Introduction

Until April 2026, mutual fund investors saw one bundled number — Total Expense Ratio — that mixed together the fund manager's fee with trading costs and government taxes the fund manager doesn't control. SEBI's 2026 regulations unbundled that figure, and this calculator applies the same unbundled logic to show you what you're actually paying for skill versus what you're paying for tax and turnover.

Complete Guide: What Changed in 2026

SEBI notified the SEBI (Mutual Funds) Regulations, 2026 on 14 January 2026, effective from 1 April 2026, replacing the nearly three-decade-old 1996 framework. The centrepiece of the overhaul is a restructured expense disclosure: Total Expense Ratio is now explicitly defined as the sum of three separate components rather than one bundled cap.

Base Expense Ratio (BER) covers only what the Asset Management Company charges for managing your money — fund management, distributor commissions, and registrar/transfer agent charges. Brokerage and transaction costs cover what the fund spends buying and selling securities, now capped at reduced limits of 5 basis points for cash market trades and 1 basis point for derivatives, down from 12 and 2 basis points respectively. Statutory levies — GST, STT, CTT, stamp duty, and exchange fees — are now charged strictly on actuals, sitting outside the BER cap entirely rather than being absorbed within it.

Alongside the unbundling, SEBI reduced the maximum BER ceilings themselves. Equity schemes with AUM up to ₹500 crore saw their cap fall from 2.25% to 2.10%; debt schemes in the same bracket moved from 2.00% to 1.85%; and index funds and ETFs saw their cap reduced from 1.00% to 0.90%. For funds of funds, the BER is now capped at twice the weighted average BER of the underlying schemes they invest in.

The BER vs TER Formula

Common Mistakes to Avoid

• Comparing old TER figures directly with new BER figures. They measure different things now — BER excludes levies that old TER included, so a lower BER doesn't automatically mean a cheaper fund overall.
• Ignoring statutory levies when comparing funds. A high-churn fund can carry meaningfully higher brokerage and STT costs even with an identical BER to a low-churn peer.
• Assuming index funds have zero meaningful cost difference. Even the gap between a 0.10% and 0.30% index fund compounds into a real rupee difference over 15-20 years.
• Underestimating small percentage differences. A 0.10% cost reduction on a large, long-held corpus can mean lakhs of rupees over two decades, purely from reduced compounding drag.

Worked Example

Example — Higher-Cost Active Fund. ₹10,00,000 invested for 20 years at a 12% gross return, in a fund with BER 1.8%, brokerage 0.05%, and levies 0.15% (TER 2.00%), grows to approximately ₹66.5 lakh net of costs — versus roughly ₹96.5 lakh at the full 12% gross rate, a cost drag of around ₹30 lakh over the period.

Example — Lower-Cost Index Fund. The same ₹10,00,000 for 20 years at 12% gross, but with BER 0.30%, brokerage 0.02%, and levies 0.08% (TER 0.40%), grows to approximately ₹90.7 lakh — a cost drag of only about ₹5.8 lakh, illustrating roughly ₹24 lakh in preserved returns purely from the lower-cost structure.

Conclusion

The unbundling of BER and TER doesn't lower your actual cost by itself — that depends on the specific fund you hold — but it does let you see, for the first time in one clean breakdown, exactly which rupee pays for management skill and which pays for trading and taxes. Running your own fund's disclosed BER, brokerage, and levies through this calculator turns a fact-sheet footnote into a concrete rupee number worth comparing before you commit fresh capital.
