A highlight of a visit to Lake Constance is a chance to visit the wonderful Pfahlbaumuseum Unteruhldingen, the German Stilthouse Museum, an open-air museum with reconstructions of stone-and bronze-age homes.
Technically speaking, APR (annual percentage rate) is a numeric representation of your interest rate. When deciding between credit cards, APR can help you compare how expensive a transaction will be on each one.
A variable APR, however, is an interest rate that is normally tied to another rate, such as the prime rate or Treasury bill rate. If the other rate changes, it is likely your interest rate will change accordingly, whether it be up or down. A variable APR can change from day to day. For instance, if you have a credit card with a variable interest rate, look in your cardholder agreement to see to which interest rate your APR is tied.
