We have written a Detailed & Definitive Guide to Mortgage Affordability.

Here are some basics on what incomes are acceptable.

Gross Annual Income can include the following:

  • Salary
  • Commission
  • Bonus
  • Some employment allowances
  • Certain government benefits
  • Child maintenance
  • Self-employed income
  • Salary and Dividends for company Directors.


Commission and Bonus.

For commission and bonus, a large majority of mortgage lenders will use the average of the last 3 months. So the calculate add up the total of commission/bonus for the last 3 months, divide then times by 12. That gives you an annualised total based on an average of your last 3 months. Add that to your annual salary and enter into the calculator above.

Certain government benefits.

This might include tax credits, universal credit, child benefit or disability living allowance.

Self Employed and company directors.

One of the most common questions we get asked is – if I’m self-employed, how will lenders assess my income and affordability? So we have written a post about is How Mortgage Lenders Assess Self-Employed Income we give an overview of the different ways that lenders assess the income of the self-employed for the purpose of mortgage lending. Worth reading if you’re looking for a self-employed mortgage.

    I can't believe how helpful Thomas has been. So easy- Thomas did everything for me. He spent so much time on the phone talking through my situation and giving great advice, then found me an amazing deal. Highly recommended.
  • Avatar Jimmy Walshaw ★★★★★ 5 months ago
    Really pleased with Thomas’s help. I was struggling with finding the right deal to suit my needs when renewing and the advice he gave was really helpful. I now have a deal which suits me for the current period and is flexible enough to … More change. I have saved money each month and have a much clearer picture of my options once my current offer expires. Would 100% recommend and will be using him again.

    Genuinley can't speak highly enough about Thomas. To say he went over and above for us is an understatement.
    He was proactive, knowledgable and diligent throughout our house move and helped us enormously with his experience and
    … More his good humour.
    Honestly, let him sort your mortgage. There won't be a better option.

    We found Thomas through a recommendation and he has been professional and friendly throughout our remortgaging process, offering us sound financial advice along the way. We also didn't give him much time before our existing mortgage's … More fixed rate period was due to end, but he's managed to speed things up - we really appreciate this!

    Couldn't have asked for better advice and support to buy my first house and negotiate my recent remortgage. Trustworthy, honest and clear explanations through the whole process. Thank you Cai!

    Thomas at Hey Mortgages has now successfully brokered two mortgages for me and they were both arranged with a minimum of hassle.
