关于Canadian mortgage calculator

Canadian fixed-rate mortgages compound interest twice a year. The Interest Act (section 6) requires a blended-payment mortgage to state its rate "calculated yearly or half-yearly, not in advance", so 5% means 2.5% every six months, or 5.0625% a year effective. Each payment uses the matching rate per period, for example (1.025)^(1/6) − 1 per month.

With the defaults, a 600,000 home with 10% down needs a CMHC premium of 3.10%, or 16,740, added to the 540,000 loan; at 4.5% over 25 years the 556,740 mortgage costs 3,081.41 a month. The Financial Consumer Agency of Canada's table gives 1,744.81 a month for 300,000 at 5% over 25 years, which this calculator reproduces.

Accelerated bi-weekly payments, half the monthly payment every two weeks, add the equivalent of one monthly payment a year. On that 300,000 mortgage they end the loan in 21.5 years and save 36,261.51 of interest.

常见问题

Why are Canadian mortgages compounded semi-annually?

Section 6 of the Interest Act requires a mortgage with blended payments to state its rate calculated yearly or half-yearly, not in advance, and fixed rates are quoted with half-yearly compounding. A 5% rate is then 5.0625% effective a year instead of 5.1162% with monthly compounding. On 300,000 over 25 years the payment is 1,744.81 a month rather than 1,753.77.

What is the minimum down payment in Canada?

5% of the price up to 500,000; 5% of the first 500,000 plus 10% of the rest up to 1.5 million; and 20% at 1.5 million or more, where mortgage insurance is not available (Financial Consumer Agency of Canada). A 600,000 home needs at least 25,000 + 10,000 = 35,000. With less than 20% down you typically need mortgage default insurance.

How much is CMHC mortgage insurance?

CMHC charges a one-time premium on the loan: 2.80% at 80.01% to 85% loan-to-value, 3.10% up to 90% and 4.00% up to 95% (4.50% with a borrowed down payment). Amortizations over 25 years add 0.20 points. The premium is usually added to the mortgage; Ontario, Quebec and Saskatchewan charge sales tax on it, payable in cash. At 94.17% LTV on 565,000 the premium is 22,600.

Can you get a 30-year mortgage in Canada?

Yes. Since December 15, 2024, an insured mortgage (under 20% down) can be amortized over 30 years if a borrower is a first-time buyer or the home is newly built (Department of Finance); others are capped at 25 years. With 5% down on 500,000 at 4.5%, 30 years costs 2,495.61 a month against 2,734.16 over 25 years, but 77,224.44 more interest.

How much do accelerated bi-weekly payments save?

Paying half the monthly payment every two weeks makes 26 half-payments, or 13 monthly payments, a year. On 300,000 at 5% over 25 years, accelerated bi-weekly payments of 872.41 end the mortgage in 21.5 years and save 36,261.51 of interest; accelerated weekly payments of 436.20 save 36,673.39. Regular bi-weekly payments, set to last 25 years, save only 579.95.
