How accurate are your mortgage calculators?
Our calculators are professionally verified and follow industry standards. They provide accurate estimates based on current market conditions and standard calculation methods used by UK lenders.
Do I need to create an account to use the calculators?
No, all our calculators are completely free to use without registration. You can access all features immediately and use them as many times as you need.
Are the calculations updated for current UK regulations?

What is the average mortgage rate in the UK in October 2025?
As of October 2025, average UK mortgage rates vary by product type. Fixed-rate mortgages typically range from 4.5% to 6.5% depending on the loan-to-value ratio and term length. Variable rates may start lower but can fluctuate with Bank of England base rate changes. Use our Interest Rates Calculator to compare current rates and calculate payments.
How much deposit do I need for a first-time buyer mortgage?
First-time buyers typically need a minimum deposit of 5-10% of the property value. However, a larger deposit (15-20%) often secures better interest rates and lower monthly payments. Some government schemes like Shared Ownership may allow smaller deposits. Check your deposit requirements and explore options with our Deposit Calculator and First-Time Buyer Calculator.
Can I get a mortgage if I'm self-employed?
Yes, self-employed individuals can get mortgages, but lenders typically require 2-3 years of accounts or tax returns (SA302 forms) to verify income. Some specialist lenders may accept 1 year of accounts for established businesses. Self-employed applicants may face slightly higher rates or require larger deposits. Learn more in our comprehensive Self-Employed Mortgage Guide and use our Affordability Calculator to estimate your borrowing capacity.
What is the maximum income multiple for UK mortgages?
Most UK lenders offer 4-4.5 times your annual gross income as standard. High earners (typically £75,000+) may qualify for up to 5.5 times income with some lenders. Joint applications combine both incomes. Lenders also conduct affordability assessments considering your expenses, debts, and financial commitments. Calculate your maximum borrowing amount with our Affordability Calculator, which uses current UK lending criteria and stress testing requirements.
Should I choose a fixed or variable rate mortgage?
Fixed-rate mortgages offer payment certainty for 2-5 years (or longer), protecting you from interest rate rises. Variable rates (including tracker and discount mortgages) may be lower initially but can increase if the Bank of England raises base rates. Fixed rates are popular when rates are expected to rise, while variable rates may suit those expecting rates to fall or planning to remortgage soon. Compare both options and see the long-term cost difference using our Mortgage Comparison Calculator.
