Which has the highest APY: SoFi, Marcus, or Ally?

Marcus has the highest no-strings APY at 3.50%. Ally pays 3.10% with no requirements. SoFi pays up to 3.10% Annual Percentage Yield (APY) with eligible direct deposit, and a new account can add a 0.70% Boost on Savings APY to up to 3.80% for up to 6 months (terms apply). If you have eligible direct deposit AND qualify for the Boost, SoFi temporarily wins; otherwise Marcus wins on rate alone.

How does SoFi's promotional APY boost work?

SoFi pays up to 3.10% Annual Percentage Yield (APY) when you set up Eligible Direct Deposit. Open a new SoFi Checking and Savings account with Eligible Direct Deposit by 12/31/26 and a 0.70% APY Boost is added on top, for up to 3.80% APY for up to 6 months. Terms apply. After 6 months the Boost expires and you're back to up to 3.10% with eligible direct deposit. Marcus and Ally don't run promotional boosts — their pitch is steady-state APY without expiration.

Are these banks safe? What about deposit insurance?

All three are FDIC-insured. Marcus and Ally are direct banks — your deposits are insured up to $250K per person, per bank. SoFi uses a sweep network of partner banks, which lets them offer up to $2M in FDIC insurance per account holder by spreading deposits across multiple member banks. All three are safe; SoFi simply has higher coverage limits.

Can I get a checking account with all three?

No. Marcus is savings-only — they don't offer a checking account. SoFi and Ally both offer checking. SoFi pays its APY on savings balances and does not advertise a separate checking rate. Ally pays 0.10% APY on its Spending account with no requirements. If you want one bank for both checking and savings, Marcus is out.

Which has the best mobile app?

Marcus has the highest Apple App Store rating (4.9) but it's a simpler app — savings only, fewer features to break. SoFi's app (4.8) is more feature-rich (banking, investing, loans, credit card all in one). Ally's app (4.7) is solid but the most dated UI. For a clean, focused savings experience, Marcus wins. For an all-in-one financial dashboard, SoFi wins.

What's the SoFi $300 signup bonus?

SoFi's standard tiered bonus is $50 for $1,000–$4,999 in direct deposits within 25 days, or $300 for $5,000+. As of May 2026, SoFi is also running a promotional $400 bonus tier on the same $5,000+ qualifying-deposit requirement (verify the current top tier on the official offer page before signing up). Marcus and Ally don't offer signup bonuses — their pitch is rate, not bonus.

Methodology

We compared each bank on the dimensions that actually shape returns: savings APY (with and without conditions), checking APY, ATM access, signup bonus, FDIC coverage, and the breadth of products available within the same app. We weighted savings APY most heavily for HYSA-shoppers, but flagged the SoFi conditional-rate caveat upfront so direct-deposit-skeptics aren't surprised.

APYs were verified against each bank's published rate disclosures as of April 2026. SoFi is a WalletGrower partner; Marcus and Ally are not. The recommendation logic is the same we'd give a friend.
