Comparing Capital One vs. SoFi Bank
Executive Summary
SoFi Bank offers a competitive 4.00% APY on its SoFi Savings account, which is available online and includes a temporary 0.70% APY boost for six months, provided customers set up direct deposit or opt for a $10/month subscription. In contrast, Capital One's 360 Performance Savings account provides a solid 3.30% APY with no direct deposit requirement, but it lacks the promotional boost that SoFi offers. Both accounts have no minimum deposit or maintenance fees, making them accessible options. However, for those seeking the highest yield, SoFi Bank's offering is the clear winner.
