How It Works

How It Works

This calculator finds the ratio between your LDL ("bad") cholesterol and HDL ("good") cholesterol. It simply divides your LDL value by your HDL value using the formula: LDL ÷ HDL.

Because both numbers are measured in the same unit (mg/dL), the units cancel out. The result is a single number that shows how much LDL you have compared to HDL.

  • Enter your LDL cholesterol value (mg/dL)
  • Enter your HDL cholesterol value (mg/dL)
  • The calculator divides LDL by HDL
  • The result is shown as a unitless ratio
  • The value may be rounded to 2 decimal places

Understanding the Results

The LDL/HDL ratio helps show the balance between harmful and protective cholesterol in your blood. A lower ratio generally means a healthier balance, while a higher ratio may suggest greater cardiovascular risk.

This number does not replace medical advice, but it can help you better understand your cholesterol profile when reviewing lab results.

  • Lower ratios are generally better
  • Higher ratios may indicate increased heart risk
  • The ratio reflects balance, not total cholesterol
  • Always discuss results with your healthcare provider
