How lenders really decide how much you can borrow
Mortgage lenders don’t just look at your salary and multiply it by a number. They take a wider view of your finances to check the mortgage is genuinely affordable for you.
They’ll usually look at:
- Your income (basic, bonuses, overtime, self-employed income)
- Your monthly outgoings
- Any existing credit commitments
- Your credit history
- The length of the mortgage term
- Current interest rates and stress testing
This is why two people on the same salary can be offered very different borrowing amounts.
The “salary multiple” myth
You might hear figures like “4.5 times your income” or “5 times salary”.
These can be a guide, but they’re not guaranteed.
For example:
- Someone earning £45,000 with minimal commitments may borrow more than
- Someone earning £55,000 with childcare costs, car finance and credit cards
It’s affordability that matters most, not just income.
Why online calculators can be misleading
Online mortgage calculators are useful for rough planning, but they don’t see:
- Your actual spending habits
- Your credit profile
- How different lenders assess risk
They also don’t tell you which lenders are most likely to say yes, which is often more important than the headline number.
