With CalcTape, even extensive calculations stay clear on your PC. The software makes the arithmetic visible – you create interim results and correct any number or operation afterwards. CalcTape replaces your old desktop calculator.

## Features

- Enter a long list of calculation items at once – and keep the overview, just like an adding machine with a paper tape.
- Change any item afterwards – the entire calculation updates automatically.
- Use interim results to structure and verify your calculation.
- Comment your items to give context and meaning to the calculation.
- Save calculations as files, reopen and edit them anytime – with automatic recalculation.
- Use files as templates for similar calculations and what-if scenarios.
- Preassigned tax keys you can adapt yourself – in every edition.
- Named values with parentheses and trigonometric functions, without a limit and without a surcharge.
- Pro version: any number of files side by side, your own keys and keyboards, adding machine mode, theme editing, Excel export, backup and commercial use.
