# Non-HDL Cholesterol Calculator

> Free non-HDL cholesterol calculator. Subtract HDL from total cholesterol to get non-HDL-C, with published reference goals. Inputs in mg/dL or mmol/L.

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.

## 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.

 **Formula:** `Non-HDL-C = Total cholesterol − HDL cholesterol`
 No 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.

## Frequently Asked Questions

 What is non-HDL cholesterol? Non-HDL cholesterol is your total cholesterol minus your HDL cholesterol. It represents the cholesterol carried by all the atherogenic (artery-clogging) particles together, including LDL, VLDL, remnants, and lipoprotein(a). Because it captures more than LDL alone, guideline bodies use it as a target for cardiovascular risk, especially when triglycerides are high. What is a good non-HDL cholesterol level? For the general population, a non-HDL-C below 130 mg/dL (3.4 mmol/L) is commonly cited as desirable, following NCEP ATP III, which set non-HDL goals 30 mg/dL above the LDL goal. Higher-risk people often have lower individualised goals. These are published reference values, not personal targets; your clinician sets the right goal for your risk. Why use non-HDL instead of LDL? LDL on a lab report is usually calculated and becomes unreliable when triglycerides are high or the sample is non-fasting. Non-HDL-C is a direct subtraction of two measured values, needs no fasting, and reflects all atherogenic cholesterol, so it is often a more robust single number, particularly in people with high triglycerides, diabetes, or metabolic syndrome. Do I need to fast for non-HDL cholesterol? No. Total cholesterol and HDL are stable whether or not you have eaten, so non-HDL-C can be calculated from a non-fasting sample. This is one of its practical advantages over a calculated LDL, which depends on triglycerides that rise after meals. Can I enter mmol/L values? Yes. Switch the unit toggle to mmol/L. Non-HDL-C is a simple subtraction, so the calculator works directly in whichever unit you choose and shows the result in the same unit, with the matching published reference band. **Medical Disclaimer:** Non-HDL cholesterol is calculated as total cholesterol minus HDL. The reference goals shown follow published guidelines (NCEP ATP III; ESC/EAS) and are general population values, not personal treatment targets, which depend on your individual cardiovascular risk.
