Have you ever come to a situation when the product price needs a custom mathematical formula depending on the product options selected? This extension provides pricing for your products having the complex pricing structure which depends on some mathematical formula. For example: {width}*{height}*{price} OR ({Pi}*({Radius}*{Radius})) (in this formula Pi= 3.14 which needs to be defined in static variables for equation) OR {width}*{height}*{option-one_price}+({width}+{height}*1.5) OR {length}*{width}*{height}*{price} and so on...

When you install and enable this extension, it will add a formula pricing tab in product page(admin area) where you can write a custom formula to calculate the price. You can also define static variables in the "Static Variables For Equation" (text area) and use them in the custom formula for price calculation. The system will use the defined formula to calculate the product price.

This extension allows you to calculate prices of multi-dimensional, variable sized products like Liquids sold in volume, Blinds sold in length and width, Fabric in meter or yard Flooring sold in square feet, Variable mulch sold in the cubic yard, Wallpaper sold based on wall dimensions, Printing and Banners store, Foam sold in the cubic foot, Fencing for house or garden, Tarps sold in meter, Wrapping paper sold according to surface area etc.
