Mortgage refinancing: when it makes sense and what it costs
By Mark Herman, Calgary mortgage broker, MBA in Finance. Last updated .
Refinancing replaces your current mortgage with a new one, usually to access home equity, consolidate debt, or change your terms. In Canada you can generally borrow up to 80% of your home's appraised value through a refinance. It makes sense when the savings or benefits outweigh the costs, including any prepayment penalty, legal fees, and appraisal. Running a break-even calculation before you commit is essential.
When does refinancing make sense?
Common reasons to refinance include paying off high-interest debt, funding a renovation, helping a family member, investing, or restructuring a mortgage that no longer fits. Separating or divorcing couples also refinance to buy out a former partner.
Refinancing is not automatically a good idea. Rolling short-term debt into a mortgage can lower your monthly payments while increasing the total interest you pay over a longer period. It works best when you also address what created the debt, or when the money is being used for something that adds value.
How to access your home equity
Your available equity is roughly the difference between 80% of your home's appraised value and your existing mortgage balance. For example, if your home appraises at $600,000, 80% is $480,000. With a $350,000 balance, you might access up to about $130,000 before costs, subject to qualification.
There are several ways to access equity. A traditional refinance replaces your mortgage with a larger one. A home equity line of credit (HELOC) gives revolving access to funds, and standalone HELOCs are generally limited to 65% of the home's value. Some homeowners use a second mortgage or a blended option with their current lender to avoid breaking an existing term.
You still have to qualify. Lenders review income, credit, and debt ratios, and most borrowers are stress tested. An appraisal confirms the value.
Debt consolidation through refinancing
Credit card balances and some personal loans typically carry much higher interest rates than mortgages. Consolidating them into your mortgage can reduce monthly payments and simplify your finances. The trade-off is that you are securing unsecured debt against your home and potentially paying it off over many more years.
If you consolidate, consider making extra payments so the debt is repaid sooner, and avoid running the cards back up. We map out what your payments and total interest look like before and after so you can make a clear decision.
HELOC vs refinance: which is better?
A refinance gives you a lump sum and folds it into a new mortgage with a fixed or variable rate and a set repayment schedule. It often makes sense for a known, one-time need such as paying out debts or a planned renovation, but it may trigger a penalty on your current mortgage.
A home equity line of credit is revolving credit. A standalone HELOC is generally limited to 65% of the home's value, and combined with a mortgage the total is generally capped at 80%. Rates are usually variable and minimum payments can be interest-only, so balances can linger. HELOCs suit ongoing or uncertain expenses when you have the discipline to pay them down.
Worked break-even example
Here is a hypothetical all-in break-even calculation. Every figure is illustrative. Your actual penalty and fees depend on your lender and contract, so get written quotes first.
| Item | Amount |
|---|---|
| Prepayment penalty (lender quote) | $4,800 |
| Legal and registration | $1,200 |
| Appraisal | $400 |
| Discharge and admin fees | $300 |
| Less lender cash-back or cost coverage | -$700 |
| All-in cost | $6,000 |
| Estimated monthly interest savings | $250 |
| Break-even | $6,000 / $250 = 24 months |
If you expect to keep the new mortgage well beyond 24 months and the savings are real interest savings rather than just a longer amortization, the refinance may make sense. If not, waiting for maturity or using a HELOC may be cheaper. For more on lines of credit, see the HELOC guide.
Penalties and costs to expect
If you refinance before your term ends, your lender will usually charge a prepayment penalty. For variable mortgages, it is often three months' interest. For fixed mortgages, it is often the greater of three months' interest or an interest rate differential (IRD), and IRD penalties can be large. Ask your lender for a written penalty quote and how it was calculated.
Other costs can include legal fees, an appraisal, discharge or registration fees, and possibly fees for alternative or private lenders. Some lenders offer cash-back or cover legal costs on certain products. Every cost should be on the table before you compare options.
The break-even calculation
To find your break-even point, add up all refinance costs, including the penalty. Then estimate your monthly savings from the new rate or from replacing higher-interest debt. Divide total costs by monthly savings to estimate how many months it takes to recover the costs.
Use an all-in number: the penalty plus legal, appraisal, discharge, registration, and any lender or insurance costs, less any cash-back. For example, if all-in costs total $6,000 and you save $250 a month in interest, it takes about 24 months to break even. If you might sell or move before then, the refinance may not pay off. Look at interest savings, not just lower payments, because a longer amortization can lower payments while increasing total interest.
Also compare alternatives. Waiting until your renewal date, using a blend-and-extend, or a HELOC may cost less than breaking your mortgage today.

Frequently asked questions
How much equity can I take out when I refinance?
Most lenders allow a refinance up to 80% of your home's appraised value, minus your existing mortgage, subject to qualifying on income, credit, and the stress test.
What is the penalty for refinancing early?
Variable mortgages often charge three months' interest. Fixed mortgages often charge the greater of three months' interest or an interest rate differential. Ask your lender for a written quote.
Is it smart to consolidate debt into a mortgage?
It can lower payments and interest rates, but it may increase total interest over a longer period and secures the debt against your home. Compare both scenarios first.
How do I calculate my refinance break-even point?
Divide total refinance costs, including penalties and fees, by your expected monthly savings. The result is roughly the number of months needed to recover the costs.
Is a HELOC better than refinancing?
A HELOC is flexible and may avoid breaking your mortgage, but rates are usually variable and payments can be interest-only. A refinance offers structured repayment. The best choice depends on how you will use the funds.
How much equity do I need to refinance?
Most refinances are capped at 80% of the appraised value. For a home worth $700,000, the maximum total mortgage would generally be $560,000, subject to qualifying.
Can I refinance with bad credit?
Possibly, through alternative or private lenders, usually at higher rates and with fees. Equity, income, and your plan to repay matter. No approval is guaranteed.
How long does a refinance take?
It depends on the lender, the appraisal, and how quickly documents and legal work are completed. Starting early helps, especially if you need funds by a deadline.
Can I refinance a rental property?
Yes, but rental refinances are often limited to a lower loan-to-value than a principal residence, and lenders treat rental income differently. Ask about your specific property.
Are refinance fees and penalties the same everywhere?
No. Penalties, appraisal requirements, legal fees, and any cash-back or cost coverage are lender specific. Compare all-in costs between options.
