Premiums are always calculated on the risk factors. Insurance is more like a game that is all about managing risks. Insurance companies do not want to take any risk. They try to know each and every thing in detail about the insured person. They try to find out whatever they need to know, even if the insurer tries to hide.
Your insurance premium depends on various factors. They scrutinize whether you suffer from any major ailments and try to check your smoking habits, cholesterol levels, obesity, diabetes, and other conditions. This could lead to poor health and a quicker death. They also look into age, gender and health. All these factors determine the premium that you will be required to pay for your life insurance.

You need to give your medical history and undergo a physical exam to determine your health status. You should always fill the accurate details in the health questionnaire. The company can cancel your insurance policy if you provide them with incorrect information, like if they come to know later, they will not pay your death benefits of your insurance policy.
Women have lower rates on life insurance because they live longer than men. Men pay a lower rate on an annuity. Younger people pay insurance premiums for a longer period till they are likely to die. However, you can pay a lower rate than an aged person, as they are healthier. Family medical history and lifestyle can play a major part in determining your life insurance premium.

Every company has a doctor for the physical exam. The doctor checks the insurer’s weight, blood pressure and other vital signs. X-ray or ECG, blood and urine samples are also tested for any sign of disease. They look especially for diseases like HIV virus, cholesterol level, and for any indications of diabetes, kidney problems, hepatitis and other problems. They also check nicotine content, medications and also whether illegal drugs are being taken by the insurer or not.
After this process, the company decides whether you are a preferred-plus, substandard buyer or any category in between. Then they set the premium rates accordingly. So, when you try to get insurance policy for yourself, discuss with the agent first and do what are the controllable health factors that can help you get premium bargains. Try to lose some weight, and take blood pressure medication regularly. It will definitely reduce some risk factor when it counts. Then inform your agent all the safety measures you have taken.
