| Fund Type | Short Term | Long Term | STCG Rate | LTCG Rate |

| Equity | < 1 year | โฅ 1 year | 20% | 12.5% (>โน1.25L) |

ฮฃ(Return ร Weight) where weight = fund value / total portfolio value. Calculated for 1Y, 3Y, and 5Y.
FV = P ร ((1 + r)^n - 1) / r ร (1 + r) with optional annual step-up applied each year. Projected in parallel using 6M avg SIP, 12M avg SIP, and custom SIP.
All series indexed to 100 at the selected period start date. Monthly data points are sampled from daily NAV history. Funds without a full period history use their earliest available NAV as the base and are labelled "since MMM 'YY". CAGR formula used for annualized return in best/worst cards: ((1 + totalReturn/100)^(1/years) - 1) ร 100.
Generates a file signature from content hash, file size, and binary fingerprint. Warns if the same file is uploaded again to prevent duplicate data entry.
Processes all transactions chronologically against NAV history to calculate daily unit count and portfolio value for each fund. Powers fund-level and portfolio-level growth charts.
Same fund can have multiple folios (e.g. regular + direct plan). Each folio has its own FIFO queue tracked independently, then aggregated into a single fund card.
Fetched from Groww API: Alpha, Beta, Sharpe, Sortino, 1Y/3Y/5Y returns, category averages, benchmark comparison, holdings, AUM, expense ratio, rating. NAV history from MFAPI.
