Mortgage Insurance vs. Term Life Calculator

What the Mortgage Insurance vs. Term Life Calculator does

Almost every Canadian mortgage comes with an offer of creditor life insurance at the branch or on the closing paperwork, and most borrowers sign up without a clear comparison to what a term life policy would actually cost for the same protection. This calculator builds that comparison directly, using your real mortgage amortization schedule to show exactly how creditor insurance coverage declines over time while quoted premiums generally do not.

It also puts numbers to the single most persuasive fact in this whole comparison: the cost per $1,000 of coverage for creditor insurance rises every year as your balance shrinks against a flat premium, while term life's cost per $1,000 stays exactly where it started. That gap, shown at years 1, 10 and 20, is usually the moment this decision becomes obvious.

• A coverage-over-time chart — the declining creditor balance against level term coverage
• Cost per $1,000 of coverage at years 1, 10 and 20, so the widening gap is explicit
• Total premiums paid over your chosen horizon, for each option
• A plain-language feature comparison: beneficiary, portability, underwriting timing and who controls the payout
• A clear flag on post-claim underwriting — the practical risk most consumers have never heard of

The key variables that move the answer — and how each product actually works

The math here is simpler than most mortgage calculators on this site, but the product mechanics matter as much as the numbers, and they are genuinely different between the two.

• Coverage structure — creditor insurance only ever covers your current outstanding mortgage balance, which falls every year you pay it down. Term life pays the full face amount you selected, undiminished, for as long as the policy is in force.
• Premium behaviour — creditor insurance premiums are generally set at the outset and do not fall as your coverage does, which is exactly what makes the cost per $1,000 of coverage climb every year. Term life premiums are fixed for the whole term you select, level against level coverage.
• Underwriting timing — this is the single biggest practical risk with creditor insurance. Many policies are sold with simplified or no medical underwriting at signing, with full underwriting deferred to the point of a claim — meaning a claim can be reviewed, and potentially denied, based on your health history at the time you took out the mortgage, years after you started paying premiums. Term life is underwritten up front, at application, so you know where you stand before you need the coverage.
• Beneficiary and portability — creditor insurance pays the lender directly and is generally lost or requires reapplication if you switch lenders at renewal. Term life pays whoever you name as beneficiary and stays with you regardless of which lender holds your mortgage.

How this is actually calculated

The creditor insurance coverage curve comes directly from a real Canadian mortgage amortization schedule — your mortgage amount, compounded semi-annually at your rate, amortized over your chosen years. Coverage at any year equals the outstanding balance that year; once the mortgage is paid off, coverage — and, in reality, the premium for it — ends.

Term life coverage is simply held constant at the amount you select for the full length of the term. Cost per $1,000 of coverage is calculated the same way for both products at years 1, 10 and 20: annual premium divided by coverage in thousands. Because creditor insurance coverage falls while the premium generally does not, this figure rises every year; because term life holds both flat, its cost per $1,000 never moves.

Total premiums are summed over your chosen horizon — capped at your amortization length for creditor insurance, since coverage and premiums are assumed to end when the mortgage is paid off. The "excess coverage" figure sums, year by year, how much more coverage term life is providing than creditor insurance would at that same point.

• Creditor coverage at year y = mortgage balance at year y, from the amortization schedule
• Cost per $1,000 = (monthly premium × 12) ÷ (coverage ÷ 1,000)
• Total premiums, creditor = monthly premium × 12 × min(amortization years, term)
• Excess coverage = Σ max(0, term coverage − creditor coverage) across every year

What you get, and the risk most consumers have never heard of

Every output here is meant to be compared side by side with the actual offer in front of you — the form at your lender's branch, or a real term life quote — rather than taken as a final answer on its own.

• Coverage over time — makes the declining nature of creditor insurance visible instead of buried in a policy document.
• Cost per $1,000 of coverage — the number that makes the real cost of creditor insurance concrete, especially by year 10 or 20 of a mortgage.
• Total premiums and net advantage — a straightforward dollar comparison over your chosen horizon.
• Post-claim underwriting flag — the practical risk that most matters if this insurance is ever actually needed, and the reason a lower quoted premium is not automatically the better choice.

Using your results well

Get a real term life quote before declining or cancelling any creditor insurance you already have — this calculator uses an indicative premium, and actual term life pricing depends on full medical underwriting that can move the number in either direction. If you have a health condition that might complicate underwriting, that is a genuine reason creditor insurance's simplified approval could still make sense despite the numbers above, and worth discussing directly rather than deciding from a calculator alone.

What this calculator deliberately does not do is sell you anything. It compares the mechanics of two products honestly so you can walk into that conversation — whether it is with your lender, an insurance advisor, or both — with a clear sense of what each option actually provides.

• Get an underwritten term life quote, not just an indicative one, before making a final decision
• Ask your lender directly whether your creditor insurance is medically underwritten now or at claim time
• If switching lenders, check what happens to your existing creditor insurance before assuming it carries over
• Consider health history and insurability, not just price, if simplified approval genuinely matters to you
