Your Debt to Income Ratio is %

Good news! Most mortgage lenders will class your debt-to-income ratio as low. You’re unlikely to be declined for a mortgage based on your outgoings, but speaking to a mortgage broker before applying is still recommended as they can improve your chances of getting the best deal.

Most mortgage lenders will class your debt-to-income ratio as moderate, which means some of them might view your application with caution. Some lenders are much more strict than others when it comes to affordability and debt, so it’s important for you to find a lender who’s more lenient. You should speak to a mortgage broker before you apply to ensure you’re matched with a lender whose criteria you fit.

Most mortgage lenders will class your debt-to-income ratio as high. But that’s where we can help! With so much of your monthly income going towards debt repayments, you could struggle to get approved for a mortgage without the help of a mortgage broker. We can help you find a lender who’s more lenient on debt and affordability, and could still secure a mortgage approval.

What is a mortgage calculator?

A mortgage calculator is a category of online tools that you would generally use for one of two purposes: working out monthly repayments or calculating your affordability.

There are standalone calculators on our site for mortgage affordability and mortgage repayments, but these aren’t the only ones available.

Other types of mortgage calculator include…

  • Buy-to-let mortgage calculators: For working out your affordability and repayments based on projected rental income.
  • Loan-to-value calculators: For working out your LTV ratio
  • Self-employed mortgage calculators: These show maximum borrowing for various types of self-employed traders, such as contractors, company directors and more.
  • Remortgage calculators: For working out what kind of remortgage deal you can get and how much equity you can potentially release, if you wish to.

You’ll also find calculators for specialist types of finance, including bridging loans, equity release and offset mortgages.

How do they work?

Each of our mortgage calculators works differently depending on which of these tools you’re using, but you’ll find easy-to-follow instructions built into the calculators themselves. Each one requires no more than a few personal details to crunch the numbers you need.

In terms how our two main calculators determine your results, our mortgage affordability calculator takes your salary and multiplies it by the three most common income multiples that mortgage lenders use to determine maximum borrowing: 4.5, 5 and 6, and displays results for each one so you can compare how much you could potentially borrow across the market.

Our mortgage repayments calculator takes your loan amount, interest rate and term length and works out how much you will pay each month based on these factors. It returns results for a capital repayment mortgage by default but you can change this to interest-only for comparison.

The other calculators you will find on our site work similarly, with any notable differences and specifics clearly explained in the copy within the tools themselves.

Why use a mortgage calculator?

They can be really useful as a starting point if you’re planning to apply for a mortgage, a remortgage or take out another type of finance that our calculators cover.

With a mortgage affordability calculator, you can get a rough idea of the maximum amount you could potentially borrow as well as the number of lenders you’ll have to choose from. For example, if you need to take out a mortgage worth more than 5 times your salary, you will know that your options might be limited to the kind of niche lenders you’d need a broker to find.

Knowing that your mortgage is affordable can also give you peace of mind and a clearer idea of what you need when the time comes to prepare your application.

Similarly, using a mortgage repayments calculator can give you a firm idea what your budget will be once you have your mortgage, as well as how that might vary depending on what interest rate you secure and term length you choose. Some borrowers might also find it useful to compare what their mortgage will look like on an interest-only agreement vs. a repayment one.

Are there any limitations you should know about?

The only limitations of a mortgage calculator is that they can only give you a rough idea of your mortgage repayments, affordability and other variables.

With mortgage repayments, for instance, you might be unsure what kind of interest rate you will qualify for or what term length your lender will agree to. Similarly, there’s no guarantee that you will qualify for the income multiple you need when undergoing an affordability assessment.

The numbers a mortgage calculator returns are not bespoke to you, but that doesn’t mean they are of no value at all. Using one of our calculators is a good starting point on your journey, but we always recommended taking professional advice after you’ve crunched your numbers.

Get bespoke calculations from a mortgage broker

The best way to get fully-accurate mortgage calculations that are bespoke to you is by using our matching service to be paired with your ideal mortgage broker.

Not only will they be able to provide you with personalised figures for your affordability and repayments, they can add context to these numbers by introducing you to the mortgage lender who is best placed to offer you the mortgage you need with the best possible rate.

FAQs

On a residential mortgage, the maximum amount would usually be 4.5 times your annual salary, although some lenders might stretch to 5 or 6 times your income.

The higher income multiples are typically reserved for borrowers with strong applications, which typically means a large deposit and stable income. Some lenders reserve their 6-times-salary mortgages for people in high-earning professions, such as doctors and lawyers.

This is usually based on the property’s projected rental income. To pass an affordability assessment for a buy-to-let mortgage, most lenders expected the forecast rental income to exceed the mortgage payments by 125% to 145%.
