What is AUM?
Every rupee an investor has put into a scheme, plus its accumulated gains, minus any redemptions, marked to today’s NAV - add that up across every unit-holder and you get the fund’s AUM. AMCs disclose it monthly per SEBI’s mandated portfolio disclosures.
AUM = Total Units Outstanding × Latest NAV per Unit
Neither higher nor lower is inherently better - a very small fund can have a shorter track record and thinner liquidity, while a very large fund in a narrow category (small/mid cap) can start struggling to enter or exit positions without moving the price.

Reading the spread
Across these 6 funds, AUM runs from 2,215 (DSP Value) to 1,45,673 (Parag Parikh Flexi Cap), a gap of 1,43,457. The middle value is 37,718, with 3 of 6 above it. The highest reading is 65.8 times the lowest, so the choice of fund changes this number a lot. Neither end is better or worse in itself; the number describes how a fund behaves, and what matters is whether that matches what you want.
How to use it in practice
AUM is the total money a fund manages. Use it as a context check. Very small funds may be costly to run or risk closure; very large ones can find it hard to deploy money in smaller, less liquid stocks without moving prices. AUM also tells you how many investors have chosen the fund, though not whether they were right to. Read it with net flows to see whether money is arriving or leaving.
Common mistakes
A bigger AUM is not a mark of quality; it often reflects past performance and marketing. AUM also rises and falls with markets, so a jump may be price gains rather than new money. Do not choose a fund by size alone, and do not assume that a small fund is risky or a large fund is safe.
Frequently asked questions
Does a larger AUM mean a better fund?
No. Size can reflect past success or marketing. A very large fund may find it harder to invest in smaller stocks, and a very small one may be expensive to run.
Why does AUM change from month to month?
Two reasons: net flows, meaning investors adding or withdrawing money, and market movements, which raise or lower the value of what the fund holds.
What is the difference between AUM and AAUM?
AUM is the value on a given day, while AAUM is the average over a period, usually a month or quarter, and is smoother for comparison.
WHAT THIS MEANS FOR YOU Compare AUM within the same category, not across categories - a ₹50,000 Cr large cap fund and a ₹500 Cr small cap fund can both be perfectly reasonably sized for what they invest in, since small/mid cap categories simply have a smaller total investable universe.
