Why? Because, there are many different types of life insurance, each insurer has their own set of rates, and your rate for life insurance depends on your own specific personal factors.
Life insurance premiums can vary based on the type and amount of life insurance requested, as well as, the insurance company.
In addition, your life insurance rate will depend on your own personal factors including your age, gender, health, family health history, occupation, hobbies, driving record, if you smoke or not, your height-to-weight ratio, if you take any medication, etc.
However, you may be able to determine your average cost of life insurance by comparing several different life insurance quotes online from multiple life insurance companies.
