Cholesterol Ratio Calculator
Evaluate your heart health by calculating your Total Cholesterol to HDL ratio and estimating LDL.
Calculations use the Friedewald formula. For medical diagnosis, always consult your physician.
How This is Calculated
Total-to-HDL ratio = Total Cholesterol ÷ HDL. LDL is estimated via the Friedewald equation: LDL = Total Cholesterol − HDL − (Triglycerides ÷ 5) (valid when triglycerides <400 mg/dL). AHA considers a ratio <3.5 desirable; above 5 indicates high cardiovascular risk.
