Two layers of value: shipping savings from aggregated marketplace volume, plus net new marketplace revenue. Numbers update live as you change inputs.
How the math works
Shipping savings = (your current rate − Fast Aquatics' negotiated rate) × your monthly box volume × 12. Fast Aquatics rate scales with our aggregate volume: Phase 1 (Q1-Q2 2026): $42 avg, Phase 2 (Q3-Q4): $38 avg, Phase 3 (year 2): $35 avg.
Net new revenue = expected new orders × your AOV × (1 − take rate) − monthly subscription × 12. New orders attribution conservatively assumes 60% incrementality (some buyers would have found you elsewhere).
"Without Fast Aquatics" baseline uses your current shipping cost and zero net new orders. "With Fast Aquatics" uses the negotiated shipping rate and adds the net new orders.
Numbers exclude PayPal/Square processing fees (vendor pays those either way).
Wholesale orders not modeled — they're upside on top of this.
