Success across the board

4cost’s costing software and services are used successfully by private companies and in the public sector around the world. Our goal is to develop a global calculation standard that enables all industrial companies, regardless of industry and technology, to maximise transparency and cost control.

Our clients report on their successes with 4cost.

newboxes GmbH calculates costs with 4cost-aces

To provide its clients with comprehensive insights into their cost structures as quickly as possible, newboxes has implemented 4cost-aces as its costing software. It is used for the cost calculation of individual components as well as entire products. This includes, for example, hardware components such as converters, coolers and generators.


In order to create optimal framework conditions for the mass production of its air taxi “Prosperity I”, the R&D centre of AutoFlight Europe GmbH in Augsburg worked together with 4cost conducting a cost workshop. The aim was to obtain comprehensive cost transparency for different scenarios in a short time and with manageable effort.

MT Aerospace AG

MT Aerospace AG uses the innovative costing software 4cost-aces for the early cost determination of technical solutions in the aerospace sector. The parametric cost estimation enables the company to quickly evaluate different variants with regard to architecture and construction.


When it comes to determining costs at an early stage as well as identifying optimisation potential, the Engineering Services department at Liebherr-Werk Biberach GmbH has been relying on the innovative software solutions from 4cost since 2021. Martin Klotz, Product Cost Engineer at Liebherr, is a user of the 4cost costing software and reports on how the solutions from 4cost support him in his daily work.


The 4cost software solutions for the creation of valid cost estimates and consistent cost calculations from the early phase onwards are now in use in the Vehicle Systems Division, Business Unit Tactical Vehicles, of Rheinmetall AG. The Value Engineering department uses the 4cost software, for cost analyses and evaluations. With the aim of increasing sustainably and profitability of its products over the entire product life cycle.


The aim is to reduce product costs, the costing software from 4cost GmbH was introduced at MAN Diesel & Turbo, which makes costing more transparent and systematic throughout the entire product development cycle. When using the 4cost-suite, it is now possible to create valid cost estimates early stages of projects and continuously track the cost.


The companies 4cost and Liebherr are expanding their cooperation through a comprehensive agreement. The partnership between 4cost GmbH and individual business divisions of Liebherr companies has been existing since 2006. With the beginning of this year, the cooperation will be extended by a floating license model for the entire Liebherr holding. Both partners have on a long-term basis of trust which made it possible to develop and reach this solution.


Thanks to the close cooperation between 4cost GmbH and the digiZ | Digitalisierungszentrum Ostwürttemberg, companies in East Württemberg will now benefit and also have the opportunity to experience the advantages of parametric cost calculation. The software packages used by the digiZ are the 4cost-aces and 4cost-scenarioanalyser. Both tools enable users to make valid and quick cost estimates in early phases with only limited information available.


“Following an impressive and successful workshop, we decided in favour of 4cost’s software solutions for the Bremen location. The consistent calculation method of the 4cost tools convinced us right from the start. Very quickly we realised, that this methodology supports our needs in calculation, value engineering, purchasing and engineering excellently,” says Frank Hoffmann, Head of Supply Chain Management at Rheinmetall Electronics.


The 4cost GmbH has proven to be a valuable partner in several projects with its specially developed calculation tools for early cost estimation. A senior purchasing executive at Rolls-Royce concluded: “It is well known that the earlier cost transparency is established, the longer the leverage for cost optimisation. However, it is particularly challenging to establish good and reliable costs in the early stages of new projects. With 4cost’s modern parametric calculation models, however, it is possible to estimate good and valid costs already in phases with limited detail of knowledge.

AIRBUS Germany

The 4cost-aces calculation software is used in the area of “Costing” at Airbus Operations Germany. The main focus of using the application is the evaluation of aircraft systems. Especially in the early development phase. This shows that with 4cost-aces and the help of inbuild wizards, a fairly exact picture of a possible technical and industrial solution can be depicted.


The 4cost calculation software has been in use at Liebherr’s Kirchdorf site since 2008. “We decided on 4cost because we see a significant added value for our calculation and value analysis in a consistent approach from quick cost estimates to detailed calculations,” says technical director Werner Seifried.

HOLZER corporate group

Matthias Miesbeck, project engineer at the HOLZER corporate group, reports on his positive experience with 4cost: “The partnership-based cooperation with 4cost enables us to arrive at rapid cost estimates for our projects both in-house and directly at our customers site. In the past, for example, the costing software 4cost-aces was used as a parametric cost estimation model during development and production.


At the competence centre optoelectronics in Berlin, the services of 4cost GmbH have been used several times in recent years. Questions to be discussed were always what a new development would mean in terms of effort (time) and ultimately in terms of likely manufacturing costs for the company.

EADS Defence & Security

The costing software 4cost-aces is used as a parametric cost estimation tool at EADS Defence & Security in Ulm. In regular workshops costs are analysed with 4cost personnel and incorporated into quotations (proposals).

CI Tech Components

When it comes to supporting development projects consistently and cost-transparently from the very first idea, the company CI Tech Components relies on the use of 4cost software. “The convincing factors for the implementation of the 4cost solutions where the question is it possible to trace target costs from a value-analytical point of view and can it be achieved,” says project manager Jens Müller.

BARD Engineering GmbH

BARD Engineering GmbH uses 4cost’s software solutions in the area of strategic purchasing. This department is receiving all requested quotations from suppliers, assessing the quotations and the monetary review of the quotations. Equipped with the various modules of the 4cost software suite, the strategic purchasing department is methodically mastering the different requirements of daily business.
