Why the same fund shows a different expense ratio on every platform

Three platforms, three numbers, none of them wrong. They're measuring different layers of the same stack.

Look up the same mutual fund's expense ratio on three different platforms and you can easily get three different numbers. None of them is necessarily wrong. They're measuring slightly different things, and the fund industry has never settled on a single convention for which one to display.

This piece explains what the layers are, which one StockLearn shows, and why we say so on every fund page rather than presenting a single figure as definitive.

The expense ratio is a stack, not a number

A fund's total running cost is built from several components. The largest is the investment management and advisory fee. On top of that sit registrar and transfer agent charges, custodian fees, audit fees, and marketing and distribution expenses.

Indian regulation then permits certain additional charges beyond the base slab — including an incentive for inflows from smaller cities, and specified additional expenses. Goods and services tax applies to the management fee.

Depending on which of those layers you include, you get a different "expense ratio" for the same fund on the same day.

Base TER vs total TER

The two figures most commonly quoted are:

• Base TER — the expense ratio under the regulatory slab structure, before the permitted add-ons and GST.
• Total TER — the all-in figure including those additional components.

Total TER is the higher number, and it is closer to what actually comes out of your returns. Base TER is what appears in a lot of published data, including the industry-body files that most free screeners are built on.

Direct and regular are a separate axis

Cutting across all of the above is the plan distinction. A regular plan pays distribution commission out of the fund; a direct plan does not. The direct plan's expense ratio is therefore lower — often materially so for equity funds.

This is a different question from base versus total. Each plan has both a base and a total TER. Our pages cover direct plans only, so a regular-plan investor comparing against our figures will see a gap that has nothing to do with the base/total distinction.

Why the difference is worth caring about

Expense ratios are quoted as small annual percentages, which makes them feel negligible. Compounded over a long holding period they are not. Our separate guide on expense drag works through the arithmetic on a realistic holding period, and the figure surprises most people.

The base-versus-total gap is smaller than the direct-versus-regular gap, but it runs in the same direction: the number you see quoted is usually the flattering one, and the number that actually comes out of your returns is usually higher.

The ratio is deducted daily, not annually

One more point that causes confusion. The expense ratio is an annual rate, but it is accrued and deducted from the fund's net asset value every business day, in proportion.

You will never see an expense charge on a statement. It is already inside the NAV — the published NAV is after expenses. So a fund's stated returns are net of its expense ratio, and adding the two together to estimate a gross return is not how the arithmetic works.

Vintage matters too

Expense ratios change. Funds revise them, and the regulatory slabs depend on fund size, so a fund growing across a slab boundary sees its permitted maximum fall.

The figure on a fund page therefore has a date attached, and it isn't the same date as the NAV. Our NAV updates daily; the expense ratio updates on a slower cycle, and fund size slower still. A page can correctly show yesterday's NAV alongside an expense ratio from an earlier vintage — each field is current for the frequency at which it's published.

This guide explains how mutual fund expense ratios are constructed and reported. It is educational and is not investment advice or a recommendation of any fund. Scheme documents from the AMC are the authoritative source for a fund's charges.
