How interest-only loans work:
During the interest-only period, you only pay the interest charges. Your loan balance stays the same. After this period ends, your repayments increase significantly because you must pay both principal and interest over the remaining term.
Important: Interest-only loans typically cost more overall than principal and interest loans because you pay interest on the full loan amount for longer.
