Book with these numbersUnderstanding your repayments
Your repayment is made up of two parts: interest (the cost of borrowing) and principal (paying down what you owe). Early in the loan most of each repayment goes to interest; over time more goes to principal.
Even a small change in your interest rate can make a big difference over 25–30 years. If your rate looks higher than what's on offer today, it may be worth checking whether refinancing could save you money.
