Show HN: MRR Take-Home Calculator for Bootstrapped Founders (opens in new tab)

I keep seeing posts like "we hit $2.5k MRR!" and my first thought is always: okay but what does that actually net?

After the 30% Apple cut, Stripe fees, and depending on your structure (taxes) the number looks pretty different. And then I want to work backwards: how many users do I need at what conversion rate to get there?

I was doing this in Claude every few weeks. Felt like a waste, so I built a calculator instead.

Handles sole proprietors and LLCs, US and UK, major app stores and payment processors. Shareable URLs so you can bookmark your scenario or drop it in a Slack thread.

That link is pre-filled: $9.99 ATV, 5% conversion, Apple App Store, sole proprietor. Tweak to your situation.

Happy to add more processor/store combos if there's demand. What's missing?
