How the calculator works

For ordinary taxable items, the calculator applies 2% of each item’s sale price, rounded down, with a maximum fee of 5,000,000 gp per item. The total is the per-item fee multiplied by quantity.

Some items are exempt. This compact calculator assumes the item is taxable; use the live trading desk for item-aware calculations. It also excludes price movement, failed fills and slippage.
