What Is APR? Interest Rate vs APR in Canada, Explained Simply
By Jordan Ellis · Published · Reviewed
Quick Answer
APR (annual percentage rate) is the total yearly cost of borrowing, including the interest rate plus mandatory fees like origination charges. A loan at 9% interest with a 4% origination fee has an APR around 11.7% — which is why you should always compare loan offers by APR, not the headline rate.
The definition that matters
APR is the price of a loan expressed as one yearly number: interest plus the fees you can’t avoid. Canada’s cost-of-borrowing disclosure rules under the Bank Act, overseen by the FCAC, exist precisely because lenders used to advertise low rates while burying costs in fees. APR is the great equalizer — it forces every lender to quote on the same basis.
Interest rate vs. APR, in dollars
Two offers for a $10,000, 3-year personal loan:
| Offer A | Offer B | |
|---|---|---|
| Interest rate | 8.5% | 10.0% |
| Origination fee | 5% ($500) | 0% |
| Monthly payment | $316 | $323 |
| APR | ~12% | 10% |
| Total cost | $11,376 | $11,616 |
Offer A wins on total dollars here, but notice how the fee dragged its “cheap” 8.5% rate up to a 12% APR. If you borrowed less or for a shorter term, the fee would dominate even more — on short loans, fees matter more than rate. Our personal loan calculator shows both the cash you actually receive and total cost for exactly this comparison.
What’s inside (and outside) the APR
Usually included: interest and required fees such as administration or lender fees.
Usually not included: late or NSF fees, prepayment charges, optional add-ons like credit insurance, and, on credit cards, annual fees and balance transfer fees. Your cost-of-borrowing disclosure lists what applies to your loan.
That gap matters: a card’s interest rate tells you nothing about its $120 annual fee or 3% transfer fee.
APR on credit cards vs instalment loans
On instalment loans (personal, auto, mortgage), APR is a comparison tool: you pay it as part of a fixed schedule. On credit cards, it’s a live threat: carry a balance and interest is calculated daily (the annual rate ÷ 365 applied to each day’s balance) and added to your balance each statement. A 24% rate costs about 2% of the balance every month. See the damage in the credit card payoff calculator.
Fixed vs. variable APR
Variable rates (lines of credit, HELOCs and variable-rate mortgages) float with prime, so your cost rises when the Bank of Canada raises rates. Most Canadian credit cards and most personal and auto loans have fixed rates, although a card issuer can change its rates with notice. In a rising-rate environment, that distinction is worth real money.
The bottom line
APR is the single most honest number in any loan offer — but only within the same loan type and term. Compare APR to APR, check what fees it excludes, and remember the cheapest loan is still the one you pay off fastest.
