The interest rate prices the money; the cost of borrowing prices the loan
An interest rate is the price a lender charges on the principal you still owe. It is usually quoted as a yearly percentage, and it is applied to a balance that shrinks as you make payments. Two loans can carry the same headline rate and still cost different amounts, because the rate interacts with the term, the payment schedule and how often interest is compounded. Canadian fixed-rate mortgages, for example, are compounded semi-annually by law, so interest on a mortgage does not build up the same way it does on a loan that compounds monthly.
The total cost of borrowing is the wider figure. It combines the interest with the fees and charges a lender requires you to pay in order to get the money: administration or origination fees, arrangement fees, insurance the lender arranges, discharge fees and any prepayment charge that applies if you pay the loan off early. In Canada you will usually see this annualized figure described as the cost of borrowing. APR is the label used in some other markets for much the same idea. The name matters less than what sits inside it, and the annualized total is the number to compare.
A loan interest calculator will show you what the rate alone does to a balance over time. It will not know about fees unless you put them in. If you run a rate through a loan interest calculator and stop there, you have priced the money rather than the loan, and you have priced it too low.
Why two loans with the same rate can cost different amounts
The rate is one input into the total. These are the others:
- Term. A longer term spreads the payments out but usually increases the total interest paid, even at a lower rate.
- Compounding. Interest that compounds more often grows faster on an unpaid balance.
- Mandatory fees. A fee charged up front is money you pay whether or not you keep the loan, and it raises the effective annual cost above the quoted rate.
- Payment frequency. Paying weekly or biweekly rather than monthly reduces the balance sooner and reduces total interest.
- Security. Secured borrowing usually prices lower than unsecured borrowing, because the lender has something to recover if you default.
- Your credit profile. Lenders price risk, so the same product is offered at different rates to different applicants.
- Exit costs. Prepayment penalties and discharge fees are part of what the loan costs if you finish it early or move it.
This is why a single quoted rate cannot answer the question, what will this cost me? An interest on loan calculator that ignores fees and penalties will make an expensive loan look cheaper than a modest one. Put the total cost of borrowing into your comparison, not the rate.
Comparing the numbers side by side
| What you are looking at | What it includes | What it leaves out | What it is useful for |
|---|---|---|---|
| Interest rate | Interest on the outstanding balance, at the stated compounding frequency | Fees, insurance, penalties and any charge that is not interest | Understanding how the balance behaves month to month |
| Total cost of borrowing (the APR idea) | Interest plus the mandatory fees and charges attached to the loan, expressed on an annual basis | Optional products you choose to buy, and costs that depend on how you use the loan | Comparing two or more offers on the same footing |
Read that table left to right. The further right you go, the closer you get to the number that actually leaves your bank account.
How the main borrowing options compare
| Type of borrowing | Typical shape | What drives the total cost | Regulatory context |
|---|---|---|---|
| Personal or instalment loan | Term loan repaid on a set schedule | Rate, term, fees and your credit profile | The regulator and the rules depend on who licenses the lender |
| Payday loan | Generally up to $1,500 for a term of 62 days or less | A flat fee charged per $100 advanced | Where a province operates a licensed payday lending regime, the 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 cap applies. Quebec does not license payday lending, which effectively prohibits the model there. |
| Home equity line of credit | Revolving credit secured by your home | The rate and how long you carry the balance | At federally regulated lenders, generally limited to 65% of appraised property value, with total secured lending usually capped at 80% |
| Mortgage | Secured loan repaid over an amortization period | Rate, term, amortization, fees and prepayment penalties | Federally regulated mortgage lenders generally work to a total debt service ratio ceiling of about 44%, and qualify an uninsured mortgage at the greater of the contract rate plus 2 percentage points and 5.25% (OSFI Guideline B-20). Fixed rates are compounded semi-annually by law. |
Notice how different the cost structures are. A payday loan is priced by a flat fee on the amount advanced rather than by a rate applied over years. A mortgage is priced by a rate and shaped by a stress test. Comparing them by headline rate alone tells you very little.
What decides the price you are actually offered
Lenders price risk. Your credit history, income stability, existing debt load and whether the loan is secured all feed into the rate and the fees you are quoted. In Canada, credit history is built from information held by two national credit reporting bureaus: Equifax Canada and TransUnion Canada. Checking your own file with both is a reasonable first step before you apply anywhere, so you know what a lender is looking at.
Past insolvency shows up there too. A consumer proposal stays on a credit report for 3 years after completion, or 6 years from filing, whichever comes first. A first bankruptcy stays on a credit report for 6 years after discharge. Only a licensed insolvency trustee can administer a consumer proposal or a bankruptcy, so if you are dealing with either, that is the professional to speak with.
The lender's own rules also shape what you can borrow. Federally regulated mortgage lenders generally work to a total debt service ratio ceiling of about 44%, and they qualify an uninsured mortgage at the greater of the contract rate plus 2 percentage points and 5.25% under OSFI Guideline B-20. At federally regulated lenders, a home equity line of credit is generally limited to 65% of appraised property value, with total secured lending usually capped at 80%. Those rules can limit how much you qualify for, whatever rate you are offered.
Benchmarks are not offers. The Bank of Canada publishes the policy interest rate, the prime rate, conventional mortgage rates and Government of Canada benchmark bond yields. These are reference points the market watches. No lender is obliged to lend to you at any of them, and the rate you are quoted will reflect your file, the product and the lender's own pricing.
The legal ceiling is a limit, not a target
The Criminal Code sets a criminal rate of interest of 35% per year. That is a ceiling that makes certain lending arrangements a criminal offence. It is not a benchmark, and a loan priced just under it is not a bargain. You can read the wording at section 347 of the Criminal Code (Government of Canada).
Payday lending sits under its own set of rules. Where a province operates a licensed payday lending regime, the federal Payday Lending Regulations (SOR/2024-114) cap the cost of borrowing at $14 per $100 advanced. Where a province sets a lower cap, the lower cap applies. Quebec does not license payday lending, which effectively prohibits the model in that province. Because lending in Canada is licensed provincially, the regulator and the rules differ depending on where you are and who you borrow from.
If you have a complaint about a federally regulated financial institution, the Financial Consumer Agency of Canada handles it. Provinces license and supervise most other lenders, so complaints about those lenders go to the provincial regulator.
How to compare offers, step by step
- Ask for the total cost of borrowing in writing. Not the rate, not the monthly payment, the annualized total including fees.
- Add the fees yourself when you model the loan. A loan calculator is only as honest as the numbers you put into it. If a fee is charged up front, add it to the amount you are borrowing.
- Check the term against your plan. If you expect to pay the loan off early, ask what the prepayment or discharge charge is.
- Confirm who regulates the lender. Federally regulated institutions answer to the Financial Consumer Agency of Canada; provinces license and supervise most other lenders.
- Read the disclosure you are given before you sign. The Financial Consumer Agency of Canada's page on personal loans sets out what you should be told and what to ask about.
- Ask what is optional. Insurance and other add-ons may be presented alongside the loan. Know which charges you must take and which you can decline.
- Do the same calculation for every offer. Same term, same assumptions, same treatment of fees. Then compare.
The lowest rates are only available to the most qualified applicants. That is a statement about how lenders price risk rather than a judgment about you. It means the rate you are offered reflects your file, and it means an advertised rate is a starting position rather than a promise.
Where loanmoose.ca fits
loanmoose.ca is not a lender. It does not make loans, set rates or make credit decisions. It is a matching and comparison service that helps you see what is available and put offers side by side. Any rate, fee and term you are offered comes from the lender, not from loanmoose.ca, and the decision to lend is the lender's alone.
Before you commit to a significant borrowing decision, remember that the right answer depends on your circumstances, your income, your existing debts and your plans. For anything with long-term consequences, speak with a regulated professional who can look at your full picture.
