Understanding the numbers
The monthly payment covers both principal (loan repayment) and interest. Early payments are mostly interest — the amortisation schedule shows exactly how this splits each year. The total interest figure shows the real cost of borrowing over the full term.
On a 25-year UK mortgage at 5%, you'll pay roughly 75% of the loan in interest. Cutting the term to 20 years drops the interest by about 35% — saving tens of thousands of pounds for a higher monthly payment.
