Most people have never checked their credit score. And even among those who have, many only know the number — not what it actually means, how it is calculated, or what really moves it.
This guide breaks it down properly. You will learn what your credit score represents, how it is calculated, what helps or hurts it, and how to check yours for free.
What is a credit score
A credit score is a three-digit number, typically ranging from 300 to 850, that reflects how reliably you have managed borrowed money.
Lenders use this number to assess risk. The higher your score, the more likely you are to be approved for credit — and at better interest rates.
The most widely used scoring model is the FICO score, developed by the Fair Isaac Corporation. Some platforms use VantageScore, which operates on the same range but applies slightly different weightings.
In most real-world lending decisions, when someone says “credit score,” they are referring to FICO.
The five factors that determine your score
Your credit score is calculated using five core components:
Payment history (35%)
This is the most important factor. Every on-time payment builds your score. Missed or late payments can cause significant damage and stay on your report for years.
Credit utilisation (30%)
This measures how much of your available credit you are using. Keep this below 30 percent, and ideally under 10 percent.
Length of credit history (15%)
Older accounts and longer histories improve your score.
Credit mix (10%)
A mix of credit types (cards, loans, mortgages) strengthens your profile.
New credit (10%)
Each application creates a hard enquiry. Too many in a short period can lower your score.
Score ranges explained
300–579 (Poor)
Most lenders will decline applications or offer very high interest rates.
580–669 (Fair)
Some access to credit, but terms are not favourable.
670–739 (Good)
Access to most mainstream products at reasonable rates.
740–799 (Very good)
Better rates, higher limits, stronger approvals.
800+ (Exceptional)
Top-tier borrowers. Best rates and fastest approvals.
The difference between a poor score and an exceptional score can cost — or save — tens of thousands over the life of a mortgage.

What hurts your credit score
Missing payments
Even one missed payment can stay on your report for up to seven years.
High utilisation
Maxing out cards increases your utilisation, even if you pay in full later.
Closing old accounts
Reduces available credit and shortens account history.
Multiple applications
Too many hard enquiries signals risk to lenders.
Collections
Unpaid debts that go to collections cause significant damage.
Co-signing loans
You take on someone else’s risk.
