Mortgage Payment Calculator Canada
See the loan payment, financed mortgage balance, total interest, and the real 20 / 25 / 30-year amortization tradeoff.
Kept deliberately narrow: property tax, utilities, maintenance, condo fees and the full cost of owning the home belong in the Total Cost of Homeownership Calculator Canada.
No income-ratio verdict and no household ownership-cost estimate are mixed into this result.
Canadian mortgage formula, insured-loan rules, and scope boundary
Included

- Estimated mortgage loan insurance when applicable
- Contract rate, standard payment frequency and amortization
- Selected payment, monthly equivalent, total interest and balance path
- 20 / 25 / 30-year amortization comparison
Deliberately excluded

- Income affordability, GDS/TDS, stress-test approval or lender underwriting
- Closing costs, land transfer tax, refinance and renewal events
- Accelerated bi-weekly strategy and extra-payment optimization
Formula
The nominal annual mortgage rate is converted from Canadian semi-annual compounding to the equivalent rate for the chosen standard payment frequency. The amortizing-payment formula is then applied to the financed principal.
Official rule references

Build the loan payment
Only inputs that change the financed mortgage or amortization math are included.
Purchase and mortgage balance
Loan terms
Mortgage loan insurance can increase the financed balance when down payment is below 20%.
A 30-year amortization can reduce the payment substantially while adding years of interest cost.
Standard bi-weekly and weekly payment frequencies are included; accelerated strategy is kept in the separate bi-weekly comparison tool.
How your purchase becomes a mortgage payment
One loan-only flow: purchase price minus down payment, plus financed mortgage insurance where applicable, becomes the balance that creates the scheduled payment.
Same financed balance and amortization, using the higher rate only to expose sensitivity.
Amortization Decision Map
20, 25 and 30 years use the same purchase setup and rate. The only thing changing is how long the mortgage is stretched — exactly the tradeoff this page should explain.

Mortgage Visual Map
Not decorative charts: one view shows where the repayment money goes, and the other shows how quickly the financed balance actually burns down.
Principal vs interest
The full modeled repayment split under the selected amortization and rate.
Balance burn-down
The remaining financed mortgage after each modeled year. Milestones make the pace of principal reduction easy to read.
How to use the mortgage payment result
Start with the purchase price and down payment because those determine the base mortgage. Then enter the contract rate and choose the amortization. The selected payment frequency changes how often the scheduled loan payment is made, but this page keeps the decision centered on the mortgage itself.
After Calculate, read the selected payment first, then the financed balance and total interest. The 20 / 25 / 30-year comparison shows the tradeoff that is easy to miss: a lower payment can be more expensive when it comes from keeping the balance outstanding for longer.
What your mortgage payment actually means
The payment shown here is the scheduled loan payment — not the full cost of living in the home. That distinction is intentional. Property tax, home insurance, utilities, maintenance and condo fees vary independently from the mortgage and are better tested in the Total Cost of Homeownership Calculator Canada.
The total-interest estimate is also a controlled comparison, not a forecast of every future renewal. It assumes the entered rate continues through the modeled amortization. Use it to understand the cost direction of 20 versus 25 versus 30 years, then use the Mortgage Renewal Calculator Canada when the next-term rate becomes the decision.
How to choose between 20, 25 and 30 years
Choose 20 years when payment room is strong
A shorter amortization normally means the highest scheduled payment but the lowest constant-rate interest of the three comparisons.
Use 25 years as the middle comparison
Twenty-five years often sits between payment flexibility and lifetime borrowing cost. The calculator shows the exact tradeoff for the entered balance and rate.
Choose 30 years for payment relief, not “savings”
The monthly payment may fall, but the balance remains outstanding longer. Read the extra interest before treating the lower payment as a cheaper mortgage.
Do not use this page as an approval test
Income, debts and qualifying-rate rules belong in the Mortgage Affordability Calculator and Mortgage Stress Test Calculator.
Real mortgage-payment scenarios
Common mistakes
Calling the mortgage payment the “cost of the home”
It is only the loan repayment. Keep taxes, maintenance, utilities and insurance in the separate homeownership-cost decision.
Assuming the lowest payment is the cheapest loan
A 30-year amortization can lower the payment and still create much more interest than 20 or 25 years.
Ignoring financed mortgage insurance
When applicable, the estimated premium increases the mortgage principal and therefore affects both payment and interest.
Using this page for accelerated-payment strategy
For accelerated bi-weekly versus monthly, use the dedicated frequency comparison so the payoff and cash-flow tradeoff stays explicit.
How the Canadian mortgage calculation works
Home price minus down payment gives the base mortgage. When an insured mortgage is eligible and the down payment is below 20%, the model estimates the applicable mortgage-loan-insurance premium and adds it to the financed principal. The payment calculation then uses Canadian mortgage-rate convention: the nominal annual rate compounded semi-annually is converted to the equivalent periodic rate for the selected standard payment frequency.
payment = principal × periodRate ÷ (1 − (1 + periodRate)^−numberOfPayments)
Each amortization comparison uses the same purchase setup and rate. That keeps the decision forensic: the change in payment and total interest comes from the length of the amortization, not from taxes, utilities, income assumptions or a different home.
Mortgage payment FAQ
No. This page deliberately isolates the mortgage loan. Use Total Cost of Homeownership for property tax, home insurance, utilities, maintenance and condo fees.
Because the principal remains outstanding for longer. More payment periods generally create more total interest when the balance and rate are otherwise held constant.
No. Lender approval, income ratios, debts and the qualifying-rate stress test are separate. Use the affordability and stress-test calculators for those questions.
Standard monthly, semi-monthly, bi-weekly and weekly schedules are modeled over the selected amortization. Accelerated bi-weekly is intentionally excluded here because it changes annual cash flow and is handled by the dedicated frequency-comparison calculator.
The model holds the entered rate constant through the amortization. Real Canadian mortgages renew, and future rates, refinancing, prepayments or a sale can change the actual interest paid.
