CalcQuarry

Hi everyone, I'm Muhammad. I built CalcQuarry because most material calculators give you a number without saying how they got it. Every CalcQuarry tool shows the formula, density and waste allowance, and answers in the units suppliers sell (yards, tons, bags). There are 30+ tools so far for concrete, landscaping and carpentry. It's free with no signup. Which calculator should I build next?

Showing the formula, density and waste allowance next to every result is the right call, because it lets a contractor check a supplier's quote instead of trusting one number. A useful next step would be a short note on how the waste allowance should change for irregular shapes like curved patio edges, so people don't order too little or too much.

Showing the formula, density and a waste allowance is what makes this usable when checking a supplier quote, not just a rough guess. A gap for shops that buy from both US yards and European suppliers: cubic yards and tons do not map cleanly to cubic metres and 25 kg bags. A unit toggle that keeps the same formula but answers in cubic metres, tonnes and 25 kg bags would save redoing the math. If you add one calculator next, a footing or pad (length x width x depth) that also returns rebar cut length would cover small jobs the slab tools skip.

Showing the formula, density and waste allowance is the right call. It turns the tool into something a homeowner can use to check a supplier quote, not just a number to trust. To answer your question: a quote checker would be my pick. Paste the supplier's line items and see where the quantities or the waste margin look off. Also curious whether you plan metric units: a lot of DIY traffic outside the US searches in cubic metres and kilos.

Great work! Showing the formulas, density, and waste allowance alongside the final result makes these calculators much more trustworthy and practical. I especially like that the results use the units suppliers actually work with, saving people extra calculations. Having 30+ free tools in one place is a solid resource for contractors and DIY projects. Keep building! 💪

Showing the formula and waste allowance next to every result is exactly the right design choice — it turns the calculator from a black box into a teaching tool, so a contractor can sanity-check a supplier quote against the same math. I also appreciate that results come back in ordering units (cubic yards, tons, bags) rather than abstract numbers. One genuine question: does the tool account for regional differences in material density, or is that handled through a density input the user adjusts? No-signup and phone-friendly makes this genuinely usable on a job site. Nice work.

Showing the formula alongside each calculator is a smart touch for builders who need to justify supplier quotes. If you added an option for GST-inclusive vs exclusive pricing, this could become the default estimating tool for Indian contractors too. Do you plan regional price presets?
