Comparing Ally Bank vs. TD Bank

Updated: Mar 24, 2026

Executive Summary

Ally Bank offers a competitive Savings Account with an APY of 3.20%, making it a strong choice for savers, especially given there are no minimum deposit requirements or maintenance fees. This account is online-only and does not require direct deposit, making it accessible and straightforward. In contrast, TD Bank's Signature Savings provides a maximum APY of 2.36%, but this rate is contingent on linking an eligible TD account and maintaining a minimum balance of $250,000. Without meeting these conditions, the APY drops significantly to 0.05%. Therefore, Ally Bank's offering is superior for those seeking higher returns without stringent conditions.

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.
