Get a clearer picture of your heart health. Enter your cholesterol numbers to calculate your Total Cholesterol to HDL ratio, a key indicator of cardiovascular risk.
While your total cholesterol number is important, the cholesterol ratio provides a more insightful look at your risk for heart disease. It measures your total cholesterol relative to your "good" cholesterol (HDL). A lower ratio is better, as it indicates a healthier balance between total cholesterol and the HDL cholesterol that helps clear arteries.
Cholesterol Ratio = Total Cholesterol ÷ HDL ("Good") Cholesterol
A lower ratio is considered ideal for heart health. Here’s a breakdown of what the numbers generally mean:
| Risk Level | Cholesterol Ratio |
|---|---|
| Optimal / Desirable | Less than 3.5 |
| Average Risk | 3.5 – 5.0 |
| High Risk | Greater than 5.0 |

Calculates the ratio between total cholesterol and HDL cholesterol from the values entered.
The calculator divides total cholesterol by HDL cholesterol to provide a simple ratio alongside the entered values. The calculation uses total cholesterol and HDL cholesterol.
Cardiovascular risk cannot be determined from a cholesterol ratio alone; LDL, triglycerides, blood pressure, age, smoking and other factors matter. Use the number as an estimate and consider professional advice when the result may affect health, treatment, pregnancy, nutrition, exercise safety or another important decision.
