Definition: A credit card introductory period is the amount of time a low-interest rate introductory offer lasts. By law, the introductory period must be a minimum of six months. After the introductory period has ended, the interest rate will increase to the regular APR which is typically higher than the introductory rate.
If you sign up for an introductory interest rate offer, it's important that you know how long the introductory period lasts and what the interest rate will be when it ends.
