FAQ
How does the waitlist conversion calculator work?
Waitlists decay: not everyone opens, clicks or buys. This applies each step to project launch revenue and the list size needed to hit a target. The underlying maths is: Buyers = list × open × click × purchase rate.
What do I need to enter?
6 values: waitlist size, open rate, click rate of opens, purchase rate of clicks, price, and revenue target. Each field starts with a sensible default, so you can change one number at a time and watch the result move.
What does the projected launch revenue result mean?
It is returned as a money amount in US dollars and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds.
Is this calculator free, and do I need an account?
Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser.
How accurate is the result?
It applies the standard formula exactly, so the arithmetic is precise. Estimates assume standard, average conditions — local rules, pricing, and materials vary.
