Our Mission
At Calcady™, we believe math should never be intimidating — it should be empowering. Our mission is to provide clear, accessible, and practical calculation tools across everyday life: from personal finance and fitness to specialized calculations for electrical, plumbing, welding, and construction trades.
Whether you're estimating the interest on a 30-year mortgage, checking voltage drop on a branch circuit, calculating water weight in a commercial pipe run, or figuring out your daily caloric target — we want every calculation to be fast, clear, and mathematically transparent.
Clutter-Free Utility. Zero Distractions.
The web is filled with calculation websites buried beneath aggressive advertisements, slow page loads, and confusing pop-ups. Calcady™ is built differently. We focus on clean, focused utilities designed for speed, clarity, and ease of use on desktop or mobile.
Standards-Based Methodology
Where calculations depend on established trade codes or external methodologies, Calcady builds directly upon published engineering standards, model codes, and accepted mathematical equations:
- Electrical: Wire size, voltage drop, and conduit fill calculations follow published methodology in the National Electrical Code (NFPA 70 / NEC), using standard conductor resistivity and ampacity tables.
- Plumbing & Hydraulics: Pipe friction loss calculations utilize the classic Hazen-Williams formula. Drainage and fixture demand models reference published International Plumbing Code (IPC) guidelines.
- Construction: Concrete volume, rafter spans, stair geometry, and wind pressure calculations reference standard framing geometry and model building guidelines (IRC / IBC / ASCE 7).
- Welding: Arc heat input, weld metal volume, and preheat temperature calculations align with published definitions in the AWS D1.1 Structural Welding Code.
- Financial: Amortization, compound interest, and investment equations use standard actuarial and time-value-of-money mathematics.
- Health & Fitness: Body mass, metabolic rate, and body composition estimators reference published clinical equations such as Mifflin-St Jeor, Karvonen, and the US Navy circumference method.

Our Core Values
- Mathematical Transparency: We show the underlying equations, variable definitions, and assumptions so you can understand and verify how results are calculated rather than treating the tool as an opaque black box.
- Absolute Privacy: Your data is yours. Calculations run 100% inside your browser using client-side JavaScript. Numbers you type never get transmitted to our servers or stored in remote databases.
- Educational Clarity: We believe in explaining the principles behind the numbers. Integrated reference notes and walkthrough sections provide background physics, standard code references, and practical trade context.
- Professional Respect: Our Trade tools are designed as practical planning aids. They do not replace formal engineering drawings, stamped calculations, or the on-site judgment of a licensed trade contractor. The final call always belongs to the qualified professional on the job.
Operator Transparency & Independence
Calcady™ is an independently developed and solo-operated computational utility. We do not claim institutional affiliations, corporate board oversight, or artificial editorial committees.
Every tool, formula citation, and educational guide is researched, implemented, and maintained directly by an independent software engineer and computational enthusiast, referencing authoritative published standards (such as the NEC, ASCE, IBC, and peer-reviewed journals).
Built for Practical Use
Calcady™ was built out of a desire for fast, clear, and unencumbered tools to solve real-world calculation problems — whether planning home improvement projects, budgeting finances, understanding health metrics, or preparing field estimates. These tools are freely accessible to everyone.
