How Can A Mortgage Affordability Calculator Help Me As A Potential Home Buyer?

A mortgage affordability calculator can help you get an estimate of how much you’re able to borrow. It also allows you to compare different types of mortgages, such as fixed-rate or adjustable-rate, and see which type best suits your needs. With the calculator, you’ll be able to see what kind of monthly payment you’d be making if you chose a certain loan amount, interest rate and length of the loan.


Using this calculator can also help you determine how much money you have to put down for a down payment. Generally, lenders prefer that homebuyers put at least 20% down on their home purchase, but there are options available for those who can’t afford this much. A mortgage affordability calculator can help you to determine what kind of down payment will work best for your budget.


In addition, it can also help you decide if now is the right time for you to buy a home. By entering in your current financial information such as income and debts, the calculator can help you determine if you can comfortably afford a monthly payment for the type of home you want.

What Information Do I Need In Order to Find Out What I Can Afford?

In order to get an accurate picture of what you can afford, you’ll need to gather some basic financial information before using a mortgage affordability calculator.

This includes your annual income, monthly debt payments (such as credit card bills, car payments and student loans), the size of the down payment you plan to make, desired loan length and expected interest rate. You will also need to factor in estimated monthly living costs like property taxes, heating costs, and condo fees (if applicable).

A minimum down payment of five percent is required in Canada, but you will also need to pay mortgage default insurance if you have less than 20% saved. This is important to note because when this insurance is added to the affordability calculator, your maximum mortgage amount will decrease.

Once you have all this information, you can enter it into the calculator and get an estimate of how much of a mortgage payment you can afford. By using an affordability calculator, you’ll be able to make informed decisions about your home-buying journey. You’ll know how much house you can realistically afford so that you don’t take on more debt than you can handle.

What Do Lenders Look At When Determining Mortgage Affordability?

When it comes to the mortgage process, lenders will consider several factors when determining whether or not you’re financially able to pay back a loan. Your household income, credit score and debt service ratios are all important pieces of information that lenders look at when evaluating your application as well as how much money you can afford for a down payment.

Gross Debt Service Ratio (GDSR)

Gross debt service ratio (GDSR) is a measurement used by lenders to determine how much of your monthly income should be allocated towards the mortgage payment. It’s calculated by adding up all of your monthly debt obligations and dividing it by your gross monthly income. The maximum GDSR allowed is usually 39%, which means that no more than 39% of your gross income should be allocated towards debt payments.

Total Debt Service Ratio (TDSR)

Your total debt service ratio (TDSR) is also considered by lenders when determining how much you can borrow. This ratio is calculated by adding up all your monthly expenses and dividing it by your monthly income. The TDSR should not exceed 44%, which means that no more than 44% of your gross income should be put towards all the debt payments you make.

Other Considerations

Lenders will also take a look at how much money you have saved and if you’ve been able to set aside anything that can be used as a down payment on the home. Lastly, they will usually take into consideration your current living situation to make sure that you don’t already have too much of your monthly household income devoted to existing debts.

It’s important to remember that all lenders have different policies and requirements when it comes to mortgage affordability and that this calculator is just an estimate.

By taking the time to use an affordability calculator before you start shopping for a home, you will be able to narrow down what you can and can’t afford right away. It will factor in the above ratios for you and help you better understand your financial situation before meeting with a lender.

What Is The Mortgage Stress Test And How Does Affect Affordability?

In addition to the factors already mentioned, lenders will also take into account the mortgage stress test when evaluating your application. This stress test requires borrowers to prove that they can still afford their mortgage payments even if interest rates were to suddenly increase.

This is an important factor for lenders to consider because it ensures that you’ll be able to keep up with your payments if the market begins to fluctuate.

Using an affordability calculator can help you understand how much house you can realistically afford and what kind of mortgage rate you should be expecting based on your financial situation. It will also allow you to see how much house you can afford at the higher rate you would need to pass in the mortgage stress test.

How Can I Increase My Mortgage Affordability?

If you’re looking for ways to improve your mortgage affordability, there are a few things you can do. If your monthly debt payments are a little high, here are some tips for quickly reducing your debt. Paying off credit cards and other debts will help free up more of your income and make it easier for lenders to approve your application.

Another option is to increase your income. This could be done through a raise or promotion at work, taking on a second job, or investing in rental properties. Increasing your income can help you qualify for a larger loan and make it easier to afford the house of your dreams.

Finally, you can save up more money for a down payment. Lenders like to see that you have a sizeable down payment, as it helps reduce the amount of risk they’re taking and shows them that you’re serious about buying a home.

By using an affordability calculator and taking steps to increase your mortgage affordability, you can feel more confident when applying for a loan and know that you’re getting the best terms possible.

No matter what approach you take to increase your mortgage affordability, it’s important to remember that each lender may have different criteria when it comes to approving a loan. It’s always a good idea to shop around and compare offers from multiple lenders before making a decision. This will help ensure you’re getting the best terms possible for your loan.

Additionally, it’s a good idea to talk to a financial advisor or mortgage broker who can provide expert advice on what steps you should take to make yourself more attractive to lenders and maximize your chances of getting approved for a loan.

You’ll see a Build Your Own affordability scenario. This gives you the ability to enter in a custom down payment amount and if it’s less than 20%, the CMHC Mortgage Default Insurance amount will be calculated for you. You can also select an amortization period lower than 30 years if you want to pay off your mortgage faster than that, and enter in a custom interest rate amount.

This side-by-side affordability comparison is helpful in visualizing how interest rates and down payment amounts can make a huge difference in how much you can afford.
