Ontario mortgage calculators

Six calculators built on the rules Canadian lenders actually apply — semi-annual compounding, the tiered minimum down payment, the published insurance premium bands, the minimum qualifying rate, and current Ontario and Toronto land transfer tax brackets. Every one produces an illustrative estimate, not an approval.

How to use them together

Each one answers a different question at a different stage.

Buyers usually start with the wrong question. The useful sequence is: what range is realistic, what does the monthly commitment look like at the top of that range, how much cash does closing day require, and what would a lender actually say about it. The calculators map onto that order.

What none of them can do is read your documentation. The gap between a calculator result and a lender decision is almost always about how income is calculated, how debt is counted, and which lender policy applies — and that is where a review earns its keep.

A sensible order of operations

  1. 1.Establish the range

    The affordability calculator, using a conservative rate. Write down the number that comes out and treat it as a ceiling, not a target.

  2. 2.Pressure-test the monthly commitment

    The payment calculator at the top of your range. If the payment at that price is uncomfortable, the range is too high regardless of what the ratios allow.

  3. 3.Confirm the down payment plan

    The down payment calculator, to check whether the minimum is within reach and what waiting for a larger one would buy you.

  4. 4.Budget the closing day

    The closing cost calculator, so the cash requirement is known well before you are committed to a date.

  5. 5.Get it reviewed

    A qualification review, where a licensed professional reads your actual documentation and tells you what the file supports.

Before you rely on a result

Calculator questions, answered

Are these calculators accurate?

The arithmetic is built on current Canadian rules — semi-annual compounding, the tiered minimum down payment, the published insurance premium bands and amortization surcharge, the minimum qualifying rate, and current Ontario and Toronto land transfer tax brackets. What a calculator cannot know is how a lender will treat your income, your credit history, the property, or which lender policy fits your file. Treat every result as an illustrative estimate for planning, not an approval.

Which one should I start with?

If you are early and want to know what price range is realistic, start with the affordability calculator. If you have a price in mind and want to understand the monthly commitment, use the payment calculator. If you are close to writing an offer, the closing cost calculator is the one that prevents surprises. They are all designed to be used together rather than in isolation.

Why is the affordability result lower than other calculators give me?

Because it applies the stress test. Canadian lenders qualify you at the greater of your contract rate plus two percentage points or a regulated floor, not at the rate you would actually pay. Calculators that use only your contract rate produce a friendlier number that a lender will not honour.

Is any of this a pre-approval?

No. Nothing on this site is a mortgage application, pre-approval, commitment, rate quote or guarantee of financing. No lender is involved and no credit check occurs. Every result is subject to lender underwriting. When you want a figure you can act on, the qualification review is the next step.

Do you keep what I enter?

The affordability calculator saves your inputs in your own browser so they carry into the purchase-readiness assessment if you choose to start one. Nothing is transmitted to us unless you submit a form. The other calculators do not retain anything after you leave the page.

Every calculator on this site provides an illustrative estimate only and is not a mortgage application, pre-approval, commitment, rate quote or guarantee of financing. Actual qualification depends on lender underwriting, income verification, credit, debt obligations, property details, rate and other factors. Rates, insurance premium schedules, qualifying-rate parameters, land transfer tax rates and rebate rules are set by lenders, insurers and government and can change without notice. These tools do not provide legal, tax or financial advice.

Next step

Turn an estimate into a plan.

Provide your documentation through the qualification review and a mortgage professional will respond within one to two business days with what your file actually supports.
