Enter the total cholesterol (mg/dL) and the HDL cholesterol (mg/dL) into the Cholesterol Ratio Calculator. The calculator will evaluate and display the Cholesterol Ratio. 

Cholesterol Ratio Formula

The following formula is used to calculate the Cholesterol Ratio. 

CR = TC / HDL 

  • Where CR is the Cholesterol Ratio (Total:HDL)
  • TC is the total cholesterol (mg/dL) 
  • HDL is the HDL cholesterol (mg/dL) 

How to Calculate Cholesterol Ratio?

The following example problems outline how to calculate Cholesterol Ratio.

Example Problem #1:

  1. First, determine the total cholesterol (mg/dL). 
    • The total cholesterol (mg/dL) is given as: 200.
  2. Next, determine the HDL cholesterol (mg/dL). 
    • The HDL cholesterol (mg/dL) is provided as: 50.
  3. Finally, calculate the Cholesterol Ratio using the equation above: 

CR = TC / HDL 

The values given above are inserted into the equation below and the solution is calculated:

CR = 200 / 50  = 4 (Total:1)

Example Problem #2: 

For this problem, the variables required are provided below:

total cholesterol (mg/dL) = 300

HDL cholesterol (mg/dL) = 60

Test your knowledge using the equation and check your answer with the calculator above.

CR = TC / HDL  = ?
