Property Calculator

Analyse buy-to-let, BRRR, and HMO deals: yield, cashflow, SDLT, cash-on-cash return and stress tests. Save, export, and import deals. No login required.

Educational tool only. Figures are estimates based on the inputs you provide. This calculator is not financial, mortgage, tax, investment or legal advice. SDLT/LTT and lending rules can change, and your situation may differ. Always speak to a qualified broker, accountant and solicitor before making any financial or property investment decision.

Traditional buy-to-let deal analysis focused on yield and cashflow.
