Comparing Axos Bank vs. SoFi Bank

Updated: Invalid Date

Executive Summary

Axos ONE and SoFi Savings are both primarily meant for those ready to move their "financial lives" (checking, direct deposits) to a new institution and meeting requirements in the checking accounts.

The Real Difference:

SoFi Saving's current 3.80% APY includes a temporary boost that expires after 6 months after which it reverts to 3.10% based on today's data. Axos ONE's 4.21% APY is their standard rate for users who meet requirements. Recent Banksparency data shows Axos consistently tracks slightly above SoFi without the risk of a "rate cliff" half a year later.

The Verdict
  • Choose Axos ONE if you want the highest sustainable rate, expanded FDIC coverage (up to $265M with VIP Banking), and greater ATM access.
  • Choose SoFi if you want the greater product ecosystem and don't mind the 6-month boost expiration. It's likely that SoFi will keep its rates farily competitive.
  • Just want a savings account? If you don't want to switch checking accounts, skip both and go with Axos Summit which offers an APY of 3.75%.

The bottom line: you can't really go wrong with either Axos or SoFi, especially when compared to the near zero interest rates at many brick-and-mortar or big banks. But don't think of them as merely savings accounts separate from your normal banking, but as replacements for your overall banking needs.

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 363-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.
