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&#x27;ll wind up using.<p>Judging by the Stripe fees, I&#x27;d hazard that your cumulative revenue is in the $30k range. I&#x27;m sure there are marketing and advertising expenses that aren&#x27;t listed here, but that seems like a pretty healthy gross margin.
