Credit Scores

What Is a Credit Score?

A credit score is a number that summarises how reliably someone has managed borrowed money in the past. Lenders use it as a quick way to estimate risk before approving a loan, credit card, or other form of credit — a higher score generally signals lower risk to a lender.

What Affects a Credit Score

Different scoring systems weigh factors slightly differently, but most consider similar things:

Factor	Why it matters
Payment history	Consistently paying on time signals reliability
Amount of existing debt	Carrying a lot of debt relative to available credit can signal risk
Length of credit history	A longer, steady track record generally builds more trust
New credit applications	Applying for a lot of new credit quickly can be seen as a risk signal
Mix of credit types	Managing different types of credit responsibly can be viewed positively

Why It Matters to You, Not Just Lenders

A strong credit score isn't just about getting approved — it often unlocks better terms, including lower interest rates. Over the life of a loan, a lower interest rate can mean paying back significantly less overall for borrowing the exact same amount. In some places, credit history can even affect things like renting a home (see understanding a lease).

Worked Example — Two Borrowers

Imagine two people applying for the same loan amount:

• Borrower A has a strong history of on-time payments and manageable debt levels
• Borrower B has a history of missed payments and carries a lot of existing debt

Borrower A is likely to be offered a lower interest rate, since they represent less risk to the lender. Borrower B might still be approved, but at a higher interest rate — or might be declined altogether, depending on how risky the lender judges the situation to be.

Building a Strong Credit History

There's no shortcut to a strong credit score — it's built gradually, mainly through consistent, responsible behaviour:

• Paying bills and any borrowed amounts on time, every time
• Avoiding carrying large balances relative to available credit
• Not applying for lots of new credit accounts in a short period
• Keeping older accounts open and in good standing, since a longer history helps

Common Misunderstandings

A few myths are worth clearing up:

• Checking your own credit report generally does not lower your score — routine checks by yourself are treated differently from a lender's application check.
• Having no credit history at all is not the same as having a great score — some lenders may see no history as harder to judge than a short but positive one.
• A single missed payment isn't necessarily catastrophic, but a pattern of missed or late payments adds up and can be harder to repair.

Key Words

• Credit score — a number summarising how reliably someone has managed borrowed money
• Credit history — a record of past borrowing and repayment behaviour
• Risk — the chance, from a lender's perspective, that a borrower will not repay as agreed
