About ConstrCalc®

Our Mission

Give every builder — from the solo remodeler to the multi-story GC — an estimation tool that respects their inputs, refuses to invent numbers, and works on any device without a signup.

What ConstrCalc Is

ConstrCalc^® is a professional construction cost & engineering calculation platform. Its core is a six-tab workflow — Project Info, Legal Documents, Materials, Labor, Equipment, Summary — that mirrors how estimators actually think through a bid.

It runs in your browser. It saves your work locally. It exports in every format you need. And it never, ever adds numbers you didn't enter.

What ConstrCalc Is Not

• Not a proposal-writing tool. Use the PDF export in your existing workflow.
• Not a CRM. It doesn't track leads or clients.
• Not a project management platform. It's an estimator. Focused.
• Not a black box. Every formula is on the methodology page.

Who It's For

• General contractors preparing bids
• Sub-contractors quoting scope
• Architects doing feasibility studies
• Civil engineers checking budgets
• Real-estate developers running pro-formas
• Home-owners pricing renovations
• Estimators everywhere

How We Fund It

Google AdSense on clearly-marked slots. The calculator itself is ad-free during use.

Our Promise

The Construction Calculator will NEVER: make assumptions, modify your values or rates, change formulas, generate hidden calculations, or generate fake calculations. If we ever break that promise, it's a bug and we'll fix it.
