Calculate Your Canadian Mortgage Payments and Costs

Owning real estate is a common goal for many Canadians. It can be a rewarding investment, but it also brings financial responsibilities that require careful planning. To make sound decisions, you need to estimate mortgage payments, down payments, penalties and other related costs. Online mortgage calculators simplify this process: enter your details and let the tool produce clear numbers you can act on.

The suite of mortgage calculators on MoneySense gives a comprehensive picture of the costs associated with buying and owning a home. They break down key elements such as mortgage payments, taxes, insurance, utilities and maintenance. These tools are designed to help you weigh options, prepare your budget and approach the home-buying process with confidence.

Mortgage affordability calculator

Before you start house hunting, determine how much mortgage you can comfortably afford. A mortgage affordability calculator estimates your borrowing capacity based on your income, regular expenses and debt obligations, helping set realistic budget limits.

Enter your annual income, monthly expenses and any debt payments to see the maximum home price that fits your finances and the corresponding mortgage amount. Many affordability tools also include a “cash needed” section to estimate closing costs, which are an important part of the upfront cash required when buying a home.

If you’re unsure about your down payment amount, combine the affordability calculator with a down payment calculator to get a complete picture of purchase costs. Starting with affordability helps you focus on homes that match your long-term financial goals.

Mortgage down payment calculator

The down payment is the upfront portion of the home price you pay when purchasing a property. The down payment calculator shows how much cash you’ll need for a given purchase price and how that down payment affects your mortgage size and monthly payments.

Your down payment also determines whether you must buy mortgage default insurance and influences your loan-to-value ratio. Enter your intended purchase price and the amount you can put down to see the down payment expressed as a dollar value and as a percentage of the home’s price.

Mortgage payment calculator

A mortgage payment calculator estimates your regular mortgage payments based on purchase price, down payment, interest rate and amortization period. It also shows the total interest paid over the mortgage term, which is essential to understanding the long-term cost of homeownership.

Reliable payment calculators account for additional carrying costs—property taxes, insurance and possible mortgage default insurance—so you can see the full monthly cost of owning the property. Use this tool to compare scenarios, estimate monthly cash flow needs and plan your budget accordingly.

Mortgage insurance calculator

In Canada, buyers who make a down payment under 20% typically must purchase mortgage default insurance, which protects the lender if a borrower defaults. This insurance is different from home insurance, which protects the home itself.

The mortgage insurance calculator estimates the mortgage default insurance premium based on the loan-to-value ratio. Premiums vary with the LTV: lower down payments generally mean higher premiums. Enter the purchase price and down payment to see the estimated insurance cost and how it affects your overall mortgage.

Land transfer tax calculator

Land transfer tax is a one-time fee charged when property ownership transfers. Provincial, territorial and some municipal governments levy this tax, and amounts vary by location and purchase price.

Use a land transfer tax calculator to estimate what you’ll owe when purchasing property in a specific province or municipality. These calculators typically factor in the purchase price, the property’s location and any first-time homebuyer rebates that may reduce or eliminate the tax.

Mortgage refinance calculator

Refinancing can lower your rate, consolidate debt or free up equity, but it usually carries costs for breaking or renegotiating your mortgage. A refinance calculator helps you weigh those costs against the potential savings by estimating breakage penalties, new monthly payments and the equity you can access.

Enter your current mortgage details and proposed new terms. The tool will estimate the penalty for ending your existing mortgage early, show the potential monthly payment under the new rate and calculate available equity—information that helps decide whether refinancing is worthwhile.

Mortgage penalty calculator

Breaking a mortgage early can trigger a prepayment penalty. The amount depends on factors such as your original mortgage terms, remaining balance, interest type and current rates. Fixed-rate mortgages commonly use the greater of an interest rate differential or three months’ interest, while variable-rate mortgages often charge three months’ interest.

A penalty calculator uses your mortgage start date, term length, current balance and rate type to estimate the fee you would owe to break the mortgage early. Understanding this cost is essential before switching lenders or moving to a different mortgage product.

Mortgage renewal calculator

When your mortgage term ends, you can renew with your current lender or negotiate a new deal elsewhere. A renewal calculator compares offers to help you choose the most suitable rate and terms. Input the mortgage amount, location, down payment percentage, amortization, payment frequency and available interest rates to evaluate renewal options.

The tool can also include ongoing costs like utilities, home insurance and condominium fees so you can see the full monthly impact. Using a renewal calculator makes it easier to decide whether to renew or switch lenders when your term expires.

Renting vs buying calculator

Deciding whether to rent or buy requires a careful financial comparison, not just emotion. Rent-vs-buy calculators evaluate a range of variables including purchase price, expected length of stay, opportunity cost of invested funds, maintenance, taxes and fees to determine which option makes more financial sense.

One practical rule of thumb is the “5% rule”: if you can rent for 5% or less of the cost of buying, renting may be the better financial choice. Whatever route you choose, include recurring costs like tenant or home insurance when building your budget.

Next steps after using online calculators

Mortgage calculators are powerful tools for planning, but they provide estimates based on the inputs you supply. Use them to form realistic expectations, compare scenarios and prepare questions for lenders or mortgage brokers. For complex decisions or personalized guidance, consider consulting a mortgage professional or financial advisor who can factor in your full financial picture and long-term goals.
