Use this as a back-of-envelope planner. Start from the revenue target; walk backwards through win rate, average deal size, meeting-to-opportunity rate and reply-to-meeting rate. If the numbers look impossible, the plan is impossible.
Target ARR / Average deal size = deals needed. Deals / win rate = opportunities. Opportunities / opp-conversion = qualified meetings. Meetings / meeting-to-reply = replies. Replies / reply rate = emails sent. Emails / sends per inbox / working days = inboxes needed.
If you need more than 12 warmed inboxes to make the math work, you almost certainly have an ICP or offer problem, not a volume problem.
A Google Sheets version of this calculator is available on request.
