Can i put a code that give quote automatically?

hello, my site is a contractor site, i just was wondering if i cuold put something that gives estimated quotes. im gonna use an example let say you want to paint your room and you know that the room is 1200 sqft (for an example), so you put in the options interior paint and 1200 sqft then click on enter and gives you the estimated price of the quote. can i do this on squarespace?

I would probably look at building the calculator or form on an external service (like google forms/sheets) and then embed it on your site using an embed block or code block. usually the external service will give a way of embedding it.

If you don't want to try google forms/sheets, then there are dedicated services for this, a quick search on google shows one like https://calquo.com/ which has a free plan and squarespace instructions. Not endorsing that one, never used it, just showing that they do exist. (I know how to code so I would probably just write my own!). There's loads of others, free and paid. calculo.com convertcalculator.co etc. have a look at some of those. I've seen some one in the forum use https://grid.is/ too. I'm sure there's tonnes of options.

if you don't know how to code, then this is the best way.
