The Bottom Line

Who pays more interest on $10,000? Openbank pays $35 more than SoFi Bank annually ($400 vs $365).

The Openbank and SoFi Bank savings accounts are very similar. Choose Openbank if getting the best rate matters most, you want a no-strings-attached account, or you want to avoid a promo rate with a scheduled drop. Choose SoFi Bank if mobile app quality matters, or you want Zelle for quick transfers.

Important Considerations

The key difference? SoFi Bank's 4.00% rate includes a promotional bonus for the first 6 months, after which it reverts to the standard rate (currently 3.30%). Openbank's 4.00% rate has no scheduled drop, though all rates are subject to change.

SoFi Bank requires a checking account to unlock its top savings rate, while Openbank offers its savings account standalone.

How to read these metrics(Click to expand)

Trends & Velocity

  • Trend: The general direction of the rate over the analyzed period. Useful for spotting if a bank is currently aggressive or pulling back.
  • Velocity (bps/mo): Speed of change. A high positive number means they raise rates quickly. 10 bps = 0.10%.
  • Adjustments/Mo: "Twitchiness." High frequency means the rate changes constantly; low frequency means it's stable.

Risk & Range

  • High/Low: The absolute ceiling and floor of the rate during the 365-day window.
  • Volatility Score: Lower is better for predictability. It indicates how wildly the rate swings relative to its average.
  • Days Since Change: If this number is high (e.g., >90), the rate is very sticky. If low, it changed recently.
