Because of several factors and competition, IRCA lead Auditor course fees in India have reduced drastically. The following are some of the reasons.

Several new training bodies have been accredited by IRCA which in turn has reduced the charges due to increased competition.
The Indian Rupee has depreciated significantly against major international currencies in the past few years, making training courses more affordable for international candidates.
The increased demand for Indian auditors in the Middle East and other countries has led to a reduction in the lead auditor course fees in India.
In addition, some organizations are offering flexible payment options such as installment plans which makes it easier for candidates to pay for the training.
