CD Ladder Builder
Spread a deposit over staggered maturities so cash frees up every year while the long terms keep earning. Adjust the rungs and watch the blended yield shift.

When a ladder beats choosing a single term
Putting everything into the top short-term rate secures the best headline number but leaves the whole balance exposed to next year's market. Putting everything into the longest term buys certainty but strands the money. A ladder blends the two: a middle yield, plus a penalty-free decision point every year.
How that trade reads depends on the money's job. An emergency-adjacent reserve wants the ladder. Money with a fixed date — tuition due in a known month — wants a single CD maturing just before it, and no ladder at all.
The two ways a ladder goes wrong
The first failure is overbuilding: pile too many rungs onto a small balance and you create certificates whose maturities demand more attention than their yield returns. Below roughly $2,500 a rung, use fewer rungs or a single CD.
The second is forgetting that every rung auto-renews like any other CD. Five rungs means five maturity notices, five grace periods, and five chances for a bank's default renewal to swallow the rate you planned on. Set the calendar reminders when you open the ladder, not when the first notice arrives.
