CalcShed Overview

CalcShed is a free web-based calculation platform built for construction, electrical work, concrete, roofing, landscaping, and home improvement planning. It is designed to make common project calculations easier to understand and check without requiring specialized desktop software, subscriptions, or account registration.

The platform includes calculators for concrete quantities and costs, slabs, footings, concrete blocks, bricks, framing and lumber, roofing materials, siding, insulation, decks, landscaping, electrical loads, wire sizing, voltage drop, Ohm’s Law, and other residential construction and trade calculations. Tools are grouped into focused categories so users can move between related calculations during the same project instead of relying on several unrelated websites or software products.

CalcShed focuses on showing how results are produced rather than returning a number with little context. Where relevant, calculators display the formulas, assumptions, and units used in the calculation. Many tools support both U.S. customary and metric units and include practical settings such as waste allowances, project dimensions, material sizes, openings, thicknesses, or other inputs that affect the result. Some calculators also include diagrams, visual measurement guidance, material breakdowns, cost-planning ranges, comparison tables, and multiple result formats.

The tools are mainly intended for early project planning, quantity estimation, budgeting, comparison, and calculation checking. A homeowner might use CalcShed to estimate concrete for a slab, roofing materials for a replacement project, or mulch for a garden bed. A contractor or tradesperson can use the site for quick planning calculations, while students can use electrical and construction calculators to work through formulas and understand how changing an input affects the result.

CalcShed is intended to support practical decision-making, not replace professional engineering, local code requirements, supplier quotations, construction drawings, or project-specific advice when those are required. Calculators that rely on external standards, technical references, or market data identify their methodology and relevant assumptions where appropriate.

The platform runs directly in a modern web browser and is designed for both desktop and mobile use. No installation is required. CalcShed emphasizes fast loading, straightforward interfaces, transparent calculation methods, and useful project guidance rather than complex enterprise project-management features.

Melt Bid

MeltBid by MeltPlan is an AI bid leveling agent built for general contractors in preconstruction. The traditional bid leveling process takes estimators hours of manual work — cross-referencing PDFs, building spreadsheets by hand, and hoping nothing slips through the cracks. MeltBid compresses that down to minutes.
