Keeping good credit comes down to a handful of habits practiced consistently over time. Your FICO score is built from five categories: payment history (35%), amounts owed (30%), length of credit history (15%), new credit (10%), and credit mix (10%). Once you understand what moves the needle in each category, maintaining a strong score becomes straightforward.
Pay Every Bill on Time
Payment history is the single largest factor in your credit score, accounting for 35% of the total. One late payment reported to the credit bureaus can drag your score down significantly, and the mark stays on your credit report for seven years. The good news is that the impact fades over time, but prevention is far easier than recovery.
Set up autopay for at least the minimum payment on every credit card and loan. This eliminates the risk of forgetting a due date. If you prefer to manage payments manually, use calendar reminders set a few days before each due date. Paying more than the minimum is better for your finances overall, but from a credit score perspective, the critical thing is that no payment arrives 30 or more days late, since that’s the threshold at which most creditors report a delinquency.
Keep Your Credit Utilization Low
The amount you owe relative to your total available credit, called your credit utilization ratio, makes up 30% of your score. People with exceptional scores (800 to 850) carry an average utilization of just 7.1%, according to Experian data. Those in the “good” range (670 to 739) average 38.6%, and people with poor scores tend to use over 80% of their available credit. The pattern is clear: the lower your utilization, the better.
Aim to keep your utilization in the single digits if possible, and definitely below 30%, which is the point where the negative effect on your score becomes more pronounced. Interestingly, 0% utilization is actually slightly worse than 1%, because scoring models need some activity to evaluate. Using your cards lightly and paying them off is the sweet spot.
One detail that trips people up is timing. Card issuers typically report your balance to the credit bureaus at the end of each statement period, not on your payment due date. That means even if you pay in full every month, a high balance could still show up on your report if it’s captured before your payment posts. If you’re preparing for a mortgage application or another situation where your score matters, consider making a payment before your statement closes to lower the reported balance. Most scoring models only look at the most recently reported numbers, so this tactic works quickly.
Keep Old Accounts Open
Length of credit history accounts for 15% of your score. The longer your accounts have been open, the better you look to lenders. Closing an old credit card, even one you rarely use, can hurt you in two ways. First, it shortens your average account age over time. Second, it removes that card’s credit limit from your total available credit, which pushes your utilization ratio higher.
If you have a card with no annual fee that you’ve held for years, keep it open and use it occasionally for a small purchase. A card that sits completely dormant for too long may eventually be closed by the issuer for inactivity. Putting a small recurring charge on it, like a streaming subscription, and setting up autopay keeps the account active with zero effort.
The calculus changes if a card carries a high annual fee you can’t justify. In that case, call the issuer and ask to downgrade to a no-fee version of the card. This preserves the account age and credit limit without the ongoing cost.
Be Strategic About New Credit
Every time you apply for a credit card, mortgage, auto loan, or personal loan, the lender performs a hard inquiry on your credit report. A single hard inquiry typically lowers your score by five to ten points. The impact is temporary, usually fading within a few months, but multiple hard inquiries in a short period can add up and signal to lenders that you’re desperate for credit.
Not every credit check counts against you. Checking your own credit report, receiving pre-approved credit card offers in the mail, and most employer background checks are soft inquiries that don’t affect your score at all. The distinction matters: you should check your own credit regularly without worrying about any impact.
When you do need to shop for rates on a mortgage or auto loan, try to keep your applications within a focused window of about two weeks. Most scoring models treat multiple inquiries for the same type of loan within a short period as a single inquiry, recognizing that you’re rate shopping rather than opening several accounts.
Maintain a Mix of Credit Types
Credit mix accounts for 10% of your score. Scoring models like to see that you can handle different types of credit responsibly. This might include a credit card (revolving credit), an auto loan (installment credit), and a mortgage. Having variety shows lenders you’re experienced with different repayment structures.
That said, never open an account you don’t need just to diversify your credit mix. The benefit is modest compared to the other factors, and taking on unnecessary debt creates real financial risk for a small scoring bump. If you naturally accumulate different account types over the years as you finance a car or buy a home, your mix will take care of itself.
Check Your Credit Reports Regularly
Errors on credit reports are more common than you might expect, and an inaccurate late payment or a balance that doesn’t belong to you can quietly drag your score down. Federal law entitles you to a free credit report every 12 months from each of the three major bureaus (Equifax, Experian, and TransUnion). Beyond that, all three bureaus now let you check your report once a week for free through AnnualCreditReport.com.
Review each report for accounts you don’t recognize, balances that seem wrong, and any late payments that were actually made on time. If you spot an error, contact both the credit bureau and the company that reported the incorrect information. The bureau is required to investigate and respond, typically within 30 days.
Checking your reports on a rotating basis throughout the year, rather than pulling all three at once, gives you more frequent visibility into changes. Many banks and credit card issuers also provide free credit score tracking through their apps, which can alert you to sudden drops worth investigating.
A Quick Reference for Daily Habits
- Autopay minimums on everything. Late payments are the most damaging single event for your score.
- Stay under 30% utilization, ideally under 10%. Pay down balances before statement closing dates when it matters most.
- Don’t close old cards. Use them for a small charge periodically to keep them active.
- Limit hard inquiries. Apply for new credit only when you genuinely need it.
- Review your reports a few times a year. Dispute anything that looks wrong immediately.
Good credit isn’t built through any single action. It’s the result of consistent, boring habits repeated over months and years. The people with 800-plus scores aren’t doing anything exotic. They pay on time, keep balances low, and let their accounts age. The longer you stick with these habits, the more resilient your score becomes.
