Quick start
- Open the Canadian Mortgage Calculator.
- Enter the property price, down payment, nominal annual rate, amortization years, and payment frequency.
- Calculate, then check payment, loan amount, loan-to-value, total interest, and payment count.
- If the down payment is under 20%, check official mortgage loan insurance rules before trusting the cash plan.
- Treat the answer as payment math, not a stress-test or lender approval result.
Best uses
Start here if one of these sounds like your job. The examples below show which inputs matter most.
- Estimate a Canadian mortgage payment from price, down payment, rate, amortization, and frequency.
- Compare monthly, biweekly, weekly, and semimonthly payment frequencies.
- See loan-to-value from property price and down payment.
- Check how amortization length changes payment and total interest before a lender quote.
What this calculator is for
The Canadian Mortgage Calculator estimates the base mortgage payment before default insurance, property tax, closing costs, and lender approval. It uses Canadian-style semi-annual compounding, so it is not the same as a quick U.S.-style monthly-rate shortcut.
Use it before comparing mortgage quotes, testing a down payment, checking a biweekly payment, or seeing how much a shorter amortization changes the payment.
What to enter
Canadian mortgage estimates need the price, down payment, nominal annual rate, amortization, and payment frequency to stay together. A small rate or amortization change can move both the payment and total interest.
- Enter the property price and down payment in Canadian dollars.
- Enter the nominal annual mortgage rate as a percent, such as 5.1 for 5.1%.
- Enter the amortization in years, then choose the payment frequency you want to compare.
Example walkthrough
Try the starter example: a $600,000 property, $120,000 down payment, 5.1% rate, and 25-year amortization. The estimate is about $2,819.09 per month, with a $480,000 loan, 80% LTV, and about $365,727.47 in interest.
- For a $600,000 property with $120,000 down, the estimated loan amount is $480,000 and the loan-to-value is 80%.
- At 5.1% over 25 years, the calculator estimates about $2,819.09 per month and about $365,727.47 in total interest.
Formula and steps
In plain language: The calculator subtracts down payment from property price, converts the nominal annual rate through Canadian semi-annual compounding, then calculates the payment for the selected frequency. If the result seems too high or too low, first check whether each field expects a monthly amount, annual amount, dollar value, or percent.
The calculator first turns the nominal annual rate into an effective annual rate using semi-annual compounding. Then it converts that rate to the selected payment period and runs the fixed-payment formula.
How to read the answer
Start with the payment, then check whether it is monthly, biweekly, semimonthly, or weekly. Then read loan amount, LTV, payment count, and total interest so the payment has context.
- The payment is for the selected frequency. A biweekly answer is every two weeks, not a monthly payment.
- Loan-to-value shows the loan amount as a percent of property price. Under 80% LTV usually means a down payment of 20% or more.
- Total interest depends on amortization length and does not include future renewal-rate changes when the term ends.
Common mistakes to avoid
Most bad Canadian mortgage estimates come from forgetting default insurance, mixing monthly and biweekly payments, using the wrong compounding assumption, or treating payment math as lender qualification.
- Do not use a U.S. monthly-compounding mortgage calculator for this exact comparison.
- Do not forget mortgage default insurance if your down payment is under 20%.
- Do not treat this as lender qualification. Canadian lenders can use a stress-test rate that is higher than the contract rate.
- Do not compare payment frequencies without checking whether the lender means regular or accelerated payments.
What to try next
A related tool can help when the mortgage payment is only one part of the home-buying question, such as down payment, another country-specific mortgage style, or a plain loan comparison.
- Use Down Payment Calculator to compare deposit size and loan-to-value.
- Use Mortgage Calculator for a plain U.S.-style mortgage estimate.
Sources and estimate notes
Canada.ca explains mortgage terms, amortization, down payment, and mortgage loan insurance. OSFI explains the minimum qualifying rate stress-test idea, while the Bank of Canada policy-rate page helps separate central-bank rate news from the exact lender rate in your quote.
This calculator still stays simple. It does not add default insurance premiums, check income or debts, approve a mortgage, predict renewal rates, or replace a written lender quote.

FAQ in plain language
When should I use the Canadian Mortgage Calculator?
Use it when you want to test the exact inputs on this page: Estimate a Canadian mortgage payment from price, down payment, rate, amortization, and frequency. Compare monthly, biweekly, weekly, and semimonthly payment frequencies. The result is a check against your assumptions, not proof that a lender, tax app, broker, platform, or provider will use the same number.
What do the main Canadian Mortgage Calculator inputs mean?
Property price means the home price before down payment, closing costs, default insurance premiums, or tax adjustments. Down payment means cash put toward the home price; the calculator subtracts it from price to get the loan amount. Interest rate means the nominal annual mortgage rate entered as a percent, such as 5.1 for 5.1%. Amortization means the years used to spread out the payment estimate, not the shorter mortgage term that may renew earlier. Payment frequency means how often the calculator estimates a payment, such as monthly, biweekly, or weekly.
Why is a Canadian mortgage calculator different?
Canadian mortgage payment math commonly starts from a nominal annual rate with semi-annual compounding. This calculator converts that rate before estimating the payment frequency you choose.
Does this include mortgage default insurance?
No. If the down payment is under 20%, Canadian buyers usually need mortgage loan insurance. This calculator shows the base loan payment before adding that premium, premium tax, or lender-specific rules.
Is amortization the same as the mortgage term?
No. Amortization is the full payoff timeline used for the payment estimate. The mortgage term is the shorter contract period before renewal, often five years or less.
Does the calculator test if I qualify?
No. Canadian lenders use income, debts, credit, property details, and a stress-test rate. The stress test can be higher than the rate used for this payment estimate.
What is the Canadian Mortgage Calculator doing with my numbers?
In plain language: The calculator subtracts down payment from property price, converts the nominal annual rate through Canadian semi-annual compounding, then calculates the payment for the selected frequency. If the result seems too high or too low, first check whether each field expects a monthly amount, annual amount, dollar value, or percent.
