MAB

MAB stands for Monthly Average Balance.

It is the average amount a customer must maintain in a savings or current account over a calendar month, calculated by summing the end-of-day closing balances and dividing by the number of days. Most Indian banks set an MAB of ₹3,000 to ₹10,000 for savings accounts and ₹5,000 to ₹25,000 for current accounts. Falling below the MAB attracts a non-maintenance penalty of ₹100 to ₹600 per month.
