A credit score is a number that summarizes your track record of borrowing and repaying money. Lenders, landlords and sometimes employers use it as one input when deciding whether to extend credit — and on what terms.
What feeds into a credit score
While exact formulas are proprietary and vary by country and provider, scoring models generally weigh similar factors: payment history (paying on time), amounts owed relative to available credit, length of credit history, types of credit used and recent applications for new credit. A long history of on-time payments with modest balances typically scores best.
How scores are used
Lenders use scores to estimate risk. A higher score usually means access to credit at lower interest rates; a lower score can mean higher rates, larger deposits or declined applications. Scores are one factor among many — income, employment and existing debts also matter.
Credit systems differ by country
Credit scoring is not the same everywhere. The United States has a well-established bureau system with widely used scoring brands; the United Kingdom has multiple credit reference agencies with their own scales; Canada, Australia and New Zealand each run their own bureau systems with different score ranges and rules. New arrivals in a country often start with no local credit history at all, regardless of their record elsewhere.
General habits that support a healthy score
Commonly recommended habits include paying every bill by its due date, keeping card balances low relative to limits, avoiding many applications in a short period, and checking your own report periodically for errors. Building history takes time — there are no legitimate shortcuts.
