A normal or healthy score for total cholesterol is anything below 180 to 200 milligrams per deciliter of blood, according to the American Heart Association. Good cholesterol, or high-density lipoprotein, levels should be above 60 milligrams per deciliter, advises MedlinePlus.
Bad cholesterol, or low-density lipoprotein, levels should remain below 100 milligrams per deciliter, notes MedlinePlus. Total cholesterol is calculated by adding the tallies for HDL and LDL together along with 20 percent of the score for triglycerides, a common type of fat found within the body, explains the American Heart Association.
Ideally, triglyceride levels should be below 150 milligrams per deciliter. Levels below 100 milligrams per deciliter are considered optimal and can be achieved by eating a healthy diet and exercising regularly, reports Mayo Clinic.
