The Bottom Line

Who pays more interest on $10,000? SoFi Bank pays $50 more than BMO Alto annually ($365 vs $315).

Choose BMO Alto if you want a no-strings-attached account, or you want to avoid a promo rate with a scheduled drop. Choose SoFi Bank if getting the best rate matters most, you're an iPhone user (no iOS app for BMO Alto), you're an Android user (no Android app for BMO Alto), 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%). BMO Alto's 3.15% 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 BMO Alto 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.
