RevenueLab.fyi | Real‑time revenue calculators & AI diagnosis for creators!

Hey Product Hunt! I’m Sam, the founder and sole builder of RevenueLab.fyi, and today I’m excited to finally launch it to the community. I built RevenueLab because I was tired of “seven‑figure” guru screenshots and AI‑generated listicles that don’t help you make decisions. When you’re deciding whether to go full‑time on YouTube or whether a client’s monthly retainer pencils, vibes aren’t enough – you need a model. What RevenueLab is RevenueLab is a growing library of revenue calculators and decision tools for creators, freelancers and indie operators. The calculators cover everything from YouTube RPM & CPM to freelance hourly rates, SaaS LTV:CAC, Google Ads ROAS, sponsorship CPM, Shopify/Amazon unit economics and more. Every calculator runs in your browser, shows its formula and assumptions and produces a URL you can bookmark and share. The site operates on a few simple principles: show the math, be transparent about uncertainty, and never lock tools behind a signup. It’s completely free, funded only by a few display ads and occasional affiliate links. There are no ghostwriters or AI‑generated bylines; everything is written or reviewed by me. Rex AI – an AI agent built for numbers, not vibes Generic AI tools are great for brainstorming, but they can’t pull your channel’s actual data or run deterministic revenue models. That’s why I built Rex AI, a real‑time agent that fetches your YouTube data, pulls live niche benchmarks and writes a custom revenue diagnosis. Paste your channel URL and, in ~10 seconds, Rex tells you where your RPM sits against your niche percentile, highlights the top plays to close revenue “leaks”, and gives a 12‑month projection. It’s different from ChatGPT because it uses live stats and benchmark data you won’t find in a 2023 training snapshot, and each report is a shareable URL you can send to a collaborator or sponsor. Saved scenarios & persistence One of the most requested features was the ability to save what‑if scenarios. All RevenueLab calculators and AI reports produce a persistent URL. You can tweak the inputs, copy the link and revisit it later – no account required. This makes it easy to compare different pricing models, share them with a friend, or embed them in a client pitch. The AI agent remembers the context of your channel and the scenario you’re modelling, so you can iterate without re‑entering everything. Why this matters in an AI‑saturated world In a world where AI chatbots spit out generic advice, RevenueLab adds value by pairing real‑time data with transparent models. Rex AI doesn’t hallucinate – it pulls your actual subscriber counts and upload cadence, ties them to live CPM benchmarks, and runs deterministic math. The broader site is committed to showing the formulas behind every result and updating them when assumptions change. You get the benefits of AI (speed and convenience) without giving up accuracy or transparency. What’s next This is just the start. I’m already working on: More decision tools beyond YouTube – including SaaS pricing calculators, ad‑spend diagnostics and creator monetization scenarios. Scenario collections, so you can save multiple what‑ifs in one place and compare them side‑by‑side. Persistence across devices, so your saved scenarios follow you from desktop to mobile. 🙏 I’d love your feedback If you’re a creator, freelancer or SaaS founder who’s ever asked “will this pay off?”, RevenueLab.fyi was built for you. Check out the calculators, run Rex AI on your channel, and tell me which scenarios you’d like to see next. Let’s replace guesswork with clarity. Thanks, Sam
