Florida Home Seller Net Sheet Calculator | Framer custom code

A Florida real estate law firm needed an interactive tool on their website where home sellers could estimate their net proceeds from a property sale. The tool had to handle multiple variable inputs (sale price, mortgage balance, closing costs, taxes, commissions) and give sellers a clear breakdown of what they'd walk away with.

Beyond the calculation itself, the client wanted two key features: the ability for users to download a PDF copy of their results, and an option to email the breakdown to themselves for future reference.

I built the entire tool as a custom Framer code component using JavaScript and TypeScript, embedded directly into the firm's Framer-built website.

Dynamic calculation engine — The component takes user inputs (sale price, existing mortgage, estimated repairs, agent commission, title insurance, and other closing costs) and calculates net proceeds in real time as values change.

PDF export — Users can generate and download a formatted PDF summary of their net proceeds breakdown with one click, giving them a document they can share with their agent or keep for records.

Email delivery — An optional email flow lets users send the same summary directly to their inbox, handled through a backend integration.

Responsive Framer integration — The calculator sits natively within the firm's Framer site at nassehlaw.com, matching the existing design system and working across desktop and mobile viewports.

The calculator is live at nassehlaw.com/seller-net-sheet-florida, giving the firm's prospective clients a self-service tool that adds value before the first consultation even happens.
