The Cholesterol Ratio Calculator computes the ratio of total cholesterol to HDL (good) cholesterol to provide an estimate of cardiovascular risk. A lower ratio generally indicates healthier lipid balance, while higher ratios may indicate elevated heart disease risk. Users input total and HDL cholesterol values, and the calculator classifies the result as Optimal, Average, or High Risk. This tool is useful for monitoring heart health trends but should be complemented with medical guidance and full lipid profile evaluation.
