The Return Engine

Net Return (after TER)

What actually lands in your NAV once cost is stripped out — the honest number, and the one the whole map points at.

Why you care

This is the number that matters. Gross return is the manager's; net return after TER is yours — what's left in your NAV once the fund has quietly taken its cost. If you track one figure in this whole map, track this one. It's the funds version of what NIM is to a bank: the verdict on the core job.

Run the numbers

Gross 12%, TER 1.75%, so net return is 10.25% (illustrative). On ₹10 lakh over 20 years that 1.75% gap is not small change — it's the difference between roughly ₹70 lakh (net) and ₹96 lakh (if cost were zero). The honest number is always the one measured after cost, never before.

Where this goes

Net return is where the spine resolves. It shows up as the NAV growth you keep, it's the base your real XIRR is built on, and measured against the benchmark its excess is alpha. Cost is the one lever that reliably moves it — which is the whole cost vs performance story.

Why you care

Net return after TER is the return that actually reaches you: the fund's gross return minus its total expense ratio, reflected in the NAV you own. Gross is what the portfolio earned; net is what you kept after the fund was paid. This is the honest number, and it's the one the entire map is built to point at.

It's the spine node for the same reason NIM is the spine of a bank or the combined ratio is the spine of a general insurer. It's the one-number verdict on the core activity, told from the point of view of the person who put up the money. A bank's whole apparatus resolves into "what did we earn on the spread." A fund's whole apparatus — the manager, the costs, the plan you chose, the AUM — resolves into "what did the investor keep, net of cost." Every other node either feeds this number (the cost stack drags it down, the flows build the AUM it's earned on), or judges it. The benchmark and risk scorecard ask whether it was good enough for the fee. Marketing will always prefer to quote gross. The discipline this map is trying to build is the reflex of asking, every time you see a return, "is that before or after cost?"

Run the numbers

Take the fund from the gross-return example (illustrative):

Line Value
Gross return (portfolio) 12.00%
Less: TER 1.75%
Net return after TER 10.25%

Now let the difference run. On a ₹10 lakh lumpsum held 20 years:

  • At the net 10.25%: about ₹70.4 lakh.
  • At the gross 12% (as if cost were zero): about ₹96.5 lakh.

The fee didn't cost you 1.75% once. Over two decades it cost roughly ₹26 lakh of final corpus, because it was skimmed off the compounding base every year. This is why "net of cost" isn't an accountant's footnote; it's the difference between two very different retirements. The number you plan your life around has to be the net one.

Where this goes

Net return is where the spine of this vertical resolves, and three things flow out of it. It's the NAV growth the investor actually keeps. Measured against the benchmark, its excess (or shortfall) is the fund's alpha — the test of whether active management earned its fee. And it's the base from which the investor's real, timing-aware XIRR is computed once you account for when each rupee went in. Underneath all of it sits the single most reliable finding in fund data: the relationship between cost and this net number is negative and stubborn, which is why the cheap fund keeps winning.
