All policies are not the same. Some give coverage for your lifetime and other cover you for a specific number of years. Some build up cash values and others do not. Some policies combine different kinds of insurance, and others let you change from one kind of insurance to another. Some policies may offer other benefits while you are still living. There are two basic types of life insurance: term insurance and permanent insurance.
Term insurance generally has lower premiums in the early years, but does not build up cash values that you can use in the future. You may combine cash value life insurance with term insurance for the period of your greatest need for life insurance to replace income.
Term insurance covers you for a term of one or more years. It pays a death benefit only if you die in that term. Term insurance generally offers the largest insurance protection for your premium dollar. It generally does not build up cash value.
You can renew most term insurance policies for one or more terms, even if your health has changed. Each time you renew the policy for a new term, premiums may be higher. Ask what the premiums will be if you continue to renew the policy. Also ask if you will lose the right to renew the policy at a certain age. For a higher premium, some companies will give you the right to keep the policy in force for a guaranteed period at the same price each year. At the end of that time you may need to pass a physical examination to continue coverage, and premiums may increase. You may be able to trade many term insurance policies for a cash value policy during a conversion period even if you are not in good health. Premiums for the new policy will be higher than you have been paying for the term insurance.
Permanent insurance (such as universal life, variable universal life and whole life) provides long-term financial protection. These policies include both a death benefit and, in some cases, cash savings. Because of the savings element, premiums tend to be higher.
