How to Use This Calculator
This mortgage calculator helps you estimate your monthly payments and total interest costs for a home purchase in Ontario. Follow these steps:
- Enter the loan amount (the total amount you want to borrow).
- Enter the interest rate (the annual percentage rate for your mortgage).
- Select the amortization period (how long you'll pay back the loan).
- Click Calculate to see your estimated monthly payment and total interest paid.
The calculator uses the standard mortgage payment formula to provide an estimate. For exact figures, consult with a mortgage professional.
Formula Used
The calculator uses the standard mortgage payment formula:
Mortgage Payment Formula
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (amortization period in years × 12)
This formula calculates the fixed monthly payment required to fully amortize a loan over the specified term.
Worked Example
Let's calculate a mortgage payment for a $300,000 loan at 5% interest over 25 years:
Example Calculation
Loan Amount: $300,000
Interest Rate: 5% (0.05)
Amortization Period: 25 years
Monthly Interest Rate: 5% ÷ 12 = 0.4167% (0.004167)
Number of Payments: 25 × 12 = 300
Monthly Payment: $300,000 [ 0.004167(1 + 0.004167)^300 ] / [ (1 + 0.004167)^300 - 1 ] ≈ $1,724.56
Total Interest Paid: ($1,724.56 × 300) - $300,000 ≈ $157,368
This example shows that a $300,000 loan at 5% over 25 years would have a monthly payment of approximately $1,724.56, with $157,368 paid in interest.
Mortgage Calculator Guide
Understanding Mortgage Terms
Before using the calculator, familiarize yourself with key mortgage terms:
- Principal: The original amount borrowed.
- Interest Rate: The percentage charged on the loan.
- Amortization Period: The length of time to repay the loan.
- Monthly Payment: The fixed amount paid each month.
- Total Interest: The total amount paid in interest over the life of the loan.
How to Choose an Amortization Period
The amortization period is the length of time you'll pay back your mortgage. Common options include:
- 5 years (short-term, higher payments)
- 10 years (moderate payments)
- 15 years (lower payments)
- 20 years (common default)
- 25 years (long-term, lower payments)
Shorter terms mean higher monthly payments but less total interest paid. Longer terms mean lower monthly payments but more total interest paid.
Mortgage Payment Breakdown
Your monthly payment consists of two parts:
- Principal Payment: The portion that reduces the loan balance.
- Interest Payment: The portion that covers the cost of borrowing.
Over time, the principal payment increases while the interest payment decreases as the loan balance decreases.
Amortization Schedule
An amortization schedule shows how your loan balance changes over time. It includes:
- Payment number
- Payment amount
- Principal portion
- Interest portion
- Remaining balance
This schedule helps you understand how quickly you'll pay off your mortgage and how much interest you'll pay over time.
Mortgage Prepayment
Mortgage prepayment is paying off your loan early. Benefits include:
- Reduced total interest paid
- Lower monthly payments
- Potential tax benefits
Important Note
Check with your lender about prepayment penalties before making extra payments.
Mortgage Insurance
If you make a down payment of less than 20% in Ontario, you may need mortgage default insurance. This protects the lender if you default on your mortgage.
Frequently Asked Questions

This calculator provides an estimate based on standard mortgage formulas. For exact figures, consult with a mortgage professional or use your lender's calculator.

How does the amortization period affect my payments?
A longer amortization period means lower monthly payments but more total interest paid. A shorter period means higher monthly payments but less total interest paid.
What is the difference between principal and interest payments?
Principal payments reduce the loan balance, while interest payments cover the cost of borrowing. Over time, principal payments increase while interest payments decrease.
Do I need mortgage insurance in Ontario?
