# Credit Score Management

## When to use this skill
Use when the user says things like:
- "How can I boost my credit score?"
- "Explain my credit report."
- "What factors affect my credit score?"
- "Give me a plan to improve credit utilization."
- "How do I prepare for a mortgage with better credit?"


## Core Philosophy
A credit score is a numerical summary of borrowing behavior that lenders use
to assess risk. Understanding how scores are calculated and what actions move
them up or down empowers better financial decisions. The goal is not to obsess
over the number but to build habits that naturally produce strong credit,
which in turn unlocks lower interest rates, better insurance premiums, and
more favorable terms on major financial commitments.

## Key Techniques
- **Payment History (35%)**: Pay every bill on time, every time. Even a single
  30-day late payment can drop a score significantly and remains on the report
  for seven years.
- **Credit Utilization (30%)**: Keep revolving credit usage below 30% of
  available limits, and below 10% for the best scores. This is calculated
  both per-card and across all revolving accounts.
- **Length of Credit History (15%)**: Keep oldest accounts open even if rarely
  used. Closing old cards shortens average account age and can reduce scores.
- **Credit Mix (10%)**: A healthy mix of revolving credit (cards) and
  installment loans (mortgage, auto, student) demonstrates ability to manage
  different types of debt.
- **New Credit Inquiries (10%)**: Limit hard inquiries by applying for new
  credit only when needed. Multiple inquiries for the same loan type within
  a short window are typically treated as a single inquiry.

## Best Practices
- Check credit reports from all three bureaus at least annually through
  AnnualCreditReport.com. Dispute any errors promptly.
- Set up autopay for at least the minimum payment on all accounts to prevent
  accidental late payments.
- Request credit limit increases periodically to improve utilization ratios
  without increasing spending.
- Become an authorized user on a family member's long-standing, well-managed
  credit card to inherit its positive history.
- Avoid closing credit cards before applying for a mortgage or other major
  loan, as the reduced available credit increases utilization.
- Use credit monitoring services to receive alerts about changes and potential
  fraud.
- Time major credit applications strategically, spacing them out and avoiding
  applications in the months before a mortgage application.

## Common Patterns
- **The Score Builder**: For those starting from no credit, begin with a
  secured credit card or credit-builder loan, use it lightly, and pay in full.
- **The Recovery Plan**: After a credit setback, focus on consistent on-time
  payments, reducing balances, and allowing negative items to age off.
- **The Optimization Sprint**: Before a major loan application, pay down
  utilization, dispute errors, and avoid new inquiries for maximum score.
- **The Maintenance Mode**: Once scores are strong, maintain habits with
  minimal effort through autopay and occasional monitoring.

## Anti-Patterns
- Carrying a balance to build credit. Paying in full each month builds credit
  equally well and avoids interest charges entirely.
- Closing unused cards to simplify finances without considering the impact on
  utilization ratio and average account age.
- Obsessively checking scores through services that trigger hard inquiries
  rather than using free soft-pull monitoring tools.
- Applying for multiple credit cards in a short period to earn sign-up bonuses
  without understanding the cumulative effect on scores.
- Ignoring credit reports until a loan application reveals errors or fraud
  that could have been caught and resolved earlier.
- Co-signing loans without understanding that the debt appears on your report
  and any missed payments damage your credit.
