NFT Royalty Calculator

How it is calculated

Both the creator royalty and the marketplace fee are taken as a percentage of the sale price, not of each other. royalty = sale_price × royalty% ÷ 100, platform_fee = sale_price × fee% ÷ 100, seller_proceeds = sale_price − royalty − platform_fee and seller_profit = seller_proceeds − original_price. The original price is what the seller paid to acquire the NFT; enter 0 if you minted it and want profit to equal proceeds. Prices are shown with a dollar sign and two decimals, so convert crypto amounts to a currency value first, or treat the dollar figures as a plain unit. The two percentages together cannot exceed 100 and the sale price must be above zero. Gas fees, currency conversion and taxes are not included, and whether the royalty is actually paid depends on the marketplace.

Common mistakes

• Adding the percentages the wrong way, such as taking the marketplace fee from the amount left after the royalty. Here both are taken from the full sale price, so check how your marketplace defines them.
• Entering a price in ETH and reading the dollar sign as dollars. The tool just formats numbers, so convert to one currency first or read the figures in your own unit.
• Leaving out the original price when you want profit. With 0 the profit equals the proceeds, which overstates your gain if you paid something for the NFT.
• Forgetting gas and network fees. They are not in this calculation, so real proceeds will be lower.
• Assuming royalties are always enforced. The tool shows what the percentage would be, but some marketplaces make royalties optional, so the amount actually paid can be less.
