No, the higher mandate limit does not mean extra money will be deducted.
It’s only a ceiling set for safety.
Each month, only your actual EMI — exactly as per your loan schedule — will be debited.
You will never be charged more than your agreed EMI.
Example:
If your EMI is ₹2,000, you will only be debited ₹2,000 on the 1st of every month until your loan tenure ends.
The higher limit is simply a buffer to make sure your EMI gets processed smoothly.
