A calculator is only as good as what you feed it. Three habits keep this from turning into a wishful spreadsheet.
Reach is not a pipeline. Count only the conversations you genuinely replied to, that is the input that produces revenue.
Warm inbound from X (Twitter) closes better than cold outreach, but not magically. If you do not know your rate, start at 2% and adjust once you have data.
Twenty minutes a day is two hours a week. If the revenue does not cover that at your hourly rate, the channel is not working yet.
This calculator assumes you can find the right posts to reply to. Finding them is the part that eats the time. The actual product monitors your keywords and competitors around the clock, scores each conversation for buying intent, and drafts the reply in your brand voice. Every reply still waits for your approval. If the number above looks worth having, the queue version is how you get the hours back.
