Credit and debt

Borrowing money you repay later, usually with interest.

Read

Borrowing now, paying later

Credit lets you buy something now and pay later. When you use credit, you take on debt: money you owe.

Credit is a tool. Used wisely, it helps you buy a home, pay for school or handle emergencies. Used carelessly, interest can make debt grow quickly.

Types of credit

Type How it works Example
Credit card revolving: borrow and repay up to a limit everyday purchases
Line of credit borrow as needed up to a limit, usually lower interest home repairs
Instalment loan fixed amount repaid in regular payments car loan, student loan
Mortgage long-term loan secured by a home buying a house
Buy now, pay later split a purchase into instalments online shopping

The cost of credit

The interest rate decides how much borrowing costs.

Credit Typical interest rates
Mortgage about 4–7%
Car loan about 5–10%
Line of credit about 7–12%
Credit card about 20–30%
Payday loan very high, often equivalent to several hundred percent a year

Example: $2,000 on a credit card at 20% per year, unpaid for a year, costs about $400 in interest.

Good debt vs bad debt

  • Good debt may build value: education, a home, tools for a business.
  • High-interest debt for things that lose value quickly (impulse purchases, vacations on a credit card) is usually considered bad debt.

Your credit score

In Canada, a credit score ranges from 300 to 900. Higher is better. Lenders use it to decide whether to lend and at what rate.

Factor Effect
Paying bills on time the biggest factor
Credit used vs available using less than about 30% of your limit helps
Length of credit history longer is better
New applications many in a short time can lower your score
Mix of credit types a mix can help a little

Your credit report is kept by credit bureaus (Equifax and TransUnion in Canada). You can request it for free.

The debt trap

Paying only the minimum on a credit card can take years and cost a lot. If debt grows faster than you can pay, talk to the lender or a non-profit credit counsellor early.

Worked examples

Example 1: A $1,500 limit with a $600 balance. Utilization? 600 ÷ 1,500 = 40% (higher than the suggested 30%).

Example 2: A $10,000 car loan at 6% simple interest for 3 years. Interest? $1,800.

Example 3: Which hurts a credit score more: a late payment or checking your own score? A late payment (checking your own score doesn’t affect it).

Common mistakes

  • Missing payments, which damages your score.
  • Using credit cards for money you don’t have.
  • Taking payday loans, which are extremely costly.

Try it yourself

  1. Range of Canadian credit scores?
  2. $3,000 limit; keep usage under 30%. Maximum balance?
  3. Name two types of credit.
  4. What is the most important factor in a credit score?

Answers: 1) 300–900 2) $900 3) e.g. credit card, car loan 4) paying on time

Quick recap

  • Credit creates debt that must be repaid with interest.
  • Compare interest rates; credit cards are costly.
