Why MaterialCalc

Home-project calculators get two things wrong more often than not: they either hide the math (so you don't know if the answer is right) or they quietly round up to sell you more than you need. MaterialCalc does neither.

We show the work.

Every calculator displays the intermediate steps — wall area, volume, waste factor — so you can sanity-check the output against your own mental model. If the number looks wrong, you can see why.

Waste factors are visible and adjustable.

Most online calculators bake in a 15–20% waste factor and never tell you. MaterialCalc shows you the number (usually 10%), explains what it covers (spills, cutoffs, touch-ups), and lets you set it yourself. Experienced DIYers often run tighter.

One-tap shopping lists.

Every tool has a Copy shopping list button. Tap it, and you've got a plain-text summary of exactly what to buy — drop it into the Home Depot or Lowe's app, send it to a contractor, or paste it into your notes.

Mobile-first, zero friction.

Most calculator sites are half-broken on a phone — cramped inputs, ads piled around the result, calculations hidden behind a submit button. MaterialCalc puts the input above the fold on a 375px screen and updates the output as you type. You'll never hunt for a submit button.
