how often do you have to make purchases w/ your credit card for it to stay active?

Question

?

Answer 1

Depends on the company, but i believe you have to use it every 6 months to have a positive impact on your FICO. It doesnt factor accounts with no activity for 6 months.

Answer 2

One a year is plenty but I have used some that I let lay for up to about 3 years. It was funny because I didn't use it for 3 years then I bought 390,000 yen in travelers checks online from another bank. They called to confirm since it was an unusual transaction.
