Understanding Credit Scores

Before we explore common mistakes, it’s essential to understand what a credit score is and how it’s calculated. The most widely used credit score is the FICO score, which ranges from 300 to 850.

Common Credit Score Mistakes

  1. Missing Payments

One of the most detrimental mistakes you can make is missing payments. Your payment history accounts for 35% of your credit score, and even a single missed payment can significantly lower your score.

How to Avoid:

  • Set up automatic payments or reminders to ensure you never miss a due date.
  • Create a budget to manage your expenses and ensure you have enough funds to cover your bills.
  • If you anticipate a late payment, contact your creditor immediately to discuss possible solutions.
  1. High Credit Card Balances

High credit card balances can hurt your credit score due to increased credit utilization. The ideal utilization ratio is below 30%, with 10% or lower being optimal.

How to Avoid:

  • Pay down your balances as much as possible.
  • Consider making multiple payments throughout the month to keep your balance low.
  • Request a credit limit increase to improve your utilization ratio, but avoid increasing your spending.
  1. Closing Old Credit Accounts

Closing old credit accounts can negatively impact your credit score by reducing the average age of your accounts and your total available credit.

How to Avoid:

  • Keep your oldest accounts open, even if you don’t use them frequently.
  • Use older cards occasionally to keep them active and prevent the issuer from closing them.
  • If you must close an account, choose a newer one with a smaller credit limit.
  1. Opening Too Many New Accounts

Opening multiple new accounts in a short period can result in numerous hard inquiries, which can lower your credit score.

How to Avoid:

  • Consider pre-qualification offers that do not affect your credit score.

  1. Not Having a Credit Mix

Having a diverse credit mix can positively impact your credit score. Relying solely on one type of credit, such as credit cards, can limit your score potential.

How to Avoid:

  • If you only have credit cards, consider adding an installment loan, such as a personal loan or auto loan.
  • Manage all types of credit responsibly to build a solid credit history.
  1. Applying for Payday Loans

Payday loans are high-risk, high-interest loans that can signal financial distress to lenders and negatively impact your credit score.

How to Avoid:

  • Avoid payday loans if possible. Seek alternative financing options, such as personal loans from a bank or credit union.
  • Build an emergency fund to cover unexpected expenses.
  1. Defaulting on Loans

Defaulting on any loan, whether it’s a credit card, mortgage, or auto loan, can severely damage your credit score and remain on your credit report for up to seven years.

How to Avoid:

  • Communicate with your lenders if you’re struggling to make payments. They may offer hardship programs or alternative payment plans.
  • Prioritize debt repayment in your budget to avoid falling behind.
  1. Co-Signing Loans

Co-signing a loan for someone else can impact your credit score if the primary borrower misses payments or defaults.

How to Avoid:

  • Carefully consider the risks before co-signing. Ensure you can afford to make payments if the primary borrower cannot.
  • Monitor the loan account regularly to ensure payments are made on time.
  1. Settling for Minimum Payments

Paying only the minimum payment on your credit cards can lead to high interest charges and prolonged debt, negatively impacting your credit score.

How to Avoid:

  • Aim to pay your credit card balance in full each month to avoid interest charges.
  • If you can’t pay the full balance, pay as much as possible above the minimum payment.
  1. Ignoring Small Debts

Small debts, such as unpaid parking tickets or utility bills, can be sent to collections and negatively impact your credit score.

How to Avoid:

  • Pay all bills, regardless of size, on time.
  • Monitor your accounts and address any overlooked debts promptly.
  1. Applying for Too Much Credit at Once

Submitting multiple credit applications within a short period can result in several hard inquiries, which can lower your credit score.
