How does cash value work in a permanent life insurance policy?

Cash value is a savings component inside permanent policies (whole and universal life) that grows tax-deferred over time. Part of each premium pays for the actual insurance, part covers fees, and the rest goes into the cash value, which earns interest or dividends. In the early years almost nothing accumulates because costs are front-loaded; it builds more meaningfully after 10–15 years. You can borrow against it, withdraw from it, or surrender the policy for the cash, but here's the catch many people miss: when you die, the insurer typically pays only the death benefit, not the death benefit plus cash value — any unborrowed cash value is effectively absorbed. Withdrawals above your premium basis can be taxable, and surrender charges may apply in early years. Treat cash value as a long-horizon feature, not quick savings.
