Frequently asked questions
Are these stock calculators free and client-side?
Yes, 100%. Every calculation runs locally in your browser using pure JavaScript. Your portfolio holdings, trades, and financial inputs are never stored, logged, or sent across the network.
How does the Stock Average Price Calculator work?
It computes the volume-weighted average price across multiple buy lots. If you buy 50 shares at $100 and 50 shares at $80, your weighted average cost basis is $90 per share.
What is the difference between DCF and Reverse DCF?
A standard DCF calculator estimates fair intrinsic value per share based on your projected cash flows and discount rate. A Reverse DCF works backward from the current market price to show what annual growth rate the market is currently pricing in.
Why should I use a Position Size Calculator?
Proper risk management prevents portfolio blowups. A position size calculator limits the maximum dollar amount risked on any single trade (e.g., 1% or 2% of total capital) based on your stop-loss distance.
What is XIRR in stock investing?
XIRR (Extended Internal Rate of Return) calculates your annualized returns when cash inflows and outflows occur at irregular dates, which is common with dividend reinvestments, SIPs, and periodic equity buys.
