Total Cholesterol, LDL & HDL Calculator
Reference values for cholesterol come from large population studies (NHANES, WHO). They provide a framework for interpreting your results, but your personal health context always comes first. Target ranges: Total <200, LDL <100, HDL >60 (men >40, women >50). Values are current as of 2026 and reviewed periodically to keep you up-to-date.

How it works
1 min readHealthy cholesterol values come from large population studies (NHANES, WHO, CDC). They vary by age, sex, ethnicity, and region. They're guidelines; your personal medical history always takes priority.
How It's Calculated
Target ranges: Total <200, LDL <100, HDL >60 (men >40, women >50).
This calculator applies the formula with your input values, checks typical ranges, and alerts you to any unusual readings.
Normal Reference Ranges
| Parameter | Normal Range (Adults) |
|---|---|
| Blood Pressure | <120/80 mmHg |
| Resting Heart Rate | 60-100 bpm |
| Temperature | 36.1-37.2°C |
| Oxygen Saturation (SpO2) | 95-100% |
| Fasting Glucose | 70-100 mg/dL |
| HbA1c | <5.7% |
| Total Cholesterol | <200 mg/dL |
| LDL Cholesterol | <100 mg/dL |
| HDL Cholesterol | >40 (men) / >50 (women) |

Frequently asked questions
What are normal cholesterol levels?
Target ranges are: Total cholesterol <200 mg/dL, LDL <100 mg/dL, and HDL >60 mg/dL (men >40, women >50). Individual targets may vary based on age, sex, and health conditions.
What's the difference between LDL and HDL cholesterol?
LDL ('bad' cholesterol) builds up in arteries and increases heart disease risk. HDL ('good' cholesterol) removes excess cholesterol and protects your heart. Higher HDL levels are better.
What is considered high cholesterol?
Total cholesterol of 200 mg/dL or higher is considered high. LDL above 100 mg/dL may require lifestyle changes or medication depending on your overall cardiovascular risk.
When should I see a doctor about cholesterol?
See a doctor if your cholesterol values are outside normal ranges, if you have symptoms, or if you have a family history of heart disease or metabolic disorders.
Do medications affect cholesterol levels?
Yes, many medications (statins, beta-blockers, diuretics) can affect cholesterol and other lipid levels. Always inform your doctor about any medications before getting tested.
Are cholesterol targets different for men and women?
Yes, HDL targets differ: men should aim for >40 mg/dL while women should aim for >50 mg/dL. Overall targets for total cholesterol and LDL are the same.
How often should I get my cholesterol checked?
Adults should have their cholesterol checked every 4-6 years. More frequent testing may be needed if you have high cholesterol, heart disease, or other risk factors.
Can diet and exercise lower cholesterol?
Yes. A heart-healthy diet (low in saturated fats), regular exercise, maintaining a healthy weight, and not smoking can significantly improve cholesterol levels.
