This ratio is determined by dividing the HDL cholesterol into the total cholesterol. If a person has a total cholesterol of 200 mg/dL and an HDL cholesterol of 40 mg/dL, his or her total/HDL cholesterol ratio would be 5:1. The goal is to keep this ratio below 5:1, with the ideal being below 3.5:1.his ratio is determined by dividing the HDL cholesterol into the total cholesterol.
