# Mortgage Calculators for Canadian Home Buyers

> Estimate mortgage payments, affordability, insurance, renewal and penalties with Canadian rules like semi-annual compounding for 2026

A Canadian mortgage isn't quite like one in other countries. Fixed rates compound twice a year, terms usually run five years, and you renegotiate the balance at each renewal. Insurance rules and stress tests also limit how much you can borrow, and you'll hit those limits before you ever talk to a seller, so it's smart to know where you stand.

Begin with the [mortgage payment calculator](https://tax-services.ca/calculators/mortgage/mortgage-calculator) to see the regular payment for a given price, rate and amortization.

## What should I check before I buy?

Lenders want a minimum down payment. The [down payment calculator](https://tax-services.ca/calculators/mortgage/down-payment) shows the amount for your price, and if you put down less than 20%, the [mortgage insurance calculator](https://tax-services.ca/calculators/mortgage/cmhc-insurance) adds the premium. Wondering what you can afford? To find a budget, use the [affordability calculator](https://tax-services.ca/calculators/mortgage/mortgage-affordability), then try the [stress test](https://tax-services.ca/calculators/mortgage/mortgage-stress-test) and [pre-approval](https://tax-services.ca/calculators/mortgage/mortgage-pre-approval) tools.

## What if I already have a mortgage?

Extra payments cut interest, as the [prepayment calculator](https://tax-services.ca/calculators/mortgage/mortgage-prepayment) and the [amortization schedule](https://tax-services.ca/calculators/mortgage/mortgage-amortization) show. When your term ends, compare offers with the [renewal calculator](https://tax-services.ca/calculators/mortgage/mortgage-renewal). Breaking a term early can hurt, and you'll want to know by how much before you call the lender, so estimate the [penalty](https://tax-services.ca/calculators/mortgage/mortgage-penalty) first, or test a [refinance](https://tax-services.ca/calculators/mortgage/mortgage-refinance).

There are other ways to borrow. Try the [fixed vs variable comparison](https://tax-services.ca/calculators/mortgage/fixed-vs-variable-mortgage), the [HELOC calculator](https://tax-services.ca/calculators/mortgage/heloc-calculator) or the [commercial mortgage calculator](https://tax-services.ca/calculators/mortgage/commercial-mortgage-calculator).

Results follow 2026 federal lending rules. Your lender's own offer is the figure that counts.

## Which rate should I enter?

Rates move often, so type in the offer you're holding. Lenders may round payments or use their own day-count rules, which means your last payment can differ a little from the schedule, and that's normal.
