Five Factors That Drive Most Scores
Exact weights vary by model, but these ranges apply broadly to many FICO® versions. Use the calculators and tips below to put this into practice.
What is credit?
Credit is a track record of how reliably you borrow and repay money. Lenders, insurers, and even some employers look at this track record to decide approvals, limits, and rates. Your credit reports—kept by Equifax, Experian, and TransUnion—summarize your accounts and history. Your credit score is a number created from those reports.
Scoring models: FICO® vs. VantageScore®
- Used in most mortgage, auto, and many credit card lending decisions.
- Common ranges: 300–850. Newer versions weigh trended data and utilization more precisely.
- Authorized user accounts can help if they’re long, clean, and low utilization.
- Widely offered for free by apps and banks; growing adoption with lenders.
- Also 300–850. Newer versions (4.0) use alternative data and emphasize recent behavior.
- Treats collections paid to $0 more favorably in modern versions.

Smart moves
- Pay on time—set autopay for at least the minimum + use reminders.
- Pay down revolving balances before the statement cuts.
- Keep old, positive accounts open to preserve history.
- Dispute factual errors with clear documentation.
- Add a secured card or credit-builder loan to establish history.
Common mistakes
- Letting utilization spike on reporting day.
- Closing old cards (can shorten age & raise utilization).
- Too many new accounts at once.
- Ignoring small medical bills—can become collections.
- Paying a collector before you validate the debt.

Step 1 — Pull & freeze
Download 3-bureau reports, note every negative item, then freeze credit with each bureau. Create a clean evidence folder for screenshots, letters, and receipts.
Step 2 — Validate & verify
For third-party collections, send a debt validation request to the collector before paying. For bureau disputes, cite specific inaccuracies (dates, amounts, statuses) and attach proof.
Step 3 — Timelines & follow-ups
Bureaus typically have 30–45 days to investigate. Track due dates. If unverifiable or inaccurate, request deletion or correction. Escalate with CFPB complaints when appropriate.
Step 4 — Build positives
Open small, manageable accounts (secured card, credit-builder loan). Keep utilization low and payments on time to strengthen your profile while negatives age.
Frequently Asked Questions
How fast can my score change?
Revolving balances and utilization can impact scores as soon as the next statement reports. Late payments, collections, or major corrections can also move scores quickly once furnished.
Is paying a collection enough to help my score?
Paying a collection can be positive—especially for mortgage underwriting—but some models still consider paid collections negative. When possible, negotiate pay-for-delete in writing.
Should I close old accounts?
Usually no. Closing can raise utilization and shorten age of credit. Consider keeping old, fee-free cards open and using them lightly.
How many cards should I have?
Enough to keep utilization low and build history without overextending. Many people do well with 2–5 well-managed revolving accounts.
