Affiliate disclosure

Affiliate Disclosure

Some links on BuildCalc may be affiliate links. If you buy through one, we may earn a commission — at no extra cost to you.

Last updated: 10 November 2026.

How it works

BuildCalc is free to use. To keep it free, some pages link to retailers and manufacturers where you can buy the materials the calculator estimates — paint, tile, flooring, concrete, mulch and so on. Some of those links are affiliate links: if you click one and buy something, the retailer may pay us a small commission. The price you pay does not change.

What it does not change

Affiliate links never change a calculator result, a guide recommendation, or which products we mention. The numbers come from manufacturer coverage data and standard trade formulas, not from any retailer, and no retailer pays us to be recommended. A guide recommends a product because it fits the job, not because it pays a commission. See our Editorial Policy.

What we do not do

We do not state prices as facts — prices vary by store and region, so check the price at the store you buy from. We do not track what you buy, and we do not receive your name, address or payment details from any retailer.
