I'm not a programmer, but I'd like to add an online estimate tool for a residential cleaning company. Customers would enter details such as square footage, number of bedrooms, bathrooms, and levels. The calculator would apply pricing multipliers that I define and then display an estimated price. What's the simplest way to build and add something like this? Could an AI coding tool generate the HTML and JavaScript for me, and what access would I need to place it on the website?

The calculator itself is probably the easy part. To add it to the company’s existing site, you’ll need permission and some way to edit the site, such as an embed block, custom HTML section, or access to the hosting account. If you don’t control the website, you can’t directly change its pages. You could instead create the calculator as a separate small web page and link to it or embed it if the site builder allows that.
Ask the person who manages the site what platform it uses and whether you can add custom HTML or an embed. Then have the AI tool create a single-page calculator with clearly defined pricing rules. If customers need to submit their contact details afterward, you’ll also need to decide where that information goes—email, a database, a customer-management system, or a booking form. That part may require more setup than the price calculation itself.
Yes, an AI coding tool can generate the basic calculator. It’s essentially a form plus JavaScript that reads the square footage, bedrooms, bathrooms, and levels, applies your formula, and displays the total. The important part is testing the results carefully and deciding whether the estimate should be a final price or just a starting quote.

Many website builders support an iframe or embed section, so a standalone calculator can often be placed on the existing page without changing the site’s main code.
