Mortgage calculators

Using our mortgage calculators is a great first step. They’ll tell you roughly what you could borrow before you set out on your homebuying journey. So you don’t trip up before you’ve started. 

To work out what we're happy to lend, we'll look at your income, outgoings and any other money you owe. We’ll also ask about the deposit you could put down and your preferred mortgage term (how long you’d like to pay off your loan). 

After that, it depends what kind of mortgage deals are around. Do you want a fixed deal, where your interest rate stays the same for a set time, or a variable mortgage where rates could go up or down depending on the Bank of England base rate? If the rate changes, your monthly payments could change too. 

When you check out our deals, take a good look at the different rates. But first try out our mortgage affordability calculator to find out how much you could borrow. It’s a good way to calculate a mortgage without making a full application.  

This one depends on the size of your loan and your mortgage term. In other words, how much you’re borrowing and the length of time you want to pay the money back. 

Then there’s interest rates to think about. The higher your mortgage rate, the more interest you’ll pay back over time, and the higher your monthly payments could be.

Itching to discover the kind of numbers we’re talking about? Just try our mortgage rates comparison tool. This will give you the quickest ballpark monthly payments based on our latest deals.

With our change your mortgage calculator you can look at your current mortgage and new mortgage side by side. You can compare them and think about what’s best for you.

You’ll either pay a fixed interest rate, which stays the same for a set amount of time, or a variable rate that could change when the Bank of England base rate moves.

But here’s the really nerdy bit: we’ll work out the interest you owe daily. We’ll take your mortgage balance (that’s the total amount you owe), multiply it by your annual interest rate, and then divide it by 365 days. 

As you pay back your loan over time, the interest you pay actually goes down. That’s because we’ll be multiplying a lower and lower balance. 

The amount you’re borrowing and your rate, of course, are the most important things when you take out a mortgage. These decide how much you’ll ultimately pay in interest over your term.

So use our mortgage affordability calculator to find out how much you could borrow. And then check out our latest rates with our mortgage rates comparison tool. Without a mortgage calculator to help you, the maths are hard to work out on your own.

Loan to value (LTV) might sound baffling but it’s simpler than it might seem. It’s just how much you’ve borrowed compared to your home’s value.

So, say you paid £100,000 for your home. If you put down a deposit of £10,000 and borrowed the other £90,000, your LTV would be 90%. In other words, 90% of your home was paid for by your mortgage. 

Your LTV is important when banks figure out what mortgage to offer you. The higher your LTV, the higher the interest rate you could be offered. This is because the lender’s taking on more risk. 

The key thing, of course, is to work out how much deposit you want to put down. Our home deposit calculator can help you do this. 

Just add a few details including what type of home you want to buy, where it is, how much you’ve already saved, and the size of the deposit you’d like. Our clever calculator will tell you the deposit you’re likely to need and how long it’ll take to save for it.    

Thankfully not. Our mortgage calculators are just a handy guide. They’re not connected to credit reference agencies, and we don’t save or track what you enter. So, feel free to have a play and try different things. 

You can use our mortgage affordability calculator to work out how much you could borrow. If your mortgage is with us, you could try our additional borrowing calculator to see if you could borrow more. Your credit score won’t be affected. Not one bit.

By the way, if you’re worried about your finances, and want help to see what you’re spending , try our budget calculator. It can help you look at your outgoings and see where you might be able to cut back. This could make it easier to save for a deposit. So, it’s a good thing to try before you apply for a decision in principle

It's hard to say. Rates could go up or down depending on many factors, such as inflation and the economy's health.

If you’re worried about rates rising, it could make sense to choose a fixed rate mortgage. Then you’ll know what your monthly payments will be until your deal ends.

But if you reckon rates will go down, think about a variable mortgage instead. Your monthly payments will drop when the Bank of England base rate goes down. The flipside is your payments could go up if the base rate rises. 

You can check out our different types of mortgages to find out more. But whatever you decide, make sure you can afford what you borrow. Our mortgage affordability calculator can help you here.
