Your initial life insurance premium quote provides an estimate, based on your policy details (payment term, coverage amount, riders, etc.), and some basic personal information (age, gender, smoking status). This gives you a general idea of what a person in your demographic would pay for the coverage you selected. When you submit your application, the underwriter can then use the other personal information provided (health, medical details, lifestyle, occupation, family history, etc.) to evaluate what level of risk you pose. It may be determined that you are a standard risk, which would mean that your premiums would match the quoted premium. You may also find that you have a higher or lower rating, which would increase or decrease the monthly premium respectively.
