About the Cholesterol Ratio Calculator
A ratio can tell more than one number alone — for example, high total cholesterol matters less when HDL (“good” cholesterol) is also high.
Formula explained
Total cholesterol ÷ HDL · LDL ÷ HDL · Triglycerides ÷ HDL
Total/HDL: below 3.5 ideal · below 5 desirable. LDL/HDL: below 2.5 desirable. TG/HDL (in mg/dL): below 2 good; higher values suggest insulin resistance.
Frequently asked questions
Which cholesterol ratio is most important?
The total cholesterol to HDL ratio is the most widely used. Your doctor will also look at LDL and your overall risk.
How can I improve my cholesterol ratio?
Regular exercise, losing belly fat, quitting smoking and replacing refined carbs with fibre-rich foods raise HDL and lower triglycerides.
