If you have a regular term life insurance policy and are alive when the term ends, you would get no money-back.
However, if you purchased a return of premium term life insurance policy, you would get back most of the premiums you paid, if you outlive the duration of your life insurance policy.
Keep in mind, a return premium term policy charges higher premiums for the life insurance coverage, but if you outlive the policy term, you'll get back almost all of the premiums you paid.
