Considering the transaction fees involved in IMPS and NEFT, NEFT is more affordable than IMPS. This is primarily because most banks provide free NEFT services for transactions initiated online through net banking. On the other hand, if a person intends to avail of NEFT services at the nearest branch, some transaction fees might be involved.  However, the transaction fee of IMPS is generally charged based on the transaction amount while both being secured and reliable payment methods.
