Knowing how to keep good credit is just as important as building it. A 720 score can drop 60 points in a single missed payment, and rebuilding may take 12 months or longer. Once your score crosses into the good range (670+) or excellent range (740+), the goal shifts from growth to protection.
This guide walks through the seven habits that may keep your score steady and your loan rates low for years.
Know What Actually Drives Your FICO Score
Your FICO score is built from five factors. Each one carries a different weight, so your effort should match the math.
- Payment history: 35%
- Credit utilization: 30%
- Length of credit history: 15%
- Credit mix: 10%
- New credit: 10%
Together, payment history and utilization make up 65% of your score. Most maintenance work should focus on those two areas. The rest matters, but small changes there move your score less.
Pay On Time, Every Time
Payment history is the single biggest factor. Just one 30-day late payment may drop a 750 score by 60 to 100 points and stay on your report for up to seven years.
The fix is simple, but it takes a system. Set autopay for at least the minimum on every card and loan. Use calendar reminders three days before each due date so you can confirm there is enough cash in the account.
If you ever miss a due date, call the issuer that same day. Many will reverse a single late fee and may delay reporting if you pay within 30 days. After 30 days, the late mark hits your report and there is no easy reversal.
Keep Utilization Low
Credit utilization is the percentage of your total revolving credit that you are using. If you have $10,000 in card limits and a $4,000 balance, your utilization is 40%. That is too high.
Aim for under 30% on every card, ideally under 10%. Even people with excellent credit see a small dip when utilization briefly spikes above 30%, like the month after a big trip.
Two tricks may help. First, pay your card down before the statement closes, not just before the due date, since the statement balance is what gets reported. Second, ask for a credit limit increase every 6 to 12 months. A higher total limit lowers your ratio without you spending less.
Keep Your Oldest Card Open
The age of your accounts is 15% of your score. Closing your oldest card may shorten your average account age and trigger a score drop, even if everything else is perfect.
If your oldest card has no annual fee, keep it open and use it for one small recurring charge, like a streaming subscription, with autopay set. That small activity keeps the account from going dormant and helps it stay on your report.
If the card has an annual fee you do not want to pay, ask the issuer to convert it to a no-fee version. Many large banks allow this product change without losing your account history.
Avoid Hard Inquiry Clusters
Each new credit application creates a hard inquiry, which may shave a few points off your score for up to a year and stay on your report for two years.
A single inquiry is no big deal. Several in a short window can be. Opening three new cards in two months looks risky to lenders and may signal cash flow problems, even if you are simply chasing rewards.
There are exceptions. Multiple mortgage, auto, or student loan inquiries within a 14 to 45 day window are usually treated as one inquiry for FICO purposes. So shopping for the best rate on a single loan is fine. Stacking applications across different product types is the issue.
Monitor Your Reports Regularly
About 1 in 5 consumers find errors on their credit reports each year. Errors may include accounts that are not yours, paid debts still showing as unpaid, or wrong limits and balances.
Check all three bureaus at AnnualCreditReport.com, where you can pull free reports weekly. Free monitoring services may also alert you to new accounts, balance jumps, and hard inquiries in real time.
Dovly offers a free tier that monitors your reports and may help dispute errors automatically. Catching issues early is much easier than fixing them later, and quick disputes may help protect your score within 30 to 45 days.
Keep a Healthy Credit Mix
Credit mix is 10% of your score. Lenders like to see that you can handle different types of credit, including revolving lines like cards and installment loans like auto, student, or personal loans.
You should not open new accounts just to chase mix. But if your file is mostly cards, adding a small installment account may help. A credit-builder loan is one of the lowest-risk ways to add an installment tradeline.
The Self Inc Credit Builder Account is a popular pick. You make small monthly deposits to a CD-style account, and Self reports those deposits to all three bureaus as installment payments. Pairing it with the Self Visa Credit Card may add both card and loan tradelines to your file.
The Current Build Card and OpenSky are other tools that may help on the revolving side, especially if you want to keep a clean second card open for utilization control.
Plan Big Purchases Ahead of Time
A big purchase like a mortgage, refinance, or auto loan usually triggers a hard inquiry and may lower your score for a few months. The smart move is to time your applications.
Avoid opening new cards or running up balances in the 90 days before a major loan application. Keep utilization low across all cards and pay down any creeping balances. APRs vary by creditworthiness, so even a 20-point score swing may change the rate you receive.
After closing on a big loan, give your file 6 months to settle before adding new credit. That cool-off period may help your score bounce back faster.

Frequently Asked Questions
How quickly can good credit drop?
Very quickly in some cases. A single 30-day late payment may drop a 750 score by 60 to 100 points within one billing cycle. High utilization or a charge-off may cause similar drops. Recovery can take 6 to 24 months of clean activity.
Should I close credit cards I no longer use?
Usually no. Closing a card may shorten your average account age and raise your utilization ratio, both of which may hurt your score. Keep no-fee cards open with a small recurring charge on autopay so they stay active.
How often should I check my credit?
Pull all three bureau reports at AnnualCreditReport.com at least once every 4 to 6 months. Use a free monitoring service for real-time alerts on new accounts and balance changes. Frequent checks do not hurt your score, since they are soft inquiries.
Does paying off a loan early hurt my credit?
It can cause a small temporary dip, especially if it was your only installment account. The long-term effect is usually positive, since you save interest and free up income. Terms and conditions apply on early payoff for some loans.
