Mortgage Repayment Calculator

How much will my mortgage cost?

The cost of your mortgage depends on several factors, including how much you’re borrowing, your mortgage term, and the rate of interest you’re paying. If your mortgage is a repayment mortgage you’ll make monthly mortgage repayments which cover both the capital you borrowed and the interest due. If it’s interest only you’ll just be paying the interest rather than reducing the amount you owe. You can find out more about this in our repayment vs interest only guide and use our interest only mortgage repayment calculator to find out how much you can expect to pay.

On a repayment mortgage the longer the mortgage term you choose the cheaper your monthly payments will be, but you’ll end up paying back more overall. If you choose a shorter term, your monthly payments might be higher, but you’ll reduce the total amount of interest you need to pay back, as you’ll be paying off the loan more quickly.

If you’re not sure which mortgage deal is likely to be most cost-effective for you based on your individual circumstances, our expert advisers can run you through the available options to make sure you’re getting the best deal possible.

Calculating mortgage payments

Once you’ve got an idea of how you’d like to repay your mortgage and how much you can borrow you can get started and calculate mortgage repayments based on the amount you need. To work out exactly how much you’ll pay every month, you’ll need to know how much you want to borrow, over how many years, and what interest rate you’ll be paying.

You can then enter these figures into our mortgage repayment calculator, then it’ll crunch the numbers and tell you how much your mortgage repayments might be every month, as well as the total amount you’ll pay over the term. You’ll also see exactly how much interest you’ll pay overall, and when you use our mortgage repayment calculator, overpayments can also be added to see how this can help bring the total amount you’ll pay down.

Remember that you’re unlikely to pay the same interest rate throughout your mortgage term though, as most deals only last for a few years. If you don’t remortgage to another deal after your initial deal ends, you’ll default to your lender’s standard variable rate which is likely to result in higher monthly payments.

How much interest will I pay on my mortgage?

The exact amount of interest you’ll pay depends on the mortgage rate you’re on. This can change over time. For example, you might be on a low mortgage rate at the moment, but if interest rates rise during this period, you could end up paying a higher mortgage interest rate when you come to remortgage, or if you move onto your lender’s standard variable rate.

This mortgage calculator shows you how much you would pay each month and over your mortgage term, assuming the rate remains the same. If your mortgage rate changes, you can use the calculator again to show what your payments would be on your new rate, as well as the change to the total amount over the term.

Other Mortgage Fees

When choosing a mortgage, it’s important to consider any additional fees and charges you might have to pay.

Lenders usually charge two types of mortgage fee: an arrangement fee and a booking fee. The booking fee is a non-refundable charge paid on application that allows you to reserve the mortgage you want.

The arrangement fee is, as the name suggests, a fee charged by a lender to set up the mortgage on your behalf. It’s charged when your mortgage completes.

Often the mortgage deals with the lowest rates carry the biggest fees, so it’s important to factor these in when trying to work out the best deal for you. If you’re taking out a relatively small mortgage, for example, it may be cheaper to choose a deal with a slightly higher interest rate but lower fees. If, however, you’re taking out a larger mortgage, it might be more cost-effective to take out a mortgage with a lower rate.

You’ll also need to factor in the valuation fee, charged by lenders for commissioning a mortgage valuation, which is a basic inspection of your property, as well as the cost of a more detailed survey if needed.

It’s also worth bearing in mind that if you do take a fixed or discounted rate then often these will come with Early Repayment Charges, which mean that if you want to repay your mortgage before the deal is up you could incur a large fee. You can use our mortgage early repayment calculator to see the impact of paying your mortgage back before the end of your term.

Remember, too, that you’ll need to set aside money for Stamp Duty, if you’re buying a property over £125,000, as well as the Land Registry fee to transfer the property into your name. Finally, you’ll also pay for conveyancing, the legal process of transferring a property from one owner to another.

Although these aren’t really mortgage fees, it’s a good idea to be aware of the things you’ll have to pay for after completion.

Unless you do it all yourself, there will be removal costs for hiring a moving company to bring all of your stuff from your old place to your new home. And if you’re buying your first home, or are moving into a significantly larger property, you’ll need to kit out your home with furniture.

Depending on the type of property you’ve moved into, you may also have to pay ground rent and service charge, as well as insurance. You should bear all of these costs in mind when working out how much your new property will cost.
