GDS/TDS Ratios Explained

Marci Deane • April 17, 2024

One of the major qualifiers lenders look at when considering your application for mortgage financing is your debt service ratios.


Now, before we get started, if you prefer to have someone walk through these calculations with you, assess your financial situation, and let you know exactly where you stand, let’s connect. There is no use in dusting off the calculator and running the numbers yourself when we can do it for you!


However, if you’re someone who likes to know the nitty-gritty of how things work instead of simply accepting that's just the way it is, this article is for you. But be warned, there are a lot of mortgage words and some math ahead; with that out of the way, let’s get started!

 

“Debt servicing” is the measure of your ability to meet all of your financial obligations. There are two ratios that lenders examine to determine whether you can debt service a mortgage.


The first is called the “gross debt service” ratio, or GDS, which is the percentage of your monthly household income that covers your housing costs. The second is called the “total debt service” ratio, or TDS, which is the percentage of your monthly household income covering your housing costs and all your other debts.


GDS is your income compared to the cost of financing the mortgage, including your proposed mortgage payments (principal and interest), property taxes, and heat (PITH), plus a percentage of your condo fees (if applicable).


Here’s how to calculate your GDS.


Principal + Interest + Taxes + Heat / Gross Annual Income


Your TDS is your income compared to your GDS plus the payments made to service any existing debts. Debts include car loans, line of credit, credit card payments, support payments, student loans, and anywhere else you’re contractually obligated to make payments.


Here’s how to calculate your TDS.


Principal + Interest + Taxes + Heat + Other Debts / Gross Annual Income


With the calculations for those ratios in place, the next step is to understand that each lender has guidelines that outline a maximum GDS/TDS. Exceeding these guidelines will result in your mortgage application being declined, so the lower your GDS/TDS, the better.


If you don’t have any outstanding debts, your GDS and TDS will be the same number. This is a good thing!


The maximum ratios vary for conventional mortgage financing based on the lender and mortgage product being offered. However, if your mortgage is high ratio and mortgage default insurance is required, the maximum GDS is 39% with a maximum TDS of 44%.


So how does this play out in real life? Well, let’s say you’re currently looking to purchase a property with a payment of $1700/mth (PITH), and your total annual household income is $90,000 ($7500/mth). The calculations would be $1700 divided by $7500, which equals 0.227, giving you a gross debt service ratio of 22.7%.


A point of clarity here. When calculating the principal and interest portion of the payment, the Government of Canada has instituted a stress test. It requires you to qualify using the government's qualifying rate (which is higher), not the actual contract rate. This is true for both fixed and variable rate mortgages.


Now let’s continue with the scenario. Let’s say that in addition to the payments required to service the property, you have a car payment of $300/mth, child support payments of $500/mth, and between your credit cards and line of credit, you’re responsible for another $700/mth. In total, you pay $1500/mth. So when you add in the $1700/mth PITH, you arrive at a total of $3200/mth for all of your financial obligations. $3200 divided by $7500 equals 0.427, giving you a total debt service ratio of 42.7%.


Here’s where it gets interesting. Based on your GDS alone, you can easily afford the property. But when you factor in all your other expenses, the TDS exceeds the allowable limit of 42% (for an insured mortgage anyway). So why does this matter? Well, as it stands, you wouldn’t qualify for the mortgage, even though you are likely paying more than $1700/mth in rent.


So then, to qualify, it might be as simple as shuffling some of your debt to lower payments. Or maybe you have 10% of the purchase price saved for a downpayment, changing the mortgage structure to 5% down and using the additional 5% to pay out a portion of your debt might be the difference you need to bring it all together.


Here’s the thing, as your actual financial situation is most likely different than the one above, working with an independent mortgage professional is the best way to give yourself options. Don’t do this alone. Your best plan is to seek and rely on the advice provided by an experienced independent mortgage professional. While you might secure a handful of mortgages over your lifetime, we do this every day with people just like you.


It’s never too early to start the conversation about mortgage qualification. Going over your application and assessing your debt service ratios in detail beforehand gives you the time needed to make the financial moves necessary to put yourself in the best financial position.


So if you find yourself questioning what you can afford or if you want to discuss your GDS/TDS ratios to understand the mortgage process a little better, please get in touch. It would be a pleasure to work with you, we can get a preapproval started right away.

Paying Off Your Mortgage As Quickly As Possible

By Marci Deane • April 23, 2025
Being a home owner is excellent, having a huge mortgage isn’t. So, if you have a mortgage that you’re looking to get rid of as quickly as possible, here are four things you should consider doing. Accelerate your payments Making the change from monthly payments to accelerated bi-weekly payments is one of the easiest ways you can make a difference to the bottom line of your mortgage. Most people don’t even notice the difference or increased payment. A traditional mortgage with monthly payments splits the amount owing annually into 12 equal payments. Accelerated biweekly is simply taking a regular monthly payment and dividing it in two, but instead of making 24 payments, you make 26. The extra two payments accelerate the paying down of your mortgage. Increase your regular mortgage payments Chances are, depending on the terms of your existing mortgage, you can increase your regular mortgage payment by 10-25%. Alternatively, some lenders even offer the ability to double-up your mortgage payments. These are great options as any additional payments will be applied directly to the principal amount owing on your mortgage instead of a prepayment of interest. Make a lump-sum payment Depending on your lender and your mortgage product, you should be able to put down anywhere from 10-25% of the original mortgage balance in a bulk payment. Some lenders are particular about when you can make these payments; however, you should be eligible if you haven’t taken advantage of a lump sum payment yet this year. Making a lump-sum payment is a great option if you’ve come into some money and you’d like to apply it to your mortgage. As this will lower your principal amount owing on the mortgage, it will reduce the amount of interest charged over the life of the mortgage. Review your options regularly As your mortgage payments debit from your bank account directly, it’s easy to put your mortgage on auto-pilot and not think twice about it until your term is up for renewal. Unfortunately, this removes you from the driver's seat and doesn’t allow you to make informed decisions about your mortgage or keep up to date with market conditions. So let’s talk about an annual mortgage review. Working through an annual mortgage review with an independent mortgage professional is beneficial as there may be opportunities to refinance your mortgage and lower your overall cost of borrowing. By reviewing your mortgage at least once a year, you can be sure that you’ve always got the best mortgage for you! There is no cost involved here, just a quick assessment and peace of mind. If you’ve got questions about your existing mortgage or want to compare your mortgage to options available today, please connect anytime. It would be a pleasure to work with you.

Bank of Canada Rate Announcement Apr 16th, 2025

By Marci Deane • April 16, 2025
Bank of Canada holds policy rate at 2¾%. FOR IMMEDIATE RELEASE Media Relations Ottawa, Ontario April 16, 2025 The Bank of Canada today maintained its target for the overnight rate at 2.75%, with the Bank Rate at 3% and the deposit rate at 2.70%. The major shift in direction of US trade policy and the unpredictability of tariffs have increased uncertainty, diminished prospects for economic growth, and raised inflation expectations. Pervasive uncertainty makes it unusually challenging to project GDP growth and inflation in Canada and globally. Instead, the April Monetary Policy Report (MPR) presents two scenarios that explore different paths for US trade policy. In the first scenario, uncertainty is high but tariffs are limited in scope. Canadian growth weakens temporarily and inflation remains around the 2% target. In the second scenario, a protracted trade war causes Canada’s economy to fall into recession this year and inflation rises temporarily above 3% next year. Many other trade policy scenarios are possible. There is also an unusual degree of uncertainty about the economic outcomes within any scenario, since the magnitude and speed of the shift in US trade policy are unprecedented. Global economic growth was solid in late 2024 and inflation has been easing towards central bank targets. However, tariffs and uncertainty have weakened the outlook. In the United States, the economy is showing signs of slowing amid rising policy uncertainty and rapidly deteriorating sentiment, while inflation expectations have risen. In the euro area, growth has been modest in early 2025, with continued weakness in the manufacturing sector. China’s economy was strong at the end of 2024 but more recent data shows it slowing modestly. Financial markets have been roiled by serial tariff announcements, postponements and continued threats of escalation. This extreme market volatility is adding to uncertainty. Oil prices have declined substantially since January, mainly reflecting weaker prospects for global growth. Canada’s exchange rate has recently appreciated as a result of broad US dollar weakness. In Canada, the economy is slowing as tariff announcements and uncertainty pull down consumer and business confidence. Consumption, residential investment and business spending all look to have weakened in the first quarter. Trade tensions are also disrupting recovery in the labour market. Employment declined in March and businesses are reporting plans to slow their hiring. Wage growth continues to show signs of moderation. Inflation was 2.3% in March, lower than in February but still higher than 1.8% at the time of the January MPR. The higher inflation in the last couple of months reflects some rebound in goods price inflation and the end of the temporary suspension of the GST/HST. Starting in April, CPI inflation will be pulled down for one year by the removal of the consumer carbon tax. Lower global oil prices will also dampen inflation in the near term. However, we expect tariffs and supply chain disruptions to push up some prices. How much upward pressure this puts on inflation will depend on the evolution of tariffs and how quickly businesses pass on higher costs to consumers. Short-term inflation expectations have moved up, as businesses and consumers anticipate higher costs from trade conflict and supply disruptions. Longer term inflation expectations are little changed. Governing Council will continue to assess the timing and strength of both the downward pressures on inflation from a weaker economy and the upward pressures on inflation from higher costs. Our focus will be on ensuring that Canadians continue to have confidence in price stability through this period of global upheaval. This means we will support economic growth while ensuring that inflation remains well controlled. Governing Council will proceed carefully, with particular attention to the risks and uncertainties facing the Canadian economy. These include: the extent to which higher tariffs reduce demand for Canadian exports; how much this spills over into business investment, employment and household spending; how much and how quickly cost increases are passed on to consumer prices; and how inflation expectations evolve. Monetary policy cannot resolve trade uncertainty or offset the impacts of a trade war. What it can and must do is maintain price stability for Canadians. Information note The next scheduled date for announcing the overnight rate target is June 4, 2025. The Bank will publish its next MPR on July 30, 2025. Read the April 16th, 2025 Monetary Report

Market Update: Navigating Economic Uncertainty in BC's Housing Market

By Marci Deane • April 14, 2025
Market Update: Navigating Economic Uncertainty in BC's Housing Market Economic Outlook from Brendan Ogmundson, CMBA-BC Conference (Following is a summary of my notes taken during Brendan’s live presentation on Tuesday April 8, 2025)  The current economic landscape is characterized by unprecedented uncertainty, according to economist Brendan Ogmundson's recent presentation at the CMBA-BC Conference. His analysis, titled "Stuck Between Stations," highlights several key factors influencing BC's housing market and broader economic outlook. Housing Market Trends Uncertainty has reached record highs—exceeding even 2020 levels—with a striking 600% increase in Canadians reporting concerns about job security. This uncertainty is directly impacting housing market decisions, particularly home buying intentions. The housing inventory situation is evolving rapidly: Listings are accumulating steadily Total active listings across the province are approaching 40,000-45,000 units Completed but unsold new inventory has reached an all-time high These inventory trends are expected to slow housing starts over the next 1-2 years. Current forecasts suggest housing prices will likely remain flat or potentially decrease in the near term. Financial Stability Despite these challenges, BC homeowners appear to be weathering the economic storm relatively well for now. Mortgage arrears and bankruptcies remain at historically low levels, though this represents an ongoing risk worth monitoring. Interest Rate Outlook The bond market continues to experience significant volatility, which is likely to persist in the coming weeks. As a result, lenders are expected to maintain current fixed rate offerings. The Bank of Canada is anticipated to implement one more rate cut, though timing remains uncertain due to inflation concerns related to emerging trade tensions. Ogmundson noted that substantial rate cuts would require a dramatic increase in unemployment—to approximately 8%—which is not the current baseline expectation. Additionally, slowing population growth combined with already poor productivity metrics is expected to reduce Canada's potential GDP growth from 2% to 1.5%. These factors may lead to a new neutral interest rate around 2.25%, with the April Monetary Policy Report potentially confirming a lowered neutral rate. Trade Tensions and Tariffs A significant portion of the presentation addressed the impact of escalating trade tensions, particularly with China. The effective tariff rate with China has now exceeded 40%, creating mechanical price increases throughout supply chains. These tariffs are projected to: Lower economic growth Increase prices by at least 2.3% Reduce disposable income by approximately $3,000 per US household The presentation characterized the potential economic contraction as a "Trumpcession," noting that recent trade policies resemble 18th-century mercantilism with its zero-sum mentality of maximizing exports while minimizing imports. Impact on British Columbia The effects of these economic headwinds will not be uniform across BC, with northern regions potentially facing greater challenges. Economic modeling suggests provincial unemployment could rise above 7%, compared to a baseline of 5% without trade tensions. As we continue to monitor these economic developments, maintaining flexibility and caution in financial and investment decisions will be crucial in navigating this period of heightened uncertainty.
