Non-HDL Cholesterol Calculator
Calculate your non-HDL cholesterol, the sum of all the cholesterol carried by atherogenic particles, by subtracting HDL from total cholesterol. Non-HDL-C is a single number that captures more of your cardiovascular-relevant cholesterol than LDL alone, especially when triglycerides are high. Supports mg/dL and mmol/L. Informational reference, not a diagnostic test.
Non-HDL-C is a simple subtraction from your measured values. The reference bands below are published guideline goals, not personal targets. Discuss your lipid results with a healthcare provider.
What Non-HDL Cholesterol Tells You
Non-HDL cholesterol is exactly what its name says: all of your cholesterol except the HDL fraction. You get it by subtracting HDL from total cholesterol. Because it captures the cholesterol carried by every atherogenic (artery-clogging) particle, including LDL, VLDL, IDL, remnants, and lipoprotein(a), it is often a better single summary of cardiovascular-relevant cholesterol than LDL alone, particularly when triglycerides are elevated and a calculated LDL becomes unreliable.
Non-HDL-C does not require fasting and uses only two numbers on every lipid panel, which is part of why guideline bodies including the US NCEP and the European Society of Cardiology recommend it as a secondary or co-primary target alongside LDL.
Non-HDL-C = Total cholesterol − HDL cholesterolNo fasting required. Works directly in mg/dL or mmol/L.
Published Reference Goals
NCEP ATP III set non-HDL goals 30 mg/dL above the corresponding LDL goal (because a normal VLDL contributes about 30 mg/dL of cholesterol). The bands below are published guideline reference values, not personal targets; your goal depends on your overall cardiovascular risk.
| Non-HDL-C (mg/dL) | Non-HDL-C (mmol/L) | Published reference |
|---|---|---|
| Below 130 | Below 3.4 | Desirable (general population) |
| 130 – 159 | 3.4 – 4.1 | Above desirable |
| 160 – 189 | 4.1 – 4.9 | High |
| 190 and above | 4.9 and above | Very high |
Higher-risk individuals often have lower goals (for example, below 100 mg/dL / 2.6 mmol/L), set individually by a clinician.
