In a money-back insurance policy, the insurer agrees to pay a portion of the sum assured at predetermined intervals during the policy term, provided the insured survives.

They are distinct from maturity claims, which occur at the end of the policy term, and death claims, which occur upon the demise of the insured.

Pensions and life insurance serve complementary roles in financial planning. Life insurance mitigates the financial risk associated with premature death by providing a lump sum, whereas pensions mitigate the risk of longevity (outliving one's savings) by providing a stream of income. Furthermore, the accumulation phase of life insurance builds a sum assured, while the payout phase of a pension systematically liquidates a corpus to provide retirement income.
