A 0% APR is essentially a credit card offered by credit card companies to their consumers with an 'annual percentage rate' (APR) of zero percent. However, this rate does not exist forever, and after a period that ranges between three to twelve months, credit card companies begin charging higher rates of interest. Therefore, the major factors to be considered are the duration of the no-interest period, and what would be the APR rate after the offer ends.
