About CalcCaddy
CalcCaddy is an independent library of practical calculators with visible formulas, editable assumptions, and clear limits.
Latest improvements — October 17, 2026
Concrete, room and roof workflows now include editable what-if comparisons that show how thickness, room dimensions and mixed pitches change whole-package quantities. Published check cases expose the inputs, expected answers and calculation boundaries. Price displays distinguish illustrative assumptions from observed market data.
These are software and content improvements, not completed construction projects. Independent participant testing of this update is pending; no user results or professional endorsements are claimed.
Useful numbers, without the black box
CalcCaddy helps homeowners, makers, and project planners turn measurements into useful material, quantity, and cost estimates. The calculators run in the browser, require no account, and show the reasoning behind the result.
How the tools are built
Each calculator starts with a documented formula, practical input defaults, a worked example, and plain-language assumptions. Where a standard or manufacturer specification applies, the calculator links to it. Where conditions vary, the value stays editable.
Regional pricing
Selected material calculators add a regional planning range based on state-level price-adjustment data. These ranges provide local context, not a supplier quote. The methodology and its limits are explained on the pricing methodology page.
Independence and limits
CalcCaddy is not a contractor, engineer, architect, code official, manufacturer, or materials supplier. The site currently has no active advertising or affiliate placements. Estimates should be checked against field measurements, product instructions, local codes, and qualified professional guidance when safety or compliance is involved.

What CalcCaddy publishes
CalcCaddy is a collection of free browser-based calculators and practical guides for construction, home projects, automotive comparisons, 3D-print pricing, and other measurable decisions. The tools are designed for people who want a usable estimate and enough visible math to check it.
Calculations run on the visitor's device. No account is required, and project measurements are not stored by CalcCaddy as saved customer records. Anonymous usage events may be used to understand which tools are opened and where an interface needs improvement.
How the site improves
New tools begin with a specific planning question and a formula that can be explained. Existing tools are revised when a formula, unit, assumption, source, or interface can be clearer. Published review dates identify the latest documented check, while detailed methods are available on the calculator methodology page.
CalcCaddy does not buy reviews, votes, testimonials, or editorial placement. Questions and correction reports can be sent through the contact page.
Who is responsible for CalcCaddy?
