Open toolHow to use them
Assumptions in, arithmetic out
Every tool here works from figures you supply. None of them quotes a market interest rate, a typical rent or an expected rate of growth, because no calculator can know those for a specific property in a specific building. What they do well is make the consequences of your own assumptions visible, and make two options comparable on the same basis.
The most useful habit is to run each tool more than once: a rate a point higher, a rent a hundred euro lower, a year of ownership shorter. If a decision only works under the most favourable set of inputs, that is worth knowing before you make it.
Where a figure on the platform is calculated rather than entered by you, it comes from verified listings published on Imperium and is labelled as such. Nothing on these pages is an index, a forecast or an opaque score.
Not financial advice
These calculators are informational. They are not lending offers, valuations, tax guidance or investment advice. Before committing to a purchase, mortgage or letting, take advice from a bank, a licensed valuer, a lawyer and a tax adviser as appropriate.
