Developed by financial analyst MDXY1 with over a decade of experience in quantitative finance, our Share Average Calculator is a specialized tool for computing weighted average costs in multi-transaction stock portfolios. This addresses the common challenge of tracking true cost basis amid fluctuating market entries, a principle rooted in FIFO/LIFO accounting standards adapted for personal investing.

How the Share Average Calculator Works

Employing the weighted average formula—Average Price = (Σ (Quantity × Price)) / Σ Quantity—our tool aggregates transaction data for exact results. This methodology, endorsed by bodies like the CFA Institute, accounts for varying lot sizes, providing a reliable breakeven threshold for profit/loss assessments. For instance, buying 100 shares at ₹100 and 200 at ₹150 yields an average of ₹133.33, enabling precise return projections.
