LDL Cholesterol Calculator
Calculate your estimated LDL cholesterol level using the Friedewald formula. Input your total cholesterol, HDL, and triglyceride values.
Step 1: Cholesterol Values (mg/dL)
About LDL Calculation
LDL is calculated using the Friedewald formula: LDL = Total Cholesterol – HDL – (Triglycerides/5). Note: This formula is less accurate when triglycerides exceed 400 mg/dL.
Step 2: Additional Factors
Risk Factors
Diabetes, smoking, hypertension, and family history of heart disease increase your cardiovascular risk. Lower LDL targets may be recommended.

Cholesterol Breakdown
Friedewald Formula
LDL = Total Cholesterol – HDL – (Triglycerides/5)
Example: LDL = 200 – 50 – (150/5) = 200 – 50 – 30 = 120 mg/dL
Alternative: LDL = Total Cholesterol – HDL – (Triglycerides × 0.2)
