Beginner guide: what this tool does
  • Average cost per share: your blended entry price after combining all fills and fees.
  • Position value: the raw dollar value of the shares you bought before fees.
  • Breakeven price: the share price you need to recover your total cost, ignoring taxes and exit fees.
  • DCA warning: a lower average cost does not automatically mean the position is safer or the thesis improved.
  • Local storage: saved tickers stay on this browser and device until you clear them or import a different backup.
Educational use only. This calculator is a planning aid only. It does not account for taxes, broker-specific fee structures, slippage, or currency conversion. Always verify fills and costs with your actual brokerage records.
