When a high-yield savings account beats a CD

A certificate of deposit locks a rate for a set term. A high-yield savings account lets you move money without a penalty. The CD wins only when you are sure you will not need the cash before the term ends and the extra yield covers that lock-in. Compare the APY after fees, not the headline rate. Some savings accounts drop the rate after a promotional window or once the balance crosses a cap. A 12-month CD with a lower but guaranteed rate can still beat a teaser savings offer that lasts 90 days. Keep three to six months of expenses in the savings account even if a CD pays more. Breaking a CD early usually costs several months of interest, which wipes out the advantage the moment a car repair or a medical bill shows up. If you already have the emergency fund, ladder shorter CDs instead of one long term. A 3-, 6-, and 12-month mix gives you cash back on a schedule while the rest still earns a fixed rate.
