SoFi pays a higher APY today, but APY at every online bank moves monthly. The right pick depends on whether you need ATM access, checking integration, or are using this purely as a parking lot for cash.

Pick SoFi if you want:
SoFi is the better choice when you want full-service online banking with integrated checking.
| Scenario | Ally (4.20% APY) | SoFi (4.60% APY) |
|---|---|---|
| Starting balance | $50,000 | $50,000 |
| 1-year interest (simple) | $2,100 | $2,300 |
| Ending balance | $52,100 | $52,300 |
| Difference | $200/yr — favor of SoFi | |
$200/year is real money — but read the caveat: both rates float. The bank paying more this month may pay less in 6 months. Online HYSAs typically stay within 20-40 bps of each other over time; the leader rotates.
In 2021, the top online HYSAs paid 0.40-0.55% APY. By late 2023 they were paying 4.50-5.30%. As the Fed cut rates from 5.50% to 4.50% in 2024-2025, top HYSAs fell 50-75 bps. Whatever Ally or SoFi pays today is not what you'll earn three years from now.
If you want a rate locked, that's not what these accounts do. Read the MYGA section below.
Both HYSAs above are variable rate. They were paying 0.50% in 2021. They might be paying 2.00% in 2027. You don't lock the rate — you take whatever the bank chooses to credit each month.
If you have cash you genuinely don't need for 3+ years (emergency fund excluded), the closest fixed-rate equivalent is a multi-year guaranteed annuity (MYGA):
Trade-offs vs. an HYSA:
MYGAs don't replace your emergency fund. They replace the excess cash sitting in an HYSA that you know you won't touch for 3-10 years.

For pure HYSA use (emergency fund + short-term cash), the bank with the higher APY today wins on dollars and the bank with better ATM access wins on convenience. Ally pays 4.20% and SoFi pays 4.60%. If the retiree has $200K+ sitting in cash they won't touch for 3-5 years, neither HYSA is the right product — a MYGA at 5.50-5.75% locked is. HYSAs are right for cash you might need in 0-24 months.
Yes. Ally is FDIC-insured under cert #57803. SoFi is FDIC-insured under cert #59458. Both are covered up to $250,000 per depositor, per ownership category, per insured bank. If you hold a joint account, coverage doubles to $500,000 on that account.
Yes. There's no rule limiting you to one HYSA. Many savers split deposits across 2-3 banks for FDIC coverage above $250K, or to chase the highest APY without closing accounts. Ally and SoFi are separate FDIC-insured institutions, so $250K at each = $500K of insured deposits.
Ally ACH transfers settle in 1-3 business days. SoFi ACH transfers settle in 1-3 business days (instant to SoFi accounts). Same-day wires are available at most banks for a fee ($15-30 outbound). Mobile check deposit usually clears next business day with a hold on amounts over $5K.
Ally: 4.7/5 (iOS) / 4.6/5 (Android). SoFi: 4.8/5 (iOS) / 4.5/5 (Android). Both are well-rated. The differences come down to UX preferences (transfer screens, statement export, biometric login). Both support mobile check deposit, external account linking, and goal-based saving features.
Neither bank charges monthly maintenance fees or transaction fees on the standard savings account. Ally: $0 monthly fee. SoFi: $0 monthly fee. Watch for outbound wire fees ($15-30), expedited check delivery fees, and overdraft fees if you link the savings to a checking account that overdrafts (rare on savings).
A multi-year guaranteed annuity (MYGA) at 5.50-5.75% locked for 5 years from an A-rated carrier. HYSAs are variable; MYGAs are fixed. On $100K over 5 years, the difference between a 5.65% locked MYGA and a 4.20% variable HYSA (with realistic rate-cut assumptions) is roughly $7,000-12,000. Trade-off: MYGAs have surrender charges in years 1-5 and only allow ~10% free withdrawals per year. Right for parked cash; wrong for an emergency fund.
Compare your HYSA APY against current MYGA rates — free, independent.
HYSA rates move every month with the Fed. If you want a rate locked for 3, 5, 7, or 10 years on cash you won't touch, a MYGA (multi-year guaranteed annuity) is the closest equivalent. Current top MYGA rates: 5.40-5.75% for 3-5 year terms, fixed. Tax-deferred. State guaranty fund backed.
