Why Bundling Insurance With Investing Usually Costs More

Money has three jobs — save, invest, insure. A product that mixes them is harder to judge on any one. (Back to first principles.)

This pillar opened with a simple idea: money does three jobs — to save, to invest, and to insure — and trouble starts when one product tries to do several at once. Bundled insurance products, from whole life to investment-linked plans, are that idea in practice.

The problems are consistent. First, the two jobs compromise each other, and it helps to see exactly how. The protection inside a bundle is usually permanent cover, which costs far more than the plain term insurance you could buy for the same payout. The investment, meanwhile, sits inside an insurance wrapper that adds its own policy charges and sales costs on top of the fund's own fees — so your money grows more slowly than it would in a low-cost fund bought directly. In short, you pay more for the protection and earn less on the investment than if you had bought each on its own. Second, the costs are opaque — one combined price hides whether either job is good value. Third, bundled products often carry lock-in: surrender early and you can get back less than you paid. Fourth, they are hard to compare, because no two are built quite alike.

None of this makes bundled products fraudulent or always wrong. They can suit people who value simplicity and want their saving enforced. But the burden of proof should be high, because the default — buy term, invest separately, hold cash savings — is cheaper, clearer and more flexible for most people.

The test is the one from the first post: can you say which job this product is doing, and whether it does that job well and cheaply? If a bundle makes that hard to answer, that difficulty is itself the warning.
