What is AUM (Assets Under Management)?
AUM is the total market value of all investments managed by a fund house or asset manager — a measure of scale and investor trust.
Formula
AUM = Sum of (NAV × Units Outstanding) for all schemes
How to Interpret
Larger AUM indicates more investor trust but may also reduce flexibility for active managers. Very large AUM can make it harder to generate alpha.
Typical Ranges
India's mutual fund industry AUM crossed ₹60 lakh crore in 2025.
