Setpointanalysis tools for professionals

Tools that end in a document you can hand to someone.

Two calculators for decisions that cost real money. Both run entirely in your browser, both produce a PDF you can put in front of a client or a seller, and neither of them sends your numbers anywhere.

How they work

Both tools are a single web page. The numbers you type are computed in your browser and are never transmitted to us — there is no server that could receive them.

The analysis is free and always will be. Paying unlocks the PDF: the memorandum, the calculation behind it, and the questions worth asking before you commit. A licence key arrives by email on purchase.

If a tool does not do what this page says it does, write to [email protected] within 30 days and we refund you in full, without asking why.

Two teardowns a week

We take a live listing, run it through Ledgerline, and publish what we would actually pay and why. No sponsored listings, no broker relationships.
