Use the same display currency for every price and flat fee. Percentage fees are applied separately to the buy and sale values.

Three-letter code only. This labels your inputs; it does not convert them.

Result

Your cost, proceeds, fees, profit or loss, ROI and break-even price will appear here.

Method: Net P/L = net sale proceeds − total acquisition cost. ROI = net P/L ÷ total acquisition cost. Percentage sell fees are recalculated at each entered scenario price.

Compare your own sell-price scenarios

These are not forecasts or targets. Enter up to three prices you want to inspect; every row uses the same fee and ROI engine as the main result.

Add one or more optional scenario prices to compare them.

Formula and assumptions

Total cost = buy price × quantity + buy fee
Net proceeds = sell price × quantity − sell fee
Net P/L = net proceeds − total cost
ROI = net P/L ÷ total cost

A percentage fee is calculated from that side of the trade. A flat fee is entered in the same display currency. Break-even is the sell price where net proceeds exactly equal total acquisition cost.
