Paying for things on credit and immediately paying them off: any help for credit rating?
The biggest risk is Credit Utilization rate.  If you have a total of $10,000 in revolving credit (ie: credit card line) and you ever have more than 50% (or 33% to be conservative) on the card at any time then your credit score will be negatively impacted. This will be a negative impact even if you charge it on day one and pay it off in full on day 2.  Doesn't make much sense but credit companies are playing the averages:  on average they find that people who get close to maxing their credit limit are in some sort of financial trouble. You're better off to make small purchases each month, under $100, and pay them off right away.  That will build a better credit history - and score.
