Generally (Ed.: Really, really generally), your credit score is based on five factors:
- Your Payment History: This is the big one, accounting for 35% of your score. Obviously lenders are going to be interested in whether you're consistent about paying back what you owe. Pay every month, on time, and you'll be in good shape.
- Credit Utilization: This is another big one, accounting for 30% of your score. This factor is made up of two parts. First, the percentage of your available credit that you're currently using; i.e. if you have $100,000 in available credit across all your cards and your monthly balances amount to $25,000, you have 25% utilization. Second, you percentage of available credit used in each individual account, i.e. a $1,000 balance of a card with a $2,000 limit is 50% utilization.
- The Length of Your Credit History: Now we're getting into the smaller factors. The average age (older is better) of your accounts makes up 15% of your score. This is a good reason to keep older cards, especially if they have no annual fee.
- Credit Mix: This is another small category, accounting for 10% of your score, that takes into account whether you have a mix of installment (e.g. mortgage) and revolving (e.g. credit card) accounts.
- New Accounts: The number of "new" (one year old or less) accounts in your credit file makes up the final 10% of your score. These are generally tracked based on when the card issuer makes a "hard pull" of your credit file to gauge your creditworthiness. Hard pulls generally stay on your credit file for 2 years, though they have a diminished weight as time goes on.
So what does all this mean? Well, I'd say it means that you shouldn't be unduly worried about the effect that a new card will have on your score. As a rule of thumb, expect that a new card application will result in a temporary (drop your score by 3-6 points.
