Estimate your monthly mortgage repayments

Use Kandoo's mortgage calculator to estimate how much your monthly mortgage repayments could be based on the property price, deposit, interest rate and mortgage term. It can help you understand how changing your deposit, loan amount or repayment period may affect the amount you pay each month.

How to use the mortgage calculator

Enter the price of the property you are looking to buy, the amount you plan to put down as a deposit, the interest rate you want to calculate against and the length of the mortgage term. The calculator will estimate your monthly repayment, total amount repayable and the amount of interest you may pay over the full term.

What affects your monthly mortgage repayments?

Your monthly mortgage repayment is mainly affected by the size of your mortgage, the interest rate and the term of the loan. A larger deposit usually means borrowing less, which can reduce your monthly repayments. A longer mortgage term can also reduce the monthly payment, although it may increase the total interest paid over time.

Mortgage amount and deposit

The mortgage amount is the property price minus your deposit. For example, if you buy a property for £250,000 and have a £25,000 deposit, the mortgage amount would be £225,000. Lenders will usually consider your income, credit history, affordability and deposit size when deciding how much they may be willing to lend.

Interest rates and mortgage terms

The interest rate has a significant impact on the total cost of a mortgage. Even a small change in the rate can make a noticeable difference to monthly repayments. The mortgage term also matters: shorter terms usually mean higher monthly repayments but less interest overall, while longer terms usually mean lower monthly repayments but more interest over the life of the mortgage.

Is this mortgage calculator accurate?

This calculator is designed to provide a useful estimate, not a guaranteed mortgage quote. It does not include arrangement fees, valuation fees, insurance, taxes, early repayment charges or lender-specific affordability checks. The actual amount you can borrow and repay will depend on your personal circumstances and the mortgage products available at the time you apply.

Compare mortgage options before applying

Before applying for a mortgage, it is worth comparing different rates, terms and deposit levels to understand what may be affordable. Kandoo is a credit broker, not a lender, and can help customers explore finance options from relevant providers.

How much deposit do I need for a mortgage?

Deposit requirements vary by lender and mortgage product. A larger deposit can reduce the amount you need to borrow and may improve the range of mortgage options available to you.

Does a longer mortgage term reduce repayments?

A longer mortgage term usually reduces the monthly repayment because the loan is spread over more months. However, it can also mean paying more total interest across the full mortgage term.

Can this calculator tell me how much I can borrow?

This calculator estimates repayments rather than affordability. How much you can borrow depends on your income, outgoings, credit profile, deposit and the lender's affordability checks.
