What is NFT Royalty Calculator?
NFT Royalty Calculator is a free, browser-based tool in the Web3 & Crypto suite. Compute the net royalty a creator receives from an NFT sale after marketplace and platform fees. Enter sale price, royalty percentage, and platform fee, then see the net payout.
The headline benefit: calculate nft creator royalties after marketplace fees — see what you actually earn.
Unlike most online tools that upload your file to a server, process it, and send it back, NFT Royalty Calculator runs entirely in your browser. Open DevTools → Network while using it and you'll see zero file-upload requests — only static assets (JavaScript, CSS, fonts) load. Your data never leaves your device.
Why use this nft royalty calculator?
Three reasons EasyFileKit's NFT Royalty Calculator stands out from the crowd:
Private by design — all processing happens locally via JavaScript and WebAssembly. No server ever sees your input.
Instant — no upload wait, no queue, no server round-trip. Results appear the moment you act.
Free & unlimited — no accounts, no watermarks, no daily caps. Use it as many times as you like.
How to use NFT Royalty Calculator — step by step
Here's the complete walkthrough. Everything happens instantly in your browser:
Step 1. Enter the NFT sale price in your preferred currency.
Step 2. Set the creator royalty percentage (typically 5-10%).
Step 3. Enter the marketplace fee percentage (e.g. 2.5% for OpenSea).
Step 4. Read the gross royalty, platform fee, and net creator payout.
That's it. No sign-up, no upload bar, no waiting. If something doesn't work as expected, check the FAQ below.
Common use cases for NFT Royalty Calculator
People reach for NFT Royalty Calculator in a few recurring situations:
When you need the result now and can't wait for a server-based tool to upload, queue, and process your file.
When your file is private or sensitive — financial documents, personal photos, medical PDFs — and you don't want it travelling across the internet.
When you're on a slow or metered connection — uploading a 50 MB file just to compress it makes no sense when the same work can happen locally.
When you've hit the daily limit or paywall on another "free" tool site.
Privacy: what actually happens to your data
This is the single most important point about NFT Royalty Calculator, so it deserves its own section.
You can verify this yourself in under 30 seconds:
Open NFT Royalty Calculator in your browser.
Press F12 to open DevTools.
Switch to the Network tab and tick "Disable cache".
Use the tool — drop a file, type text, whatever the tool needs.
Watch the Network log. You'll see only static assets (JS, CSS, fonts, icons). No request contains your data.
This isn't a setting you toggle or a promise in a privacy policy — it's how the tool is architecturally built. There is no upload endpoint to call.
NFT Royalty Calculator: EasyFileKit vs server-based tools
Most "free" online tools that do what NFT Royalty Calculator does follow the same model: you upload your file to their server, they process it with a backend script, then they send the result back. Here's the honest comparison:
| Feature | EasyFileKit | Server-based tools |
|---|---|---|
| Speed | Instant (no upload) | Slower (upload + queue + download) |
| Privacy | Complete | Your file is on someone else's computer |
| Cost | Free, unlimited | Often capped or "premium" gated |
| Works offline | Yes (PWA) | No |
|---|---|---|
Server-based tools aren't evil — they exist because some tasks genuinely need heavy backend compute. But for everything NFT Royalty Calculator does, client-side processing is strictly better for you.
Under the hood: how NFT Royalty Calculator works
NFT Royalty Calculator is built with modern browser APIs. Depending on what it does, it may use:
Canvas API — for image manipulation (pixel-level access, filters, resizing).
Web Crypto API — native, hardware-accelerated cryptography (AES-GCM, SHA-256, PBKDF2) for any encryption or hashing.
pdf-lib / pdf.js — fully client-side PDF creation and rendering.
MediaRecorder API — for capturing screen, audio, and video.
WebAssembly — for heavy codecs (image compression, media processing).
All of these run inside your browser's sandbox. They cannot access your filesystem (beyond files you explicitly choose), cannot make network requests with your data, and cannot run persistently in the background.
Pro tips for getting the most out of NFT Royalty Calculator
Bookmark the tool — it works offline once cached, so you can use it even without a connection.
Install EasyFileKit as a PWA — open the browser menu and choose "Install app" for a standalone window and offline access.
Use it on mobile — every tool is fully responsive and works on phones and tablets, not just desktops.
No file size anxiety — because nothing uploads, you can process large files that server-based tools would reject or charge for.
