High-yield savings vs CDs: rates, access and penalties
A high APY is only part of the comparison. Before choosing a US savings account or certificate of deposit (CD), check when you can take your money out—and what leaving early costs.

The short version
Start with your spending date. Compare access and term first, then the eligible APY. A no-penalty CD still has withdrawal conditions.
- 01
Savings
Variable APY. Check the transfer route.
- 02
Standard CD
Fixed term. Price the early exit.
- 03
No-penalty CD
Check the waiting period and full-balance rule.
Savings, a standard CD and a no-penalty CD

| Account | Rate type | Access and conditions |
|---|---|---|
 Capital One360 Performance Savings | Rate typeVariable APY | No monthly fee or minimum balance. Withdraw online or at a branch; ATM access requires a transfer to checking first. [1] |
 MarcusHigh-Yield CD | Rate typeFixed rate | USD 500 minimum balance; terms from 6 months to 6 years. Withdrawing the balance before maturity incurs an early withdrawal penalty. [2] |
 AllyNo Penalty CD | Rate typeFixed APY | 11-month term, no minimum opening deposit or monthly maintenance fee. Withdraw the full balance and interest without penalty after the first 6 days following funding. [3] |
1. Match the term to when you need the money
Savings can accommodate changing plans, but transfer timing still matters. Capital One’s APY can change after opening. The Marcus High-Yield CD fixes its rate once its minimum funding requirement is met; Ally’s No Penalty CD fixes APY for its term. APY includes compounding—compare current offers on the same day.
2. Read the no-penalty withdrawal conditions
For Ally’s 11-month No Penalty CD, penalty-free withdrawal means the full balance plus interest, after the first six days following funding. That differs from transferring a chosen amount out of savings. Confirm the funding date and transfer timing before relying on the money for a payment.

3. Calculate the cost of leaving a CD early
Marcus bases its High-Yield CD penalty on the original principal: 90 days of interest for terms up to and including one year, 180 days for terms over one through five years, and 270 days for terms over five years. The example below shows how crossing the one-year term boundary changes the cost.

Illustrative example · USD
Assume full withdrawal before maturity, USD 10,000 original principal and a hypothetical 4.00% annual interest rate. These bars show penalties, not earnings.
- 12-month CD · 90 days
- USD 98.63
- USD 10,000 × 0.04 ÷ 365 × 90
- 18-month CD · 180 days
- USD 197.26
- USD 10,000 × 0.04 ÷ 365 × 180
18-month early-exit penalty: +USD 98.63
Illustrative 4.00% interest rate, not APY or a current Marcus quote. Assumes a 365-day year and rounds to cents; Marcus uses 366 days in a leap year. This compares penalties only, before any tax effects.
Before you move your money
- Record the exact account, eligible APY and funding date.

Explore US CDsCommon questions
Is a CD always better than high-yield savings?
Compare the current APY, term and access rules. A fixed CD rate can suit a known time horizon, but an early withdrawal penalty changes the outcome.
Can I withdraw an Ally No Penalty CD immediately?
Penalty-free full-balance withdrawal is available after the first six days following funding. It is not immediate access on the funding date.
Does a 12-month Marcus CD use a 180-day penalty?
No. Its disclosed boundary includes one year in the 90-day band. The 180-day band applies to terms over one year through five years.
