Property & Mortgage

15 calculators
Mortgage, stamp duty and property calculators for buyers, movers and landlords across the UK.

Understand the true cost of your home

A mortgage is the biggest financial commitment most people ever make, and small changes to the rate, term or deposit can mean tens of thousands of pounds over its lifetime. Our property and mortgage calculators help you compare the options clearly before you talk to a lender or broker.

Begin with the Mortgage Calculator and Mortgage Repayment Calculator to see monthly payments for any loan amount, rate and term. Not sure what a lender will offer? The How Much Can I Borrow Calculator and Mortgage Affordability Calculator estimate your borrowing power from income and outgoings.

Pay less interest and invest smarter

Already on the ladder? The Mortgage Overpayment Calculator shows how overpaying shortens your term and slashes total interest, while the Remortgage Calculator helps you decide whether switching deals is worth it. Keep an eye on your Loan-to-Value ratio to unlock better rates.

Landlords and investors can weigh up returns with the Buy-to-Let Mortgage Calculator and Rental Yield Calculator, while the Equity Release Calculator and Bridging Loan Calculator cover later-life and short-term borrowing. Every calculator is free and updated for current UK rates.
