Channeltics - YouTube channel sponsorship & paid collaboration calculator

I built this because I kept seeing the same problem over and over: YouTube sponsorship pricing is mostly guesswork. Creators undercharge or overcharge, brands overpay, and everyone relies on rough comparisons that don’t really reflect a channel’s actual value. The idea came from trying to answer a simple question more fairly: what is a channel actually worth for a paid collaboration? Not based on vibes or screenshots, but on signals that matter like median views, engagement, niche CPMs, and audience geography. From there, I tried to turn those messy signals into something usable. The goal wasn’t to perfectly “price” creators, but to give a defensible range people can use as a starting point in negotiations. The process was a lot of iteration: testing different weightings, comparing against real-world deals, and adjusting when the estimates felt unrealistic in either direction. Still refining it, so I’m mainly looking for honest feedback: does this match how you think sponsorship pricing works in practice? What’s missing, or what would break your trust in a number like this?
