Cholesterol Ratio Calculator (HDL/LDL + more)

Enter the triglycerides, HDL (high-density lipoprotein), and LDL (low-density lipoprotein) into the calculate to determine your cholesterol ratios. These ratios include total cholesterol to hdl, triglycerides to hdl, and ldl/hdl ratios.

Cholesterol Ratio Formulas

The following formulas are used back the cholesterol ratio calculator above.

TC = HDL + LDL + 0.2 * TG



  • Where TC is total cholesterol
  • HDL is high-density lipoproteins
  • LDL is low-density lipoproteins
  • TG is triglycerides.

In this case, the ratios are simple division, but the more complex formula is the one for calculating total cholesterol. Most people think that total cholesterol is equal to the LDL plus the HDL. In reality, a small portion of cholesterol is added through triglycerides. That small portion is 20% of the total triglycerides.

The units for this calculator are not defined. They can be any measure of units as long as the units are equal throughout. This is because ratios needed to have equal units to be relevant.
