Why Your Mortgage Insurance Premium Never Goes Down (And What to Do About It)
Why Your Mortgage Insurance Premium Never Goes Down (And What to Do About It)
Nick started noticing something in the third year of his mortgage. His balance was going down, about $12,000 lower than when he started. But his mortgage insurance payment was exactly the same as day one: $76 per month. He called his bank and asked if the premium would drop as his balance decreased. The answer was no. "The premium is fixed based on your original mortgage amount and age at sign-up," the representative explained. Nick did the math and realized he was paying the same amount each month for protection that was worth thousands less. He cancelled within the week.
The Financial Consumer Agency of Canada describes this feature plainly in their educational material: bank mortgage life insurance premiums are typically fixed while coverage declines. It's not a bug in the system. It's how the product is designed.
The Mechanics of Declining Balance Insurance
Here's how it works. When you sign up for bank mortgage insurance, the premium is calculated based on your original mortgage amount and your age at signup. That premium stays fixed for the life of the policy.
But your coverage equals your outstanding mortgage balance at any given time. Every month you make a mortgage payment, your balance drops slightly. So does your coverage. But your premium doesn't.
By year 5 on a typical 25-year mortgage, you've paid off about 5-8% of your original balance. Your coverage has dropped by that same amount. Your premium: unchanged.
By year 10, you've paid off about 15-20%. Coverage down by that much. Premium: unchanged.
By year 20, you might have paid off 40-50% of the mortgage. Coverage is worth roughly half what it started at. Premium: unchanged.
You are paying the same price for something that is worth materially less every single month.
How Much You're Overpaying Over Time
Age 35, $400,000 mortgage, $78/month premium:
| Year | Outstanding Balance | Coverage Worth | Monthly Premium | Cost per $1000 of Coverage |
|---|---|---|---|---|
| 1 | $395,000 | $395,000 | $78 | $0.20 |
| 5 | $375,000 | $375,000 | $78 | $0.21 |
| 10 | $340,000 | $340,000 | $78 | $0.23 |
| 15 | $290,000 | $290,000 | $78 | $0.27 |
| 20 | $225,000 | $225,000 | $78 | $0.35 |
By year 20, you're paying 75% more per dollar of coverage than you were in year one. Same premium, dramatically less value.
Why Banks Design It This Way
The economics favour the insurer. As your mortgage balance decreases, their liability decreases. But revenue stays flat. Over time, the profit margin on each policy increases automatically without any changes required.
A 2021 analysis by the Consumers Council of Canada noted that bank creditor insurance products have among the highest profit margins in the Canadian insurance industry, partly due to the declining balance structure combined with fixed premiums.
The Term Life Alternative
An independent 20-year term life policy for the same starting amount costs about $30 to $40 per month and covers you for the full stated amount for the entire term. If you die in year 1 or year 20, the payout is the same.
Over 20 years, you pay less and get consistent coverage. The cost per $1,000 of coverage doesn't inflate over time because the coverage doesn't shrink.
Some people worry that they'd be "over-insured" in later years when the mortgage is nearly paid off. But excess coverage is rarely a problem. Your family can use the money however they choose: pay off remaining mortgage, replace income, fund education. More is almost always better than less.
What to Do About It
If you currently have bank mortgage insurance, here's the action plan:
- Check your current outstanding balance against what you were originally insured for
- Get a quote for a comparable term life policy at your current age
- If the term life quote is cheaper for equal or better coverage, apply for it
- Cancel the bank insurance once the term life policy is active

The Bottom Line
Your mortgage insurance premium not decreasing is a deliberate feature, not an oversight. Every month you hold bank mortgage insurance, you're paying the same price for less protection. The Canadian insurance market offers better options at lower prices. The only thing standing between you and those savings is inertia.
If your mortgage balance has been dropping for years while your insurance premium hasn't, isn't it time to ask whether that original deal still makes any sense?
