How much can I borrow?

How to use the how much can I borrow calculator

Our how much can I borrow calculator is easy to use. Simply:

  • Add your annual salary. And if you’re applying with a partner, add their salary too.
  • Click calculate and you’ll instantly see how much you may be able to borrow on a mortgage.

However, while this gives you an estimate, the exact amount a lender will lend you will depend on other factors like your outgoings. So your next step should be to speak to a mortgage broker for tailored advice.

What factors affect how much I can borrow?

Lenders consider a range of factors when deciding how much you can borrow on a mortgage, including:

  • Income. Lenders will usually lend up to 5 times your income. Although some will lend more.
  • Outgoings: Household spending such as on bills, loan repayments and childcare costs will be taken into account when assessing your mortgage affordability.
  • Credit score: You may be offered less if you have a history of bad credit.
  • Deposit size: The larger your deposit, the more you may be able to borrow on a mortgage.
  • Any debts: Lenders will also consider your debt-to-income ratio, which is your monthly debt repayments (mortgage, loans, credit cards etc) compared to your salary. 

Can I borrow more than the calculator says?

You may be able to borrow more than the calculator suggests, depending on your circumstances.

So it’s a good idea to get fee-free advice from the expert advisers at Mortgage Advice Bureau based on your individual circumstances.

Does the amount you can borrow vary by lender?

Yes. Each lender has different lending criteria so there could be a wide variation in what different lenders will let you borrow on a mortgage.

Getting expert advice is key because a mortgage broker will know how much different lenders may lend you and find the best mortgage for you.

How much will my mortgage cost?

The cost of your mortgage depends on how much you’re borrowing, your mortgage term, the rate of interest you’re paying and whether it’s a repayment or interest-only mortgage.

How do I compare mortgage deals?

The best way to compare mortgage deals is to look at the annual cost because this takes into account the mortgage rate plus any fees you’ll need to pay.

This means you’ll see whether you’ll save money overall by taking out a mortgage with a lower rate and higher fees or vice versa.

This is calculated by:

  • Adding up all the mortgage fees and deduct any cash back to find total fees
  • Dividing the total fees by the number of months the initial period to find the total fees per month
  • Adding the total fees per month to your monthly mortgage payment and multiply by 12 to calculate the annual cost

But you don’t need to do this yourself. The award-winning expert advisers at Mortgage Advice Bureau will crunch the numbers for you to find the right mortgage for you.

How do I find the best mortgage rate?

The best mortgage rate for you will depend on your personal circumstances. But you don’t need to do the legwork yourself – let the expert advisers at Mortgage Advice Bureau do the hard work for you. They’ll search over 100 lenders to find the right mortgage for you.

Does a mortgage in principle guarantee a mortgage?

No, a mortgage in principle does not guarantee that your application for a mortgage will be accepted. Nor does it make any guarantees about the amount that you can borrow.

That’s because the initial checks are limited and the lender doesn’t have a full view of your financial situation.

When should I apply for a mortgage?

You make your mortgage application when your offer is accepted on a house.

Frequently Asked Questions

How many times your salary can you borrow for a mortgage?

Lenders typically will lend up to 5 times your annual salary depending on your outgoings and credit history. But some lenders will lend more. For more information read our guide, What percentage of income should go to your mortgage?

How is mortgage affordability calculated?

A mortgage lender will look at your income and outgoings to make sure you can afford the monthly repayments. Lenders also assess if you will be able to keep up payments should circumstances change such as losing your job or if mortgage rates rise. For more advice, see How to get a mortgage in 6 easy steps.

How much can a self-employed person borrow?

The same salary multiple of up to 5 times annual income applies but if you’re self-employed, it can be more of a challenge to get a mortgage because you’ll need to prove you have a reliable income. Mortgage lenders usually require proof of your income for the last two tax years.

What is a Mortgage Agreement in Principle?

A mortgage in principle, also known as an ‘agreement in principle’ (AIP), ‘decision in principle’ or ‘mortgage agreement in principle’, is an indication that a lender could lend you a specified amount, based on details you’ve provided about your income, spending and debts. Many estate agents will ask if you have a Mortgage in Principle before you start the home buying process.

How does the mortgage term affect my repayments?

The longer the mortgage term you choose, the cheaper your monthly payments will be, when you take out a repayment mortgage. But you’ll pay more interest 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.
