Calculations in a PDF
When you are a student, banker, accountant or actuary, you spend much time on different calculations. The Add Fillable Fields feature allows you to insert different types of fields into your PDF or Word document and do complex calculations. Transform any document or form with smart digital fields using the drag and drop wizard.
To get started, upload the document to your pdfFiller account and open it in the Editor.
To create fillable fields for formula, click on the Add Fillable Fields tab on the right.
When the tab opens, you see different types of fields that you can add to your document. To add the Formula Field, select Formula.
Drag and drop the selected field anywhere on the document.
Open the Formula Builder at the top of your document. It will help you calculate a value based on number fields in the document.
Resize the field by dragging its corners or edges. Use the text formatting tools to preset the field’s text format including the font, size, color and alignment of text. Change the format of the calculated value by clicking Format on the right. Click the Save orange button in the top right corner to save the changes.
Once you’ve clicked Save, you will see the calculated value on the place where you’ve dragged and dropped the field.
To delete a fillable field, click on the trash can icon above it. You can customize any fillable field. Click Advanced in the right pane and select the options you need.
After you’ve added the Formula Field to your document, you can edit your document, sign or send it to be signed and share. When you’ve finished, click the Done orange button in the top right corner.
