Calcs Builder is Calcs.com’s no-code platform for turning engineering logic into clean, interactive calculators—with units, validation, and shareable templates.
Replacing spreadsheets: Build calculators with structured inputs and equations (no fragile cell references), then publish a consistent tool your whole team can use.

Watch the overview

See how Calcs Builder helps teams move beyond spreadsheets—broken formulas, messy tabs, and inconsistent usage—into reusable, controlled templates.

How Calcs Builder works

Most calculators follow the same pattern:
  1. Inputs — collect values (dimensions, loads, materials) with units and constraints
  2. Equations — compute results using formulas, functions, and conditional logic
  3. Outputs — present clear results (and optional reports/exports)
  4. Publish — share a stable tool without exposing the underlying logic

Why teams use it

No-code, engineer-friendly

Build with widgets (inputs, equations, tables, diagrams) instead of spreadsheets or custom software.

Units + consistency

Keep calculations readable and reduce mistakes with explicit units and structured inputs.

Reusable + shareable

Publish templates so everyone uses the same logic—without editing formulas.

Common use cases

Use Calcs Builder for anything from quick checks to multi-step workflows, including:
  • Structural engineering: beams/columns, foundations, load combinations, retaining walls
  • Mechanical engineering: stress checks, thermal calcs, fluids, machine design
  • Custom applications: internal standards, proprietary methods, education, R&D
