Merchants often struggle to display real-time pricing for products sold by volume, length, weight, or decimal quantity. That’s where Custom Price Calculator helps, allowing you to add a measurement price calculator to display prices based on custom formulas automatically. By using basic formulas (e.g, length x width), you can show per-unit cost based on the user's input value. For each rule, you can set alternative conditions that are applied when the user input satisfies the specific criteria.
