IN PLAIN ENGLISH
What you actually paid for a holding, fees included.
WHERE YOU MEET IT
Holding Cost for each holding and Total Cost for the portfolio, worked out with average cost. Fees count if you include them in the cost you record.
WATCH OUT FOR
Buying in stages moves it — the average is what matters, not your first purchase.
FULL DEFINITION
The remaining cost basis for a single holding, in your portfolio currency.
EXAMPLE
Bought 100 shares for £1,000, sold 40. Holding Cost = £1,000 − (40 × £10) = £600.
HOW IT'S CALCULATED
Holding Cost = total buy cost − (shares sold × average cost per share), where average cost per share = total buy cost ÷ total shares bought. Each buy's cost is entered in the stock's own trading currency and converted into your portfolio currency at the exchange rate on its purchase date, so later FX moves do not change what it cost; a buy whose purchase-date rate was unavailable is converted at today's rate until the holding is next saved.
