Calgary mortgage calculator
What a Calgary mortgage costs each payment, how long it runs, what it costs in total, and how much sooner it ends if you pay a little more. Built on the Canadian semi-annual convention, so the numbers match what a lender will quote you.
The purchase
20.0% down. The minimum on this price is $31,920.
Lenders qualify you at the higher of this rate plus two points and 5.25% — 6.34% here, a payment of $3,006.08.
The contract length, not the amortization. At the end of it you renew at whatever rates are then available.
Paying it down faster
Most lenders cap annual prepayments at 10–20% of the original principal, and charge a penalty above it. Check your own commitment before planning around a large lump sum.
Where the money goes, year by year
Early payments are almost all interest. The crossover — the year principal finally exceeds interest — is the real shape of an amortized loan, and it is much later than most people expect.

Derived from the figures above, not a lender's statement. A real schedule also depends on your closing date and the lender's rounding.
Why the Canadian number is different
A Canadian fixed-rate mortgage compounds twice a year, not twelve times, even though you pay monthly. That single convention is the reason a calculator written for the American market overstates the payment. On a $500,000 loan at 5% over 25 years the Canadian payment is $2,908.02; run the same loan with monthly compounding and you get $2,922.95. Fifteen dollars a month sounds trivial and comes to more than $4,000 over the amortization.
Accelerated payments are not a trick of the arithmetic
A regular bi-weekly payment is the amortized payment converted to a fortnightly schedule; it finishes at the same time a monthly one would. An accelerated bi-weekly payment is the monthly payment cut in half and paid twenty-six times a year — thirteen monthly payments' worth of money instead of twelve. The shorter amortization is not clever compounding, it is simply paying more. On the benchmark Calgary home that one setting takes about three years off the loan.
What the down payment decides
Below 20% down, a mortgage has to be insured, and the premium runs from 2.80% to 4.00% of the loan depending on how far below you are. It is normally added to the mortgage rather than paid at closing, so you borrow it and pay interest on it for the life of the loan. In Alberta there is no provincial sales tax on that premium; in Ontario there is 8%, payable in cash at closing, which is the kind of detail a generic calculator quietly gets wrong.
The minimum itself is tiered: 5% of the first $500,000, 10% of the portion between $500,000 and $1,500,000, and 20% at $1.5 million and up, where insurance is unavailable altogether. Stretching an insured mortgage to 30 years is available to first-time buyers and on newly built homes, and costs an extra 20 basis points on the premium.
The term is not the amortization
The amortization is how long the loan takes to disappear. The term is how long your rate is locked — five years, usually. At the end of it you renew whatever is left at whatever rates exist then, which is why the calculator shows the balance at the end of the term as prominently as the payment. That number is your actual exposure to rates changing.
What this cannot tell you
A lender qualifies you at the higher of your rate plus two points and 5.25%, so the payment you can afford and the payment you must qualify for are different numbers; both are shown above. Property tax, condo fees, heat and home insurance are not in the payment either — for those, and for the comparison against renting, use the rent versus buy calculator.
