What factors make up a credit score?

FICO scores are calculated from five factors: Payment History (35%) — whether you pay on time; Credit Utilisation (30%) — how much of your available credit you use; Length of Credit History (15%) — how long your accounts have been open; Credit Mix (10%) — variety of credit types; and New Credit (10%) — recent applications and hard inquiries.

What is a good credit score?

FICO scores range from 300 to 850. Generally: 800–850 is Exceptional, 740–799 is Very Good, 670–739 is Good, 580–669 is Fair, and 300–579 is Poor. Most lenders consider 670+ to be a good score. For the best mortgage and loan rates, aim for 740+.

How can I improve my credit score quickly?

The fastest ways to improve your score are: pay all bills on time, reduce credit card balances to below 30% of limits (ideally below 10%), avoid applying for new credit unless necessary, keep old accounts open to maintain credit history length, and check your credit report for errors to dispute.

How long does it take to improve a credit score?

Minor improvements (e.g. paying down balances) can show within 1–2 months. Recovering from late payments typically takes 12–24 months of positive behaviour. Bankruptcies and defaults can take 7–10 years to fully fall off your report, though their impact reduces over time.

Credit Scores: What Actually Moves the Number

Built and verified by Andrius R. · Updated June 2026

A credit score is a prediction dressed as a grade: a statistical estimate of how likely you are to miss payments in the next couple of years. Knowing the recipe — and the myths around it — turns an opaque number into something you can deliberately steer.

The FICO recipe

Factor	Weight	What it means in practice
Payment history	35%	Pay every account on time, every time. One 30-day late mark can cost a good score dearly and lingers up to 7 years
Amounts owed (utilization)	30%	Balances relative to limits — the fastest lever you control
Length of history	15%	Average and oldest account age; rewards patience
New credit	10%	Recent applications; several in a short window looks like distress
Credit mix	10%	Experience with both revolving (cards) and installment (loans) credit

FICO scores run 300–850; common bands: 580–669 fair, 670–739 good, 740–799 very good, 800+ exceptional. (VantageScore weighs things slightly differently; UK agencies use entirely different scales — the factors above transfer even where the numbers don't.)

Utilization: the fast lever, worked through

Worked example

A $500 balance reported on a $2,000-limit card = 25% utilization. Common guidance: stay under ~30%; the highest scorers typically sit in single digits. Two non-obvious mechanics: utilization is usually computed from the balance on your statement date — you can pay in full monthly and still "look" maxed out if the statement cuts at your peak — and it has little memory, so high utilization stops hurting almost as soon as a lower balance reports. Paying a card down mid-cycle, or requesting a limit increase you don't spend, can move this factor within one or two statements.

The myths, corrected

"Carrying a balance builds credit." False — and expensive. Paying in full reports exactly as positively, with zero interest. The myth confuses using credit with owing on it.
"Checking my score hurts it." Checking your own score is a soft inquiry: no effect. Only applications (hard inquiries) ding it, modestly and temporarily — and scoring models count multiple mortgage/auto inquiries within a shopping window as one.
"Closing old cards helps." Usually the opposite: closing removes its limit (raising utilization) and eventually shortens your history. An old no-fee card is often worth keeping open with a tiny recurring charge.
"Income affects the score." It doesn't appear in the formula at all — lenders consider income separately. A modest earner with clean habits can out-score a high earner with late payments.

An honest improvement timeline

Utilization fixes show in 1–2 statement cycles. Hard-inquiry dents fade within months. Late payments hurt less as they age but remain visible up to 7 years — the system forgives gradually, not instantly. The compounding habits: 100% on-time payments (automate minimums as a safety net), utilization low, old accounts open, applications spaced out. Boring, mechanical, and effective — and the payoff is concrete: the rate gap between a fair and an excellent score on a mortgage or personal loan is worth thousands, as the worked examples on those pages show.

How Credit Scores Are Calculated

FICO scores — the most widely used credit scores — range from 300 to 850 and are calculated from five weighted factors. This estimator uses the same weights to give you a rough indication of your score range based on your answers.

Factor	What it measures	Weight
Payment History	On-time payments vs missed/late	35%
Credit Utilisation	Credit used ÷ credit available	30%
Credit History Length	Age of oldest and newest accounts	15%
Credit Mix	Variety of credit types held	10%
New Credit	Recent hard enquiries and new accounts	10%
