"Buy Term and Invest the Difference"
Separate the jobs, and you can see — and judge — each one. (The case for unbundling.)
"Buy term and invest the difference" is one of the most repeated lines in personal finance. The logic: term cover is far cheaper than whole life for the same protection, so buy term, and invest the premium you save. Over a long horizon, the argument runs, your own investments should outgrow the savings built into a whole-life policy — and you keep protection and investing separate, where each can be judged on its own.
The case for it is real. Unbundling is cheaper and more transparent; you see exactly what protection costs and exactly how your investments perform, and you can change either without disturbing the other.
The caveats are just as real. The strategy only works if you actually invest the difference — consistently, for decades, without dipping in. Buy the cheap term but merely leave the difference in a bank account, and low interest can leave you behind even a whole-life policy's forced saving. And many people quietly spend the difference, ending with neither the cover nor the pot. A bundled policy, for all its cost, at least forces the saving.
So the honest verdict is conditional. For a disciplined saver who will invest the difference, buying term and investing usually wins. For someone who knows they will not, the forced saving of a bundled policy may be the lesser evil. Be honest about which you are.
Illustrative example: two routes, weighed
The chart shows three illustrative 30-year outcomes. Buying term and investing the difference can finish well ahead of a whole-life policy's cash value — but only if the difference is genuinely invested. Buy term and simply leave the difference in a bank account, and low interest leaves you behind even the whole-life policy. The route you pick matters less than whether you actually invest.
