Term Life vs. Whole Life Insurance: Why "Buy Term and Invest the Difference" Dominates
Life insurance serves one primary economic purpose: to replace your income and protect your financial dependents if you pass away prematurely.
When shopping for coverage, consumers are faced with two fundamentally different product categories:
- Term Life Insurance: Pure, straightforward insurance protection that covers you for a specific period (e.g., 20 or 30 years). If you pass away during the term, your beneficiaries receive a tax-free cash death benefit. If you outlive the term, the policy simply expires.
- Whole Life Insurance (Permanent): A complex financial product that combines permanent death benefit protection with an internal "cash value" savings/investment account.

Frequently Asked Questions (FAQ)
How much life insurance coverage do I need?
A standard rule of thumb is 10x to 12x your annual gross salary in term life coverage. For example, if you earn $80,000 per year, aim for an $800,000 to $1,000,000 20-or-30-year level term policy to replace your income and clear the mortgage.
