A good credit score starts at 670 on the FICO scale, which is the model most lenders use. Getting there, whether you’re building from zero or climbing from a lower score, comes down to a handful of habits applied consistently over time. Five factors determine your score, and understanding how each one works gives you a clear roadmap for improving it.
What Counts as a Good Score
FICO scores range from 300 to 850. A “good” score falls between 670 and 739, “very good” is 740 to 799, and “exceptional” is 800 and above. VantageScore, the other widely used model, defines “good” as 661 to 780 and “excellent” as 781 to 850. The two models weight factors slightly differently, but the same behaviors improve both. Most credit card approvals, auto loans, and mortgage pre-qualifications use FICO, so that’s the benchmark worth tracking.
Crossing from “fair” into “good” territory can save you real money. On a 60-month auto loan of $30,000, the difference between a 650 score and a 720 score can mean paying thousands less in interest over the life of the loan. Mortgage rate gaps are even larger.
The Five Factors That Determine Your Score
Your FICO score is built from five categories, each with a specific weight:
- Payment history (35%): Whether you pay on time. This is the single biggest factor. Even one payment reported 30 or more days late can drop your score significantly, and the mark stays on your report for seven years.
- Amounts owed (30%): How much of your available credit you’re using, known as your credit utilization ratio. Lower is better.
- Length of credit history (15%): How long your accounts have been open. A longer track record helps.
- New credit (10%): How many accounts you’ve recently opened or applied for. Each application typically triggers a hard inquiry on your report, which can shave a few points off temporarily.
- Credit mix (10%): Whether you have different types of credit, like a credit card and an installment loan. This matters least, so don’t open accounts you don’t need just to diversify.
The first two categories alone control 65% of your score. That’s where your effort pays off the most.
Pay Every Bill on Time, Every Month
Since payment history makes up 35% of your score, this is non-negotiable. Set up autopay for at least the minimum payment on every credit account you have. You can always pay more manually, but autopay ensures you never miss a due date because you forgot or were traveling.
If you’re already behind, getting current helps. A late payment’s damage fades over time, and recent on-time payments matter more than older late ones. After 12 to 24 months of consistent on-time payments, you’ll typically see meaningful recovery.
Keep Your Credit Utilization Low
Credit utilization is the percentage of your available credit you’re currently using across all revolving accounts (credit cards and lines of credit). If you have a card with a $5,000 limit and a $2,500 balance, your utilization on that card is 50%. Scoring models look at both individual card utilization and your total utilization across all cards.
Aim to keep utilization in the single digits for the best score impact. Once you cross 30%, the negative effect becomes more pronounced. Interestingly, 0% utilization is actually slightly worse than 1%, because scoring models need some activity to evaluate your habits. Using your cards lightly and paying them off is the sweet spot.
Here’s a timing detail most people miss: your card issuer reports your balance to the credit bureaus at the end of each statement period, not after you pay. So even if you pay in full every month, a high balance at statement close gets reported as high utilization. To fix this, make a payment before your statement closing date to bring the reported balance down. If you want a simpler approach, estimate your monthly credit card spending, multiply it by 10, and make sure your total available credit across all cards is at least that amount. That keeps your utilization around 10% without requiring you to time payments.
Building Credit When You Have None
If you have no credit history at all, you need to establish accounts that report to the three major bureaus: Equifax, Experian, and TransUnion. Several tools are designed specifically for this.
A secured credit card is the most common starting point. You deposit cash (often $200 to $500), and that deposit becomes your credit limit. You use the card like a regular credit card and make monthly payments. The deposit reduces the issuer’s risk, which is why approval doesn’t require an existing score. After six to twelve months of responsible use, many issuers will upgrade you to an unsecured card and refund your deposit.
Credit builder loans work differently. A bank or credit union sets aside a small loan amount (typically a few hundred to a couple thousand dollars) in a locked savings account. You make fixed monthly payments over six to 24 months, and each payment gets reported to the bureaus. When the loan term ends, you receive the full amount. You’re essentially paying into your own savings while building a payment history.
Becoming an authorized user on someone else’s credit card is another option. When a family member or partner adds you to their account, that card’s history can appear on your credit report. This works best when the primary cardholder has a long history of on-time payments and low utilization. You don’t even need to use the card yourself.
Store credit cards, offered by retailers and gas stations, tend to have lower approval requirements than major credit cards. The credit limits are usually modest, which actually helps you avoid overspending while you build history. Just treat them the same way: use a small amount, pay on time, keep balances low.
Report Rent and Utility Payments
If you’re paying rent, you’re already making a large, regular payment that historically never showed up on your credit report. Rent reporting services change that. You enroll through an app or a service offered by your landlord, link your bank account, and the service reports your rent payments to one or more of the major credit bureaus. Some services will even report up to 24 months of previous payments retroactively, giving you an immediate history boost.
One important detail: some services only report on-time payments, while others report all payments, including late ones. If your rent payments are always on time, either type works in your favor. If you’ve had a late month here or there, look for a service that only reports positive payments. Monthly fees for these services typically run a few dollars to around $10.
Let Your Accounts Age
Length of credit history accounts for 15% of your score, and there’s no shortcut here. The age of your oldest account, the age of your newest account, and the average age of all your accounts all factor in. This is why closing old credit cards can hurt your score even if you no longer use them. Keeping that first card open and occasionally making a small purchase on it preserves your longest account relationship.
This also means you should be selective about opening new accounts. Every new card or loan drops your average account age and adds a hard inquiry. If you already have a solid foundation, only apply for new credit when you have a genuine need.
How Long It Takes
If you’re starting from scratch, most people can generate a FICO score within three to six months of opening their first credit account. Reaching the “good” range of 670 or above typically takes about a year of consistent on-time payments and low utilization, assuming no negative marks.
If you’re recovering from missed payments, collections, or other negative items, the timeline is longer. Late payments affect your score for seven years, though their impact diminishes steadily. Bankruptcies stay on your report for seven to ten years. The good news is that you don’t have to wait for negative marks to fall off before your score improves. Building a thick layer of positive, recent activity gradually outweighs older damage.
Monitor Your Credit Report
You’re entitled to a free credit report from each of the three bureaus every year through AnnualCreditReport.com. Many banks and credit card issuers also provide free score tracking through their apps. Check your reports at least once a year for errors: incorrect late payments, accounts you didn’t open, or wrong balances. Disputing and correcting errors can produce an immediate score improvement if inaccurate negative information was dragging you down.
Monitoring also helps you track your progress. Watching your score respond to lower utilization or a longer payment history reinforces the habits that got you there.
