What is Mutual Fund Overlap and Why Does It Matter?
Mutual fund overlap occurs when two or more funds in your portfolio hold the same stocks. While some overlap is normal (especially in large-cap funds), high overlap can lead to over-concentration and 'diworsification' — where you think you are diversified but are actually holding the same underlying assets. This calculator helps you uncover that hidden risk. Smart diversification is crucial for long-term wealth building. Use our retirement corpus calculator to understand how your diversified portfolio should grow to meet your financial goals.
How Our Mutual Fund Overlap Calculator Works
Our tool compares the holdings of the funds you select and calculates the weighted overlap. This metric tells you what percentage of your portfolio is duplicated between two funds, based on the smaller weight for each common stock.

Example: If Fund A holds 5% in ICICI Bank and Fund B holds 6%, the overlap contribution from that stock is 5% (the minimum of the two). We sum this for all common shares to get the total weighted overlap.
Live Example: ICICI Pru Bluechip vs HDFC Top 100

Here is a pre-rendered example showing a typical comparison. The funds have a weighted overlap of <strong>27.02%</strong>.

How to Interpret Your Overlap Score
  • Low (0-15%): Good diversification. The funds have distinct strategies.
  • Moderate (15-30%): Common for funds in the same category (e.g., large-cap). Review to ensure you are comfortable with the shared exposure.
  • High (30-50%): Significant overlap. You may be paying two sets of fees for the same stocks. Consider consolidating.
  • Very High (>50%): The funds are practically clones. Replacing one to improve diversification is highly recommended.
What to Do If You Have High Overlap
If you find a high overlap, don't panic. Consider replacing one of the funds with another that has a different strategy or market-cap focus. For example, if two large-cap funds overlap, you might switch one to a mid-cap or a sector-specific fund to achieve true diversification. Our mutual fund screener can help you find funds with different strategies. Also explore FD vs PPF options and PPF for more conservative allocations. Use our tax regime calculator to understand the tax implications of any fund switches, and our loan optimizer to manage any debt before increasing investments.

Data & Methodology

Data Sources: Our holdings data is sourced from publicly available scheme documents and updated periodically. While we strive for accuracy, we cannot guarantee it. Always verify with official AMC factsheets. Last Updated: Aug 2025.

Matching Logic: Holdings are matched first by their stock ticker (e.g., 'RELIANCE'). If a ticker is not available, we use a normalized company name (e.g., 'reliance industries' after removing 'Ltd', 'Inc', etc.). Non-equity holdings like 'Cash', 'Tri-party repo', or 'Net Receivables' are excluded from the calculation based on a regex match for common terms.

Worked Example (Weighted Overlap):

Weighted Overlap = Σ min(weight in Fund A, weight in Fund B) for all common stocks.
