Ally High Yield CD review
Best for: CD beginners who want $0 minimums and a best-rate guarantee.
Ally's 1-year CD pays 4.50% — now the highest 1-year CD rate in this set — with no minimum deposit and a Ten Day Best Rate Guarantee — if the rate rises within 10 days of opening, you automatically get the higher rate.
CD terms: 12-month term at 4.50% APY. No minimum deposit. Ten Day Best Rate Guarantee: if Ally's rate rises within 10 days of opening, you get the higher rate.
Rate note: 12-month term. Also 4.25% on 3-year and 4.50% on 5-year terms (Ally rates page, APYs accurate as of 10/30/2026).
Standout features
- $0 minimum — rare for a top-tier CD rate.
- Ten Day Best Rate Guarantee protects you if rates rise right after you lock in.
- No monthly fees; 10-day grace period at maturity.
Honest drawbacks
- No specialty CDs (no no-penalty or bump-up options).
- 60 days' interest penalty if you withdraw early.
