Many people discover their score has dropped or isn’t where it should be when applying for a credit card, loan, or mortgage. The good news is you can usually fix it—once you know what’s behind the number.
Below, we break down the most common reasons credit scores fall, the impact each factor has, and how to fix it step-by-step. Whether you're trying to qualify for a better interest rate, a premium rewards card, or a home loan, improving your credit score can lead to real savings.
A credit score—typically ranging from 300 to 850—is a snapshot of your financial reliability. Here’s what tends to bring it down:
Your payment history makes up about 35% of your FICO score. Even a single missed or late payment on a credit card, personal loan, or utility bill can knock your score down by 90–110 points.
Fix:

This refers to how much of your available credit you're using. If you're using more than 30% of your total credit limit, it can significantly lower your score.
Fix:
Example: If you have a $10,000 limit and owe $5,000, your utilisation is 50%—which is too high. Paying it down to $2,000 (20%) can boost your score within 30 days.
Each time you apply for credit (credit cards, car loans, mortgages), the lender checks your credit—this is a hard inquiry. Multiple inquiries within a short time can lower your score.
Fix:
Length of credit history makes up 15% of your score. If you're new to credit or have recently opened several accounts, your score might be lower even without missed payments.
Fix:
If a lender writes off your debt or sends it to collections, your score can drop drastically. Even paid collections can hurt if they’re recent.
Fix:
These are severe and long-lasting score killers. A bankruptcy can drop your score by 150–200+ points and remain on your report for up to 10 years.

If you spot an error, file a dispute with the bureau that reported it. Errors are more common than most people realise.
This is the fastest and most effective way to start improving your score. Set up autopay or use budgeting apps to stay on track.

Cards like the Discover it® Secured or Capital One Platinum Secured report to all three bureaus and can help you build history if you’re starting from scratch or recovering from a low score.
Available from online lenders or local credit unions, these loans are designed to help you build or repair credit. You make monthly payments into a locked savings account, then get the money (and a better score) at the end.
If you have a good payment history with your card issuer (like Chase, Citi, or Bank of America), request a higher limit. It lowers your utilisation and can increase your score.
Being added to someone else's card (such as a parent or spouse) with a good credit history can help your score. Make sure the issuer reports authorised users (most major banks do).
If your score is below 600, start with cards that are designed for rebuilding:
Discover it® Secured Credit Card
Capital One Platinum Secured
Chime Credit Builder Visa®
These cards require a refundable deposit but are easier to get approved for, even with bad credit.
Improvement can start in as little as 30 days if you reduce credit utilisation or remove errors. That said:
A 100-point gain in 6 months is very possible with the proper steps.
To improve a low credit score, start by checking your credit reports for errors and paying all bills on time. Focus on reducing credit card balances and avoiding unnecessary credit applications. Use tools like secured cards or credit builder loans to rebuild your credit profile. Be consistent—small actions lead to steady gains. Compare options from trusted issuers like Capital One, Discover, or Chime to take the next step toward stronger credit.
