CD vs High-Yield Savings
Plan when your cash becomes available. Compare safety, access, and estimated interest income before you move money.
Understand the trade-offs, estimate monthly interest, and build a CD ladder so you know exactly when cash lands.
The short version
Two safe cash homes with different trade-offs. Here's how they compare.
- Flexible access to your cash
- Variable interest rate — can change anytime
- Good for emergency funds and short-term reserves
- Often simpler for money you may need soon
- Fixed rate for a set term
- Better for money you don't need right away
- More certainty if held to maturity
- Less flexible before maturity
Note: some brokered CDs may be callable, and selling before maturity may result in a gain or loss.

CD Ladder Builder
Build a ladder of CDs so your money matures in stages instead of all at once. Balance liquidity with fixed-rate earning potential.
How this ladder works
See when each CD matures, when cash becomes available, and how rolling a rung forward keeps the ladder going.
A CD ladder spreads your money across several maturity dates, so part of it becomes available on a schedule instead of all at once.
If you reinvest each maturing rung into a new long-term CD, the ladder keeps renewing over time.
- Shorter spacing gives more frequent access to cash.
- Longer spacing may lock in rates for longer.
- Rolling maturing rungs keeps the ladder going.

Reading your cash events
Some cash events are interest only. Others include your original principal returning at maturity. Reinvested money is not the same as spendable cash — it moves into a new rung instead of your pocket.
A note on payout timing
Not every CD pays cash monthly. Some pay all interest at maturity; others pay periodic interest. This tool uses educational estimates unless you set a specific payout timing per rung.
- • Short ladders prioritize access to your cash.
- • Longer ladders may lock in rates for longer.
- • Mixed ladders balance liquidity and yield.
- • Ladders often work best when emergency cash is already set aside.
Merrill account holders: what to know
Neutral, plain-English notes for anyone considering cash options inside a Merrill account.
- Standard cash sweep rates may be much lower than other savings choices.
- Preferred Deposit may pay more than basic sweep cash but is still a deposit product with its own rate and balance rules.
- Preferred Deposit generally has a $100,000 minimum initial deposit.
- Brokered CDs are commonly available in $1,000 increments.
- Some brokered CDs may be callable.
- Selling a brokered CD before maturity may result in a gain or loss depending on market conditions.
- FDIC insurance limits still matter across deposits at the same institution and ownership category.
