Let’s say you started a new SIP on March 3 and have selected 1st of every month as the SIP deduction date.
There needs to be a minimum 30 days difference between the SIP start date and the first installment, so your next installment will not be deducted on 1st April, but on 1st May.
For all subsequent months, the money will be deducted regularly on the 1st of every month.
Please note, in case of a bank holiday, SIP will be deducted on the next working day.
