How to make an animation of the total amount of the calculator in JS?

Question

JavaScript

Hello. I will say right away that my knowledge of JS is weak, so I need your help. I am writing a cost calculator and everything seems to be working, but do you want to create an animation of the total amount? as in ucalc. I connected the animateNumber library and jQuery, but I don’t know how to make everything work.
PS When increasing the value from the number field, the calculation does not always work.
