This calculator computes two cholesterol ratios commonly cited alongside a standard lipid panel: Total Cholesterol / HDL, and LDL / HDL. This calculator is for general reference and educational purposes only — it is not a medical diagnosis. Consult a doctor for actual cardiovascular risk assessment.
How it works
Enter your total cholesterol, HDL, and LDL values (all in mg/dL) from a lipid panel. The tool divides total cholesterol by HDL, and LDL by HDL.
- Enter total cholesterol (mg/dL).
- Enter hDL cholesterol (mg/dL).
- Enter lDL cholesterol (mg/dL).
- Click Calculate to see your results.
Examples
Total 200, HDL 50, LDL 120 (mg/dL)
Total/HDL ratio = 200/50 = 4.0. LDL/HDL ratio = 120/50 = 2.4.
Who should use it
- Reviewing lipid panel results alongside a doctor.
- General cardiovascular health education.
Industry applications
- Primary care and cardiology reference
- Patient health education
Advantages
- Simple, transparent arithmetic from values you already have on a lipid panel.
- Ratios are widely referenced in patient education materials.
Limitations
- Ratios alone do not replace a full cardiovascular risk assessment.
- Reference targets vary by guideline and individual risk factors.
Common mistakes to avoid
- Using non-fasting lipid values, which can affect triglyceride-derived numbers like calculated LDL.
- Treating a single ratio in isolation instead of the full lipid panel and overall risk profile.
Best practices
- Track your cholesterol ratios over time using panels drawn under similar conditions (e.g. fasting).
Tips
- Discuss your full lipid panel — not just the ratios — with your doctor for actual risk assessment.
