A smoothly running assembly process with a low failure rate also depends on whether all parts fit. The specifications with regard to accuracy must be met too. In addition, a low cost is important to have competitive strength. To achieve all this, a good tolerance analysis is essential.

TolStackUp is a professional Excel tolerance analysis template. Save time and get started quickly with a flawless analysis.


TolStackUp is a tolerance analysis spreadsheet (template) created in Microsoft Excel. It is designed to analyze and manage the impact of dimensional deviations of parts in an assembly.

It is common to perform such tolerance analyses in a spreadsheet, usually Excel. A lot of work is required to create spreadsheets that meet all the requirements for these analyses. TolStackUp has everything you need to analyze and manage the dimensions and tolerances of parts in an assembly. Including correct calculation of the statistical results. The structured and methodical design makes the analysis and management clear and transparent.

By using a so-called ‘tolerance pool‘, TolStackUp is suitable for the analysis and management of large, complex assemblies with many tolerance chains. But it is also ideally suited for simple assemblies with only a single tolerance chain.
