Conversion Rate Calculator
Divide orders by visitors. 420 orders from 24,000 visitors is 1.75%. Set the target at 2.5% and the same traffic would produce 600 orders; getting to 600 without touching conversion needs 34,286 visitors — 10,286 more than you have. Put another way, lifting conversion by 0.75 points is worth as much as buying 43% more traffic.

Formula
Conversion rate = Orders ÷ Visitors × 100, Extra visitors needed = Orders at that rate ÷ (Conversion rate ÷ 100) − Visitors
The denominator moves the answer a lot. Sessions and unique people usually differ by 1.3 to 1.5 times, and leaving bots and internal traffic in drags the rate down. Splitting by device and channel shows what is pulling the average: as the mobile share grows, the blended rate falls even though nothing got worse.
