Calculation methodology

The formulas and limits behind WreathMargin.

The calculators separate revenue, cost, fees, and profit so changing one assumption does not quietly change the meaning of another.

Wreath pricing

Craft materials are the frame, mesh, ribbon, florals, focal pieces, and consumables. Waste applies only to those craft materials. Packaging, labor, overhead, and postage are added separately.

True fulfilled cost = materials + material waste + packaging + labor + overhead + actual shipping

Required checkout revenue = (true fulfilled cost + fixed fee) ÷ (1 − percentage fee − target margin)

Suggested item price = required checkout revenue − buyer-paid shipping

Ribbon and mesh costing

Cost per foot = roll price ÷ (roll yards × 3)

Adjusted feet per wreath = measured feet × (1 + waste rate)

Cost per wreath = adjusted feet × cost per foot

Whole-wreath yield rounds down. Rolls required for a planned quantity round up.

Important limits

  • Margin is gross planning margin, not taxable income or an accounting opinion.
  • Fee presets exclude optional services unless their note explicitly includes them.
  • Carrier prices require the real packed dimensions, weight, origin, destination, and service.
  • A calculated price does not prove customer demand or guarantee a sale.
