Mortgage Calculator FAQs

How accurate is your mortgage calculator?
Our calculator uses industry-standard mortgage formulas to provide accurate estimates. However, actual mortgage offers may vary based on your credit score, lender criteria, and current market rates. Mortgage rates are typically influenced by the Bank of England base rate and wholesale money market rates such as SONIA (Sterling Overnight Index Average). Always consult with a qualified mortgage adviser for personalised advice.
What deposit do I need for a mortgage?
Most UK lenders require a minimum deposit of 5-10% of the property value, though larger deposits (15-25%) typically secure better interest rates and lower monthly payments. Use our calculator to experiment with different deposit percentages.
Should I choose a repayment or interest-only mortgage?
Repayment mortgages gradually pay off both the loan capital and interest, ensuring you own your home outright at the end of the term. Interest-only mortgages have lower monthly payments but require a separate repayment strategy. Our calculator lets you compare both options.
How can overpayments save me money?
Even small monthly overpayments can significantly reduce your mortgage term and total interest costs. Use our calculator’s overpayment feature to see the potential savings – you might shave years off your mortgage and save thousands in interest.

Mortgage Tips for Cambridgeshire Buyers

  • Check your credit score before applying – better scores secure better rates
  • Compare multiple lenders – rates and terms vary significantly across providers
  • Factor in additional costs – stamp duty, solicitor fees, and surveys add to your purchase
  • Consider fixed vs variable rates – fixed rates provide payment certainty; variable rates may offer initial savings
  • Get a Decision in Principle – strengthens your position when making offers
