If all of your cards have zero
balances then you have nothing to worry about, whether you close cards or leave
them open. However, if your credit reports show balances on any other cards
then read on, as closing cards could hurt your score if you're not careful.
Credit utilization is the scoring
formula's way of assessing how much of your available credit is being used,
with lower utilization leading to a higher score.
The following "before and
after" scenarios will illustrate how impacts to utilization from closing
cards can differ substantially, depending on whether or not you carry balances
on any of your cards.
Scenario 1 (both cards have $0
balances):
Both cards A and B are open. Both have $0 balances. Combined utilization is 0%.
Both cards A and B are open. Both have $0 balances. Combined utilization is 0%.
Card A is then closed, while Card B
is left open. Both have $0 balances. Combined utilization remains at 0%.
Result: In scenario #1, despite
removing $1,000 of available credit, which is what happens when you close $0
balance cards, there is no impact to utilization from closing Card A.
Scenario 2 (one card carries a
balance):
Both cards are open. Card A has a $0 balance, while Card B carries a $500 balance. Combined utilization is then 25%.
Both cards are open. Card A has a $0 balance, while Card B carries a $500 balance. Combined utilization is then 25%.
Card A is then closed, while Card B
is left open. Combined utilization increases to 50%.
Result: In scenario #2, removing
$1,000 of available credit from the balance/limit calculations doubles the
utilization percentage from 25 to 50%, despite the same amount of debt. While a
doubling of the utilization percentage will not occur with every closed card,
and your mileage will certainly vary in these situations, the simplest lesson
to learn from this exercise is to keep cards open whenever possible, especially
if you tend to carry balances on other cards.
