The actual mortgage you obtain will depend on a number of factors that are specific to your own personal and financial circumstances.

What is a mortgage calculator?
Mortgage calculators are tools you can use to estimate how much you can borrow on a mortgage and other mortgage costs in different scenarios. There are mortgage calculators that estimate mortgage payments, and calculate how much mortgage repayments will increase or decrease if a mortgage rate changes. Others are designed to calculate how much interest you could save by overpaying on your mortgage, and how much faster you could pay off your mortgage as a result. A stamp duty calculator gives you an idea of the amount of stamp duty tax you’ll need to pay the government when buying a home.
Who is a mortgage calculator for?
A mortgage calculator may be used by anyone buying a property using a mortgage including:
- first-time buyers
- homeowners looking to remortgage
- home movers
- existing homeowners purchasing an additional property
- buy-to-let landlords
What information do I need to use a mortgage calculator?
Different mortgage calculators require you to share different information, but some of the details you’ll usually need to have an idea of include:
- your income
- The amount you want to borrow
- your current and potential new mortgage rates
- the mortgage term over which you’ll repay your mortgage
- the value of the property you’re buying

Do mortgage calculators involve credit checks?
Mortgage calculators don’t tend to include credit checks and none of ours do. Credit checks are only usually carried out by a mortgage lender once you’ve completed a full mortgage application.
What will my mortgage repayments be?
Your monthly mortgage repayments will depend on the size of your mortgage, your mortgage rate, and the period of time – or mortgage term – over which you intend to pay off your entire mortgage. You can use our mortgage repayment calculator to help you work out how much your mortgage payments may be.
How much mortgage can I afford to borrow?
How much you could borrow through a mortgage will depend on several factors. Each lender has its own criteria for calculating how much they may be willing to lend to you. Your income, outgoings, employment status, credit score and deposit all usually affect the mortgage you can afford. Our mortgage borrowing calculator can give you an idea of the mortgage you may be able to get.
How much deposit do I need for a house?
Typically you’ll need a minimum deposit of 5% of a property’s value to get a mortgage. Having a larger deposit usually gives you access to better mortgage rates and deals.

What types of mortgages can you get?
The main mortgage types you can get include:
- Fixed-rate mortgages: The interest rate on a fixed-rate mortgage stays the same for a certain number of years. This means that your mortgage repayments remain the same until the fixed-rate deal period ends.
- Tracker rate mortgages: The rate on a tracker mortgage is usually a set amount above the Bank of England base rate, and will automatically track any changes to the base rate. This means your repayments have the potential to rise and fall.
- Standard variable rate (SVR): When an initial rate period ends, such as that on a fixed-rate deal, most lenders will switch you onto their standard variable rate, or SVR, unless you remortgage to a new deal. SVRs are often higher than the rate available on other mortgages and lenders can change them when they want.
- Discount mortgages: With a discount mortgage, the rate you pay tracks a lender’s SVR but is discounted for a set period of time.
- Offset mortgages: An offset mortgage allows you to offset your savings against your mortgage to lower the amount of interest you need to pay.
- Interest-only mortgages: With an interest-only mortgage, monthly repayments are lower because you only pay your mortgage interest. However, this leaves the original mortgage amount to be paid back in full at the end of the mortgage term.
Can a mortgage calculator help to find the best mortgage deals?
Mortgage calculators can help you work out the amount of mortgage you can afford and how different mortgage rates may affect your repayments. However, to find a specific mortgage deal you’ll need to shop around. Speaking to a mortgage adviser is a good way to help you find the best deals for your financial circumstances, or you may be confident to do your own research.
