About Stock Average Calculator

Stock Average Calculator is a free online suite of financial calculators built for both US and Indian stock market investors. Our mission is to provide fast, accurate, and ad-free tools that help retail investors make better-informed investment decisions.

Our Mission

We believe that powerful financial analysis tools should be accessible to everyone — not just institutional investors. By combining double-precision math engines with clean, responsive interfaces, we aim to democratize investment analytics.

Dual-Market Support

Our tools support both US dollar (USD) and Indian rupee (INR) formatting. The number formatter uses the Intl API to accurately display numbers in both Western and Indian numbering systems (e.g., $1,000,000 vs ₹10,00,000). Geolocation detection defaults to your region on first visit, but you can always toggle manually.

Our Tools

• CAGR Calculator — Compound Annual Growth Rate with year-by-year growth tables and charts.
• SIP & Lump Sum Calculator — Monthly SIP or one-time investment projections with breakdown.
• Risk-Reward & Position Sizing Calculator — Exact share quantity based on account risk and stop-loss.
• Stock Average Down Calculator — Weighted average price across multiple purchase lots.
• Capital Gains Tax Estimator — Dynamic US IRS and Indian STCG/LTCG tax calculation.
