Purchase average and remaining FIFO cost are different

Before any sales, weighted average cost is total purchase cost divided by total units. The sample buys of 0.1 units at $45,000 and 0.15 at $40,000 cost $10,500 for 0.25 units: an average of $42,000. These are hypothetical prices.

When units are sold, FIFO removes the earliest acquired lots. Selling 0.1 units at $50,000 from that example realizes $500 before fees. The remaining 0.15 units have a $6,000 basis and a $40,000 average. At a $42,000 current price their unrealized gain is $300. Combined profit is $800; the remaining average alone does not describe total trade history.

Enter the sequence you actually traded

1. Enter buys and sells for one asset with USD unit prices and positive quantities.
2. Use acquisition and disposal dates. Rows sort by date; same-day trades follow the displayed order.
3. Remove incomplete rows. Overselling or selling before acquisition produces an error instead of silently dropping part of the trade.
4. Enter the current price yourself. There is no exchange connection or automatic valuation update.

Cost allocation is not a tax filing

This model excludes fees, wallet transfers, rewards, forks, currency conversion and tax-specific unit identification. The IRS digital-assets guidance describes U.S. records needed for dates, quantities, values and basis. It does not make this simplified FIFO calculation valid for every taxpayer or jurisdiction.

A lower average cost can accompany a larger total loss after buying more of a falling asset. DCA purchases do not always lower the average. Use the tool to inspect allocation, not as an instruction to add to a losing position.
