APY vs. rate, terms, minimums, early-withdrawal penalties, insurance — the complete 6-point checklist for comparing CDs, and the traps that make a "high" rate a bad deal.
Two CDs advertising "great rates" can differ by hundreds of dollars on the same deposit. Comparing them properly takes six checks and about five minutes. Here's the checklist we use to rank every CD in Kansas City.
1. Compare APY, never the "rate"
The interest rate ignores compounding; APY includes it. A 5.00% rate compounded daily is a 5.13% APY — so a bank quoting "5.05% APY" actually beats one quoting a "5.00% rate." Always line up APY against APY. (Full explanation →)
2. Match the term to your real timeline
The highest APY on the board is irrelevant if it's a 5-year term and you need the money in 18 months. Decide your date first, then compare only CDs at or under that horizon. In KC, odd terms (7, 9, 13 months) are often promotional specials that out-pay the standard terms around them — our comparison tables list them all.
3. Check the early-withdrawal penalty
This is where "high-rate" CDs go bad. Penalties typically run 3 months of interest on short CDs to 12+ months on long ones — break a 5-year CD in year one and the penalty can eat every dollar earned. Two CDs with identical APYs are not identical if one charges double the penalty. The fine print is one line; read it.
4. Mind the minimum deposit
KC minimums range from $0 to $10,000+. A spectacular APY with a $10,000 floor is useless for a $3,000 deposit — and "jumbo" CDs ($100k+) sometimes pay *less* than a smaller institution's standard CD. Never assume bigger deposit = better rate; check the minimum column in any KCBanks table.
5. Confirm the insurance
Only compare CDs from FDIC-insured banks or NCUA-insured credit unions — every institution on KCBanks is one or the other, with the certificate number on its profile. Keep any single institution under $250,000. (How deposit insurance works →)
6. Know what happens at maturity
Most CDs auto-renew at whatever rate the bank offers that day — often far below the promotional rate that attracted you. Calendar the maturity date; you typically get a 7–10 day grace window to move the money. The renewal rate is where lazy money goes to die.
Put a dollar figure on the difference
Percentage points feel abstract; dollars don't. On a $25,000 deposit for one year, the gap between a 1.25% CD and a 4.00% CD is about $690. Run your own numbers in the CD calculator, then find who actually pays the most: every KC CD, ranked by APY → — never by advertising (our methodology).
