Duke - I heard it was better to put a small amount (like 100-200 dollars) on a credit card, and make the minimum payments every month. somehow that was supposed to build your credit faster than paying the whole amount (and not getting charged any interest). Is this true or is it better, from a credit building standpoint, to pay the whole sum off every month.
As far as I know, this is incorrect. It will do nothing good for your credit score that I know of.
Credit card companies make money on surcharges to vendors as well as on interest. In fact, they prefer that rather than interest charges, because they get their money back faster and can recirculate it faster.
If they make 1% surcharge and 10% interest per year on my $1000 balance, and it takes me a year to pay back that $1000, they've made $110 in that year.
But if they make 1% surcharge and 10% interest on that $1000 and I pay it off every month, they can lend me the same $1000 for 12 purchases instead of 1 and make $120, plus they get their money back in their own hands much more quickly to boot.
Profits are not just about absolute percentage numbers, but also about how quickly the money turns around. It's much better to make a little profit but cycle through many fast transactions than it is to make a large profit on a very small number of transactions that take a long time to complete.
In general, your credit score is going to be based on A) timely payment, and B) low debt-to-income ratio.
