Built With Care
“Understanding your true 'average cost' is critical for trading psychology. Many beginners only track their buy price, ignoring exchange fees (0.1% - 1.5%), which raises their actual break-even point. This tool factors in those hidden costs, ensuring you don't exit a trade prematurely thinking you are in profit when you are actually just covering fees.”

- Fees are included in the cost basis calculation, but the tool does not model commissions, spreads, or slippage that may occur during actual trades.
- Rounding to two decimal places means the final average cost may differ by a fraction of a cent compared to a spreadsheet using full precision.
- Current price is entered manually. The tool does not fetch live market data, so P/L figures depend on the accuracy of the value you provide.
- This tool is for informational purposes only and should not be used as the sole basis for investment decisions.
- 1Include every purchase — quantity and buy price for each order, including fees — so the average is not skewed.
- 2Enter today's market price manually to get a current profit or loss reading.
- 3Cross-check the break-even price against your broker's cost-basis records.
