Mortgage calculator
Two questions, one tool. Work out the monthly repayment on a mortgage, or how much you could borrow on your income. Plus the bit most calculators skip: what your payment becomes if rates rise before you remortgage.

Fixed rates end. This is what the same loan costs monthly if you remortgage onto a higher rate, the risk most people forget to plan for.
Estimates only, not mortgage advice. Actual rates and what a lender will offer depend on the deal, your circumstances and the LTV. For a recommendation, speak to an FCA-authorised broker.

Most owner-occupiers take a repayment mortgage, where each payment chips away at the loan so it is gone by the end of the term. Interest-only, common for buy-to-let, keeps payments low but leaves the whole loan outstanding at the end, so you need a plan to repay it. This tool shows both.
The term is a trade-off
A longer term lowers the monthly payment but costs far more in total interest. A shorter term does the opposite. Nudge the years up and down to see the balance that fits your budget.
This is the borrowing side. For the money you need up front, use the cash needed calculator and the stamp duty calculator. Buying to let? Check it passes a lender with the BTL stress test, or ask the room in the free Housetrix Discord.
