Worked Calculations and Buying Checklists
Term 10, 20 or 30? Choosing a term length and laddering life insurance policies
How to pick a term length for life insurance in Canada, why renewals get expensive, and how laddering two or three term policies can cut cost, with worked totals.
Pick a term that lasts at least as long as your biggest need: usually until the mortgage is paid off or the youngest child is independent, whichever is later. For a 35-year-old with young children and a 25-year amortization, that points to a Term 25 or Term 30, or a Term 20 plus a plan for the last years. Avoid relying on renewals: a Term 10 renewed at 45 or 55 typically costs several times its original premium, because the renewal rate is based on your age at renewal. Laddering, meaning buying two or three policies that end at different times, matches coverage to a need that shrinks as debts fall and children grow, and often cuts total premiums by a fifth or more compared with one large policy.
This guide is part of the calculations section that starts with how much life insurance do I need.
How a term policy's premium behaves
| Phase | What happens |
|---|---|
| Level period | Premium fixed for 10, 20, 25 or 30 years, as guaranteed in the contract |
| Renewal | At the end of the level period, the policy renews automatically without medical evidence, at the renewal premium shown in the contract for your attained age |
| Conversion window | You can usually convert to a permanent policy without medical evidence until a stated age |
| Expiry | Coverage ends at a maximum age, often 75 to 85, depending on the product |
The renewal right is insurance on your future health. If you are healthy at renewal, buying a new policy is usually cheaper. If your health has changed, the renewal or conversion right may be the only coverage available.
Comparing three ways to cover a falling need
Illustrative figures: a 36-year-old non-smoker needs about $950,000 today, falling to about $600,000 in 10 years and close to $0 after 20 years, as the mortgage and the children's dependent years end. Premiums are examples, not quotes.
| Strategy | Coverage years 1 to 10 | Coverage years 11 to 20 | Illustrative premiums | Total paid over 20 years |
|---|---|---|---|---|
| A: one $950,000 Term 20 | $950,000 | $950,000 | $85 a month for 20 years | $85 x 240 = $20,400 |
| B: ladder, $600,000 Term 20 + $350,000 Term 10 | $950,000 | $600,000 | $55 + $22 a month, then $55 | ($55 x 240) + ($22 x 120) = $13,200 + $2,640 = $15,840 |
| C: one $950,000 Term 10, renewed at 46 | $950,000 | $950,000 | $38 a month, then a renewal premium of $210 a month | ($38 x 120) + ($210 x 120) = $4,560 + $25,200 = $29,760 |
Strategy B saves $4,560 against A, about 22%, and still covers the need at every point. Strategy C looks cheapest for a decade and is the most expensive overall, unless you could buy a new policy at 46 at healthy rates, which depends on your health then.
How to design a ladder
- Draw your need by year: mortgage balance from your amortization schedule, plus the years of income your family needs (see the needs calculation).
- Identify the floor that lasts longest; buy that amount with the longest term.
- Layer shorter terms for the part that disappears sooner.
- Keep it to two or three policies; each one has a policy fee built into its price.
- Check that every policy is convertible, so you can keep part of it permanently if your health or plans change.
Matching the term to Canadian mortgages
Mortgage amortizations in Canada are commonly 25 years, with 30-year amortizations available on some mortgages, while the rate term is usually five years. Insure the amortization, not the rate term. If you buy a home with a 25-year amortization at 33 and your youngest child turns 22 when you are 52, a Term 20 ending at 53 covers the children but leaves about five years of mortgage. A Term 25 would cover both; alternatively, check your projected balance at year 20, which may be small enough to pay from savings.
Some insurers sell decreasing term, where coverage falls each year. It matches a mortgage more closely, but compare its price with a level ladder: lender mortgage insurance, a related product, is discussed in mortgage insurance versus term life.
When a longer single term is better
- You might add debts later: a level policy keeps spare coverage for a bigger home or another child.
- Your health is likely to change: a family history of heart disease or diabetes makes guaranteed coverage at a fixed price more valuable.
- You want simplicity: one policy, one premium, one beneficiary designation to maintain.
When to consider permanent coverage instead
If part of the need never ends, such as estate tax on a cottage or support for a dependant with a lifelong disability, cover that part with permanent insurance and the rest with term. The comparison of costs is in buy term and invest the difference.
Frequently asked questions
Can I cancel one policy in a ladder early?
Yes. Term policies normally have no cash value and can be cancelled at any time by stopping payment or writing to the insurer. You do not get premiums back.
Is the renewal premium guaranteed?
In most Canadian term policies the renewal premiums are printed in the contract and guaranteed. Some products have adjustable renewal rates; check the wording.
What happens if I become ill during the term?
Nothing changes: the insurer cannot cancel a guaranteed policy because your health changed, as long as premiums are paid and the application was accurate.
Does a longer term mean higher coverage?
No. The term only affects how long the level premium and coverage last. The face amount is a separate choice.
