NAV calculation rules for Indian mutual funds
The NAV calculation rules for Indian mutual funds are the regulatory framework prescribed by SEBI governing how Net Asset Values are computed, published and audited. The rules are codified in the SEBI (Mutual Funds) Regulations 1996 and the SEBI master circular on mutual funds, with detailed valuation methodology covering each asset class held by mutual fund schemes.
For an Indian retail investor, the NAV calculation rules are largely operational background, but they matter because they determine the reliability and consistency of the daily NAV that drives subscription and redemption pricing. A consistently and accurately computed NAV is essential for the mutual fund framework to be trustworthy at scale.
This article covers the SEBI NAV calculation framework, the per-asset-class valuation methodology, the audit and reconciliation requirements, the transparency obligations, and the recent reforms.
SEBI NAV calculation framework
Daily NAV requirement
Every open-ended mutual fund scheme must compute and publish NAV every business day. Close-ended schemes are required to publish NAV at least weekly (but in practice most publish daily). Liquid schemes have a same-day NAV cycle, while equity and most debt schemes have a T+0 to T+1 publication cycle.
Publication channels
NAV must be published on:
- AMC website: By 11:00 pm of the same business day (or next business day for schemes with overseas exposure).
- AMFI website: Consolidated industry NAV publication.
- Financial news media: Wires services and newspapers.
Standardised methodology
SEBI mandates standardised valuation methodology across all AMCs for consistency:
- All AMCs use the same closing-price methodology for listed equity (NSE/BSE closing).
- All AMCs use the same SEBI-approved valuation agencies for debt valuation.
- All AMCs follow the same SEBI methodology for unlisted equity, foreign securities, and other asset classes.
This standardisation enables direct cross-AMC NAV comparison without methodology adjustments.
Per-asset-class valuation rules
Listed Indian equity
Listed equity is valued at the closing market price on the principal stock exchange (NSE or BSE ). Where the security did not trade on the valuation day, the previous trading day’s closing price is used, subject to stale-price guidance.
Unlisted equity
Unlisted equity is valued by approved methodology that may include:
- Comparable-multiple methods using listed peers.
- Recent transaction-based valuation.
- Discounted cash flow analysis.
The unlisted equity valuation must be reviewed and approved by the trustee company periodically.
Debt instruments
Debt instruments are valued through SEBI-approved valuation agencies:
- CRISIL Valuation Agencies.
- ICRA Valuation Agencies.
- CARE Valuation Agencies.
These agencies publish daily mark-to-market valuations for the universe of corporate bonds, government securities, money-market instruments and other debt.
Money market instruments (up to 60 days)
For instruments with residual maturity up to 60 days, schemes can use the amortisation method (straight-line accrual). This simplifies valuation for very-short-tenor instruments where mark-to-market prices typically match amortised values closely.
Government securities
Indian government bonds are valued through FIMMDA published rates, with valuation-agency adjustments as applicable.
Foreign securities
Foreign holdings are valued at closing market prices on the principal foreign exchange, converted to Indian rupees at the RBI reference rate or the exchange’s published rate. The valuation typically occurs on T+0 for the foreign market close, with NAV publication on T+1 in India.
Real estate and infrastructure exposures
For schemes with REIT or InvIT exposure, the valuation uses the exchange-traded REIT/InvIT prices. Direct real-estate holdings (rare in mutual fund schemes) require independent valuation.
Liabilities
The principal liability is the daily TER accrual:
- Daily TER charge = scheme AUM × annual TER / 365.
Other accruals include:
- Audit fees (annual contract, daily pro-rata accrual).
- Custodian fees (typically basis points of AUM annually, daily pro-rata).
- Trustee fees (annual amount or AUM-based percentage, daily pro-rata).
- Specific service charges (RTA fees, fund-accountant fees, etc.).
Unit-count adjustments
NAV uses the units outstanding at the close of the business day, adjusted for:
- Subscriptions received and cleared: New units allocated at applicable NAV.
- Redemptions executed: Redeemed units removed from outstanding.
- Switches: Treated as redemption from source plus subscription to target.
The applicable-NAV rules under SEBI’s cut-off framework determine which day’s transactions count for which day’s NAV.
Audit and reconciliation
Daily reconciliation
AMCs perform daily reconciliation:
- AMC scheme accounting versus custodian holding records.
- AMC scheme accounting versus RTA unit-holder records.
- Bank account transactions to scheme cash flows.
Discrepancies must be resolved before NAV publication.
Quarterly trustee review
The trustee company reviews:
- NAV computation methodology compliance.
- Significant valuation events (e.g., unlisted equity write-downs).
- Scheme expense accruals.
- Audit findings on prior period.
Annual statutory audit
Each mutual fund scheme is subject to annual statutory audit:
- Audit by SEBI-registered statutory auditor: Verifying scheme accounts.
- NAV accuracy review: Sample testing of daily NAV computation.
- Internal control assessment: Of the AMC’s NAV computation process.
SEBI inspections
SEBI conducts periodic inspections of AMC NAV computation processes. Issues identified can result in:
- Directives for process improvement.
- Penalties for violations.
- Public disclosures of significant findings.
Recent reforms
February 2021 applicable-NAV amendment
The February 2021 amendment requiring fund realisation before cut-off (rather than just instruction receipt) affected NAV applicability rules. See applicable NAV cut-off rule .
Post-Franklin Templeton debt valuation reforms
The April 2020 Franklin Templeton episode exposed weaknesses in debt-fund valuation during stress. SEBI strengthened:
- Stricter use of valuation-agency prices rather than matrix-based valuations.
- Stress-testing requirements for debt schemes to publish liquidity-stress test results.
- Side-pocketing framework for illiquid debt instruments held by schemes.
2024 stress testing requirements
SEBI introduced mandatory stress testing for mid-cap and small-cap equity schemes in 2024, requiring AMCs to publish monthly stress-test results showing scheme behaviour under prescribed redemption scenarios.
Investor implications
Reliability
The NAV calculation rules provide structural reliability:
- Standardised methodology across AMCs ensures consistency.
- Daily reconciliation prevents accumulation of errors.
- Audit and oversight detect systemic issues.
- SEBI inspections enforce compliance.
Transparency
Investors can verify NAV through multiple channels:
- AMC website (primary source).
- AMFI consolidated industry NAV.
- Direct-plan platforms displaying NAV.
- Financial news media.
Historical NAV access
For tax-computation and performance-analysis purposes, historical NAVs are available:
- AMC websites typically publish daily historical NAVs going back several years.
- AMFI maintains consolidated historical NAV databases.
- Third-party platforms (Value Research, MoneyControl) provide historical NAV access.
