NFT Floor ROI Calculator
Calculate your actual profit or loss when selling an NFT at the current floor price, after deducting marketplace fees and creator royalties. Useful for deciding whether it's worth listing your NFT right now.
About this calculator
When you sell an NFT, you don't keep the full sale price — both the marketplace and the original creator take a percentage cut. The net profit formula is: Net Profit = currentFloor × (1 − royaltyPercent/100 − marketplaceFeePercent/100) − purchasePrice. The royaltyPercent goes to the NFT creator every time the asset changes hands, typically ranging from 2.5% to 10%. The marketplaceFeePercent is charged by platforms like OpenSea or Blur, usually 0.5–2.5%. Together these fees can consume 10–15% of your sale price, meaningfully shifting whether a trade is profitable. Understanding the break-even floor price — where proceeds exactly equal your purchase cost — is critical for any NFT trader.
How to use
You bought an NFT for 1.5 ETH. The current floor is 2.0 ETH. The creator royalty is 5% and the marketplace fee is 2.5%. Step 1 — Total deduction rate: 5% + 2.5% = 7.5%, so you retain 92.5%. Step 2 — Net proceeds: 2.0 × (1 − 0.075) = 2.0 × 0.925 = 1.85 ETH. Step 3 — Subtract purchase price: 1.85 − 1.5 = 0.35 ETH net profit. Despite a floor increase of 0.5 ETH, your actual take-home gain is only 0.35 ETH after fees.
Frequently asked questions
How do NFT creator royalties affect my profit when selling?
Creator royalties are a percentage of the sale price automatically paid to the original NFT artist or project team on every secondary sale. They typically range from 2.5% to 10% and are enforced at the smart contract or marketplace level. On a 2 ETH sale with a 7.5% royalty, you forfeit 0.15 ETH to the creator before accounting for any other costs. Some newer marketplaces have made royalties optional, which can improve seller returns but undermines creator revenue streams.
What is the break-even floor price for an NFT investment?
The break-even floor price is the minimum sale price at which you recover your purchase cost exactly, after all fees. To calculate it, divide your purchase price by (1 − royaltyPercent/100 − marketplaceFeePercent/100). For example, if you paid 1.5 ETH and total fees are 7.5%, the break-even floor is 1.5 / 0.925 ≈ 1.622 ETH. Selling below this price results in a net loss even if the nominal floor appears higher than your cost basis.
Which NFT marketplaces charge the lowest fees for sellers?
Marketplace fees vary and change frequently as platforms compete for volume. As of recent market conditions, Blur has attracted traders with reduced or zero royalty enforcement and low platform fees, while OpenSea charges around 2.5%. Some platforms allow creators to set royalties as low as 0%, while others enforce a minimum. Before listing, always verify the current fee structure on the specific marketplace, as even a 1% difference in fees can be meaningful on high-value NFTs.
