Saving, Investing, and Borrowing

MEL3E study topic: B3.6

Imagine two people apply for the same phone plan or loan. A company may review each person’s credit history before deciding what terms to offer. Credit information does not tell the whole story about a person, but it can help a lender judge the risk of lending money. In this lesson, you will learn what credit ratings mean and why they matter.

What you will learn

Explain what a credit rating tells a lender.
Recognize common Canadian credit-rating codes.
Describe how a credit rating may affect borrowing and other decisions.
Identify habits that can help build a positive credit history.

1. Credit history, reports, and scores

Credit is money or a service that you receive now and agree to pay for later. A credit card and a loan are examples. When you use credit, companies may send information about your account and payments to a credit bureau. A credit bureau is an organization that collects and keeps credit information.

A credit report is a record of credit accounts and payment history. It may show whether payments were made on time, how much is owed, and whether an account was sent to collections. Collections means a company is trying to collect an unpaid debt, sometimes through another agency.

A credit score is a number calculated from information in a credit report. A credit rating is a description or code about how an account is being paid. People sometimes use these terms as if they mean the same thing, but they are not identical. A lender may consider a score, account ratings, income, and other information when reviewing an application.

A credit report contains credit information.
A credit score is a number based on credit information.
An account rating describes payment status for that account.

2. Reading common account-rating codes

In Canada, account ratings can use a letter and a number. The letter describes the type of credit. For example, R is commonly used for revolving credit, such as a credit card. I is commonly used for installment credit, such as a loan repaid in regular payments. The number describes payment history or account status.

For many R-rated accounts, a lower number generally indicates a stronger payment record. R1 means the account is paid as agreed, usually within the time allowed by the lender. R2 and higher numbers indicate increasing delays or more serious account problems. R9 is used for a very serious status, such as an account written off as a bad debt, sent to collections, or included in bankruptcy. Exact reporting details can depend on the account and the credit bureau.

An account rating is not the same as a promise that a lender will approve or refuse an application. A lender reviews the full situation and uses its own rules. A rating is one piece of information.

The letter points to the kind of credit account.
The number gives information about the account’s payment status.
A rating does not guarantee a particular lending decision.

3. Consequences and responsible choices

A strong record of paying as agreed can help show that a person manages credit reliably. A lender may be more willing to approve an application or offer better terms. Better terms could include a lower interest rate, which is the cost charged for borrowing, or a higher credit limit. Approval and terms are never guaranteed by a rating alone.

Late payments and unpaid debts can make a credit record less positive. A lender may refuse an application, approve a smaller amount, charge a higher interest rate, or ask for added security or a co-signer. A co-signer agrees to repay the debt if the borrower does not. A landlord, phone provider, or other company may also review credit information when deciding whether to offer a service or require a deposit. Practices differ, and not every company checks credit.

A person can support a positive history by paying bills by the due date, borrowing only what they can repay, and checking account statements for mistakes. If a report seems wrong, the person can contact the credit bureau and the company that supplied the information to ask how to dispute it. Building a record takes time; one late payment does not by itself explain every lender’s decision.

Credit information can affect approval, borrowing cost, limits, deposits, or requests for a co-signer.
Companies make their own decisions; a rating is not the only factor.
On-time payments and checking for errors are useful habits.

A simple guide to common R ratings

Code	General meaning
R1	Paid as agreed, usually within the time allowed
R2	Payment is more than 30 days late
R3	Payment is more than 60 days late
R4	Payment is more than 90 days late
R9	Very serious status, such as bad debt, collections, or bankruptcy

Worked example

Example 1: Comparing two account records

Mina’s credit report lists a credit-card account as R1. Devon’s report lists a credit-card account as R3. What can you reasonably say about the difference, and what should you avoid assuming?

Identify the account type
Both codes begin with R, so both refer to revolving credit, such as a credit card.
Compare the numbers
R1 usually shows payment as agreed. R3 indicates a more delayed payment record than R1. The code points to account history, not to a complete picture of either person.
State a careful conclusion
A lender might view Mina’s account record more positively. But you cannot know from these codes alone whether either person will get a loan, what rate they will be offered, or what their overall credit score is.

Answer: Mina’s R1 account generally shows a stronger payment record than Devon’s R3 account. The codes alone do not determine approval or loan terms.

Check: The conclusion compares the account ratings without treating them as a guaranteed lending decision.

Worked example

Example 2: Explaining a loan decision

A credit union tells Jordan that a loan application was approved, but at a higher interest rate than the rate offered to some other applicants. Jordan’s report includes an account sent to collections. Explain a possible connection without claiming it is the only reason.

Explain the report entry
An account sent to collections is a serious credit-history concern. It may lead a lender to see more risk in lending to Jordan.
Connect risk to the terms
The credit union may have approved the loan but charged a higher rate to account for the risk it judged. A higher interest rate means borrowing costs more over time.
Keep the explanation balanced
The collections entry could have influenced the decision, but it may not be the only factor. The credit union may also consider income, existing debts, and its own lending rules.

Answer: The collections entry may have made the application seem riskier and may help explain the higher rate. It does not prove that this was the only reason for the rate.

Check: The explanation links credit history to a possible consequence while leaving room for other factors.

Common mistakes and how to avoid them

Treating a credit rating and a credit score as the same thing.

Correction: A rating describes an account’s status. A score is a number based on credit information.

Assuming one rating guarantees loan approval or refusal.

Correction: A lender considers the full application and its own rules. A rating is only one part of the decision.

Thinking that every company uses credit information in the same way.

Correction: Companies and lenders have different practices. A credit check may affect a decision, but its effect depends on the situation.

Lesson summary

Credit reports record information about credit accounts and payment history.
Credit ratings describe account status; credit scores are numbers based on credit information.
Less positive credit history may affect approval, interest rates, limits, deposits, or the need for a co-signer.
Paying as agreed, borrowing carefully, and checking reports for errors can support responsible credit use.

Check your understanding

Question 1

A person sees an R1 beside a credit-card account. What is the best interpretation?

The account is generally reported as paid as agreed.
The person is guaranteed a loan at the lowest available rate.
The code is the person’s exact credit score.
correctIndex: 0

Show answer and explanation

The account is generally reported as paid as agreed.

R1 generally describes an account paid as agreed. It is not a score and does not guarantee loan terms.

Question 2

A lender offers someone a higher interest rate after reviewing an application. Which statement is most accurate?

A credit-history concern may be one reason, but other factors may also matter.
The higher rate proves the person has an R9 rating.
All lenders must offer the same rate to every applicant.
correctIndex: 0

Show answer and explanation

A credit-history concern may be one reason, but other factors may also matter.

Credit history may affect terms, but a rate alone does not reveal a rating. Lenders use their own decisions and may consider other information.
