Mortgage Payoff Calculator Ontario

Paying off your mortgage early can save you thousands in interest payments. Our Ontario mortgage payoff calculator helps you determine exactly how much you'll save by making extra payments or paying off your mortgage ahead of schedule.

How to Use This Calculator

To use the mortgage payoff calculator, simply enter your current mortgage balance, interest rate, and the amount you plan to pay extra each month. The calculator will show you:

The new payoff date with your extra payments
The total interest saved by paying off early
A comparison of your original vs. accelerated payoff

You can also see how your extra payments affect your mortgage balance over time with the interactive chart.

Formula Used

The calculator uses the standard mortgage amortization formula to calculate your payoff date and interest savings. The key calculations are:

Monthly Payment:

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

Where:

P = Monthly payment
L = Loan amount
r = Monthly interest rate (annual rate ÷ 12)
n = Number of payments (loan term × 12)

Payoff Date:

The calculator tracks the mortgage balance month by month, subtracting both the regular payment and any extra payments you make.

The calculator then compares the original payoff date with the new payoff date when extra payments are made, showing the difference in interest paid.

Worked Example

Let's look at an example to see how the calculator works. Suppose you have a $300,000 mortgage at 5% interest with a 25-year term.

Scenario	Payoff Date	Total Interest Paid	Interest Saved
Regular payments only	December 2045	$150,000	$0
Extra $200/month	June 2038	$120,000	$30,000

In this example, making just $200 extra each month saves you $30,000 in interest and shortens your payoff by 7 years.

Payoff Strategies

There are several ways to pay off your mortgage early in Ontario:

Extra Monthly Payments

Making extra payments each month is the most common strategy. Even small extra payments can significantly reduce your interest costs and payoff date.

Bi-Weekly Payments

Paying every two weeks instead of monthly gives you an extra payment every year. This can save you thousands over the life of your mortgage.

Lump Sum Payments

Making one-time lump sum payments can be particularly effective if you receive a bonus, tax refund, or inheritance.

Refinance to Lower Rates

If interest rates drop significantly, refinancing can save you money in the long run, even if it takes longer to pay off the mortgage.

Note: In Ontario, mortgage interest is tax-deductible, so paying off early can provide both financial and tax benefits.
