Can a credit card company raise my rates for making a large payment?
No. That's pretty unlikely. Card issuers typically base your rate on your credit score. Paying down debt reduces your percent of available credit used, and improves your score until you are in the 1-20% range. That's optimum. To this issuer, you are one of a million customers, there's no emotion in this, just numbers to them. For what it's worth, if a card issuer raises your rate, you are permitted to "not accept" the rate, stop using the card for new charges, and pay at the current rate. Of course this doesn't apply to zero interest deals, only to increases to your regular rate.
