The fee schedule for architects and engineers (HOAI) has always been a central component for calculating project costs in the construction and planning sector. But in an age of digital transformation, traditional, manual calculation methods are increasingly reaching their limits — especially for C-level managers, engineers and architects who want to make processes efficient and transparent. In this article, we will show you how a modern, digital HOAI computer not only revolutionizes cost calculation, but also offers decisive competitive advantages.
Challenges of traditional HOAI calculations
Many companies still work with spreadsheets or separate software solutions, which are often not interconnected. These results in:
🛠️ Lack of integration: Data is transferred manually, which is time-consuming and prone to errors.
📉 Non-transparent calculation: Incomplete or outdated data make precise project analyses difficult.
⏳ High administrative effort: Manual entry and post-calculation costs valuable resources, which should be better invested in innovation and growth strategies.
High compliance and accuracy requirements
Especially in large architecture firms and Engineering CompanyWho manages complex projects, compliance with the HOAI legal requirements is essential. Imprecise calculations can lead to legal uncertainties and financial losses.
External HOAI Computers: More than just a digital tool
While the integration of a digital HOAI computer into existing systems offers enormous advantages, it is also worthwhile to use external, Web-based HOAI calculator to look at in more detail. Even without complex system integration, these specialized online tools offer immense advantages over manual calculation:
Time and cost savings
An external HOAI computer automates complex calculations in seconds. This not only reduces manual effort, but also minimizes potential sources of error.
- Quick results: Complex projects can be calculated in real time — without lengthy searches in tables or formulas.
- Cost efficiency: Errors in manual calculations can lead to expensive recalculations and disputes. Automated processes drastically reduce these risks.
Transparency and traceability
External computers often provide detailed reports and graphics that transparently display all calculation parameters and calculation methods.
- documentation: All inputs and calculations are comprehensibly documented, which not only increases planning security internally, but also creates trust externally during customer meetings.
- Benchmarking: Comparable projects can be quickly analyzed so that you always know whether your calculations are in line with the market.
Independence and flexibility
With an external HOAI computer, you are not bound to proprietary systems. These tools are usually platform-independent and can be used from any Internet-enabled device — ideal for mobile working and flexible office environments.
- Easy to use: Intuitive user interfaces also enable rapid familiarization without in-depth IT knowledge.
- Timeliness: External providers regularly update their computers to meet legal changes and market requirements.
Digital HOAI Computer — A Game Changer for Engineers & Architects
A modern HOAI computer not only offers automated calculation, but also integrates seamlessly into existing project management and ERP systems. The result is a central, digital platform that:
- Increases efficiency: Time-intensive manual processes are being replaced by automated workflows.
- Transparency creates: All relevant project data is updated in real time and can be accessed at any time.
- Data security ensures: GDPR-compliant solutions guarantee that all data is stored securely and centrally.
Improve ROI and competitiveness
It is crucial for managers to clearly justify investments. A digital HOAI computer enables:
- Cost transparency: Accurate and comprehensible calculations provide a solid basis for business decisions.
- Planning security: By integrating them into digital workflows, resources and budgets can be optimally planned.
- Sustainable optimization: Data-based analyses help to continuously optimize projects and minimize administrative costs.
Conclusion
Implementing a digital HOAI computer — whether as an external tool or as an integrative solution in your IT landscape — is an essential step towards remaining competitive in today's, digitalized world. Invest in digital tools that help you overcome the challenges of HOAI calculation — and set new standards in project and cost planning. Test a digital HOAI computer now and see how your work processes can be sustainably optimized.

FAQs
What is a HOAI calculator and what is it used for?
A HOAI calculator is a digital tool for calculating fees for architects and engineers. It is based on the fee schedule for architects and engineers (HOAI). The calculator is used for price calculations, contract checks and as an orientation aid in fee negotiations.
Which parameters are required for the calculation?
The most important parameters are eligible costs Work phases and fee zone. In addition, the fee rate, any surcharges, additional costs and value added tax are included in the calculation. Together, these factors determine the total fee.
Is there a charge for using a HOAI computer?
Many HOAI Calculators, such as For example, this, can be used free of charge. The free versions often also offer additional features such as printing and saving. However, some specialized or advanced versions may be chargeable.
Which version of the HOAI is currently valid and is it mandatory?
The currently valid version is HOAI 2021. According to Section 3 (2) HOAI 2013, it is generally necessary for the proper fulfilment of an order. However, since an ECJ decision in 2019, there has been more flexibility in pricing.
