Cholesterol Ratio & LDL Calculator
Enter your recent lipid panel results to calculate your LDL cholesterol (if not directly measured) and your Total Cholesterol to HDL ratio, along with general interpretations.

Cholesterol is a waxy, fat-like substance found in all the cells in your body. Your body needs some cholesterol to make hormones, vitamin D, and substances that help you digest foods. However, too much cholesterol can be a problem. It can combine with other substances to form plaque, which sticks to the walls of your arteries, narrowing them and making them less flexible. This condition, called atherosclerosis, can lead to coronary artery disease and other heart-related issues.
The Different Types of Cholesterol
When you get a lipid panel, you'll typically see several numbers:
- Total Cholesterol: This is the sum of all the cholesterol in your blood, including LDL and HDL.
- LDL (Low-Density Lipoprotein) Cholesterol: Often called "bad" cholesterol, LDL contributes to fatty buildups in arteries. High LDL levels increase your risk for heart disease and stroke.
- HDL (High-Density Lipoprotein) Cholesterol: Known as "good" cholesterol, HDL helps remove excess cholesterol from your arteries and carries it back to the liver, where it's processed and removed from the body. Higher HDL levels are generally protective.
- Triglycerides: These are a type of fat in your blood. Your body converts any calories it doesn't need to use right away into triglycerides, which are stored in your fat cells. High triglycerides can increase your risk of heart disease, especially in combination with high LDL or low HDL cholesterol.
How the Calculator Works
Our Cholesterol Ratio & LDL Calculator uses your Total Cholesterol, HDL Cholesterol, and Triglycerides to provide a more comprehensive view of your lipid profile:
- Calculated LDL Cholesterol: If your LDL wasn't directly measured, this calculator estimates it using the Friedewald equation:
LDL = Total Cholesterol - HDL - (Triglycerides / 5). This formula is widely used but is most accurate when triglyceride levels are below 400 mg/dL. If your triglycerides are very high, a direct LDL measurement is usually required. - Total Cholesterol/HDL Ratio: This ratio is often considered a better predictor of heart disease risk than total cholesterol alone. A lower ratio generally indicates a lower risk. For example, a ratio of 3.0 is considered excellent, while a ratio of 5.0 or higher suggests increased risk.
Interpreting Your Results (General Guidelines)
While the calculator provides interpretations, these are general guidelines. Your individual risk factors, medical history, and overall health play a crucial role in determining what numbers are optimal for you. Always discuss your results with your doctor.
General Cholesterol Level Guidelines:
- Total Cholesterol:
- Desirable: Less than 200 mg/dL
- Borderline High: 200-239 mg/dL
- High: 240 mg/dL and above
- LDL Cholesterol:
- Optimal: Less than 100 mg/dL
- Near Optimal/Above Optimal: 100-129 mg/dL
- Borderline High: 130-159 mg/dL
- High: 160-189 mg/dL
- Very High: 190 mg/dL and above
- HDL Cholesterol:
- Poor (Risk Factor): Less than 40 mg/dL
- Better: 40-59 mg/dL
- Excellent (Protective): 60 mg/dL and above
- Triglycerides:
- Normal: Less than 150 mg/dL
- Borderline High: 150-199 mg/dL
- High: 200-499 mg/dL
- Very High: 500 mg/dL and above
Managing Your Cholesterol
If your cholesterol levels are not in the desirable range, there are several lifestyle changes you can make to improve them:
- Diet: Reduce saturated and trans fats, cholesterol, and added sugars. Increase fiber intake (fruits, vegetables, whole grains) and consume healthy fats (monounsaturated and polyunsaturated fats found in avocados, nuts, seeds, and olive oil).
- Exercise: Regular physical activity can help lower LDL and raise HDL cholesterol. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week.
- Weight Management: Losing excess weight can significantly improve cholesterol levels.
- Quit Smoking: Smoking damages blood vessels and lowers HDL cholesterol. Quitting can improve your lipid profile.
- Limit Alcohol: Excessive alcohol consumption can increase triglyceride levels.
For some individuals, lifestyle changes may not be enough, and medication might be necessary. Always consult your healthcare provider to develop a personalized plan for managing your cholesterol and reducing your risk of heart disease.
