Interest Rates & APY

Capital One

6.5 / 10.0

While the 360 Checking account does pay interest, the APY is modest compared to specialized high-yield checking accounts or its own high-yield savings counterpart. However, it still outperforms the near-zero rates typically offered by traditional national megabanks.

Sainsburys Bank

9.0 / 10.0

Legacy terms maintained standard competitive retail fee structures without burdensome maintenance fees, but product closure makes fee efficiency irrelevant for prospective clients. Ongoing account utility remains strictly constrained.

Sainsburys Bank

6.0 / 10.0
