Our Expert Opinion on Marcus Online Savings Account

Jonny PeaseCo-Founder, DepositScout

Marcus's Online Savings Account pays 3.75% right now, but that includes a 0.49% boost for 12 months, after which the rate drops to 3.24%, so the headline figure flatters it a little. It sits below the easy access market average and 1.25% behind the category leader at 5.00%, which is a meaningful gap. The rate does beat August 2026 CPI of 3.1% by 0.65%, so your money keeps pace with inflation for now. If you want to stay easy access, First Active's Instant Access Savings Account offers 4.05%.
