Accounting Calculator (Pro Only)

By Cynthia, 6 December, 2025

The Accounting Calculator tool in Foxit PDF Editor gives you an easy way to have efficient paperless workflows. When preparing some digital workpapers (such as expense reports) or if you are an accountant and tax preparer, you can not only do calculations with the tool, but also add the electronic calculator tapes to your PDFs as annotations, the same way you did on paper. 

  1. Open your PDF document in Foxit PDF Editor, and choose Comment > Accounting Calculator.
  2. The calculator window pops up. You can see the calculator keypad on the left, the calculator tape area on the right, and the related buttons on top of the window. The functionality of the calculator is very similar to most hand-held calculators.
  3. (Optional) Before doing your calculation, do the following settings with the buttons as needed:
  • Reset: reset the calculator to the default settings.
  • Undo/Redo: undo or redo your last action.
  • Date Time: specify whether to show the current date and time on the calculator tape.
  • Add Line/Del Line: click Add Line to insert a blank row above the currently selected row in the existing tape and then you can double-click the cells in the newly-added row to enter a value and choose an operator. Or click Delete Line to delete a row that you want to delete from the tape. As you insert or delete a row, the calculation result updates automatically.
  • Clear Tape: discard all the current calculations and then you can start a new one. 
  • Decimal: specify the number of displayed or rounded decimal places (i.e., the number of digits of the decimal part).
  • Rounding: specify the rounding method for the decimal part. For example, with the Decimal set to 2 above, the following table shows the different results of different rounding methods.

  1. (Optional) Double-click a cell in the Comment column in the tape to add a description for the calculated item. You can also double-click the cells in the Amount and Op columns to make changes as needed.
  2. When you complete the calculation, you can type the name for the tape in the textbox above the calculator tape area, and save the tape to the document by clicking the Create Tape button.   
  3. The digital calculator tape is added to the document as a Textbox comment. 
  4. (Optional) To modify the tape, right-click the tape in the document and choose Edit Calculator Tape from the context menu. Make necessary edits to the tape in the calculator window and click the Complete button when you finish. Select Yes in the pop-up dialog box if you want to update the creation time of the tape at the same time.
