Formula Used

The calculator uses the standard mortgage payment formula:

Mortgage Payment Formula

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

  • P = Principal loan amount (Purchase Price - Down Payment)
  • r = Monthly interest rate (Annual Rate / 12 / 100)
  • n = Number of payments (Amortization Period × 12)

We also calculate your maximum mortgage amount based on your income and down payment percentage.

Worked Example

Let's say you have an annual income of $80,000, want to put down 10%, and are looking at a 25-year mortgage with a 5% interest rate.

  1. Maximum mortgage amount: $80,000 × 3.5 = $280,000
  2. Down payment: $280,000 × 10% = $28,000
  3. Principal loan amount: $280,000 - $28,000 = $252,000
  4. Monthly payment: $252,000 × (0.004167(1 + 0.004167)^300) / ((1 + 0.004167)^300 - 1) ≈ $1,350

Your estimated monthly payment would be approximately $1,350.

Complete Home Buying Guide for Ontario

Understanding Your Budget

The first step in buying a home is understanding your budget. Ontario's real estate market varies by region, with Toronto and the Greater Golden Horseshoe areas typically having higher prices than rural areas.

Down Payment Requirements

In Ontario, you generally need at least 5% for a conventional mortgage. First-time home buyers may qualify for programs that offer lower down payments, sometimes as low as 3.5%.

Mortgage Insurance

If you put down less than 20%, you'll likely need mortgage default insurance. This adds to your monthly payments but protects the lender if you default.

Interest Rates and Amortization

Current interest rates in Ontario average around 5%. A 25-year amortization is common, but you can choose longer terms which may lower your monthly payments but increase the total interest paid.

Additional Costs

Remember to budget for:

  • Property taxes
  • Home insurance
  • Utilities
  • Moving expenses
  • Renovations or repairs

Getting Pre-Approved

Before house hunting, get pre-approved for a mortgage. This gives you a clear idea of how much you can borrow and makes you a more serious buyer to sellers.

First-Time Home Buyer Programs

Ontario offers several programs to help first-time buyers, including:

  • First-Time Home Buyer Program (FTHBP)
  • Home Buyer's Plan (HBP)
  • Shared Equity Mortgage Program (SEMP)

Closing Costs

Closing costs typically range from 2% to 5% of the home price and include fees for the mortgage, title search, legal fees, and more.
