The Lipid Profile Calculator is an essential tool for assessing cardiovascular health by analyzing key cholesterol markers—simply input your total cholesterol, HDL, and triglyceride levels to calculate LDL, VLDL, and non-HDL cholesterol using clinically validated formulas like Friedewald or Martin/Hopkins. With instant results in mg/dL or mmol/L, this calculator provides clear interpretations of your lipid profile, highlighting optimal, borderline, or high-risk values to help you understand your heart disease risk and track the effectiveness of lifestyle changes or medications. Quick, accurate, and user-friendly, it’s the perfect companion for anyone monitoring their heart health.
What Is a Lipid Profile?
A lipid profile is a blood test that measures fats (lipids) in your blood, including:
- Total Cholesterol (TC)
- LDL (“Bad”) Cholesterol
- HDL (“Good”) Cholesterol
- Triglycerides (TG)
- VLDL Cholesterol
These values help assess your risk of heart disease, stroke, and metabolic disorders.
How to Calculate Key Lipid Parameters
1. LDL Cholesterol (Friedewald Formula)
Estimates “bad” cholesterol when triglycerides are <400 mg/dL:
Example:
- TC = 200 mg/dL
HDL = 50 mg/dL
TG = 150 mg/dL - LDL = 200 – 50 – (150/5) = 120 mg/dL (Borderline High)
2. VLDL Cholesterol
Calculates very-low-density lipoprotein (triglyceride-rich particles):
Or
Example:
- TG = 150 mg/dL → VLDL = 150/5 = 30 mg/dL (Normal)
3. Non-HDL Cholesterol
Measures all “bad” lipoproteins (LDL + VLDL + remnants):
Example:
- TC = 200 mg/dL, HDL = 50 mg/dL → Non-HDL = 150 mg/dL (High)
4. Total Lipids
Estimates the sum of all lipids in blood:
Simplified estimate (if phospholipids unknown):
🧮 Lipid Profile Calculator
📐 Formulas:
- LDL (mg/dL) = Total Cholesterol - HDL - (Triglycerides / 5)
- VLDL (mg/dL) = Triglycerides / 5
- Total Lipid (mg/dL) = Total Cholesterol + Triglycerides + 200
- Ratios: TC/HDL, LDL/HDL, TG/HDL

Lipid Unit Conversion Factors
| Parameter | mg/dL → mmol/L | mmol/L → mg/dL | Example (mg/dL ↔ mmol/L) |
|---|---|---|---|
| Total Lipids | ÷ 38.67 | × 38.67 | 600 mg/dL ↔ 15.5 mmol/L |
| Total Cholesterol (TC) | ÷ 38.67 | × 38.67 | 200 mg/dL ↔ 5.2 mmol/L |
| Triglycerides (TG) | ÷ 88.5 | × 88.5 | 150 mg/dL ↔ 1.7 mmol/L |
| LDL Cholesterol | ÷ 38.67 | × 38.67 | 130 mg/dL ↔ 3.4 mmol/L |
| HDL Cholesterol | ÷ 38.67 | × 38.67 | 60 mg/dL ↔ 1.55 mmol/L |
| VLDL Cholesterol | ÷ 88.5 | × 88.5 | 30 mg/dL ↔ 0.34 mmol/L |
Normal Lipid Ranges
| Parameter | Optimal (mg/dL) | Optimal (mmol/L) |
|---|---|---|
| Total Cholesterol | <200 | <5.2 |
| LDL Cholesterol | <100 | <2.6 |
| HDL Cholesterol | ≥60 | ≥1.55 |
| Triglycerides | <150 | <1.7 |
| Non-HDL Cholesterol | <130 | <3.4 |

Example Lipid Profile Analysis
Input:
- Total Cholesterol = 220 mg/dL
- HDL = 40 mg/dL
- Triglycerides = 180 mg/dL
Results:
| Parameter | Value | Interpretation |
|---|---|---|
| LDL Cholesterol | 144 mg/dL | High |
| VLDL Cholesterol | 36 mg/dL | Borderline High |
| Non-HDL Cholesterol | 180 mg/dL | Very High |
| Total Lipids | 436 mg/dL | Normal |
Diagnosis: High cardiovascular risk → Lifestyle changes or statins may be needed.
Why Lipid Profiles Matter
- High LDL/NON-HDL: Linked to plaque buildup in arteries.
- Low HDL: Reduces protection against heart disease.
- High Triglycerides: Increases pancreatitis and metabolic syndrome risk.
Limitations
- Fasting Required: Triglycerides rise after eating.
- Inaccurate if:
- TG ≥400 mg/dL (use direct LDL measurement).
- Liver/kidney disease present.
