Built for UK property investors, landlords, developers, and businesses.
Make smarter property decisions with our practical property calculators and investment tools. Whether you are assessing mortgage payments for a new home, buy to let mortgage, stress testing rental income, or calculating stamp duty, these resources are designed to give you clear numbers you can trust before you commit.
Each calculator reflects commonly applied lender affordability models or current UK property tax rules, providing a practical starting point for investment planning. These calculators are designed to support early-stage scenario modelling and comparison, helping buyers and investors understand how changes to rates, deposits, rents or purchase prices may affect outcomes. Final lending and tax positions will always depend on individual circumstances and criteria at the time.
