Mortgage Refinance Calculator

Refinancing replaces your mortgage with a new one, usually to get a lower rate or to borrow against your equity. Lenders typically lend up to 80% of the home’s value. Enter the penalty your lender quoted; we don’t guess it.

Switching rates alone (no extra borrowing) saves about $227.45 a month, so the penalty and fees pay for themselves in about 33 months.

How refinancing works

Refinancing replaces your mortgage before the term ends. In Canada you can usually borrow up to 80% of your home’s value, so the equity available is 80% of the value minus what you owe. Breaking a closed term early costs a penalty: typically three months’ interest on a variable rate, and on a fixed rate the greater of three months’ interest or the interest rate differential. Only your lender can give you the exact figure.

Is it worth breaking my mortgage for a lower rate?

Say you owe $420,000 at 5.6% with 20 years left: $2,897.62 a month. Switching to 4.39% with a $6,000 penalty and $1,500 in fees added to the new mortgage makes the payment $2,670.17, saving $227.45 a month. The costs are paid back in about 33 months; if your term has longer than that left, the switch likely pays off. On a $900,000 home, up to $300,000 of equity would also be available to borrow.

What this estimate doesn’t include

  • Your lender’s exact penalty, which depends on your contract and current posted rates.
  • Approval: a refinance is a new mortgage, so the lender checks income, credit and an appraisal.
  • Other options, such as a blend-and-extend with your current lender or a home equity line of credit.
  • Rate changes when the new term ends.

Actual payments, qualification, rates, insurance, taxes and fees depend on your lender, contract and circumstances. Projections hold your entered rate constant after the term; future rates may differ.
