Mortgage life insurance cost depends on two numbers: how much you borrow and how old you are when you apply. Lenders charge a monthly rate per $1,000 of the insured amount, and the rate climbs with each age band. Below is a worked example using one bank's published rates, set beside Instasure term life estimates, so you can see where the money goes.
How much does mortgage life insurance cost?
Lender mortgage life insurance costs a monthly rate per $1,000 of your mortgage, set by your age band when you apply. At CIBC's published single-coverage rates (July 2025), a $300,000 mortgage costs $42 a month at ages 30 to 35, $63 at 36 to 40 and $93 at 41 to 45, before any sales tax.
That's the price of creditor insurance, the optional coverage your lender offers when you sign or renew. It pays the balance owing to the lender if you die. A personal term policy works differently, and the comparison below shows why the two prices can be far apart.
How lenders calculate mortgage life insurance premiums
The bank mortgage insurance premium calculation is simple. CIBC's certificate of insurance spells it out: your monthly life premium equals the initial insured amount divided by 1,000, times the premium rate for your age, plus applicable taxes. TD and RBC also publish their rates per $1,000, by age band at application.
Three details drive the cost:
- The amount. CIBC applies the rate to the initial insured amount, and RBC to the initial mortgage balance. The premium doesn't follow your balance down.
- Your age band. The rate depends on your age at application, in bands of about five years.
- Discounts. CIBC builds a tiered discount into premiums when the initial insured amount is over $300,000. TD reduces its rate by 15% on the part of the insured balance between $150,000 and $500,000.
Mortgage life insurance cost by age
Here are CIBC's single-coverage life rates, as published in its product summary dated July 2025. The monthly premiums are our arithmetic from those rates.
| Age at application | Monthly rate per $1,000 | Monthly premium per $100,000 | Monthly premium on $300,000 |
|---|---|---|---|
| Under 30 | $0.08 | $8 | $24 |
| 30 to 35 | $0.14 | $14 | $42 |
| 36 to 40 | $0.21 | $21 | $63 |
| 41 to 45 | $0.31 | $31 | $93 |
| 46 to 50 | $0.46 | $46 | $138 |
| 51 to 55 | $0.59 | $59 | $177 |
| 56 to 60 | $0.76 | $76 | $228 |
| 61 to 64 | $1.03 | $103 | $309 |
CIBC single-coverage life rates per $1,000 of initial insured amount, product summary 13031RE (2025/07). Premiums are before provincial sales tax, where it applies. Amounts over $300,000 get a tiered discount. Check the rate in your own certificate, because lenders update their documents.
The rate more than doubles between the 30 to 35 band and the 41 to 45 band. Applying five years later can cost far more than the extra five years of age suggests.
Age bands and premium jumps at renewal
Your rate is locked to your age band when you apply. TD and RBC both say your rate won't rise during the mortgage, as long as the balance doesn't increase and you don't refinance.
The jump comes when you apply again. Switching lenders, refinancing or borrowing more usually means new coverage at your current age. Here's an illustration using CIBC's rates:
- You insure $300,000 at age 35. The premium is $42 a month.
- Five years later, at 40, about $263,000 is left on a 25-year mortgage at 4.5%.
- You switch lenders and insure that $263,000 at the 36 to 40 rate of $0.21. The premium is about $55 a month.
You'd pay more to cover a smaller debt. A new lender would use its own rates, but the pattern is the same: a higher age band at every new application. Before you renew, see our guide to mortgage insurance vs life insurance for what changes when you switch.
Single vs joint coverage pricing
Couples who both sign the mortgage can usually insure both lives. Each lender prices it differently:
- CIBC takes 15% off each person's premium when two people are insured for the same coverage on the same mortgage.
- TD applies a 20% discount to each person's premium when more than one person is insured on the same mortgage.
- RBC publishes a separate joint rate, based on the age of the older person.
With CIBC's rates, two 38-year-olds insuring $300,000 would each pay $63 less 15%, or $53.55. That's $107.10 a month for the couple, before tax.
Joint creditor coverage pays the mortgage once. In Instasure's model, two personal $300,000 Term 30 policies at age 38 are about $24.50 to $35 a month for the woman and $31.50 to $44.50 for the man (non-smokers, example profiles, October 2026). Each policy pays a full benefit.
Lender premium vs term life: worked example
This example compares mortgage life insurance vs term cost for a $300,000 mortgage with a 25-year amortization. The lender column uses CIBC's published rates. The term columns are Instasure estimates for $300,000 of 30-year term, non-smokers in good health, as of October 2026.
| Age at application | Lender premium (CIBC rate on $300,000) | Personal Term 30, female non-smoker | Personal Term 30, male non-smoker |
|---|---|---|---|
| 35 | $42 | $20.50 to $29 | $26 to $37 |
| 40 | $63 | $27.50 to $39.50 | $35.50 to $50.50 |
| 45 | $93 | $41.50 to $59 | $54 to $76.50 |
| 50 | $138 | $65.50 to $93 | $85.50 to $121 |

The monthly gap is only half the story. Look at what each premium buys over time, using an illustrative 4.5% rate held for 25 years:
| Year of the mortgage | Balance left (lender payout) | Term life payout | Lender cost per $1,000 of coverage, age 35 |
|---|---|---|---|
| Start | $300,000 | $300,000 | $0.14 |
| Year 5 | About $263,000 | $300,000 | About $0.16 |
| Year 10 | About $218,000 | $300,000 | About $0.19 |
| Year 15 | About $161,000 | $300,000 | About $0.26 |
| Year 20 | About $89,000 | $300,000 | About $0.47 |
Why is mortgage insurance so expensive?
The premium stays at $42 while the payout shrinks. By year 20, you're paying more than three times the starting rate for each $1,000 of coverage you actually have. The term policy keeps paying $300,000 to the people you name.
Term isn't cheaper for everyone. Smokers pay much more for personal coverage. In the same model, a 40-year-old male smoker pays about $82 to $116.50 a month for $300,000 of Term 30. That's above the $63 lender premium, so health and smoking status can flip the result. If you plan to clear the mortgage in about 20 years, Term 20 costs less: about $24 to $34 a month for a 40-year-old male non-smoker.

Taxes on creditor premiums
Lender rate tables are published before tax. CIBC's formula adds applicable taxes to the premium. TD's product guide says its rates don't include provincial sales taxes, if applicable.
So the premium on your statement may be higher than the rate table suggests. Before you compare, take the after-tax amount from your mortgage statement or certificate. Then ask how tax applies to each option in your province.
Mortgage protection insurance rates by province
Lenders can publish different documents for different provinces. CIBC, for example, has a separate product summary for Quebec residents. Insurance in each province is overseen by its own regulator.
- Ontario: compare mortgage life insurance Ontario options with a licensed advisor. FSRA regulates insurance in the province.
- British Columbia: see mortgage life insurance BC. BCFSA is the regulator.
- Alberta: see mortgage life insurance Alberta. The Superintendent of Insurance oversees the market.
- Quebec: our mortgage life insurance Quebec page is for information only. The AMF regulates insurance there, and advisor service isn't available in Quebec yet.
How to compare your own numbers
You can check your own mortgage life insurance cost with your latest mortgage statement.
- Find three numbers: the monthly premium, the insured amount and the tax. They're on your statement or insurance certificate.
- Work out your rate. Divide the premium before tax by the insured amount in thousands. Compare the result with your lender's table.
- Work out your real cost. Divide the same premium by your current balance in thousands. That's what you now pay per $1,000 of actual coverage.
- Price personal term. Get an estimate for your balance, plus any buffer for other debts or income.
- Compare couples' options. Price joint lender coverage against two separate policies.
- Keep coverage in place. Don't cancel the lender's insurance until a replacement is approved and in force.

Michael's take
As a planner, I look at the cost per $1,000 of coverage you actually have, not the monthly premium. A level premium on a shrinking balance quietly gets more expensive every year. My rule of thumb is to price both options at the start, then again at each renewal, when the lender's coverage is easiest to replace.
I also think of the mortgage as one line in the family's plan, not the whole plan. A personal policy sized to the mortgage plus a buffer can cover the house and give your family room to breathe. If your health makes personal coverage expensive or hard to get, lender coverage may still have a place. Just keep it until any replacement is approved and in force.
