    The exact math behind these numbers

    No black box. Every figure is a direct calculation from what you typed, here is the chain in full.

    Today

    Monthly bookings are visitors × CR. Monthly revenue is bookings × AOV × take rate, where take rate is 100% unless you set it (so a marketplace sees the revenue it keeps, not gross order value).

    After the lift

    The lift is relative, so the new rate is CR × (1 + lift), a 15% lift on a 2.2% rate gives 2.53%, not 17.2%. New bookings are visitors × new CR. Because traffic and AOV are unchanged, the only thing that moves is conversion.

    Money on the table

    Incremental bookings per month are visitors × CR × lift. Incremental revenue is incremental bookings × AOV × take rate, and the annual figure is simply × 12. The scenario table reruns the same formula at fixed relative lifts of 5%, 10%, 15%, 25% and 40%.

    What it assumes

    That traffic, AOV and take rate hold steady, that the lift is sustained rather than a one-off spike, and that your conversion rate is measured cleanly. It's a sizing tool, not a forecast, it tells you how much the prize is worth so you can judge whether the work to win it pays off. It deliberately ignores the cost of that work; that's a conversation, not a constant.
