What Salary Do I Need to Get a £100,000 Mortgage?

Need to borrow £100,000 in mortgage finance, but unclear what salary you need to demonstrate to qualify for your desired amount? Let's look at mortgage calculations and income multiples so you can apply with all the important information.

About your mortgage

Error: Yearly income income must be between £1 and £10,000,000.

Error: Regular bonus must be between £1 and £10,000,000.

Based on your yearly income, you may be able to borrow:


Most lenders will let you borrow 4.5 times your annual salary so, as long as you have a standard 10% deposit, you should be able to borrow this much.


Depending on your personal circumstances, some lenders may let you borrow 5 times your salary.


Lenders usually cap the amount they lend at 5.5 times your salary, so it’s unlikely you’ll be able to borrow more than this.

This calculator is an estimation of how much you could borrow. If you’re ready to take out a mortgage, speak to a Revolution brokers to see what options are available.

What Salary Do I Need to Get a £100,000 Mortgage?

If you're looking to buy a home and need a mortgage for £100,000, it can be complicated to work out what sort of salary you need to be eligible for this sort of lending.

Each lender has different criteria, and therefore it is essential to apply to the right place, rather than consult a mortgage provider whose criteria you don't meet. That can potentially rack up credit searches on your credit history that can make it even tougher to find approval elsewhere.

In this guide, we'll summarise how mortgage affordability works, and what sort of income you would need to demonstrate to qualify for a £100,000 mortgage.

How Do Mortgage Providers Use Your Income to Decide What They Can Lend?

Lenders need to be responsible for what they offer, so they need to know what you earn - and your partner if it is a joint application - to ensure you can afford the mortgage repayments.

This is called an affordability assessment and considers your outgoings as well as any other debts. Your debt to income ratio looks at how much you earn vs how much you owe.

Most lenders will offer an initial mortgage limit based on a multiple of your income, typically around three or four times, but sometimes as high as five or six times depending on the circumstances.

What Salary Do I Need to Qualify for a £100,000 Mortgage?

If we assume that a lender offers up to four times salary, you'd need to earn around £25,000 to qualify.

The below table shows a few income examples, and what the mortgage limit might be depending on what income multiple the lender can offer.


Lender A - 3 x Income

Lender B - 4 x Income

Lender C - 5 x Income

Lender D - 6 x Income































What are the Eligibility Criteria for a £100,000 Mortgage?

Lenders don't just look at how much you earn, but multiple factors in deciding whether they can lend and, if so, how much they can offer and at what interest rate:

  • Type of employment - permanent PAYE employment is the most stable form of income, so if you are self-employed, you will be assessed depending on how much trading experience you have backed up by filed accounts. If you are an agency worker, you might be asked for evidence of your experience and copies of any contracts. Lenders may also ask whether the role is temporary, short-term, fixed-term or permanent.
  • Deposit - the higher the deposit, the less risky the application and the more choices you will have. You can get a mortgage with a 5% deposit in some cases, but you are more likely to need around 10% or 15%, so a deposit of £10,000 or £15,000 on a £100,000 mortgage.
  • Credit score - lenders also need to check your credit history, and an adverse credit file will not work in your favour. Some lenders cannot accept applicants with bad credit, whereas others might need a larger deposit or might offer a less-competitive interest rate.
  • Age - again, this all depends on the lender. Some place an age cap on new applicants, or have a maximum age when the agreed term is due to end. Others have no age limits and specialise in later life mortgages.
  • The property - if you want to mortgage a buy to let, you will usually need a higher deposit and to prove what rental income the investment is expected to make. Second homes are also a little more complex, usually requiring a higher 25% deposit and stricter affordability checks.
