An Endowment policy offers a combined long-term investment and insurance policy. Insurance is provided until a nominated maturity age, and bonuses add value to the sum insured.
Cover is provided until the policy matures, or upon the earlier death of the insured person.
This type of policy has the advantage of providing for regular savings with protection during the chosen period and can be used for many purposes such as:


saving for retirement


repayment of a debt, if death occurs before the loan is repaid (for example, mortgage protection) , or


providing funds for travel or for any future purposes which require funds (such as children's education).

In short, both of the above policies are entirely different things. And you should Invest in them according to your needs and Financial Goals.
