Risk disclaimer
A negative book cost is an accounting view; the remaining position still carries risk.
vs the average-cost method?
Average cost keeps the original basis for what remains.
Recovery subtracts proceeds from total cost — selling higher lowers your effective remaining cost, possibly below zero (a mental “house money” framing, not a risk statement).
How to use
- Enter the average cost and total quantity.
- Enter the sell quantity and price.
- Click Calculate for proceeds, realized P&L and the effective remaining cost.
Formula
- Total cost = average × total qty
- Effective remaining = total cost − proceeds
- Per unit = effective remaining ÷ remaining qty
Example
Avg 100, total 2; sell 1 @160 → proceeds 160, cost 200 → effective cost of the remaining 1 = 40.
When proceeds exceed total cost the effective cost goes negative — the stake is “returned”.
FAQ
Which method is correct?
Both are accounting conventions: average cost suits tax records; recovery is intuitive. Stay consistent with your own records.
