Buy term and invest the rest? Where I actually land

Few debates in personal finance generate more heat than term versus whole-of-life cover, with ILPs caught in the crossfire. Most of the heat comes from people defending whatever they already bought. Let me try to lay out the actual trade-offs, including the parts that are awkward for my own industry.
Term insurance is pure protection. You pay a premium, you're covered for a defined period, and if nothing happens the money is spent, exactly like your car insurance. No savings component means the cover is cheap relative to the payout: a healthy thirty-year-old can buy a large sum assured for the price of a few restaurant meals a month. The classic advice to buy term and invest the rest rests on this efficiency.
Whole-of-life policies bundle protection with a cash value that grows. Premiums run several times higher for the same cover, but the policy builds surrender value and doesn't expire at sixty-five. Fans value the permanence and the forced discipline. Critics point out that early premiums are heavily consumed by costs, and the same dollars invested separately might have done more. Both observations are fair, which is why the answer depends on the person, not the product.

Where does an ILP sit? It's the bundle made explicit. Your premium visibly splits between insurance charges and investment units, and you control the investment side through fund choices and switches. The transparency and control are real advantages. The cost layers that need watching, and the fact that investment risk sits with you, are real disadvantages. An ILP steered by written rules and checked daily is a different proposition from the same contract on autopilot. That difference is the entire reason PEAK, my framework exists.
So here's how I'd actually decide, in order.
Fix the protection number first. How much money does your family need if you stop existing tomorrow? That comes from your debts, your dependants, and the years of income you're replacing. Not from a brochure.
Second, secure that number affordably. For most young families, term cover does this job extremely well. I say that as someone whose industry earns more when you buy other things, so weigh the admission accordingly.
Third, and only after protection is solved, decide how to invest. Pick the vehicle whose costs and behaviour you'll actually manage. For some people that's a brokerage account and index funds. For others it's an ILP with a professional watching it. Both can work, and here is where the ILP case is strongest: if you know the rest will never actually get invested, buy term and invest the rest quietly becomes buy term and spend the rest, and ten years of that costs far more than any fee table. A bundled, monitored policy turns good intentions into a standing instruction, with someone accountable for steering it. What never works is the common outcome: underinsured while overpaying for a policy nobody manages.
Already own something and unsure if it still fits? Don't surrender anything in haste. Exits have costs, and older policies sometimes carry terms worth keeping. Map what you have against your protection number, then move deliberately.
One afternoon of that work beats a decade of vague guilt about a folder you haven't opened.
Ask yourself the only question that cuts through the whole debate: if I disappeared tomorrow, would my family have enough, and for how long? If you can't answer in numbers, start there. Everything else is decoration.
