**EltonCris**Hi,

Are you using payment tools? Calculations are automatic on the payment tools, just enable the Total so you can see the total calculation on the form. Just click the payment field on your form and toggle the "Show Total" option on the top toolbar.

Or if you are using regular fields, you can use Form Calculation widget to get the total number of the selected fields. Form Calculation is under widgets.

We also have a complete guide about Form Calculation, https://www.jotform.com/help/259-How-to-perform-calculation-in-the-form

If you need further assistance, let us know here.

Regards!
