How to Use
- Enter the purchase price in ETH (what you paid to mint or buy).
- Enter the sale price in ETH (gross proceeds from the buyer).
- Enter the total gas fees in ETH — sum of mint, list, and accept transactions.
- Enter the marketplace fee % (OpenSea 2.5%, Blur 0%) and creator royalty % (collection-specific).
- Enter the ETH price in USD and read net profit and ROI.
Calculation Method
marketplace_fee = sale_price × marketplace_fee_pct ÷ 100
royalty = sale_price × royalty_pct ÷ 100
net_eth = sale_price − purchase_price − gas_fees − marketplace_fee − royalty
net_usd = net_eth × eth_price_usd
roi_pct = net_eth ÷ purchase_price × 100
royalty = sale_price × royalty_pct ÷ 100
net_eth = sale_price − purchase_price − gas_fees − marketplace_fee − royalty
net_usd = net_eth × eth_price_usd
roi_pct = net_eth ÷ purchase_price × 100
- purchase_price

Examples
Example 1 — Mint at 0.5 ETH, flip at 1.2 ETH on OpenSea
Sale 1.2 ETH, purchase 0.5 ETH, gas 0.02 ETH, marketplace 2.5% = 0.030 ETH, royalty 5% = 0.060 ETH. Net = 1.2 − 0.5 − 0.02 − 0.03 − 0.06 = 0.59 ETH ≈ $2,254 at $3,820/ETH. ROI ≈ 118%.
Example 2 — Same flip on Blur (0% fees, no royalty enforced)
Same sale and purchase prices, but marketplace 0%, royalty 0%. Net = 1.2 − 0.5 − 0.02 = 0.68 ETH ≈ $2,598. ROI ≈ 136%. That 18-point spread is why volume migrated to Blur for pro flippers in 2023.
Frequently Asked Questions
In the US, yes — the IRS treats NFTs as property (and possibly as collectibles, taxed at up to 28% if held long-term). Each sale is a capital gain or loss event reported on Form 8949. Use our Crypto Tax Calculator to estimate the tax bill.
Not universally. OpenSea enforces them on most collections. Blur and X2Y2 made royalties optional in 2022-2023, and most pro flippers pay 0%. Some new collections use on-chain transfer hooks to enforce royalties at the protocol level.
OpenSea: 2.5% marketplace + collection-set royalties (usually enforced). Blur: 0% marketplace + optional royalties. Magic Eden: 2% + enforced royalties on its own creator tools. Always check current values — these change.
Mint + list + accept transactions can easily cost $50-$200 on L1 during congestion. On low-value flips (under 0.1 ETH), gas often eats half the profit. This is why most active flippers move to L2 NFT markets or wait for low-fee windows.
For HODL marking, yes — floor is the cheapest available. For your specific NFT, actual sale price depends on rarity and traits. Floor is a conservative estimate; rare pieces sell at significant premiums but also take longer to clear.
