Property calculators that work backwards.

Most property calculators start with the purchase price.

House Maths lets you start with the outcome you need - like your total budget including Stamp Duty, or the rental yield you want to achieve and work backwards from there.

Why work backwards?

Property decisions often start with a constraint or target, rather than a purchase price.

You might know the maximum you want to pay including stamp duty or the rental yield an investment needs to produce.

House Maths takes those numbers and works backwards to give you the figure you actually need.

Simple inputs. Clear calculations. No unnecessary complexity.
