Calculate the share of visitors who purchase and model revenue at different conversion rates.

Conversion rate (%) = conversions ÷ visitors × 100
If 250 of 10,000 visitors purchase, the visitor-based conversion rate is 2.5%. At an illustrative $50 average order value, those 250 orders produce $12,500 in revenue.
Use a consistent denominator. A visitor-based rate uses visitors; a session-based rate uses sessions. They answer different questions and should not be compared without that distinction.
Hold traffic and average order value constant, multiply traffic by the modeled conversion rate to estimate orders, then multiply by average order value. These scenarios are calculations, not forecasts.
