How this calculator works

Refinancing swaps your existing mortgage for a new one β€” with your current lender or a new one β€” usually on your existing outstanding balance (or higher, if accessing home equity). The calculator works out your monthly payment on both the current and new deal, then compares them:

Monthly saving = current monthly payment − new monthly payment

If the new deal has fees β€” appraisal, legal, discharge, and/or a prepayment penalty for breaking your current term early β€” those fees eat into your saving before you're better off overall. The calculator finds yourbreak-even month (fees divided by the monthly saving, rounded up) and a lifetime saving figure over the shorter of your two remaining amortization periods, after fees. If the new deal doesn't actually lower your payment, there's no break-even point to find, and the calculator says so clearly.

Worked example

Say you have $350,000 outstanding, currently on a 6% rate with 22 years remaining. You're offered a new deal at 4.8% over a fresh 25-yearamortization, with $1,500 in fees. The new deal noticeably lowers your monthly payment, and that saving typically recoups a fee of this size within a matter of months β€” with a substantial lifetime saving over the comparison term once fees are subtracted. Bear in mind part of any saving reflects stretching the loan back to a fresh 25-year amortization rather than the 22 years remaining β€” worth weighing alongside the monthly saving.

What affects your result

  • The rate gap β€” the difference between your current and new rate is the single biggest driver of your monthly saving.
  • New deal fees, including any prepayment penalty β€” a lower rate with a large IRD penalty for breaking your term early can take much longer to break even than waiting until your term ends.
  • Amortization changes β€” resetting to a longer amortization lowers the monthly payment further but increases total interest paid over the life of the loan.
  • Fixed vs variable rate type β€” remember that fixed-rate mortgages compound semi-annually by law, while variable-rate mortgages compound monthly, at the identical quoted rate.

A note on accuracy

This calculator compares principal-and-interest payments only, using unrounded figures internally with rounding applied solely for display. It does not automatically calculate an Interest Rate Differential (IRD) penalty for breaking your current term β€” get an exact payout quote from your current lender and add it to the new deal fees field if applicable.

Frequently asked questions

How much can I save by refinancing my Canadian mortgage?

It depends on the gap between your current rate and the new rate, and the fees involved. For example, refinancing a $350,000 balance from a 6% rate (with 22 years remaining) to a 4.8% rate over 25 years cuts the monthly payment noticeably, and a $1,500 refinance fee is typically recouped within a handful of months. Use the calculator above with your own numbers for an exact figure.

What fees are involved in refinancing in Canada?

Typical costs include an appraisal fee, legal fees, a mortgage discharge fee from your current lender, and β€” if you're breaking your current term before it ends β€” a prepayment penalty, which for fixed-rate mortgages is usually the greater of three months' interest or the Interest Rate Differential (IRD), a calculation based on the difference between your contract rate and the lender's current rate for a similar remaining term. IRD penalties can be substantial, so always get an exact payout quote from your current lender before refinancing mid-term.

What does "break-even month" mean when refinancing?

It's how many months it takes for your monthly saving on the new mortgage to add up to more than the fees (including any prepayment penalty) you paid to get it. If the break-even point is, say, 8 months, you come out ahead from month 9 onward. If the new deal doesn't actually lower your monthly payment β€” or saves so little that the fees are never fully recouped within the new term β€” the calculator tells you plainly rather than showing a misleading number.

Can I refinance to access home equity in Canada?

Yes β€” this is one of the most common reasons Canadians refinance, often called a "cash-out refinance" or increasing your mortgage to access equity. Federally regulated lenders generally cap this at 80% loan-to-value of your home's current appraised value. This calculator focuses on comparing payments between your current and new rate/term rather than modelling an increased loan amount, so add any extra funds you're taking out to the new loan balance manually if you're refinancing to access equity.

Is it worth refinancing before my term ends?

It can be, if the rate improvement is large enough to outweigh the prepayment penalty (often an IRD charge on fixed mortgages) for breaking your current term early. Since IRD penalties scale with both your remaining term and the rate difference, refinancing tends to make more sense either close to your renewal date (when the penalty shrinks) or when rates have moved enough to produce a large ongoing saving. Get an exact penalty quote from your current lender before deciding.

Should I refinance with my current lender or switch lenders?

Both are common. Staying with your current lender (sometimes at renewal, without a full refinance) can be simpler and sometimes fee-free, but you may not get the most competitive rate. Switching lenders can secure a better rate but typically involves the fees this calculator lets you enter β€” appraisal, legal, and discharge costs. It's generally worth comparing offers from multiple lenders or working with a mortgage broker before committing.
