Price Calculator by PluginOS

Sell products by weight, length, or area. Customers enter their measurements and get an instant, accurate price they can add straight to cart.

• Measurement-based pricing. Weight, length, and area (L×W) calculators with unit conversion, tiered quantity pricing, and min/max price clamping.
• Wastage buffer & add-ons. Add a cutting-waste percentage and stackable extras (lamination, rush order) with a full price breakdown.
• Accurate checkout. Calculated prices are charged as real variants, so cart, checkout, tax, and shipping all just work.
