📊 Cholesterol & Lipid Ratio Risk Evaluator
Enter your lipid values to evaluate metabolic and cardiac ratios.
What this calculator shows
From three numbers on a standard lipid panel (total cholesterol, HDL and triglycerides) the calculator works out:
- Total cholesterol ÷ HDL (the “cholesterol ratio”). Lower is better. Below 3.5 is desirable; above 5.0 is high.
- Triglycerides ÷ HDL. A high value (above about 4 in mg/dL units) often goes with insulin resistance and small, dense LDL particles.
- Non-HDL cholesterol (total minus HDL): all the cholesterol carried by particles that can build up in artery walls. Many guidelines use it as a treatment target, often below 130 mg/dL for people at average risk.
Units
Enter all values in mg/dL. If your report uses mmol/L, convert first: cholesterol and HDL × 38.67, triglycerides × 88.57. The total/HDL ratio is the same in both units, but the TG/HDL ratio is not, so convert before using it.
How doctors use these numbers
Ratios are a quick summary, but treatment decisions are usually based on LDL or non-HDL cholesterol together with your overall cardiovascular risk: age, blood pressure, smoking, diabetes, kidney function and family history. Two people with the same ratio can have very different risks.
- Fasting is not usually needed for a cholesterol test, but triglycerides are higher after a meal. If your triglycerides are above 400 mg/dL, ratios are less reliable.
- A single result can vary. Your doctor may repeat the test before changing treatment.
