How the math works

Monthly opt-ins = funnel traffic × opt-in rate. Sales-page visits = opt-ins × email open rate × email CTR. Expected sales = sales-page visits × sales-page conversion. Gross revenue = expected sales × product price. Net after ad spend = gross revenue − ad spend; this is before product costs, fees, refunds, taxes, or labor. Ad-spend ROI = net after ad spend ÷ ad spend and is not calculated when ad spend is zero. Break-even sales-page conversion = ad spend ÷ (sales-page visits × product price). These are user-entered scenarios, not forecasts.
