Calculate trading profit and your average price after an additional purchase.

Return

Currency

Enter the buy and sell prices plus the quantity held or investment amount. The fee applies to both buy and sell.

Tax estimate

Tax residence

Tax year

Asset type

Transaction location

Disposal type

Business, corporate, major holder, unlisted, derivatives or rewards

Acquisition lots

For shares, domestic/foreign refers to issuer, listing market and income source relative to residence. For crypto it describes the provider; exchange-server location does not determine tax.

Enter remaining lots of one asset. FIFO uses oldest lots first. For Japan enter a verified average-cost pool (annual or elected moving average). Adjust for prior sales, wash sales, repurchase restrictions and adjusted basis before confirming.

Use each transaction date’s FX, not current rates. Checked included fees are not counted twice. Annual income below is in residence currency. For Spanish crypto swaps, enter the fee (0 if none). When included is checked, disposal amount is the received asset’s market value minus the fee; the given asset’s market value is before fees.
