Price your AI-built app honestly: the ownership math that keeps you shipping

$Price your AI-built app honestly: the ownership math that keeps you shipping$

Shipping the first version of an app with AI help in a weekend is a genuine win — a solo builder can now reach a working product before the motivation fades. Then month three arrives with the question nobody asked during the build: what does this app actually cost to run, and which of those bills do I control? This post answers that with a six-line math sheet you can fill in for your own app in an afternoon.

The honest answer up front: most AI-built apps cost little to run and a lot to not own. The servers, payments, and store cuts are priced in public and easy to plan around. The expensive line is the one that never appears on an invoice — rebuilding what you cannot change. Work all six lines before you commit to a stack, and the math stays boring forever.
