The monthly rate is a little lower because interest reaches you sooner. Over a year it adds up to the same.

Our Expert Opinion on First Direct Cash ISA

Jan WatermannCo-Founder, DepositScout

First Direct's Cash ISA pays 2.75%, which is below the market average for Cash ISAs and sits 2.37% behind the category leader at 5.12%, so you are giving up a meaningful amount of interest by staying here out of loyalty. At current CPI of 3.1%, the rate is also 0.35% below inflation, meaning your money loses purchasing power in real terms. The £1 minimum is genuinely flexible and instant access with no penalties is useful, but if returns matter, Moneybox's Open Access Cash ISA at 3.80% or Sidekick's Cash ISA at 3.23% are worth a look.
