About CalcCaddy
CalcCaddy is an independent library of practical calculators with visible formulas, editable assumptions, and clear limits.
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.
