How We Rate Mutual Funds
A transparent breakdown of the star rating system displayed on TopFund.
Data Source
Most star ratings shown on TopFund come from third-party data providers (Groww/CRISIL) and are displayed as-is, unedited. When no third-party rating is available for a fund, TopFund computes its own fallback rating using the methodology below, so every fund still shows a rating. Each fund's rating card indicates whether that fund's rating is third-party or TopFund-computed.
What Each Rating Means
Top 10% of funds in its category. Consistently above-average risk-adjusted returns over 3–5 years.
Top 22.5% of funds. Above-average returns with manageable risk. Solid choice for long-term SIPs.
Middle 35% — average performers. Acceptable but check if a higher-rated peer is available.
Below-average returns relative to category peers. Proceed with caution.
Bottom 10% of category. Consistently underperforms. Consider switching to a higher-rated fund.
TopFund's Fallback Rating Methodology
This methodology only applies to funds with no third-party rating. It is deliberately simple and uses two factors:
Trailing Return Percentile
The fund's 3-year trailing return (or 1-year, if 3-year isn't available yet) is ranked as a percentile against other funds in the exact same category and sub-category. Top-quartile standing scores highest.
Expense Ratio Adjustment
Funds with an expense ratio of 0.5% or below get a one-star bonus; funds above 1.5% get a one-star penalty. Ratio between the two is neutral.
A fund needs at least 3 peers in its category with reported returns for the fallback rating to be computed at all; otherwise no rating is shown.
Limitations to Understand
- •Past performance is not indicative of future results. A 5-star fund today may underperform tomorrow if market conditions change.
- •Ratings are backward-looking. New funds with exceptional future potential may start with 3 stars due to insufficient history.
- •Category bias: Small-cap funds may appear lower-rated during bear markets even if they are top-quality for risk-tolerant investors.
- •Use ratings as one input, not the sole decision factor. Also consider your risk profile, investment horizon, and tax situation.
