How is the market tax calculated?

2026-08-26 2 min read
Short answer

A 3% tax is taken on every item you sell in the Moradon market. You get 97% of the sale price, so the math is one line: price × 0.97. If you want a set amount to stay in your hand, divide that amount by 0.97 and list at the result.

Who pays the tax, when is it taken

The seller pays the tax. The buyer pays the price written in the listing, the system takes 3% of that price and credits the rest to the seller.

There are two formulas. Tax taken = listing price × 0.03. What you get = listing price × 0.97.

The tax rate doesn't change by item type. Whether you sell a weapon or armor, it's the same 3%.

If you sell at this price, what you get

Listing price GB Tax taken What you get
100,000,000 1 3,000,000 97,000,000
250,000,000 2.5 7,500,000 242,500,000
500,000,000 5 15,000,000 485,000,000
1,000,000,000 10 30,000,000 970,000,000
2,500,000,000 25 75,000,000 2,425,000,000
5,000,000,000 50 150,000,000 4,850,000,000
10,000,000,000 100 300,000,000 9,700,000,000

1 GB = 100,000,000 coins. On a 10 GB sale, 0.3 GB goes to tax.

If you want this much to stay in your hand, what to list at

Net you want Listing price Tax taken
50,000,000 51,546,392 1,546,392
100,000,000 103,092,784 3,092,784
500,000,000 515,463,918 15,463,918
1,000,000,000 1,030,927,835 30,927,835
5,000,000,000 5,154,639,175 154,639,175

Formula: net you want ÷ 0.97. Because there are no fractions of a coin, the result is rounded to a whole number.

Adding 3% on top of the price doesn't cover the tax. The right addition is about 3.09%. Dividing by 0.97 does that for you.

What to know when buying and selling

  • Your break-even price isn't 3% above your buying cost. It's buying cost ÷ 0.97. List below that and you lose.
  • No tax is taken on a sale you make by trade. But you have to trust the other side.
  • Work out the profit percentage on the buying cost, not the sale price. Net profit after tax divided by buying cost.
  • As the amount grows so does the tax. On a 10 GB sale 30 million coins go, which is 0.3 GB.

Find out whether a trade made a profit

  1. Write down the coins you paid for the item. We call that the buying cost.
  2. Divide the buying cost by 0.97. The result is your break-even price.
  3. Put the listing price above your break-even price. The gap is your net profit.
  4. Divide the net profit by the buying cost. If the percentage is small, waiting may not be worth it.

Frequently asked

The seller. The buyer pays the price in the listing and nothing more. The deduction is made from the amount the seller will get.

No. If you sell an item you bought at 100,000,000 for 103,000,000 after adding 3%, the tax is 3,090,000 and you get 99,910,000. You're 90,000 coins down. The right price is 103,092,784.

No, there's no deduction on a trade. But there's no market protection either. You have to trust the other side to hand over what you agreed.

Yes. On sales in the Moradon market the rate is 3% and it doesn't change by item type. The calculator works on a fixed 3% too.
