The construction cost calculator for professional building budgets.
Don't start from zero: build your estimate from real, settled reference
projects — or from your own completed budgets. €/m² by region, number of
units and building standard, broken down into DIN 276 cost groups, and
shared with everyone involved.

For international readers
Built for building in Germany.
The calculator estimates construction costs for projects in Germany, using
German reference data and the German cost standard. If DIN 276 is new to
you, our guide to DIN 276
explains the eight cost groups in English, with mappings to Uniformat,
MasterFormat and ICMS. The application interface and the intake form are
currently in German.
One calculator, two uses
A tool for professionals. An estimate for owners.
The same calculator, the same data — two ways in.
The tool
Develop building budgets — for developers, contractors and architects
The DIN 276 budget of an earlier project becomes the calculation for the
next one: adjust benchmarks, add cost lines, compare variants. Share the
finished budget with the owner, the bank and your partners — who read it
in the same format and can respond with scenarios of their own.
What will your apartment building cost? — for owners
Planning an apartment building in Germany? In a few minutes you get a free
cost estimate based on real reference projects — by region, number of units
and building standard, as a complete DIN 276 cost structure you can save and
keep working on. More than 5,000 owners and planners have already run over
6,000 free estimates.
From a reference budget to a budget you can share.
Every calculation starts with a real project — and ends in a document everyone involved can work with.
01Reference
Start from a real budget
A real, settled reference project as your starting point — from a four-unit terraced house to 30+ apartments. Or one of your own earlier projects as the template.
→ Reference projects included · your own reference models with an organization
02Budget
Develop the budget
Region (postal code), number of units, areas, standard, construction start — every change recalculates immediately. Add, split and rename cost lines; run variants side by side.
→ Regional factor and construction price index applied automatically
03Share
Share & export
Everyone involved sees the budget in the same format and can reply with their own scenarios — sharing is free. For the bank and the owner: PDF export with your logo.
→ A bankable DIN 276 document, not a consumer ballpark
Built for professionals
The breakdown no consumer calculator gives you.
Project managers, developers and architecture back-offices don't need a ballpark figure. They need a cost structure that survives scrutiny.
DIN 276 output
Cost groups 100–700 in full — the structure German banks, owners and specialist planners calculate in. Our DIN 276 guide explains what each number means, in English.
Real reference projects
Benchmarks from settled construction projects — not from catalog tables. And with an organization: your own projects as references.
Current construction price index
Regional factor by postal code and price development up to the planned construction start — the calculation reflects today, not last year.
PDF export
A cleanly typeset calculation as a PDF — ready for the bank, the owner, or an acquisition decision.
Co-branding & white label
Your logo on every document — and, if you want it, the calculator on your own website under your own brand.
Part of the BlitzFin platform
The estimate becomes the budget, the budget becomes live construction cost controlling — and completed projects become the reference for the next calculation. One platform.
Pricing
Calculating is free. You pay for depth.
The standard calculation is free — in full DIN 276 depth, with unlimited saving. You only pay for what makes the calculation yours: your own structure, your own references, PDF export. Without a subscription as a 30-day pass — or as an annual membership for the whole organization.
Free
The standard calculation — not a trial
€0permanently, no time limit
Complete DIN 276 structure with reference benchmarks
Not a trialFree means free
The free standard calculation does not expire. Your models stay saved and readable — even after a pass ends. A calculation never expires, only full access does.
No subscription on the passes
A pass is a one-off purchase: 30 days of full access, then it ends by itself. Nothing renews, nothing needs canceling.
Why an introductory price?
Not every feature we want is in yet — so it is considerably cheaper than it will be later. We build according to what users need.

Building types
One calculator, one methodology — per building type.
Each building type gets its own reference projects and benchmarks. The apartment building comes first.
Residential
Apartment building
From a four-unit terraced house to 30+ apartments with underground parking — construction costs by region, number of units and standard.
Production and logistics halls: construction costs per m² by construction method, span and fit-out standard.
Commercial · in preparation
Office buildings
Construction costs for office buildings per m² of gross floor area — by standard, level of building services and region.
Data basis
Reference projects and the construction price index in professional
collaboration with Stadtblick Architekten. Every reference project was
really planned and really settled — the benchmarks come from the building
site, not from a table.
In the calculator in a minute. With a real project.
