Plan budget backwards from a revenue goal. Margin-aware break-even, full funnel math, and a verdict. Adjust inputs; everything recalculates live.
Planning math assumes your stated CVR/close rate hold at scale. Real budget increases drift: doubling spend rarely doubles conversions — expect ~1.5–1.7× at 2× spend (auction + audience saturation). Treat outputs as a starting target, then verify against live data.
