Is it possible to pre-define prices on the form? So if the collective figure appeared?

let's say there will be 3 people attending the event. The price of these double rooms or single rooms is certain. they can choose them.

I would like the total fee to be generated at the bottom as I select the person filling out the form.

I would appreciate if you help.

Yes, our forms support custom calculations. You can also assign calculation values to some fields option, so if a user selects one option, respective price is included in calculations. Please take a look through related help guides I'm linking below:
