Thanks for posting this, I found the format incredibly helpful, and it kind of makes me want to produce a run-rate estimator in a similar format. I often wind up overspending on side-project ideas for failing to take into account the costs of services I'll wind up using.

Judging by the Stripe fees, I'd hazard that your cumulative revenue is in the $30k range. I'm sure there are marketing and advertising expenses that aren't listed here, but that seems like a pretty healthy gross margin.
