Few decisions in personal finance are argued about more — and understood less — than term vs. whole life insurance. The online consensus says "buy term and invest the difference." The industry consensus says "whole life is the only permanent solution." Both are wrong as blanket advice, because term and whole life solve fundamentally different problems.
Here's a clean framework for figuring out which you actually need.
What term insurance does
Term is pure insurance. You pay an annual premium; if you die during the term (typically 10, 20, or 30 years), your beneficiaries get the death benefit. If you outlive the term, the policy ends and you get nothing back.
Term solves temporary, capped risks. The classic examples:
- A young family with a mortgage, dependent children, and 20 years until the kids are self-sufficient and the mortgage is paid off. Their insurance need is time-limited — it shrinks every year as the kids grow up and the mortgage amortises.
- A business partner whose buy-sell agreement needs funding while the business is still growing. Once retirement age arrives and the business is sold, the need disappears.
- Income replacement during peak earning years, when your family's standard of living depends on your paycheque.
What whole life does
Whole life is a bundled product: pure insurance + a forced savings account (the cash value). Premiums are significantly higher than term, a portion funds the death benefit, and the rest grows tax-sheltered inside the policy. The policy is guaranteed to pay out whenever you die — it never expires.
Whole life solves permanent, ongoing needs that will still exist at age 90. The examples are narrower than the industry usually suggests:
- Estate liquidity for a taxable estate. If you own real estate, a family cottage, or a business with built-in capital gains, your estate owes tax at death on those unrealised gains. Whole life provides cash to pay that tax without forcing your heirs to sell the assets.
- Funding a lifelong dependent.A child with a disability who will require ongoing support no matter when you die is a permanent need — term can't solve it.
- Supplemental retirement cash flow for high-net-worth investors who have already maxed every registered account and want another tax-sheltered savings bucket. This is an optimization, not a foundation.
- Corporate-owned insurance for estate equalisation in family business succession — a specialised use case an advisor should structure.
The common misuse of each
Term sold as permanent protection— a 30-year term policy bought at age 55 "to cover me for life" will lapse at age 85 and leave the buyer uninsured when they need it most. Term is for capped horizons.
Whole life sold as a primary investment vehicle— the internal rate of return on whole life cash value is typically 3–5% over decades. That's fine for the tax-sheltered, guaranteed bucket it's designed to be, but a poor substitute for equities in an RRSP or 401(k). If your registered accounts aren't maxed, whole life usually isn't the next dollar to spend.
The decision framework
Answer two questions:
- Do you have a permanent, ongoing need that will still exist at 85? If yes — estate liquidity, lifelong dependent, specific corporate planning — whole life is a legitimate part of the solution.
- Do you have temporary needs that disappear over time? If yes — mortgage, income replacement, debts — term is the efficient tool.
Many families answer "yes" to both. The right answer is usually a mix: a large term policy covering the temporary need, plus a smaller whole life policy sized specifically to the permanent need. "Buy term and invest the difference" oversimplifies case 1; "whole life is the only permanent solution" oversimplifies case 2.
What an advisor adds
The mistake most people make is buying based on the product, not the need. A good advisor starts with your actual obligations — the mortgage balance, the dependent's years to self-sufficiency, the estate's deemed disposition tax, the business valuation — and works backward to the policy. The policy is the answer; the need is the question.
