Project Summary
Materials · Labor · Equipment · Legal · Overhead · Profit · Taxes · Grand Total — all your values, all math.
Your inputs. Our math. Zero assumptions. ConstrCalc® is the professional platform for construction calculation, project planning, measurement conversion, and construction knowledge — used across 150+ countries.
After every calculation ConstrCalc® generates a rich post-computation Intelligence Panel — cost per unit, per floor, monthly / weekly / daily distribution, mix percentages, measurement conversions, and formula transparency. All from your numbers. Zero assumptions.
Materials · Labor · Equipment · Legal · Overhead · Profit · Taxes · Grand Total — all your values, all math.
Your cost is broken out per ft², per m², per yd², and per floor, using deterministic conversions applied only to the rates you entered.
The tool spreads your cost in a straight line across months, weeks, and days, based entirely on the duration you entered.
Percentage split across categories — visible bar breakdown, clear legend.
Your entered area in ft², m², yd² and across floors. Constants only, no rate change.
Every equation is printed inline where you compute, so you can see the math, verify it against your own figures, and trust the total it produces.
Contextual links to glossary, methodology, and guides — right where you compute.
PDF · Excel · Word · CSV · JSON · Print. Client-ready in one click.
Each tab is a discrete stage in your estimation pipeline, so you enter your values, watch the math resolve in front of you, and export the finished result.
Name, type, area, floors, duration, location multiplier, overhead %, profit %.
Permits, architect & engineer fees, surveys, insurance — by project type.
Standard quantities for cement, sand, steel, bricks, aggregate, paint — auto-calculated per your area. Or enter manually.
General & skilled labor with hourly or daily units. Total hours & daily equivalents computed.
Heavy machinery & small tools rental — unlimited entries, itemized by category.
Subtotal, overhead, profit, grand total, cost per ft²/m². Export in PDF · Excel · Word · JSON.
Open the full six-tab calculator in a new page. Your inputs auto-save to your browser.
Work in USD, EUR, GBP, INR, CNY, JPY, AED, NGN, and more than thirty other currencies, with the symbol updating live as you switch.
The interface speaks English, Español, Français, Deutsch, 中文, हिन्दी, العربية, and more, with full localization applied across every tab label.
Send a polished PDF to clients, hand Excel to accounting, drop the figures into Word for RFPs, or keep a JSON snapshot so you can resume editing later.
Every calculation uses only the numbers you enter, with no hidden multipliers and no invented figures working behind the scenes.
The interface is fully responsive, so the tabs collapse cleanly on phones and you can enter figures on-site directly from your own device.
Your work auto-saves to the browser, and you can upload a previous JSON file to continue editing or store an unlimited number of reports.
Work that used to take spreadsheets and two coffees now takes about fifteen minutes, thanks to six structured tabs that turn your input into instant totals.
Standard material quantities per 1000 ft² keep you from forgetting bricks, cement, or paint, while manual overrides let you set your own figures wherever you know better.
Because every line item is exportable, you can show your client the exact math behind the estimate rather than just a total, which builds trust and helps you win more work.
It works on any device with a browser, and there is nothing to install, no account to log into, and no lock-in of any kind.
Home builders, remodelers, custom homes, ADUs. Permit, materials, labor — all pre-configured for residential.
Office, retail, hospitality. Commercial-grade permits, ADA compliance, MEP engineering fees included.
Warehouses, factories, logistics hubs. OSHA, hazmat, environmental permits pre-listed.
Additions, retrofits, historic restoration. Structural assessments and asbestos inspections tracked.
Cost feasibility for early design. Present scenarios with different multipliers side-by-side.
You produce faster bids and protect better margins, with fewer omissions slipping through on the day you send the quote.
Cement, sand, steel, bricks, aggregate, paint — the standard quantities and how to adjust them.
Learn when to switch between hourly and daily units, how to compute equivalent daily rates, and how multi-worker crews break down across a schedule.
Residential, commercial, industrial, renovation — what to file, how much it typically costs, in what order.
No black-box multipliers. Every calculation ConstrCalc performs is published, documented, and inspectable in our Calculator Methodology.

The line items estimators forget — from soil tests to hazmat inspections — and how to catch them every time.
The difference between them, why they compound, and how to set percentages that keep you profitable.
Presenting to a client? Reconciling with accounting? Feeding a bid platform? Each export has a purpose.
Cut our bid prep from a day to under an hour. The tab structure matches how we actually estimate. And the PDF export goes straight to the client — no cleanup.
I show clients the formula transparency page and they stop questioning the numbers. That single feature is worth the switch from spreadsheets.
Multi-currency + 27 languages means my international clients get the exact estimate in their own terms. Nothing else on the market does this for free.
Glossary, cost guides, material guides, measurement guides, planning guides, methodologies, and country-specific practices — all inside the platform.
