How does it work?

Simply enter your details and the calculator will do the maths for you in just a matter of seconds. You’ll need to input your:

  • Annual income 
  • Monthly take-home amount
  • Any other income you earn
  • Monthly household costs
    • Credit card loans & payments
    • Child & spousal maintenance
    • Any fixed costs e.g. school fees
  • Estimated living costs
    • Entertainment & leisure
    • Holidays
    • Food & groceries

Once you’ve put in all the necessary details, you’ll be able to find out how much you can afford to borrow. If you don’t have any expenses to put in certain sections, imagine what they’re likely to be in your new home. 

If applying with someone else, add their expenditure and earnings to yours. 

How accurate is it?

It’s important to remember that the calculator generates estimates based on certain assumptions. It gives you a general indication, not a 100% accurate figure.

However, it can still give you a useful understanding of where you are and how your monthly budget adds up. 

When it comes to buying a house, the more you know, the better! 

What mortgage can I afford?

When you apply for a mortgage, the lender will need to assess risk (when it comes to both you and the property). This means looking at:

  • Your income/salary
  • Property value
  • Any existing debts
  • Proof of employment
  • Your credit history
  • Incomings/outgoings

How much you can afford to borrow for your new house will depend on what they find during their assessment and the valuation survey.

How to improve your chances of getting a mortgage

Of course, getting an understanding of your mortgage loan affordability isn’t all you need. You need to consider the lender’s position and whether you’re a good candidate for a loan. 

Remember, if your mortgage is declined, your dream home isn’t out of your grasp. One lender’s opinion doesn’t apply to everyone.
