Estimate VLDL cholesterol from triglycerides with the Friedewald equation, in mg/dL or mmol/L, with the usual range.
Result
How to use this tool
Enter fasting triglycerides.
Choose mg/dL or mmol/L.
Read VLDL in both units.
Treat very high triglycerides as unreliable for this estimate and get a full lipid panel.
Formula & worked example
Triglycerides of 150 mg/dL give VLDL of 150 / 5 = 30 mg/dL, inside the often-quoted usual range of 5 to 40 mg/dL.
Limitations — read this before you rely on it
Friedewald estimate only, not a direct measurement; unreliable above 400 mg/dL triglycerides. This tool is for education only and is not medical advice. Talk to a clinician about any result that worries you, and never change treatment because of a calculator result.
Frequently asked questions
Very-low-density lipoprotein, the particle that carries most fasting triglycerides in blood.
In fasting blood, VLDL cholesterol is roughly one fifth of total triglycerides by mass.
When triglycerides exceed 400 mg/dL, or in type III hyperlipidaemia and some other disorders.
No. LDL is a separate, denser particle and the main treatment target; VLDL adds extra risk information.
Excess calories, sugar, alcohol, obesity, diabetes and some medicines.
