Understand what a mutual fund actually earns you, net of what it quietly costs.
A mutual fund sells you "returns", but the number that matters is the return you keep after cost — and cost is a silent daily drag on NAV, not a bill you ever see. It maps what's underneath: how a fund is priced, what it charges, what it actually earns net of that charge, the product shelf SEBI defines, the SIP flows that build its AUM, and the benchmark-and-risk scorecard that judges it. Mapped from cause to effect.

Start Here
A four-stop tour of the whole map — the price a fund is struck at, the one number that actually matters (return net of cost), the monthly habit that built the industry, and how you judge a fund off its factsheet. Fifteen minutes before you pick a deeper path.

The Fund Mechanics
What a fund actually is and how its price is struck. NAV is the atom everything downstream is priced in, so this is where to start: how the per-unit price is set, why it moves every day, the pool it all scales on, and the timing rule that decides which day's price you get.

The Cost Stack
What you pay, and where it's hidden. Cost is the one variable you control and the surest predictor of what you keep. From the all-in expense ratio down to what's inside it, the sliding cap that limits it, the plan choice that halves it, and the penalty for leaving early.

The Return Engine
What you earn, net of cost — the spine of the whole map. From the manager's raw gross return, minus the fee, down to the return that lands in your NAV and the honest ways to measure it: CAGR for a lumpsum, XIRR for a SIP, rolling returns to kill the cherry-picked date, and total return for a fair yardstick.

Fund Categories
SEBI's product shelf. Since 2017 every fund sits in a defined box, so 'which fund' is really 'which box.' From the rulebook that fixed the boxes, through the equity, debt and hybrid shelves, to the passive alternative — index funds and ETFs — and the short, safe end where you park cash.

Investor Flows & Behaviour
How money comes in and stays. The SIP is India's structural innovation and the closest thing funds have to a bank's sticky CASA book. From the monthly habit and the averaging maths behind it, through the lumpsum-versus-SIP decision, up to the industry view: the sticky SIP book, net flows, and how wide the habit has spread.

How the Fund Is Judged
Read any fund's factsheet without being fooled. Return alone lies; the verdict is return net of cost, measured against a fair benchmark, adjusted for the risk taken. The factsheet scan first, then the one relationship the data keeps proving, then the cost, the net return, the benchmark and alpha, the risk numbers, and the quality test for passive funds.
