The timeframe to receive approval for a $25,000 life insurance policy will vary on factors such as the type of coverage and often the overall health of an individual applying for the life insurance coverage. For example, some plans can provide instant approval, while others may take days to weeks before approval can be made. Much of the timeframe will depend on whether a medical exam is required for the underwriting process. Most life insurance plans, such as term insurance with death benefit amounts under $100,000, will generally not require a medical exam for applicants age 65 and younger. However, if you are over 65, you may have to complete an exam which can delay the overall approval time. On the other hand, final expense plans require no medical exams at all, regardless of age.
