of heart disease than LDL alone because it includes VLDL and other atherogenic particles.
