Mortgage Payoff Calculator Canada — Pay Off Early & Save

How it works

$450K Balance, 5.49% Rate, 20 Years Remaining — Impact of Extra Payments

An extra $500/month saves over $92,000 in interest and eliminates 5+ years of payments. Most Canadian lenders allow 15–20% annual prepayment without penalty.

Why Canadian payments differ from American ones

Canadian mortgage interest is compounded semi-annually, not in advance — a requirement of the federal Interest Act — while US mortgages compound monthly. At the same posted rate, the Canadian payment comes out slightly lower.

It is a small difference per month and a large one over an amortization, and it is why a US mortgage calculator gives the wrong answer for a Canadian mortgage. Every calculator on this site’s Canadian pages uses the semi-annual convention.

Term is not amortization

The amortization is how long the mortgage takes to pay off — commonly 25 years. The term is how long your current rate and contract last, usually one to five years. At the end of the term the balance comes due and you renew, at whatever rates exist then.

This is the structural difference from a US 30-year fixed, where the rate is locked for the whole amortization. A Canadian borrower re-prices every few years, which is why what happens at renewal matters as much as the rate you start on.

The stress test you have to clear

Federally regulated lenders must qualify you at the minimum qualifying rate — the greater of your contract rate plus 2% or 5.25% — under OSFI’s Guideline B-20. You are approved on that higher rate, not the rate you will actually pay.

Practically, it means the mortgage you qualify for is smaller than your real payment would suggest. Budgeting off the contract rate and then finding the approval short is one of the most common surprises for first-time buyers.

When mortgage insurance is mandatory

Put down less than 20% and mortgage loan insurance is compulsory, not optional. The premium runs from 2.8% of the loan at 15–19.99% down up to 4% at 5–9.99% down, and it is normally added to the mortgage rather than paid up front — so you pay interest on it for the life of the loan.

Two limits are worth knowing. Insurance is unavailable above $1.5M, so above that price 20% down is effectively mandatory. And in most provinces the PST on the premium must be paid in cash at closing — it cannot be rolled into the mortgage.

Since 15 December 2024, a 30-year insured amortization is available to all first-time buyers, whether resale or new build, and to any buyer of a new build. It lowers the monthly payment and raises total interest, and it carries a 0.2% premium surcharge — worth modelling both ways in the CMHC insurance calculator before choosing.

What the payment does not include

• Land transfer tax, due in cash at closing and charged twice in Toronto, where a municipal tax stacks on the provincial one. See the land transfer tax calculator.
• Property tax, set by your municipality and often collected by the lender alongside the payment.
• Condo fees, which lenders count against your qualifying ratios — commonly at 50% of the monthly fee.
• Legal fees, title insurance and the home inspection, all payable at closing from the same savings as the down payment.
