How Does Car Financing Work?
Car financing can feel confusing, but it boils down to a few key concepts. Here's a plain-English explanation of how car loans work in Canada.
Car financing is simply borrowing money to buy a vehicle and paying it back over time with interest. Here's how it works in Canada, in plain English.
The basics: principal, interest, and term
Every car loan has three core components:
- Principal: The amount you borrow (vehicle price minus down payment and trade-in)
- Interest rate: The cost of borrowing, expressed as an annual percentage (APR)
- Term: How long you have to repay, typically 48–84 months in Canada
Your monthly payment is calculated based on these three factors. A higher principal or interest rate means a higher payment. A longer term means a lower payment but more total interest paid.
Example: a $25,000 loan
| Term | Rate | Monthly Payment | Total Interest |
|---|---|---|---|
| 48 months | 5.99% | $586 | $3,128 |
| 60 months | 5.99% | $483 | $3,980 |
| 72 months | 5.99% | $415 | $4,880 |
| 84 months | 5.99% | $366 | $5,744 |
As you can see, extending the term lowers your monthly payment but increases the total cost of borrowing.
How interest is calculated
In Canada, most car loans use simple interest, which means interest is calculated on the remaining principal only. Unlike some credit cards, you don't pay interest on interest. Making extra payments or paying off the loan early reduces total interest — though some lenders charge a prepayment penalty.
Fixed vs. variable rates
- Fixed rate: Stays the same for the entire term. Most Canadian car loans are fixed. Your payment never changes.
- Variable rate: Can go up or down with the lender's prime rate. Less common for car loans.
Where to get car financing
- Dealership financing: Convenient, but rates may be higher. Good for people with credit challenges — dealers have access to subprime lenders.
- Banks: Often have the best rates for customers with strong credit. Get pre-approved before shopping.
- Credit unions: Member-owned, often offer competitive rates and more flexible terms.
- Online lenders: Quick approval, competitive rates, but less personal service.
What affects your interest rate?
- Credit score: The biggest factor. 750+ gets the best rates, below 600 means subprime rates
- Down payment: More down = lower rate (less risk for the lender)
- Loan term: Shorter terms often get lower rates
- Vehicle age: Newer vehicles typically qualify for lower rates
- Debt-to-income ratio: Lower existing debt = better rate
The approval process
- You submit an application with your personal, income, and credit information
- The lender pulls your credit (a hard inquiry) and assesses risk
- If approved, they set your rate and term based on your credit profile
- You sign the loan agreement and drive away
- You make monthly payments until the loan is paid off
Pre-qualification vs. pre-approval
Pre-qualification (what Affordrive does) gives you an estimate based on self-reported information without a hard credit check. Pre-approval involves a hard credit pull and gives you a firm rate and amount. Pre-qualify first to understand your options, then get pre-approved when you're ready to buy.
Get pre-qualified in 3 minutes — no credit check required.
