APY: 0.55% [With $100 minimum balance]

BONUS: $100 [Requirements to qualify]

Alliant's Ultimate Opportunity Savings Account earns an above-average rate and doesn’t charge a monthly fee if you select e-statements.

Alliant Credit Union High-Rate Checking

4.5 NerdWallet rating


APY: 0.25% [With $0 minimum balance]

Alliant offers teen and high-rate checking accounts, neither of which charges a monthly fee.

Alliant Credit Union CD

4.5 NerdWallet rating

1-YEAR APY: 0.55%

3-YEAR APY: 0.60%

5-YEAR APY: 0.65%


Alliant's share certificates come with above-average rates, but opening one does require some cash: You’ll need a $1,000 minimum opening deposit. APYs range from 0.55% to 0.65%; longer terms and larger balances earn higher yields. Compare Alliant's share certificates to other financial institutions' with our CD comparison tool.

Banking Experience

4.5 NerdWallet rating

Alliant's rates are commendable, but its inclusion is really impressive. Other credit unions restrict membership to people who work for certain companies or live in specific communities. With Alliant, you can apply for membership after making a one-time $5 donation to a nonprofit that supports foster children. Alliant will even pay the donation on your behalf.

Of course, Alliant has some flaws. Unlike nearly 2,000 credit unions, it doesn't participate in shared branching, and is completely online. But it does offer a solid online banking platform and a highly rated mobile app, and customer support is available via Twitter and 24/7 by phone.

Members have access to online bill pay and can check their credit scores for free.

Overdraft fees

5.0 NerdWallet rating

Alliant announced in August 2021 that it is eliminating overdraft fees. The credit union is currently refunding fees for overdraft transfers and nonsufficient funds but will eventually stop charging these fees. Other banks and credit unions charge an overdraft fee of around $35, up to several times per day.
