Home › Guides › Credit Score Basics: What It Is and How to Improve It
CreditYour credit score is a three-digit number that quietly prices almost every loan you will ever take. A 100-point difference can mean paying tens of thousands more in interest on a mortgage — or being rejected outright.
This guide explains what the score measures, the five factors behind it (with their weights), what damages it most, and the legitimate, proven ways to raise it — plus the myths you can safely ignore.

What a credit score actually is
A credit score (typically 300–850, e.g. FICO) predicts the likelihood you will repay borrowed money. Lenders use it to decide whether to lend and at what price. Landlords, insurers and even some employers check versions of it.
Rough bands: 800+ exceptional, 740–799 very good, 670–739 good, 580–669 fair, below 580 poor. Crossing from "good" to "very good" is where the best mortgage rates unlock — often worth 0.5%+ off your rate.
The five factors (and their weights)
| Factor | Weight | What it means |
|---|---|---|
| Payment history | ~35% | Paying on time, every time — the single biggest factor |
| Amounts owed (utilization) | ~30% | How much of your credit limits you use |
| Length of history | ~15% | Age of accounts; older is better |
| Credit mix | ~10% | Variety: cards, instalment loans, mortgage |
| New credit | ~10% | Recent applications and new accounts |
The top two factors control nearly two-thirds of your score. Master on-time payments and low utilization and you have mastered the score.
What hurts your score most
- Missed payments — a single 30-day late can cost 60–100+ points; the more recent and severe, the worse.
- High utilization — using 90% of a card limit signals distress even if you pay in full. Keep reported utilization under 30%, ideally under 10%.
- Collections, defaults, bankruptcy — these linger for up to 7–10 years.
- Closing old cards — shortens your history and raises utilization by removing available credit.
- Rapid-fire applications — several hard inquiries in a short window (outside rate-shopping) look desperate.
Proven ways to raise your score
- Automate every minimum payment. Payment history is 35% — autopay makes it bulletproof.
- Pay cards down before the statement date. Utilization is measured on reported balances; paying early keeps it low.
- Ask for limit increases (without a hard inquiry if possible) — same spending, lower utilization.
- Keep old cards open — put a small recurring charge on them to keep them active.
- Dispute errors. Roughly 1 in 5 reports has an error; a wrongly reported late payment can be removed.
- Become an authorized user on a responsible person's old card — their history can boost yours.
Expect meaningful movement in 3–6 months of consistent behavior; major damage takes 12–24+ months to fade.
Myths to ignore
- "Carrying a balance helps." False — paying in full helps exactly as much and costs nothing. Never pay interest to "build credit."
- "Checking my score hurts it." False — personal checks are soft inquiries with zero impact.
- "Closing cards helps." Usually hurts, via utilization and history length.
- "You need debt to have a score." You need credit history, which a single card paid in full builds perfectly.
Frequently asked questions
Small wins (lowering utilization) can lift your score within one or two billing cycles. Recovering from missed payments takes 12–24 months of clean history, and serious items like collections fade over several years. Consistency matters more than tricks — there are no legitimate overnight fixes.
No. Checking your own score is a "soft inquiry" and never affects it. Only "hard inquiries" — when a lender checks because you applied for credit — have a small, temporary impact of a few points.
Minimums vary, but conventional loans typically want 620+, with the best rates reserved for 740+. FHA-style programs may accept lower scores with bigger down payments. Because rate pricing is tiered, even a 20-point improvement near a threshold can save thousands.
Yes — you need credit history, not debt. One credit card used lightly and paid in full each month builds an excellent score over time. The scoring models reward responsible use of available credit, not the interest you pay.
