Mortgage Calculator FAQ's
Our mortgage calculator provides a solid estimate based on standard repayment formulas using the loan amount, interest rate and mortgage term you enter. It’s a great way to understand what your monthly repayments might look like and how different rates or terms affect affordability. However, lenders each use their own affordability models that also consider your income, spending habits, credit history and the type of property you’re buying. That means the exact amount a lender offers may differ from the calculator’s estimate. Once you’ve explored your figures, our advisers can give you a personalised affordability check based on your real circumstances.
No, using the calculator has no impact on your credit score. The tool is completely anonymous and does not run any credit checks or leave any footprints on your credit file. You can use it as many times as you like without affecting future mortgage applications. A credit check is only carried out when you move forward with an Agreement in Principle or full mortgage application.
Not exactly. The calculator gives you a strong indication of your potential monthly payments and what might be affordable, but lenders look at more than simple repayment calculations. They also assess: • Your income type and stability • Existing debt and financial commitments • Your spending patterns • Your credit history • The type and condition of the property Because each lender has different criteria, the exact amount offered may differ from your calculator estimate. Our advisers can compare multiple lenders to give you a more precise figure.
To get the most accurate estimate, you’ll need: • Your deposit amount • Your estimated loan amount • The current or expected interest rate • Your preferred mortgage term (e.g., 25, 30 or 35 years)You don’t need any personal documents for the calculator — just the figures above. It only takes a few seconds to see your estimated monthly repayments.
After reviewing your estimated monthly repayments, the next step is to speak to a mortgage adviser for tailored advice.

Some kind words from our clients
Rachel has been incredible in securing us a mortgage and I cannot recommend her highly enough. The whole process was clear from beginning to end and Rachel kept us up to date every step of the way. We had a tricky property to mortgage and Rachel was able to secure us a good product from a high street lender. I have recommended her to friends and family and would use her again for any future mortgages. Thanks Rachel!
A 5 star experience of first time buying thanks to Rachel and Joanne. I was worried buying a home would come with so much stress but I can honestly say it’s been more or less stress free! Quick and professional communication and even got a better mortgage deal than I thought! Can’t recommend or thank them enough!
Rachel and Jo at Mortgage Force were outstanding start to finish. They went above and beyond with everything they did, helping us to purchase our first home. We've been told many times how stressful buying a house is but with Mortgage Force it felt like a breeze! Rachel was informative and broke everything down so that we fully understood all of the house buying lingo and both Jo and Rachel were friendly, helpful, super quick to respond to any queries and just a pleasure to deal with.
