Not so fast. A credit card with a high limit is a good safeguard against a cash emergency. As happened to me a couple of years ago, when a sudden death had the family scrambling to get to the funeral. Six round-trip airline flights is a chunk of change, and we had to book them in 2 days.
But you won't get a high limit if the computers think you're a poor customer, an that's what their idiot programs will think if you always pay off.
A better strategy, in my opinion (as informed by one of the guys who wrote the idiot program in question), is to charge something big about once every couple of years, and take 2 to 3 months to pay it off. Yes, it costs you a little interest (about 2%), but to the computer you now smell like a rose.
I agree with that.
. . .an that's what their idiot programs will think if you always pay off.
But not with that. I always, ALWAYS pay off my credit cards and they have never lowered my available credit.
Bottom line is that if more people ran there affairs like those who have posted on this thread . . there wouldn't be any credit cards. That might be a good thing.
