Hey PH community! I built CalcShed because I kept running into the same problem — every construction calculator site was cluttered, slow, or gave a number with zero context about what it meant.
CalcShed covers 50+ calculators across concrete, roofing, framing, electrical, and landscaping. Each one has 2025–2026 US pricing data, waste factor options, imperial/metric toggle, and an explanation of what the result means for your project.
Completely free, no account needed, and every calculator can be embedded on other websites via a copy-paste iframe code - great for contractor blogs or home improvement sites.
Happy to answer any questions about the build or the niche!
