While the Fair Isaac developers will not reveal the exact formula used in this software,
they have revealed how each of these factors is weighted and how you might improve
your score.
This accounts for about 35% of total score. Your payment history on credit cards,
retail accounts at stores, instalment loans and mortgages are all recorded. Specifically,
how on-time or late your payments were, how much was owed, how many late payments
and how recently they occurred are all measured.
These account for about 30% of your total score. While owing a lot of money on many
accounts might indicate that you are overextended, your score will not necessarily
be harmed by large outstanding amounts. What is more important is how many accounts
have balances and how much of the total credit line is being used on credit cards
and other "revolving credit" accounts. The short-term and volatile use of revolving
credit may indicate a lack of financial discipline.
Accounts for about 15% of total score. So if you are trying to borrow for the first
time and are trying to establish a credit record, you have few options to improve
your score here, since how long your credit accounts have been established is what
actually counts.
New credit is about 10% of the total score. Here, they look at how many new accounts
you have established, how long it has been since you opened a new account and how
many recent requests for your credit have been made by credit reporting agencies.
Until recently, your score would have gone down if you made a number of applications
for credit cards or mortgages within a short period of time - even if all you were
doing was shopping around for the best deal. Now, they lump together inquiries made
within a short period of time as one inquiry. So, if you're shopping around, make
your inquiries all within a few days if you can.
This used makes up the remaining 10% of your score. Here they are simply looking
at long-term credit like home bonds, medium-term credit like car and furniture finance
and short-term credit like department store and bank credit cards.
