How Mutual Fund Returns Work
Mutual fund returns are driven by the change in NAV (Net Asset Value) over your holding period. When the underlying securities (stocks, bonds, etc.) in the fund's portfolio appreciate, the NAV rises, and your investment grows. Returns can be measured as absolute return (total gain) or CAGR (annualized growth rate).
NAV Explained
NAV represents the per-unit value of a mutual fund scheme. It is calculated daily by the fund house as: (Market Value of All Securities + Cash - Liabilities) / Total Outstanding Units. When you invest ₹10,000 in a fund with NAV ₹50, you receive 200 units. If NAV rises to ₹65, your investment is worth ₹13,000 — a 30% absolute return.
The Impact of Expense Ratio Over Time
The expense ratio is an annual charge covering fund management fees, administrative costs, and distribution commissions. It is deducted daily from the fund's assets, reducing the NAV. While 1%–2% may seem small, the compounding effect over long periods is dramatic:
- ₹10 lakh invested for 20 years at 12% gross return: With 0.5% expense ratio, you get ₹89.5 lakh. With 2.0% expense ratio, you get ₹56.0 lakh — a ₹33.5 lakh difference.
- Each 0.5% reduction in expense ratio adds approximately 8%–10% to your final corpus over 20 years.
Direct vs Regular Plan Comparison
Every mutual fund scheme offers two variants: Direct and Regular. The only difference is the expense ratio — Direct plans have lower expense ratios because they don't include distributor commissions.
A typical large-cap equity fund might have a 0.5% expense ratio for the Direct plan and 1.5% for the Regular plan. Over 15 years on a ₹1 lakh investment, this 1% annual difference can result in the Direct plan delivering 15%–20% more corpus. For new investments, Direct plans through platforms like Kuvera, Groww, or the AMC's own website are almost always the better choice.
Frequently Asked Questions
What is NAV and how is it calculated?
NAV (Net Asset Value) is the per-unit market value of a mutual fund. It is calculated as (Total Assets - Total Liabilities) / Number of Outstanding Units. NAV is updated at the end of each business day after market close. When you buy or redeem mutual fund units, the transaction happens at the applicable NAV.
How does expense ratio affect my mutual fund returns?
The expense ratio is an annual fee charged by the fund house, deducted daily from the fund's NAV. A 1.5% expense ratio on a ₹10 lakh investment costs you ₹15,000 per year. Over 20 years at 12% gross return, a 1.5% expense ratio reduces your corpus from ₹96.5 lakh to ₹67.3 lakh — a difference of nearly ₹29 lakh. This is why lower expense ratios matter enormously over long holding periods.
What is the difference between CAGR and absolute return?
Absolute return is the total percentage gain or loss on your investment regardless of time — e.g., investing ₹1 lakh that becomes ₹1.5 lakh is a 50% absolute return. CAGR (Compound Annual Growth Rate) annualizes this return to show the equivalent yearly growth rate. If that 50% return took 3 years, the CAGR would be 14.47%. CAGR is more useful for comparing investments held for different durations.
What is the difference between direct and regular mutual fund plans?
Direct plans are purchased directly from the fund house (via their website or apps like Kuvera, Groww). Regular plans are bought through distributors/agents who receive a commission (0.5%–1.5% annually) from the fund house. This commission is built into the expense ratio, making regular plans more expensive. Over 20 years, the difference can amount to 15%–30% of your total corpus.
When should I exit a mutual fund?
Exit when your financial goal is approaching (shift to safer instruments 1–2 years before the target date), when the fund consistently underperforms its benchmark and peers for 4+ quarters, or when your asset allocation drifts significantly from your plan. Avoid exiting during short-term market corrections — equity funds need 5+ years to deliver optimal returns. Check exit load (typically 1% if redeemed within 1 year) before selling.
