Cholesterol Ratio Calculator
Calculate your total-to-HDL, LDL-to-HDL, and triglyceride-to-HDL cholesterol ratios from a lipid panel. Shows how your HDL compares with your other numbers.

A lipid panel gives you four numbers, but the ratios between them often say more than any single value. This tool works out the total-to-HDL, LDL-to-HDL, and triglyceride-to-HDL ratios so you can see how protective your HDL is relative to the rest.
How this is calculated
The total-to-HDL ratio divides total cholesterol by HDL, the LDL-to-HDL ratio divides LDL by HDL, and the triglyceride-to-HDL ratio divides triglycerides by HDL. A total-to-HDL ratio under 3.5 is often labeled optimal, under 5 acceptable, and higher values carry more risk. These thresholds are general guidance, not a diagnosis.
How to use
- Read your total cholesterol, HDL, LDL, and triglycerides from a lipid panel (all in mg/dL).
- Enter each value.
- Read your three cholesterol ratios and the total-to-HDL rating.
Examples
- Total 200, HDL 50, LDL 120, TG 150:
Total/HDL 4.0 (Good), LDL/HDL 2.4, TG/HDL 3.0 - Total 180, HDL 60, LDL 100, TG 90:
Total/HDL 3.0 (Optimal)
FAQ
- What is a good cholesterol ratio?
- A total-to-HDL ratio below about 3.5 is considered ideal and below 5 is acceptable. Lower is better because it means HDL makes up a larger share of your cholesterol.
- Is this a substitute for medical advice?
- No. Ratios are one piece of the picture. Discuss your full lipid panel, family history, and other risk factors with your doctor.
