NFT Royalty Calculator
Calculate creator royalties earned from secondary NFT sales across marketplaces. Enter values for instant results with step-by-step formulas.
Formula
Royalty = Sale Price x Royalty % | Monthly = Collection Size x Sale Rate x Royalty
Royalty per sale is the sale price multiplied by the creator royalty percentage. Monthly royalty income is estimated by multiplying the collection size by the monthly secondary sale rate and the royalty per sale. Marketplace fees are deducted separately from the seller, not the creator.
Worked Examples
Example 1: 10K Collection Monthly Royalty Projection
Problem: A 10,000 NFT collection with 5% royalty, average secondary sale price of 2.5 ETH, 5% monthly sale rate, ETH at $3,000.
Solution: Royalty per sale = 2.5 ETH x 5% = 0.125 ETH ($375)\nMonthly secondary sales = 10,000 x 5% = 500 sales\nMonthly royalties = 500 x 0.125 = 62.5 ETH ($187,500)\nAnnual royalties = 62.5 x 12 = 750 ETH ($2,250,000)\nMarketplace fee (2.5%) = 0.0625 ETH per sale\nSeller receives = 2.5 - 0.125 - 0.0625 = 2.3125 ETH
Result: Monthly: 62.5 ETH ($187,500) | Annual: 750 ETH ($2,250,000)
Example 2: Small Artist Collection Earnings
Problem: An artist has 500 NFTs with 7.5% royalty, average 0.5 ETH sale price, 3% monthly sale rate, ETH at $3,000.
Solution: Royalty per sale = 0.5 x 7.5% = 0.0375 ETH ($112.50)\nMonthly sales = 500 x 3% = 15 sales\nMonthly royalties = 15 x 0.0375 = 0.5625 ETH ($1,687.50)\nAnnual = 0.5625 x 12 = 6.75 ETH ($20,250)\nBreak-even: mint cost 500 x 0.05 = 25 ETH\n25 / 0.0375 = 667 secondary sales needed
Result: Monthly: 0.5625 ETH ($1,687.50) | Break-even after 667 secondary sales
Frequently Asked Questions
What are NFT royalties and how do they work on different marketplaces?
NFT royalties are a percentage of the sale price that is automatically paid to the original creator each time an NFT is resold on a secondary market. When a creator mints an NFT, they can encode a royalty percentage (typically 2.5 to 10 percent) into the smart contract. Each subsequent sale triggers this payment automatically through the blockchain. However, royalty enforcement varies significantly by marketplace. OpenSea enforces creator royalties through its platform but does not do so on-chain by default. Blur initially made royalties optional to attract traders, then introduced minimum 0.5 percent royalties. Marketplaces like Foundation and SuperRare consistently enforce royalties. The EIP-2981 standard provides a royalty info interface but enforcement remains marketplace-dependent rather than protocol-level.
What is the difference between primary sales revenue and royalty income?
Primary sales revenue comes from the initial mint or first sale of an NFT directly from the creator to the buyer. The creator receives the full sale price minus any marketplace fees and gas costs. This is typically a one-time event per NFT. Royalty income, by contrast, is an ongoing passive revenue stream generated every time the NFT changes hands on secondary markets. While primary sales provide immediate large payouts, royalties compound over time as collections gain traction. A successful 10,000-piece collection at 0.1 ETH mint price generates 1,000 ETH in primary sales. If each piece trades an average of 5 times over its lifetime at an average price of 0.5 ETH with 5 percent royalties, that generates 2,500 ETH in total royalties — 2.5 times the primary revenue.
Can NFT royalties be avoided and what protections exist for creators?
Unfortunately, royalty avoidance is a significant issue in the NFT ecosystem. The most common method is over-the-counter (OTC) trading where buyers and sellers transact directly via simple wallet transfers, completely bypassing marketplace royalty enforcement. Some marketplaces like Blur and SudoSwap made royalties optional, allowing buyers to skip them. Technical workarounds include wrapping NFTs in new contracts or using marketplace-specific listings that minimize royalty payments. To combat this, creators can implement on-chain enforcement through tools like OpenSea Operator Filter Registry, which blocks marketplaces that do not honor royalties. ERC-721C by Limit Break offers more robust on-chain enforcement. Community-based approaches include restricting holder benefits to those who purchased through royalty-honoring channels, creating social incentives to support creator compensation.
