The Cost of Refinancing a Loan: The Fees That Decide It and the Break-Even That Settles It

Refinancing a loan means taking out a new loan and using the proceeds to pay off an existing one. The fees you pay to make that switch, and how long the monthly saving takes to cover them, decide whether you come out ahead. Everything else — the advertised rate, the new payment, the friendlier term — is downstream of those two numbers.

What refinancing actually changes

A loan refinance is not a modification of your existing contract. It is a new contract. The old loan is paid out and closed, and a new one begins with its own rate, its own term and its own fee schedule. That distinction matters, because paying out the old loan is itself a trigger for charges.

Three variables normally change at once:

• Rate. The interest charged on the outstanding balance.
• Term and amortisation. How long you have to repay, and therefore how much total interest you pay.
• Structure. Whether the new loan is unsecured, or secured against property such as a home or vehicle.

Any one of these can improve while another gets worse. A lower rate on a longer term is the most common example: the payment falls, but the total cost rises.

The fees that decide a refinance

Fee names vary by lender and by province, but the categories are consistent. Work through this table before you sign anything.

Two of these deserve emphasis. First, the payout penalty on the existing loan is frequently the single largest cost, and it is calculated by the old lender rather than the new one — so it is easy to overlook while you are comparing new offers. Second, a set-up fee added to the balance rather than paid upfront is not free: you pay interest on it for the whole term.

The Financial Consumer Agency of Canada's guidance on personal loans is a sensible starting point for understanding the difference between the headline interest rate and the total cost of borrowing, which is the figure that actually matters here.

Costs that never appear on a fee sheet

Term reset

If you have been paying a loan for three years and refinance back onto a full original term, you have restarted the clock. The payment drops because the debt is spread over more months, not because the debt is cheaper.

Compounding

In Canada, fixed-rate mortgages are compounded semi-annually by law, so the posted rate is not the effective annual rate you actually pay. The FCAC's mortgage material explains how to compare rates on a like-for-like basis. Comparing a semi-annually compounded rate against one compounded monthly, without adjusting for the difference, is a common and expensive error.

Turning unsecured debt into secured debt

Refinancing credit card or unsecured instalment debt into a secured loan or a home equity line of credit usually lowers the rate, sometimes substantially. What you give up is the safety net: unsecured debt generally does not put your home at risk, and secured debt does. At federally regulated lenders, home equity lines of credit are generally limited to 65% of appraised property value, with total secured lending usually capped at 80%. The FCAC's mortgages pages set out those limits and the qualifying rules that accompany them.

Qualifying rules that set your rate

Even a well-priced refinance depends on qualifying. Federally regulated mortgage lenders generally work to a total debt service ratio ceiling of about 44%, and apply a qualifying stress-test rate above the contract rate under Guideline B-20. Consolidating several debts into one payment can look like a cash-flow improvement while actually pushing you past a ratio ceiling. That is one reason a professional assessment is worth having before you commit.

Credit inquiries

Every full application leaves a hard inquiry on your file, and several in a short period can affect how a lender prices your application. Requesting your own report does not.

Cost-of-borrowing ceilings

The Criminal Code sets the criminal rate of interest at 35% per year, calculated using a defined method that aggregates interest and certain charges. Where a province operates a licensed payday lending regime, federal payday lending regulations (SOR/2024-114) cap the cost of borrowing at $14 per $100 advanced; some provinces set a lower cap and the lower figure applies. Payday loans are generally up to $1,500 for a term of 62 days or less, and Quebec does not license payday lending, which effectively prohibits the model there. These ceilings are a legal backstop, not a benchmark for a good deal — the FCAC's personal loans guidance explains how the cost of borrowing is calculated in practice.

The break-even calculation

Break-even is the point at which the money you have saved equals the money you spent to refinance. In its simplest form:

Break-even in months = total refinance costs ÷ monthly payment reduction

Run it in four steps:

1. Total the costs. Every fee from the table above, plus the payout penalty on the old loan, plus any fee financed into the new balance, plus any overlap period where you are paying interest on both loans at once.
2. Establish the real monthly saving. New payment minus old payment. If the old loan's payment was scheduled to change, use the payment that would actually have applied.
3. Divide. The result is your break-even in months.
4. Compare it with your realistic holding period. Not the term you signed — the time you genuinely expect to keep this loan before selling, moving or refinancing again.

If the break-even is longer than your realistic holding period, the refinance costs you money. That is the whole test.

There is a second check that catches the most common mistake: compare total interest paid under the old loan and the new one, running each to its own end date. If the payment fell but total interest rose, you bought cash flow, not savings. That can still be a legitimate choice — but you should know you are making it. A third check, for larger refinances, is to discount the future savings back to today; if the discounted saving is smaller than the costs you pay today, the deal is weak on paper even when the break-even month looks acceptable. Decisions at this scale are worth discussing with a licensed professional who can see your full financial picture.

Where refinancing goes wrong

• Refinancing to shrink a payment you could already afford. If the goal is a smaller payment rather than a smaller debt, the underlying problem is unchanged.
• Financing the fees. Rolling costs into the balance hides them and adds interest on top.
• Ignoring the new loan's prepayment terms. If you refinance again later, you may pay the same kind of penalty twice.
• Breaking a fixed-rate mortgage without running the numbers. The interest differential charge can exceed the entire rate saving.
• Applying to many lenders at once. A cluster of hard inquiries can work against you.
• Refinancing debt that is already unmanageable. If payments no longer fit your income, a refinance may postpone the problem rather than solve it.

Credit reporting, and the options beyond refinancing

Canada has two national credit reporting bureaus — Equifax Canada and TransUnion Canada — and a free copy of your credit report is available from each. Read both before you apply; a decision based on one bureau's file can miss an error recorded on the other.

If the debts are already beyond what refinancing can fix, there are formal alternatives. A consumer proposal stays on a credit report for three years after completion, or six years from filing, whichever comes first. A first bankruptcy stays on a credit report for six years after discharge. Only a licensed insolvency trustee can administer a consumer proposal or bankruptcy, and trustees are regulated by the Office of the Superintendent of Bankruptcy Canada. These are legal processes rather than products, and the right route depends entirely on individual circumstances — speak with a licensed trustee or a regulated credit counsellor before acting.

If something goes wrong

Complaints about federally regulated financial institutions are handled by the Financial Consumer Agency of Canada. Provinces license and supervise most other lenders, and each province has a consumer protection office. Keep the disclosure documents you receive at signing; they contain the total cost of borrowing and form the basis of any complaint.

The lowest rates advertised in any market — including the refinance market — are available only to the most qualified applicants, and the rate you are offered depends on your credit history, income, existing debts and the security you can provide. Treat any advertised rate as the starting point for your own break-even calculation, not as a promise.
