Cholesterol Ratio Calculator
Enter your lipid panel values (Total Cholesterol, HDL, LDL, Triglycerides) to instantly calculate cardiovascular risk ratios with colour-coded risk classification. All values in mg/dL. Free, private, no uploads.
Key Capabilities
Three cardiovascular risk ratios at once
Computes Total Cholesterol to HDL, LDL to HDL, and Triglyceride to HDL ratios simultaneously — giving a multi-angle view of cardiovascular risk that a single cholesterol value cannot provide.
Colour-coded risk classification per ratio
Each ratio is colour-coded against evidence-based thresholds — optimal, borderline, or high risk — making it immediately clear which aspect of your lipid profile needs clinical attention.
Accepts all four standard lipid panel values
Works with Total Cholesterol, HDL, LDL, and Triglycerides in mg/dL as printed on a standard lipid panel lab report, requiring no unit conversion for Indian or US patients.
How to Use
Enter your four lipid panel values
Input Total Cholesterol, HDL, LDL, and Triglycerides in mg/dL from your blood test report. All four values are needed for the complete cardiovascular risk picture.
Read all three ratios with colour-coded risk
Total/HDL, LDL/HDL, and Triglyceride/HDL ratios appear with colour indicators — green for optimal, amber for borderline, red for high risk.
Discuss elevated ratios with your doctor
Note which ratios fall outside the optimal range and bring this summary to your next cardiology or GP appointment for clinical context and any treatment decisions.
Common Use Cases
- Patients reviewing lipid results before a GP visitA patient who receives their annual lipid panel results enters all four values and arrives at their appointment already knowing which ratio is elevated and why it matters clinically.
- Cardiologists explaining metabolic syndrome riskA cardiologist uses the Triglyceride-to-HDL ratio output to demonstrate insulin resistance risk to a patient with a high-carbohydrate diet, making an abstract lab number tangible.
- Nutritionists tracking dietary intervention outcomesA clinical nutritionist tracks lipid ratio trends over quarterly panels to assess whether dietary changes are improving cardiovascular risk markers across a programme.
Frequently Asked Questions
Which cholesterol ratio is most important?
The Total Cholesterol to HDL ratio is considered the strongest predictor of cardiovascular risk. An optimal ratio is below 3.5. The Triglyceride to HDL ratio is a useful marker for insulin resistance and metabolic syndrome — a ratio above 3.0 is associated with increased risk.
What is a good HDL cholesterol level?
HDL (high-density lipoprotein) is protective — higher is better. Levels above 60 mg/dL are considered cardioprotective. Levels below 40 mg/dL in men or below 50 mg/dL in women are a cardiovascular risk factor.
What is the difference between LDL and HDL?
LDL (low-density lipoprotein) carries cholesterol to the arteries where it can build up as plaque — sometimes called 'bad cholesterol'. HDL (high-density lipoprotein) carries cholesterol back to the liver for removal — sometimes called 'good cholesterol'.
