About This Calculator

The rent-versus-buy decision is one of the biggest financial choices most people make. This calculator compares your estimated monthly ownership cost (mortgage P&I) against a rental alternative, accounting for down payment and the opportunity cost of that capital.

Estimates only — not financial, tax, legal, or investment advice. Verify important results with a qualified professional before making decisions.

mortgage PMT = P × r / (1 − (1+r)^−N); down payment = price × %; monthly cost difference = mortgage − rent
