They run the same engine as the product
Each calculator here computes with the same code that underwrites a real deal inside DealWise AI, not a separate script written for a marketing page. A cap rate worked out here and a cap rate worked out on a live deal come from one implementation, so they cannot drift apart.
That matters more than it sounds. Standalone calculators are exactly where a product ends up quietly contradicting itself: one page rounds differently, another amortizes annually instead of monthly, and nobody notices until a customer asks why two screens disagree.
Learn the underwriting behind them
A calculator answers one question. Underwriting answers the deal.
DealWise AI derives NOI from your actual rent roll, projects cash flow across the hold, and ends with a clear buy, hold or pass. Free to start.
