The Story and the Target

Years of experience in costing on the sides of users and software-developers have brought us to think over and over again about the optimal solution for product cost calculation. The available software is complex and lacks flexibility. Our experience has shown, that calculations should be:

Adaptable and expandable at any time, but…

…secure through a system of rights and roles based on passwords…
…that integrates existing solutions, but…
…which is standardized and centrally controlled if needed,…
…easy to comprehend and understandable for third parties, in order to…
…exchange calculations internally and externally for discussion or even open book calculation, but without…
…excluding externals with different software,…
…underlined with consistent data from costing-experts (worldwide benchmark-data, production process calculators and so forth),…
…embedded in the existing software-landscape due to applicable interfaces,…
…accessible for every authorized person…
…withouth becoming dependent to the software in case the license runs out…
…and EVERYTHING without additional application complexity!

We asked ourselves, why existing solutions were cloned after Excel with reduced functionality with much higher complexity. So we combined the demands listed above with the costing-expertise from our everyday profession, with process logic, with data from cooperations, universities, public statistic authorities and realized a software, which, in fact, ist independent but directly and transparently integrated with Excel. The enormous feedback from partners that saw the software at work, brought us to professionalize the software in order to offer it to everybody at a low cost. CALC4XL enables you to discuss actual costs, not only about budgets. With CALC4XL it is in your power to calculate with certainty and confidence – independently for your department, across departments, throughout the whole company or even live with your partners, suppliers or customers.

Therefore it is important for us, that you become part of our costing-network and receive expertise and support for your projects. We offer workshops, accompanied project and cost calculations as well as mutiple contacts to other costing calculators.


CALC4XL is an independent software which is transparently integrated into Microsoft Excel as an Add-In.

As in the picture, you will receive a “CALC4XL”-Menü after installment through which you can use all the CALC4XL functions.

Thereby you will not have any additional IT-barriers (ready to use in 10 seconds) and, most importantly, no additional application complexity.

Show your calculations to colleagues or externals without a CALC4XL-license with free CALC4XL-Viewer. Your usual Excel-application therewith enables you an exchange beyond any boarders even to the possibility of an open book calculation.

Use, modify and expand the CALC4XL cost calculation templates and your own Excel templates with your Excel-know-how or simply embed a single cost module (worldwide data regarding salaries, machines, production process calculators, …) in your existing solution (see also below „The Integration“).

In case you want to end using CALC4XL at any time, you keep all of your data, calculations and your own templates in your usual Excel.
