Can you Trust Online Mortgage Calculators?

Dan Caird • May 1, 2024

You’d think an online calculator is a pretty straightforward device, one that you should be able to place your confidence in, and for the most part, they are. Calculators calculate numbers. The numbers are reliable, but how you interpret those numbers, not so much, especially if the goal is mortgage qualification.


If you rely on the numbers from a “What can I afford” or “Mortgage Qualification” calculator without talking to an independent mortgage professional, you’re going to be misinformed.


Don’t be fooled. Even though an online mortgage calculator can help you calculate mortgage payments or help you assess how additional payments would impact your amortization, they’ll never be able to give you an exact picture of what you can afford and how a lender will consider your mortgage application.


While mortgage calculators are objective, mortgage lending isn’t. It’s 100% subjective. Lenders consider your financial situation, employment, credit history, assets, liabilities, the property you are looking to purchase. Then, they will compare that with whatever internal risk profile they are currently using to assess mortgage lending. Simply put, they don’t just look at the numbers.


An online calculator is a great tool to help you run different financial scenarios and help assess your comfort level with different payment schedules and mortgage amounts. However, if you rely on an online calculator for mortgage qualification purposes, you’ll be disappointed.


The first step in the mortgage qualification process is a preapproval. A preapproval will examine all the variables on your application, assess your financial situation, and provide you with a framework to buy a property based on your unique circumstance.


Securing a preapproval comes at no cost to you and without any obligation to buy. It’ll simply allow you the freedom to move ahead with confidence, knowing exactly where you stand. Something a calculator is unable to do.


Please connect anytime if you’d like to talk more about your financial situation and get a preapproval started. It would be a pleasure to work with you.

When you apply for a mortgage, your employment history and status carry a lot of weight. Even if you feel secure in your job, lenders need proof that your income is reliable and will continue. To them, your employment status is one of the strongest indicators of whether you can make your mortgage payments long term. Here’s how lenders typically view different employment situations: Permanent Employment This is the gold standard. Once you’ve passed any probationary period and hold permanent status, lenders see you as a lower risk. It shows that your employer is committed to you, and your income is steady. Probationary Periods If you’re still on probation—usually 3 to 6 months, though sometimes longer—lenders may hesitate. That’s because your employer can end your contract without cause during this period. Once probation is over, you’re considered more secure. That said, context matters. If you’ve worked with the same company for years as a contractor and just transitioned into full-time employment, lenders may accept a letter from your employer confirming that probation is waived. Documentation is key here. Parental Leave Being on or about to take parental leave doesn’t mean you can’t qualify for a mortgage. As long as you have a letter from your employer guaranteeing your position and return-to-work date, lenders can use your regular salary—not your leave income—when assessing your application. Term Contracts This is one of the trickiest categories. Even highly skilled professionals with strong incomes can face challenges here. A term contract has a start and end date, which makes lenders question the stability of your future income. To use term-contract income, lenders generally want to see at least two years of history, or proof that your contract has already been renewed. The more evidence you can show of consistent employment, the stronger your case will be. The Bottom Line If you’re planning to apply for a mortgage, it’s important to understand how your employment status could affect your approval. Whether you’re starting a new job, coming back from leave, or working under contract, lenders want documentation that proves your income is reliable. 📞 If you’ve recently changed jobs or are planning a career shift, let’s connect.
