Quick Answer

A CD locks your rate for a fixed term but penalizes early withdrawal. A HYSA has a variable rate (can rise or fall) with full liquidity, no penalty. Rates on both move with the Federal Reserve's rate decisions and change weekly — there's no fixed "best" answer, only your specific quoted rates compared.

Both are typically FDIC-insured up to $250,000 per depositor per bank, making the real decision about liquidity and rate certainty, not safety.

Why this tool doesn't show you "today's best rate"

CD and HYSA rates change weekly with Fed policy and bank competition. Any "best rate today" number we hardcoded would be stale within days and could mislead you. Instead, check current rates at FDIC's National Rate data or your own bank/credit union, then plug your real numbers in above.

Sources & Methodology

Methodology: Both accounts compounded monthly at the APY you supply. CD assumes a fixed rate for the full term; HYSA assumes the rate you enter holds for comparison purposes only (its real-world rate is variable and can change at any time). Early withdrawal penalty is modeled as a forfeiture of N months of CD interest, a common but not universal structure — check your specific CD's terms.

Common Questions

Is a CD or a high-yield savings account better?
+
It depends on the rate gap and whether you need liquidity. A CD locks your rate for a fixed term — useful if you expect rates to fall and won't need the cash. A HYSA has a variable rate and full liquidity — useful if you might need the money or expect rates to rise. Compare your specific rates in the calculator above rather than relying on "best rate" lists, which go stale fast.
What happens if I withdraw from a CD early?
+
Most CDs charge an early withdrawal penalty, typically a forfeiture of several months of interest (often 3-6 months for short-term CDs, more for longer terms). This can wipe out the rate advantage entirely. HYSAs have no withdrawal penalty, which is the core liquidity tradeoff.
Are CDs and HYSAs FDIC insured?
+
Yes, both are insured up to $250,000 per depositor, per bank, per ownership category at FDIC-member banks (or NCUA-insured at credit unions). This makes both essentially risk-free for amounts under that threshold.
