The following is my answer to a Quora question: “What arguments exist for whole life insurance over term life insurance?”
Both whole life and term have their uses. Generally, I recommend whole life when the client is younger. If they can afford it, I recommend a limited pay whole life, so they pay for the coverage during their earning years only. When taken early, whole life is cheap. It will never be cheaper than a term plan, but when we calculate the total premium of a whole life plan over the course of the payment term against multiple term plans taken at successively later periods of life, whole life premiums are much cheaper.

Secondly, whole life plans have a surrender value; term plans do not. This makes them a financial instrument that can be borrowed against if it absolutely becomes necessary.
Finally, whole life coverage for the duration of the plan, once incepted, is guaranteed. When a term plan is up for renewal, and there is a claim against it, that renewed term plan may not cover the condition claimed against, treating it as a pre-existing condition. This may not be true for all term plans, however.

Sometimes, customers, even financial planners, get carried away with the notion of “buy term, invest the rest”, as though it is the only right way to plan one’s finances and insurance.
Yet, individual circumstances differ. Hence, the financial and insurance planning differ as well.
Each insurance product type is created with a purpose. It has its advantages and disadvantages.
Hence, when it comes to insurance and financial planning, it is not about what product you should buy but how the product(s) fit into your overall financial plan and objectives.
