Credit Score Basics: What Lenders Actually Look At

A credit score is a number generated from the information in your credit file, used to estimate how likely you are to repay. It is calculated, not judged, which means the factors that move it are known and the fastest levers are identifiable. Scores and scale ranges differ by country and by scoring model.

The Inputs And Roughly How They Weigh

Payment history carries the largest weight in most models, commonly around 35 percent. One missed payment can sit on a file for years, so the highest-value action is simply paying every account on time, every month, for at least the minimum.

Amounts owed accounts for roughly 30 percent. This is measured in two ways: total debt relative to total limits, and each card's balance relative to its own limit. Keeping each card under 30 percent of its limit helps; under 10 percent helps more.

Length of credit history is around 15 percent, and it rewards accounts that have been open a long time. Closing an old card can shorten your average account age and reduce total available credit, which is why closing accounts before a mortgage application is usually a mistake.

New credit is around 10 percent and counts hard searches from applications. A cluster of applications within a short window suggests you are struggling to get credit. Mix of credit is the smallest slice, around 10 percent, and rewards a history that includes both revolving credit and instalment loans.

• Payment history - Largest factor. On-time payments on every account, with no defaults or collections.
• Amounts owed - Balance relative to limit per card, and total balances relative to total limits.
• Length of history - Age of your oldest and average account age. Older files score better.
• New applications - Number of recent hard searches. Apply rarely and space applications out.
• Mix of credit - A blend of card and instalment accounts, though weighting is small.

The Fastest Levers

Paying a card down changes the utilisation ratio within one reporting cycle, usually a month. If you owe 2,800 on a 4,000 limit, that is 70 percent used. Paying it to 1,200 takes it to 30 percent, and paying it to 400 takes it to 10 percent. That change can move a score far faster than any other action available to you.

Paying before the statement date rather than the due date also matters, because many issuers report the statement balance. Making a mid-cycle payment reduces the balance that gets reported, even before the account is due.

Correcting errors is the next quickest route. Check your file for accounts that are not yours, balances that were paid off, or late payments recorded in error. Disputing an incorrect entry is free and can remove its effect once the bureau confirms the correction.

What Damages A Score And For How Long

Late payments are the most damaging single event for most people, and the effect fades over time rather than disappearing when the payment is made. The older the missed payment, the less it counts.

Defaults, collections, court judgments and insolvency arrangements weigh heavily and stay on file for years. Timelines differ by country and by type of entry, so check the specific retention period that applies where you live.

High utilisation across several cards creates a compounded effect, since each card is assessed separately as well as together. Maxing one card while others sit idle is worse than spreading the same balance across three cards.

Hard searches reduce a score slightly and recover within months. Multiple applications in a short period stack up, which is why rate shopping for a mortgage should be done in a compressed window and pre-approvals should be used carefully.

Checking And Building

Check your own file at least once a year with the agencies that operate in your country, and check it for free where a statutory free report is available. Your own checks are soft searches and do not affect your score.

Build the file deliberately. Use one card for regular spending, pay the full statement balance each month, and leave older accounts open with small or no balances. Set payment reminders or direct debits for at least the minimum on every account, since an automatic minimum payment protects the payment history factor even if you pay more manually.

Be cautious with credit repair firms that charge for removing accurate information. Accurate negative entries cannot be removed early by a legitimate service, whatever the marketing says. Disputes you can file yourself at no cost cover the same ground.

Finally, treat the score as a symptom rather than a target. It reflects repayment behaviour and debt levels, so the actions that build it, paying on time, keeping balances low and applying rarely, are the same actions that reduce your interest costs.
