Direct Plan NAV vs Regular Plan NAV Divergence
Direct plan and regular plan of the same mutual fund scheme hold identical portfolios but have different NAVs because direct plans have a lower expense ratio (no distributor commission), causing the direct plan NAV to grow faster and diverge increasingly over time, with the gap representing the cumulative cost of distribution.
Both the direct plan and regular plan of a scheme share the same underlying portfolio — the same stocks, bonds, and proportions managed by the same fund manager. The only structural difference is the expense ratio: direct plans do not pay distributor commissions, so their TER is lower, typically by 0.5-1.0% per annum for equity schemes. This cost difference, compounded over years, creates a widening NAV gap between the two plans.
At inception (usually when direct plans were introduced in January 2013 as per SEBI regulations, or at scheme launch for newer schemes), both plans start with the same NAV (typically Rs 10). As time passes, the direct plan's NAV grows faster because the lower annual deduction means more of the gross return is retained. A scheme launched in 2013 with a 1% expense ratio difference might have seen its direct plan NAV reach Rs 85 by 2024 while the regular plan NAV reached only Rs 72 — a gap of Rs 13 representing the compounded cost of the commission.
Investors evaluating a fund's performance should always check whether returns are being quoted for the direct or regular plan. Many comparison tools default to regular plan returns (which are lower), and some advertisements historically quoted regular plan past performance, which could mislead investors comparing with direct plan benchmarks. SEBI has mandated that AMCs separately report returns for both plans.
Switching from a regular plan to the direct plan of the same scheme is technically a switch transaction — it is a taxable redemption event. For investors with large unrealised gains in regular plans, the tax impact of switching must be weighed against the long-term saving from the lower direct plan expense ratio. A rough breakeven analysis: if the tax on switching costs 10% of corpus and the annual expense ratio saving is 0.8%, the breakeven is approximately 12-13 years of future investing post-switch — suggesting that early in an investment journey, switching is almost always worthwhile, but for mature long-tenure holdings with large gains, the analysis is more nuanced.
The NAV divergence concept is also used to illustrate the power of compounding cost reduction. A 1% annual difference may appear trivial, but on a Rs 50 lakh corpus over 20 years at 12% gross return, the direct plan would generate roughly Rs 48-55 lakh more than the regular plan, purely due to the expense ratio difference.
