Life insurance is a financial contract between an individual and an insurance company designed to provide economic security to loved ones in the event of the policyholder's death. In exchange for regular payments called premiums, the insurer guarantees to pay a tax-free lump sum—known as a death benefit—to named beneficiaries (like family members) when the insured passes away. This payout acts as a safety net, helping dependents cover immediate final expenses, replace lost income, pay off outstanding debts like mortgages, and secure long-term future goals like a child's education.
