How to use it: Add the price and share count for each purchase—up to five entries. It combines them and shows what you paid on average for each share. Example: 10 shares at $100 cost $1,000 and 5 at $80 cost $400; together, 15 shares cost $1,400, so the average is $93.33 per share.

Common questions

Does this calculator use live market data?

No. Every value comes from the assumptions you enter. A ticker symbol, when shown, is only a label.

Can I make a trade based on this result?

The result is an educational illustration, not a recommendation or a complete analysis. Verify current facts, account rules, costs and risks independently.

Why might the actual result be different?

Real outcomes can be affected by execution price, spread, slippage, fees, taxes, liquidity, volatility, financing costs, corporate actions and changing market conditions.
