Your credit score influences the interest rate you pay on mortgages, auto loans and cards, and can affect insurance pricing and rental approvals.
The five FICO factors
Payment history is roughly 35% of a FICO score, amounts owed or utilization about 30%, length of credit history 15%, new credit 10% and credit mix 10%. These weights are approximate and vary by individual file.
Ways to improve your score
Pay every bill on time, even if only the minimum. Keep revolving utilization below 30%, and ideally under 10%. Avoid closing your oldest accounts. Limit hard inquiries. Check your reports free at AnnualCreditReport.com and dispute errors.
How long changes take
Utilization changes can appear within one or two billing cycles. Late payments can linger for seven years, but their impact fades over time. Building history takes patience; there is no legitimate quick fix, and companies promising one are likely scams.
Try the numbers
Use our Debt-to-Income Ratio Calculator to see this in practice. With its default example (Gross monthly income: $7,500; Rent or mortgage: $1,900; Auto loans: $400), it shows back-end dti: 36.67%. Adjust the inputs to match your situation.
Key takeaways
- On-time payments and low utilization matter most.
- Check your credit reports for errors at least once a year.
- Avoid scams that promise instant score boosts.
