Life insurance basics
Life insurance is a financial arrangement between a life insurance company and an individual in which the individual (the insurance policy holder) pays the insurance company (the insurer) a certain amount of money (the premium) with the guarantee that upon the death of the insured (either the insurance policy holder or another person), the insurer will pay a certain amount of money (the benefits) to the beneficiary or beneficiaries named in the policy . The payment of these benefits usually takes the form of either a lump sum or installments over a set period of time (known as an annuity).
In plain language, this means that if you purchase a life insurance policy and pay your policy's premiums on time, when you die the insurance company will pay your family the amount of money specified in the policy. You or your family will usually have a choice to receive the money either all at once or in installments.
Types of life insurance
There are two main types of life insurance: term insurance  and permanent (or whole life) insurance . Term insurance covers you for a set amount of time, while permanent insurance does not expire.
