About this calculator

This calculator finds non-HDL cholesterol from a standard lipid panel. Non-HDL cholesterol is often useful because it includes LDL cholesterol plus other atherogenic particles such as VLDL.

Use the result as a discussion aid, not as a medication decision. Your treatment target depends on age, diabetes, kidney disease, prior cardiovascular disease, blood pressure, smoking, and clinician judgment.

Source-backed
Non-HDL cholesterol is calculated as total cholesterol minus HDL cholesterol. It represents cholesterol carried by atherogenic particles including LDL and VLDL, but treatment targets depend on overall cardiovascular risk and clinician guidance.
Review status
Activated — non-HDL cholesterol formula
Limitations
Educational estimate only; not a diagnosis, prescription, or treatment plan.

Formula and method

Non-HDL cholesterol = total cholesterol − HDL cholesterol. The calculator supports mg/dL and mmol/L as long as both input values use the same unit.

Medical safety note: This page is for education only and should not replace professional medical advice. For emergencies, medication decisions, or severe symptoms, contact a qualified clinician or local emergency service.

Limitations and when not to rely on this result

  • Educational estimate only; not a diagnosis, prescription, or treatment plan.
  • Result depends on accurate inputs and may not apply to complex medical situations.
  • Use clinician judgment, local guidance, and urgent care pathways when symptoms are severe.

Frequently asked questions

What is non-HDL cholesterol? +

It is total cholesterol minus HDL cholesterol. It includes LDL and other non-HDL particles that can contribute to atherosclerosis.

Why calculate non-HDL if I already have LDL? +

Non-HDL cholesterol can be useful when triglycerides are elevated or when clinicians want a broader atherogenic cholesterol measure.

Is there one normal non-HDL target for everyone? +

No. Targets vary by cardiovascular risk, prior disease, diabetes, kidney disease, and local guideline approach.

Do I need to fast for non-HDL cholesterol? +

Non-HDL can often be calculated from a non-fasting lipid panel, but follow the instructions from your clinician or lab.

Can this decide whether I need medication? +

No. Lipid treatment depends on overall cardiovascular risk and clinician assessment.
