I built a free calculator that shows what a heavy user actually costs you per month

One of the two walls I hit building an AI product: i could see my total model bill, but not what any single customer cost me. and a heavy user on an "unlimited" plan can quietly turn your margin negative for weeks before you notice.

So i made a small free tool. you put in your model, tokens per interaction, and how much heavier your power users are, and it shows the cost of a typical vs heavy customer and the price that actually protects your margin. no signup to use it.

Would love a sanity check on the assumptions, does the typical-vs-heavy gap match what you've seen in your own usage? (this metering is baked into LaunchAI, which launches here Aug 1, but the calculator is free and standalone.)
