A car loan can help build credit, because it adds an instalment account that reports a payment every month. It can also do real damage if a payment is missed. The credit effect is a side benefit of financing a car you need, not a reason to borrow. This page explains how a car loan shows up in each part of your credit file, who gains most, and what goes wrong. It is one of our credit score guides; the score a lender looks for when you apply is covered in what credit score you need for a car loan.
How a car loan shows up on your credit file
| Part of the file | Effect of a car loan |
|---|---|
| Payment history | Every on-time payment is reported; a payment reported late is a negative item for years. The Financial Consumer Agency of Canada (FCAC) calls payment history “the most important part of your credit score.” |
| Types of credit | Adds an instalment account to a file that may hold only cards. FCAC: “You may have a lower credit score if you only have 1 type of credit product,” and a car loan is one of the examples it gives. |
| Length of history | A new account lowers the average age of your accounts at first, then adds history as it ages. |
| Inquiries | The application adds a hard inquiry. |
| Credit utilization | The loan isn’t revolving credit, so its balance isn’t part of the credit utilization ratio on your cards. |
The loan and its payments are reported to the credit bureaus by the lender; which bureaus depends on the lender. Equifax vs TransUnion explains why your two reports can differ.
Who benefits most
- Thin files. Someone with one or two credit cards and no loans gains a second type of account and a second stream of payments.
- People rebuilding after a bankruptcy, consumer proposal or missed payments, who are adding any positive history they can; rebuilding credit after bankruptcy covers the stages.
- Newcomers. FCAC notes the bureaus “only collect information about your credit activity in Canada,” so history from another country doesn’t appear; credit cards for newcomers covers the card side.
For someone with an established file that already includes loans, the effect is smaller. With no credit history at all, a loan can be hard to get on good terms; how to build credit from scratch and credit-builder loans cover cheaper ways to add an instalment account.
Mistakes that turn it into a problem
- A missed payment. Late or unpaid loan payments can stay on your report for up to 6 years; what happens if you miss a payment explains how late payments are reported. Automatic payments from the start protect against a missed due date.
- Spreading rate shopping out. FCAC: “when shopping for a car loan or mortgage, get quotes from different lenders within a 2-week period. Credit bureaus treat these as 1 inquiry.” Applications spread over several weeks can each count separately; soft vs hard credit checks covers the difference.
- Borrowing more than the budget can carry. A payment that leaves no room for an irregular expense is the likeliest route to a late payment. How much to spend on a car covers sizing the payment to your income, and current rates are compared in car loans in Canada.
- Rolling negative equity into a new loan. FCAC warns that trading in a car worth less than you owe means “you may end up with a larger car loan and more interest to pay”; its page on the financial risks when buying a car works through an example.
Paying it off early
Paying off a loan early saves interest. The account then closes, but its history isn’t lost: FCAC says Equifax keeps closed accounts paid in full on your report for up to 10 years, and TransUnion keeps positive information for up to 20 years. The interest saved is a certain gain, while any credit effect of keeping the loan running longer is hard to measure.
Car loan or lease
A lease is also a credit agreement: car-leasing companies are among the businesses FCAC lists as checking your credit report, so the application counts as an inquiry, and the leasing company can tell you whether it reports the lease to the bureaus. The choice between leasing and buying usually comes down to total cost and how you use the vehicle; lease vs buy a car compares them.
