How Mortgage Payments Are Calculated

A mortgage payment is primarily determined by three factors: the amount borrowed, the interest rate, and the amortization period.

Mortgage Principal

The principal is the amount financed after subtracting the down payment from the purchase price, before considering any additional amounts that may be added to the mortgage.

Interest Rate

The mortgage interest rate affects how much of each payment goes toward interest rather than reducing the principal.

Amortization

The amortization period is the theoretical amount of time required to repay the mortgage in full if the interest rate and payment structure remained unchanged.

Monthly vs. Biweekly Mortgage Payments

Mortgage lenders can offer several payment frequencies. The payment frequency affects when payments are made and, depending on the structure, how quickly the mortgage balance declines.

Monthly

A monthly mortgage normally involves 12 payments per year.

Biweekly

A standard biweekly schedule normally involves 26 payments per year and is calculated using the equivalent biweekly payment required for the selected amortization.

Accelerated Biweekly

An accelerated biweekly payment is commonly calculated as one-half of the regular monthly payment, paid every two weeks. Because 26 half-payments are made each year, this is equivalent to approximately 13 monthly payments instead of 12 and can reduce the mortgage balance faster.

The Mortgage Payment Is Not the Entire Housing Cost

Property taxes, home insurance, utilities, condominium fees, maintenance, repairs, and other ownership expenses can materially increase the amount required each month.

Use the optional housing-cost fields in the calculator to build a more realistic monthly budget rather than evaluating affordability based only on the mortgage payment.

Mortgage Term vs. Amortization

A mortgage term and mortgage amortization are different.

The term is the period during which a particular mortgage agreement, interest rate, and set of conditions applies. The amortization is the longer period over which the mortgage is scheduled to be fully repaid.

For example, a mortgage may have a five-year term but a 25-year amortization. At the end of the term, a remaining balance will normally still exist and the mortgage may need to be renewed, refinanced, transferred, or paid out.

Mortgage Calculator FAQ

Does this calculator include mortgage default insurance?

No. The calculator subtracts the entered down payment from the purchase price to estimate the mortgage principal. If a mortgage default insurance premium is applicable and financed as part of the mortgage, the actual mortgage amount and payment may be higher.

Does a longer amortization lower the mortgage payment?

Generally, extending the amortization lowers the required periodic payment because repayment is spread over more time. However, a longer amortization can also increase the total interest paid if other factors remain unchanged.

What is accelerated biweekly?

Accelerated biweekly payments are commonly equal to one-half of the monthly mortgage payment and are made every two weeks. This results in 26 half-payments per year, approximately equivalent to making one additional monthly payment annually.

Does this calculator determine whether I qualify for a mortgage?

No. Mortgage qualification can involve income, debt obligations, credit history, down payment, property characteristics, lender underwriting, mortgage-insurance requirements, the mortgage stress test, and other criteria.

Why might my lender’s payment be different?

A lender’s calculation can differ because of mortgage type, compounding methodology, payment frequency, financed insurance premiums, lender-specific terms, rounding, rate discounts, or other contractual factors.

Are property taxes included in my mortgage payment?

Not necessarily. Some lenders collect property taxes with mortgage payments while others require the homeowner to pay the municipality directly. The calculator displays estimated property taxes separately from principal and interest.

Planning an Ontario Home Purchase?

A mortgage payment is only one part of buying a property. Review your down payment, closing costs, taxes, financing requirements, and property-specific expenses before deciding what fits your budget.
