Low Density Lipoprotein (LDL) Calculator
Low density lipoprotein (LDL), often referred to as “bad cholesterol,” plays a significant role in heart health. High LDL levels can lead to plaque buildup in your arteries, increasing the risk of heart disease and stroke. This calculator helps you estimate your LDL levels and understand your heart health better.
- Enter your total cholesterol and HDL cholesterol levels in mg/dL.
- Click “Calculate” to estimate your LDL levels and see the interactive chart.
- Use the expert guide below to understand your results and learn how to improve your LDL levels.
The Friedewald equation is used to estimate LDL cholesterol levels:
LDL = Total Cholesterol – HDL – (Triglycerides / 5)
Since triglycerides are not required for this calculator, we use the following simplified formula:
LDL ≈ Total Cholesterol – HDL – 20
| Total Cholesterol | HDL Cholesterol | Estimated LDL |
|---|---|---|
| 200 | 50 | 150 |
| 240 | 60 | 180 |
| 190 | 45 | 145 |
| LDL Level (mg/dL) | Risk Category |
|---|---|
| Below 100 | Optimal/Desirable |
| 100-129 | Near optimal/Above optimal |
| 130-159 | Borderline high |
| 160-189 | High |
| 190 or above | Very high |
- Regular exercise, a heart-healthy diet, and maintaining a healthy weight can help lower LDL levels.
- Quitting smoking and managing stress can also improve your heart health.
- If lifestyle changes aren’t enough, talk to your doctor about medication options.
What is the difference between LDL and HDL cholesterol?
LDL (low-density lipoprotein) is often called “bad cholesterol” because it can build up in your arteries, leading to heart disease. HDL (high-density lipoprotein) is often called “good cholesterol” because it helps remove excess cholesterol from your arteries.
