Term vs whole life: "buy term and invest the difference," examined honestly

The oldest argument in personal finance

"Buy term and invest the difference" has been debated for fifty years. The honest answer is it depends — but the default for most households is term. Here's how to tell which camp you're in.

The case for term

Term costs a small fraction of permanent coverage for the same face amount. That matters because the years you need the most coverage — young kids, a big mortgage, one income carrying a family — are exactly the years money is tightest. Term lets you buy $500,000 or $1,000,000 during those years for the price of a couple of restaurant meals a month, and invest what you'd otherwise have spent on permanent premiums into an RRSP or TFSA.

Over a 20-to-30-year horizon, that invested difference — in low-cost index funds inside registered accounts — has historically outgrown the cash value a whole life policy would have built, while your term coverage handles the "what if I die young" risk. When the term ends, the mortgage is typically gone, the kids are independent, and the investments have grown — so you may not need coverage at all.

The case for permanent

Permanent insurance earns its keep when the need never goes away:

• A lifelong dependant — a child with a disability who will need support after you're gone.
• Estate equalization — leaving a business to one child and an equivalent cash benefit to another.
• Business continuity — funding a buy-sell agreement or key-person coverage.
• Corporate tax efficiency — an incorporated professional funding premiums with lower-taxed corporate dollars and flowing the benefit through the Capital Dividend Account tax-free.
• Final-expense and estate liquidity — guaranteeing cash to cover taxes on death so heirs don't have to sell assets.
• A guaranteed legacy — you will leave a defined tax-free sum, regardless of markets.

For these, "the coverage might expire" is a bug, not a feature — and permanent is the correct instrument.

The numbers, side by side

Illustrative comparison for a healthy 35-year-old buying $500,000 of coverage (figures rounded and illustrative — get real quotes and a par illustration before deciding):

The whole life policy builds a real, guaranteed asset — but the same monthly outlay invested in a low-cost registered portfolio typically ends up larger, and the term already covered the death risk during those 20 years. The permanent policy wins on permanence and certainty, not on return.

Where whole life gets oversold

The classic mis-sale is pitching whole life as your primary investment or "your own bank" before you've filled your registered accounts. Watch for these scripts: "it's tax-free growth" (so is a TFSA, with no insurance costs), "you can borrow against it" (you can, at interest, against your own money), and illustrations that lean heavily on non-guaranteed dividends to make the return look competitive. If someone leads with the investment story rather than a coverage need, be skeptical and ask to see the guaranteed column.

How to decide — a short framework

1. Is the need temporary or permanent? Mortgage and kids are temporary; a disabled dependant or estate-tax bill is permanent.
2. Have you maxed your RRSP and TFSA? If not, registered investing almost always beats insurance-as-investment.
3. Is there a specific job only permanent insurance does? CDA funding, a guaranteed legacy, estate liquidity, a lifelong dependant.
4. Can you afford the permanent premium for life? A lapsed whole life policy can be a poor financial outcome.

Answer those before the product conversation, not during it.

Traps to avoid

• Judging a par whole life policy on its illustrated (not guaranteed) values.
• Buying permanent "for the kids" before the income-earners are adequately covered.
• Surrendering a whole life policy early — front-loaded costs mean poor early cash values.
• Assuming "term is always better" — for a true permanent need it can leave you uninsured at 70.
