People talk about a fund’s return as though it appears from nowhere. It does not. Every rupee of it arrives through one of three doors, and knowing which door tells you a surprising amount about what a fund is and how it will behave.
The three sources of return
1. Capital appreciation. The securities the fund holds go up in price. A scheme that bought a share at ₹400 and sees it at ₹520 is carrying a ₹120 gain per share, and the NAV reflects it every day — before anything is sold. This is unrealised, and it is where most equity fund return comes from.
2. Income. Dividends from the shares it owns, and interest (coupons) from the bonds it owns. This flows in continuously and lifts the NAV as it accrues. For a debt fund it is the dominant source; for an equity fund it is a modest supplement.
3. Realised gains. When the manager actually sells a holding at a profit. Note this is not a new source of return — the gain was already in the NAV as appreciation. Selling merely converts it. What selling genuinely does is trigger costs, which is why portfolio turnover matters.
All three land in the same place: the NAV. Which is why your return is the change in NAV, full stop, and why hunting for “dividend-paying funds” misunderstands the plumbing entirely.
What flows out before you see it
Against those three inflows sit the deductions, taken from the scheme’s assets daily, before the NAV is published:
- The expense ratio — management fee, admin, and distributor trail if you hold a Regular plan.
- Transaction costs — brokerage and statutory levies on the fund’s own trades.
You never see a bill because there isn’t one. This is exactly why cost discipline matters so much: an invisible charge is one nobody negotiates. The full picture is in what a fund really costs.
Two things this explains
Why a high NAV is not expensive. The NAV is total assets minus liabilities, divided by units. It goes up because the holdings went up, and it has no relationship to whether the fund is cheap. A fund at ₹800 and one at ₹15 both return 10% if their holdings rise 10%.
Why an IDCW payout is not extra return. The scheme does not earn a distribution. It hands you money that was already inside your NAV, and the NAV drops by exactly that amount. Nothing was created — and now it is taxed at your slab rate.
How your money differs from the fund’s money
The fund’s return and your return are two different numbers, and the gap is usually your own timing.
A fund that returned 14% CAGR over five years describes a rupee present for all five years. If you invested through a SIP, most of your money has been there for far less, so your XIRR will differ — sometimes materially. Neither number is wrong; they answer different questions, which is the subject of absolute, CAGR and XIRR.
Pitfalls to avoid
- Chasing “high dividend” funds for income. You are choosing a worse tax treatment for money that was yours already. A SWP does the same job better.
- Assuming a fund “books profits” for your benefit. Selling a winner realises a gain inside the scheme and creates costs. It is a portfolio decision, not a gift to unitholders.
- Reading NAV like a share price. A falling NAV is not a discount and a rising one is not expensive. Only the percentage change is information.
- Ignoring cost because returns look fine. Cost is subtracted every year, in good years and bad, and it compounds against you.
Key takeaway
A mutual fund makes money three ways — the holdings appreciate, they pay income, and gains are occasionally realised — and every rupee of it shows up as a change in NAV, net of costs already deducted. If you internalise only one thing: your return is the percentage change in NAV over your holding period, and everything else, including payouts, is bookkeeping.

Can you lose money in mutual funds? Understanding market risk
Yes — but temporary, permanent and self-inflicted losses are three different things, and the largest source of realised loss is behavioural rather than market.
