When determining how much home you can afford, one of the most important things to consider is how much your mortgage will cost you each month. Luckily, there’s a quick and easy way to calculate this – and we’ll show you how to calculate your mortgage payment using a Canadian mortgage calculator.

First, we’ll need to establish some parameters. For our purposes, let’s assume want to buy a home that costs $472,000. Seems precise, right? So, why this figure? Well, it was the average cost of a home in Canada in December 2019, according to the Canadian Real Estate Association (CREA).

How much your mortgage payments will cost will depend on the size of the mortgage you take out. And that will depend on the amount of money you put up-front in the form of your down payment.

How much mortgage downpayment do you need?

In Canada, it’s typical for a buyer to put down 5-20% (you can put down more, but not less than 5% with a conventional mortgage lender). 

So, for our example $472,000 home, you could put down 5% (23,600), 10% ($47,200), 15% ($70,800), or 20% ($94,000). Of course, you could put down any percentage from 5-20% (or even more), but writing those figures out would take all day. And you’ve got some mortgage calculations to do. 

And the best way to do that is to use a mortgage payment calculator

First, let’s go with the example using 5% down. 

How to calculate your mortgage payment with a 5% down

As mentioned, for a $472,000 home, a 5% down payment would be $23,600. For our purposes, let’s assume the mortgage will be amortized over 25 years, that you choose a five-year fixed mortgage rate of 2.54% (the current best five year fixed rate available), and that you want to pay your mortgage in monthly installments.

(That’s a lot of assumptions. Don’t worry, though, using a mortgage calculator is super easy and can be modified on the fly within seconds.)

But, back to our example. After inputting all the details into the mortgage calculator, you’ll see that your total monthly mortgage payment will be $2,098.

Keep in mind, though, that because a 5% down payment was chosen, the total mortgage cost (which, in this case, would be $466,336) includes mortgage default insurance. Mortgage default insurance, in this example, is an extra $17,936 over the 25 year amortization, paid out in monthly installments, built into your monthly mortgage payment.

You need mortgage default insurance if you want to purchase with less than 20% down.

How to calculate your mortgage payment with 20% down

Now, let’s assume you have some extra cash for a down payment and choose to put 20% down. Not only would that lower your monthly mortgage costs, but it would also eliminate the need for mortgage default insurance as well.

With 20% down, your new mortgage total would be $377,600 or $1,699 per month. That’s $399 less you’d have to pay per month for your mortgage, compared to if you chose to put 5% down.

When calculating your mortgage payment, keep in mind your monthly budget. You’ll want to make sure your monthly mortgage payments fit within your budget, so you can continue to live the lifestyle you want while paying for your home.

Play around with some numbers and speak to a mortgage broker to get a rate lock, which guarantees your rate for up to 90 days; that protects you in the event rates go up over that span. Don’t worry, though, if they drop you can qualify for the newer, better rate. Getting a rate locked in will also help you more accurately calculate your monthly mortgage payments.

So, there you have it. Quick and easy. Now give it a try yourself with our mortgage affordability calculator

The bottom line

You don’t want to be house poor. You could be unhappy in your home and unable to enjoy life, let alone your dream renovations. Smart money says to buy the most you can afford – because your salary goes up, property prices will go up, and affordability will be easier. But, in today’s day and age, how much you can afford, is up to you. Make sure the price you pay still fits your lifestyle.
