How Credit Scores Are Calculated
FICO scores — used in over 90% of lending decisions — are calculated using five factors. Understanding the weight of each factor tells you exactly where to focus your effort.
| Factor | Weight | Best For | Key Action |
|---|---|---|---|
| Payment History | 35% | Biggest single impact | Never miss a payment — set autopay |
| Credit Utilization | 30% | Fastest wins | Keep utilization below 10% per card |
| Credit Age | 15% | Long-term strategy | Keep oldest cards open; don't close |
| Credit Mix | 10% | Adding an installment loan | Have both revolving and installment credit |
| New Inquiries | 10% | Avoid applying often | Space new credit applications 6+ months apart |
Improve Payment History: The Single Biggest Factor
Payment history makes up 35% of your FICO score. A single 30-day late payment can drop your score 60–110 points, and it stays on your report for 7 years. This is the most important habit to build.
Steps to perfect payment history:
- Set autopay for the minimum on every account — this ensures you never miss a payment due to forgetfulness
- Pay above the minimum manually when you can afford it
- If you already have a late payment, call the creditor and request a goodwill deletion — many will remove one late payment for long-standing customers
- Dispute late payments that aren't yours via the CFPB's dispute process
Lower Credit Utilization: The Fastest Way to Raise Your Score
Credit utilization — the percentage of your credit limit you're using — accounts for 30% of your score. The difference between 30% utilization and 10% utilization can be worth 50–80 points.
Proven strategies to lower utilization:
- Pay down balances before the statement closing date, not just the due date. Your balance is reported to bureaus on the closing date.
- Request a credit limit increase. If your balance stays the same but your limit goes up, your utilization ratio drops. This works best if you've had the card 6+ months and have good payment history.
- Spread balances across cards. Having one card at 80% utilization hurts more than having four cards at 20% each.
- Make multiple payments per month to keep the reported balance low.
Dispute Credit Report Errors
According to a Federal Trade Commission study, 1 in 5 consumers has an error on at least one of their credit reports. Errors that lower your score include: accounts that don't belong to you, incorrect balances, accounts listed as open that are closed, and late payments that were on time.
How to dispute errors:
- Pull your free credit report from all three bureaus at AnnualCreditReport.com
- Identify errors and gather documentation
- File disputes with each bureau that shows the error (Equifax, Experian, TransUnion)
- Bureaus must investigate within 30 days
- If the disputed item can't be verified, it must be removed
Build Credit Fast: The Best Strategies
If you're starting from scratch or rebuilding after damage, here are the fastest legitimate paths to better credit:
- Secured credit card: Deposit $200–$500, use it for small purchases, pay in full each month. Most secured cards report to all 3 bureaus and convert to unsecured after 12–18 months.
- Credit builder loan: A loan where your payments are held in escrow and reported to bureaus. You get the money at the end. Typical cost: $6–$10/month. Typical score improvement: 35–60 points in 12 months.
- Become an authorized user: Ask a family member with good credit to add you to their oldest, lowest-utilization card. That account's history is added to your report instantly.
- Experian Boost: Free program that adds on-time utility and streaming payments to your Experian report. Average boost: 13 points.
Frequently Asked Questions
How long does it take to improve your credit score?
Small improvements (paying down a balance, disputing an error) can appear in 30–45 days. Significant rebuilding from a low score typically takes 6–12 months of consistent positive behavior. Removing a collection account or late payment can cause a 40–100 point jump within one billing cycle.
Does checking your own credit score hurt it?
No. Checking your own credit is a soft inquiry and has zero impact on your score. Only hard inquiries — when a lender checks your credit in response to a new credit application — affect your score, typically by 5–10 points for 12 months.
What is a good credit score?
FICO scores range from 300–850. Generally: below 580 is poor, 580–669 is fair, 670–739 is good, 740–799 is very good, and 800+ is exceptional. For the best mortgage rates, aim for 760+. Most lenders approve auto loans at 660+.
Should I close old credit cards I don't use?
Usually no. Closing an old card reduces your total available credit (raising utilization) and can lower your average account age, both of which hurt your score. Instead, make one small purchase per year to keep the account active, then pay it off immediately.
