Choose CD when

  • You're building a CD ladder for periodic access
  • Your HYSA rate is below the best available CD rate

Frequently asked questions

Is a CD better than a HYSA right now?

CDs offer higher guaranteed rates but lock your money in for the full term. HYSAs offer flexibility but rates can change. The right choice depends primarily on whether you need access to your funds during the term.

Can HYSA rates change?

Yes — HYSA rates are variable and follow the Federal funds rate. When the Fed cuts rates, HYSA rates typically drop within weeks. CDs lock in today's rate for the full term, protecting against rate cuts.

What happens if I withdraw from a CD early?

Most CDs charge an early withdrawal penalty, typically 3 months of interest for terms under one year and 6 months of interest for one-year terms and longer. No-penalty CDs exist but offer slightly lower rates.

Methodology: Interest calculated using monthly compound interest formula — principal × ((1 + APY/12)^months − 1). Monthly HYSA contributions compound each month. Rate-drop scenarios simulate the HYSA rate falling by the selected amount at the midpoint of the CD term. Early withdrawal penalty estimate assumes 3 months of interest for terms under 1 year and 6 months for 1-year terms and above.

Rates shown are illustrative examples as of 2026. Actual rates vary by institution and change without notice. Verify current rates directly with your bank or credit union before depositing. Interest income from both HYSAs and CDs is taxable as ordinary income in the year earned.
