Our Expert Opinion on Marcus 1 Year Fixed Term

Jan WatermannCo-Founder, DepositScout

Marcus's 1 Year Fixed Term pays 4.30%, which sits below the market average for fixed-rate accounts and 1.05% behind the category leader at 5.35%. It does beat inflation by 1.20% against August 2026 CPI of 3.1%, so your money is growing in real terms, but savers who shop around can do better - OakNorth Bank's Fixed Term 12 Months pays 4.96% for the same one-year commitment. The main catch beyond the lock-in is the early closure fee, which wipes out all interest earned if you leave within the first 90 days.
