Yes, whole life insurance does build cash value over time. Cash value is a feature of whole life insurance policies that allows the policyholder to accumulate savings within the policy while also providing a death benefit. The cash value grows over time through a combination of premium payments and interest or investment returns, depending on the specific policy. This cash value can be accessed by the policyholder through policy loans or withdrawals, providing a source of funds that can be used for various purposes. It's important to note that accessing the cash value may affect the death benefit and could have tax implications, so it's advisable to consult with a financial advisor or insurance professional before making any decisions regarding the cash value of a whole life insurance policy.
