Assumptions & how it's worked out

- The rate is assumed constant — in reality it changes when a fixed period ends.
- Doesn't include product fees, insurance, or overpayments.
Questions, answered
- How is the monthly repayment worked out?
- It uses the standard amortisation formula: the loan plus interest spread evenly across every month of the term, so early payments are mostly interest and later ones mostly capital.
- Is this a mortgage offer?
- No. It's an indicative estimate to help you plan. A lender's actual offer depends on affordability checks, your credit file, and the specific product.
