I agree that it's difficult to know exact numbers at the seeds stage, but it's good to do some sort of exercise on user/customer acquisition costs, expected margins (particularly important in case of h/w products or online-offline work startups) etc.. It will help - 1. to know how long will this money last 2. can you build good business (even though it may not be profitable) before next round of financing.
And founders who do this exercise really set themselves apart as they know their business and gives strong signal to investors. Moreover, investors that I've spoken to often talk that they fund startups not only based on growth, or existing business but also ability to raise next round.
