Product Calculator – do the math for your customers
The customer enters the dimensions and the calculator works out the quantity they need. Faster purchases, fewer returns, happier customers. Ideal for building supplies, flooring or tiles.
Product Calculator
When a customer is buying flooring, tiles or building materials, they often have no idea how much they actually need. That's exactly why there's the Product Calculator – a Shoptet add-on that does the math for them.
Just enter the dimensions and the calculator automatically works out the quantity or the number of packs needed. It handles 1D, 2D and 3D calculations, so it covers both floor area and room volume. Every calculation is customizable – in the settings you define your own dimensions, units and formula.
The benefit is obvious: customers buy the right amount the first time. No tedious math, no running out of material halfway through the job. And if you remind them to add a margin (waste from cutting, for example), you increase the average number of packs sold – and customers will thank you for it.
With the calculator, buying gets faster, easier and error-free – which means happier customers and fewer complaints and returns.
What the Product Calculator can do
-
1D, 2D and 3D calculations – length, area and volume.
-
Custom setup – your own dimensions, units and formulas.
-
A fast buying process – the customer knows right away how many packs they need.
-
Support for higher sales – the option to remind customers about a margin for cutting waste → more units sold.
-
Flexible use – universal for any product range where quantities need to be calculated.
Typical use cases
-
Flooring and tiles – the customer enters m² and instantly knows how many packs they need.
-
Roofing – calculated from the roof dimensions, including a margin.
-
Pool chemicals – quantity calculated from the pool volume.
-
Building materials – paving, bricks or insulation, for example.
-
B2B ranges – bulk material purchases that need an exact calculation.
How the setup works
You activate the add-on straight from your Shoptet admin. In the settings you choose the number of dimensions (1D/2D/3D), name them, assign units and define the formula. That way the calculator is fully tailored to your specific product range.
