MMO Trading Profit Calculator

Quick answer

This calculator computes real auction house profit after tax and fees.

  • Enter buy price, sell price, tax percent, and listing fee for your net gain.

Figures are estimates from this calculator’s standard formula — adjust the inputs in the tool below for your exact number.

How the Trading Profit Calculator Works

gross = sell - buy; tax = sell x rate; net = gross - tax - listing fee

Game markets skim a percentage of the sale. The tool subtracts that tax and the flat listing fee from your gross margin to expose the true profit.

  1. 1

    Enter trade prices

    Give your buy price and intended sell price.

  2. 2

    Enter market costs

    Add the auction tax percent and flat listing fee.

  3. 3

    Read net profit

    See gross, tax paid, and what actually lands.

FAQs

What is the net profit buying at 1000 and selling at 1500 with 5% tax and a 20 fee?

Gross is 500, tax takes 75, and the fee 20, leaving 405 net profit.

How is the tax amount computed?

On the full sale: 1500 x 0.05 = 75. Note it applies even when your margin is thin.

When does a flip become unprofitable?

When tax plus fee eat the spread: a 100 gross on a 2000 sale with 5% tax already loses 100 to tax alone.

Does the listing fee apply per attempt?

Yes in practice: the tool counts one fee per listing, so relisting unsold goods repeats the fee.
