Put numbers to your next decision.
Explore what a mortgage could cost, estimate a purchase budget and plan buying or selling costs. Four free calculators, with the assumptions explained.
Calculator 01
Stamp Duty calculator
Work out your exact Stamp Duty Land Tax bill in seconds - standard rates, first-time buyer relief and the additional-property surcharge. Rates sourced from GOV.UK.
Open tool
Calculator 02
Mortgage affordability calculator
Estimate how much you could borrow based on your household income. The result is indicative - lenders set their own affordability criteria, so the amount offered can be higher or lower.
Open tool
Calculator 03
Mortgage repayment calculator
Work out your monthly repayment, total interest and the full amount you will repay on a capital-and-interest mortgage. Illustration only - your actual rate depends on your lender, deposit and credit history.
Open tool
Calculator 04
Buying and selling cost calculator
Estimate the full cost of moving home in one place: Stamp Duty (exact), plus market ranges for estate agent fees, conveyancing, surveys, EPC and removals. Use the lower-to-upper span as your working budget, not the mid-point.
