Property Calculators

13 calculators covering affordability, deposits and running costs, each with its formula and worked examples.

Property Calculators brings together 13 calculators for affordability, deposits and running costs, including Cap Rate Calculator, Cash On Cash Return Calculator, Home Equity Calculator and LTV Ratio Calculator.

These are separate pages rather than one tool with a mode switch because the inputs differ, the interpretation differs, and the question behind each one is different. Each page opens with the formula it uses, defines every variable, and walks the calculation through real numbers before you type anything.

All 13 pages compute in your browser: nothing you type is sent anywhere, and results update as you edit. Each one carries worked examples, interpretation bands where a score needs context, and a FAQ answering what people actually ask about that calculation.

The collection is part of Money & Finance, and every page links to the neighbouring calculations you usually need next.
