Credit Score: What It Is and Why It Matters

Ever wonder why lenders ask for a three‑digit number before approving a loan or credit card? That number is your credit score, and it’s basically a report card for how you handle money. A higher score can shave years off a mortgage, lower an auto loan rate, or unlock premium credit‑card rewards. A lower score can mean higher fees or outright denial. Understanding the score is the first step to improving it.

How Scores Are Calculated

Credit bureaus look at five main factors. Payment history makes up about 35 % – missed payments or defaults drop you fast. Amounts owed, or credit utilisation, is the next biggest slice; using more than 30 % of your available credit can hurt. Length of credit history matters too – older accounts show stability. New credit inquiries add a small bump, and finally, the mix of credit types (credit cards, mortgages, loans) rounds things out. Each factor is weighted, so a single late payment can outweigh years of good behaviour.

Practical Steps to Raise Your Score

First, set up automatic payments for any bill that shows up on your credit report. On‑time payments are the easiest win. Second, check your utilisation. If you have a £5,000 limit, try to keep the balance under £1,500. If you can, ask the card issuer for a higher limit – that lowers the ratio without you spending more. Third, keep old accounts open. Even if you don’t use a card, its history helps the length‑of‑credit factor.

Fourth, clean up errors. Pull your free credit report once a year and dispute any wrong entries. A single mistaken late payment can shave dozens of points. Fifth, avoid opening several new accounts at once. Each hard inquiry drags the score down a little, and the “new credit” factor can look risky to lenders.

If you’re aiming for the elite club of an 800‑plus score, know it’s rare. According to our “How Rare Is an 800 Credit Score?” post, less than 5 % of borrowers hit that mark. Reaching it typically requires years of spotless payment history, low utilisation (<10 %), and a diverse credit mix.

For those with a solid 750 score, the upside is clear: our “Car Loan Interest Rates for 750 Credit Score in 2025” article shows you can snag rates around 4‑5 % on a new auto loan, versus 6‑7 % for lower scores. That difference saves hundreds over the life of the loan.

Planning to apply for several credit cards? Remember the 2‑3‑4 rule mentioned in the “2 3 4 Rule for Credit Cards” guide. Banks often flag multiple applications within a short window, treating them as risky. Space out applications – three months apart – and stick to two or three cards max in a year to keep approval odds high.

Finally, be patient. Credit scores update in cycles, usually every 30 days. Small improvements add up, and the gap between a 680 and a 720 can mean a dramatically better loan offer. Keep tracking, stay disciplined, and watch your score climb.
