What a Credit Score Is
A credit score is a three-digit number — typically 300 to 850 — representing your creditworthiness. It tells lenders how likely you are to repay debt based on your history.
Higher scores mean lower risk. This determines whether you are approved for credit and at what interest rate.
The difference between a good and poor score on a 30-year mortgage can amount to tens of thousands of dollars in additional interest paid.
What Determines Your Credit Score
Payment History (approximately 35%): whether you pay bills on time. A single missed payment can drop a good score significantly.
Credit Utilisation (approximately 30%): the percentage of available credit you are using. A $10,000 limit with a $3,000 balance is 30% utilisation. Keep it below 30%. Below 10% is ideal.
Length of Credit History (approximately 15%): how long accounts have been open. Closing old accounts shortens average account age and can reduce your score.
Credit Mix (approximately 10%): having different types — revolving credit like cards and instalment credit like loans.
New Credit Inquiries (approximately 10%): every application creates a hard inquiry that temporarily reduces your score.
How to Check Your Credit Score
In most countries you are entitled to free credit report access annually. In the United States, annualcreditreport.com provides free reports from all three major bureaus.
Check for errors. Incorrect information can unfairly damage your score. Dispute errors with the credit bureau directly.
How to Improve Your Credit Score
Pay every bill on time, every time. Set up automatic minimum payments on every account.
Reduce credit card balances below 30% of limits. Meaningful improvements can appear within one to two billing cycles.
Do not close old accounts. Keep them open with occasional small purchases paid in full.
Avoid multiple credit applications in a short period.
Be patient. Significant score damage takes two to seven years to recover. Consistent positive behaviour over time is the only reliable path to improvement.
Why Credit Score Matters Beyond Borrowing
A strong credit score reduces borrowing costs. In some countries and industries, credit scores are also checked by landlords and employers.
Managing your credit score is about demonstrating financial responsibility — which has real, tangible consequences for the rest of your financial life.
