A useful starting point, with context.

These resources are written or curated by me. Calculators use model assumptions and don’t establish what a buyer will pay. The transaction explorer links to public sources; selected deals may differ substantially from yours. Use the guides to prepare questions, then review the details of your business and any offer with your advisors.
