Let’s first understand what this introductory period is before I answer your question. Every time a user transfers balance from one credit card to another, the bank offers the card holder a grace period or buffer period to clear their outstanding amount at low or zero interest rates.

A user can make the most of the interest—free introductory buffer period when transferring credit card balances for a stipulated time, as stated by the bank. Usually the interest-free introductory period ranges from 3-6 months.
