Alberta Mortgage Payment Calculator
Not just the mortgage payment. Taxes, insurance, CMHC, cash to close, income needed — the full picture.
Your mortgage payment depends on more than just the rate your bank quotes you. In Canada, all mortgages use semi-annual compounding — not monthly like most online calculators assume. That difference adds up. This calculator uses the correct Canadian formula so the number you see is the number you will actually pay.
Adjust the purchase price, down payment, amortisation period, and interest rate to see your estimated monthly, bi-weekly, or weekly payment. You will also see a full breakdown of principal vs. interest and total interest paid over the life of the mortgage — numbers your bank will not volunteer.

What This Calculator Shows You
Most payment calculators give you principal and interest and stop there. That number is not what leaves your account every month. This one goes further:
- The full monthly cost. Mortgage payment plus property taxes and the other carrying costs that show up whether you budgeted for them or not.
- Your default insurance premium. If you are under twenty percent down, there is a premium, and it changes with how much you put down.
- Cash to close. Different from your down payment, and the number that surprises people at the lawyer's office.
- The stress test check. What you have to qualify at, not what you pay.
- Every down payment option, side by side. This is the most useful part of the tool. Look at it before you decide how much to put down.
What it cannot tell you is the rate you will actually get. The rate depends on your credit, your income, the property, the term, and which lender your file belongs at. Treat the rate field as a test, not a quote.
The Down Payment Ladder, and Why It Is Steeper Than It Looks
Under twenty percent down, your mortgage has to be insured. That premium is a percentage of the mortgage amount and it steps down as your down payment goes up. Roughly speaking it starts around four percent at the minimum five percent down, drops to around three percent once you reach ten percent down, then a little lower again at fifteen percent, and disappears entirely at twenty percent.
Here is the part worth knowing: the biggest single saving is crossing from five percent to ten percent. That first step down the ladder is the steepest one. If you are sitting at seven or eight percent and can reach ten, that is usually the most valuable few thousand dollars you will ever move.
Two more things about that premium. It gets added to your mortgage rather than paid in cash, which means you pay interest on it for the life of the loan. And the rate is the same at all three insurers. Your lender picks the insurer, you do not, and shopping for a cheaper one is not a thing.
Two Ways Alberta Buyers Come Out Ahead
National articles about closing costs are usually written for Ontario buyers, and two of the biggest line items in those articles do not apply here.
No provincial sales tax on the insurance premium. In several provinces, buyers have to write a cheque at closing for sales tax on their mortgage insurance premium, and it cannot be added to the mortgage. Alberta buyers do not have that line item.
No land transfer tax. Alberta charges land title registration fees instead, which are modest by comparison. In some provinces the land transfer tax alone runs into many thousands of dollars at closing.
That is real money staying in your pocket on possession day. It is also why you should not take a closing cost estimate from a national website as gospel. Ours are genuinely lower.
What Most People Get Wrong
They think the payment tells them what they can afford. It does not. The payment tells you what the mortgage costs. Affordability is a separate question involving your income, your other debts, and the stress test. People routinely find a payment that looks comfortable on a home they will not be approved for.
They ignore payment frequency. Switching from monthly to accelerated biweekly means you make the equivalent of one extra monthly payment a year, and it can take years off your amortization. Same budget, no extra effort, just a different setup. It is the closest thing to free money in this business and most people never ask about it.
They assume twenty percent down is always the goal. Usually it is a good goal, since it removes the premium. But not always. Draining every dollar to reach twenty percent and then having nothing for closing costs, moving, or a furnace that quits in November is a bad trade. Sometimes the better move is putting less down and keeping a cushion.
They confuse down payment with cash to close. Your down payment is one part. You also need legal fees, title insurance, an appraisal in some cases, property tax adjustments, and moving costs. Ask for the full number early so it is not a surprise at the lawyer's office.
They forget the payment is not the only thing that changes. Property taxes go up. Insurance goes up. Utilities on a house you own are usually higher than what you paid renting. Budget for the whole cost of ownership, not just the mortgage line.
A Real Scenario
The situation. First time buyers, saved hard, ready to go with a little over five percent down.
The problem. They were about to buy at the bottom of the ladder, which meant the highest insurance premium tier, financed into the mortgage and carrying interest for twenty five years. They had no idea the tiers existed. Nobody had shown them.
What we did. Laid out what the premium looked like at five percent versus ten percent, in dollars, including the interest they would pay on it over the life of the mortgage. Then looked at what it would take to get to ten, including whether a documented gift from family was possible.
The outcome. They closed the gap and bought at the better tier. Same house, meaningfully less cost.
The lesson. Before you decide how much to put down, look at the comparison table on this page. That one screen has saved my clients more money than almost anything else on this website.
Frequently Asked Questions
Q: Do I pay the mortgage insurance premium in cash?
No. In almost every case it is added to your mortgage balance and paid off over the life of the loan, which means you also pay interest on it. In Alberta there is no provincial sales tax on the premium, so unlike buyers in some other provinces you are not writing a separate cheque for it at closing.
Q: What is accelerated biweekly and should I use it?
Your monthly payment is divided in half and paid every two weeks. Because there are twenty six two week periods in a year, you end up making the equivalent of one extra monthly payment annually. That can shave years off your amortization and save a lot of interest, with no real change to your monthly budget. For most people it is worth doing, and it costs nothing to set up.
Q: Should I put twenty percent down if I can?
Often yes, because it eliminates the insurance premium. But not if it leaves you with nothing behind you. Closing costs, moving, and the first repair all come quickly. Sometimes the smarter move is a slightly smaller down payment and a cash cushion. Run both in the comparison above and look at the whole picture.
Q: Why does my payment differ from what the bank quoted?
Usually because one number includes property taxes and the other does not, or because a different rate, amortization, or payment frequency was used. When you compare offers, make sure both are quoting the same things. Principal and interest only versus a full monthly carrying cost are very different numbers.
Q: What is cash to close, and how is it different from my down payment?
Your down payment is the money going toward the purchase price. Cash to close is everything you need available on possession day, which also includes legal fees, title insurance, property tax adjustments, and any other closing items. Alberta buyers catch a break here, because we have no land transfer tax the way several other provinces do.
Q: Can I get a thirty year amortization?
On insured mortgages, thirty year amortizations are available to first time buyers and to buyers of newly built homes, with a small premium surcharge. A longer amortization lowers your payment but increases the total interest you pay over time. On uninsured mortgages the rules differ by lender. Worth discussing rather than assuming.
So What Do You Actually Do?
Play with the down payment comparison above before anything else. That is where the real money is on this page, and it takes about a minute.
Then get a real rate on your actual file, because every number here moves with the rate, and the rate depends on things a calculator cannot see.
