Mortgage calculators, done the Canadian way.

Nine calculators covering the questions that actually come up — what you can carry, what closing really costs, what breaking a mortgage would take. Open the one you need, run it as many times as you like, and no one asks for your details.

The Calculators

Nine calculators, one tool

Move between them without losing your numbers. Built by us, on Canadian rules — fixed mortgages compound semi-annually here, the way they actually do, the land transfer tax knows every province and territory, and a break penalty is worked the way your lender works it.

Loading the calculators…

Estimates only. Figures are illustrative, assume Canadian semi-annual compounding on fixed-term mortgages, and are subject to final lender approval and terms. Not an approval and not a guarantee of pricing.

A number is a starting point, not an answer. These will tell you what a payment works out to. They can’t tell you whether the term is structured properly, what breaking it early would cost, or how it sits against everything else you’re planning. That part needs a conversation, and it costs nothing to have one.
Which One

Where to start, depending on where you are

If you’re buying

  • Start with AffordabilityFind a realistic price range before you fall for a listing above it.
  • Then the Purchase CalculatorThe full cash you need at closing, not just the down payment.
  • Then Land Transfer TaxThe line item that surprises Ontario buyers most, especially in Toronto.
  • Rent vs Buy if you’re undecidedRun it honestly. Sometimes renting wins, and that’s a real answer.

If you already own

  • Mortgage Amount firstTwo or three amounts side by side, so you can see what another $20,000 actually costs you.
  • Compare Options for a decisionMore down or a smaller house, answered in one table rather than two separate runs.
  • Rental Cash Flow if you hold propertyRent in, costs out, and the one figure a rental actually pays its owner.
  • Break or Stay before you commitThe penalty weighed against what the change is worth, before you sign anything.
Why Canadian math matters. Fixed-term Canadian mortgages compound semi-annually, not monthly. A calculator built for the United States applies the wrong formula and will quietly hand you a payment that’s out by a meaningful amount over a full amortization. Everything on this page uses the Canadian convention.

Common Questions

Questions about the calculators

Are these accurate for Canadian mortgages?

They use Canadian conventions, which matters more than people realise. Fixed-term Canadian mortgages compound semi-annually, not monthly, so a calculator built for the United States will give you the wrong payment. Land transfer tax is calculated on Ontario brackets, with the Toronto municipal charge and first-time buyer rebates handled separately.

Is what the calculator tells me an approval?

No. Every figure is an illustrative estimate. A real approval depends on a lender assessing your income, credit, down payment and the property itself, and the final terms come in writing from that lender. Use these to plan and to sanity-check — not as a commitment.

Why does affordability give a lower number than my bank did?

Usually the stress test, or debt servicing ratios being applied differently. Lenders assess GDS and TDS with their own policies on things like rental income, self-employed income and existing debts, and those policies differ from lender to lender. That variation is exactly why comparing across lenders is worth doing.

Do I need to give my personal information?

No. Every calculator here runs without an application, without a credit check and without contacting anyone. Use them as many times as you like.

Which calculator should I start with?

If you’re buying, start with affordability to find a realistic price range, then the purchase calculator for what the home costs a month, then closing costs for the full cash needed. If you already own, start with break or stay if you’re weighing a change, or mortgage amount to sanity-check a renewal offer.

Can you run these numbers with me?

Yes, and that’s usually the more useful conversation. A calculator answers the question you thought to ask. A conversation catches the ones you didn’t — how the term is structured, what a penalty would cost if plans change, and how the mortgage fits alongside everything else you’re planning.
