About CALQUNIX

CALQUNIX provides free, straightforward calculators for home improvement and DIY projects. Our goal is to help you plan quantities and budgets before buying materials.

What is available?

Our tile calculator estimates tile quantities, boxes and cost. Our paint calculator estimates wall and ceiling paint, coats, full containers and purchase cost. Our concrete calculator estimates slab volume, bag quantities and material cost. All three tools support metric and US customary units. A flooring calculator is planned but not yet available.

How to use our results

Calculations are planning estimates, not installation designs or professional quotations. Confirm the layout, materials, manufacturer coverage and waste requirements with your supplier or installer before purchasing.
