CD vs Money Market Account (2026): Pay for Liquidity, or Lock the Rate?
This is the simplest comparison on the page. Bank money market accounts (MMAs) and CDs are both FDIC-insured deposits at the same institution. The difference is the lock. MMAs let you withdraw on demand (with some institutions still enforcing the old Regulation D 6-per-month limit, even though Fed eliminated the requirement in 2020). CDs lock the rate for a term and charge a penalty (typically 3-12 months of interest) for early withdrawal.
The yield gap between top MMAs and short CDs sits around 30-70 bps in 2026. That's your premium for accepting the lock. The decision is purely about whether you'll need the money during the term.
CD vs MYGA, after tax
What $100,000 earns in 5 years: CD vs MYGA, after tax
Rates used: CD 4.50%, the top nationally available 5-year CD (DepositAccounts, September 24, 2026); change it to the rate you are offered. MYGA 5.95%, the best A-rated rate we track as of October 13, 2026: Delaware Life Pinnacle Plus 5-year (AM Best A-, negative outlook, 7/31/2026), $100,000 and up, effective October 6, 2026 (Delaware Life rate sheet).
| CD, interest taxed every year | $118,826 |
|---|---|
| MYGA, tax-deferred, before tax | $133,507 |
| MYGA after paying tax on all the interest at withdrawal | $126,136 |
| Tax deferral alone adds about | $674 |
| MYGA ahead of the CD, after tax | $7,310 |
Assumes 22% federal and 0% state income tax, no withdrawals, rates held for the whole term. MYGA interest is taxed as ordinary income when you withdraw it, not as capital gains. Gains taken before age 59 1/2 can owe a 10% IRS penalty, and cashing out early can cost a surrender charge. In an IRA both grow tax-deferred, so the edge there is the rate alone. Bank and credit union deposits are FDIC or NCUA insured up to the limits; a MYGA is backed by the issuing insurer's claims-paying ability and your state's guaranty association up to its limits, not the FDIC.

When CDs win
- You won't touch the money for the term. The 30-70 bps yield pickup compounds. Over $250K at 0.60% spread for 12 months: $1,500.
- You want rate certainty. CDs lock the rate. MMAs can be cut 50-200 bps if the Fed cuts.
- You're laddering. 1, 2, 3, 4, 5-year ladder gives reinvestment optionality without locking everything long.
- Bank promo rate is unusually high. 5.10-5.25% promo CDs occasionally beat any MMA by 100+ bps. Take it.
- You don't want temptation. Some savers do better with money they can't easily access.
When Bank Money Market Account (MMA) wins
- You might need the money in the next 12 months. Even a small penalty wipes out the CD's yield advantage.
- It's your emergency fund. Liquidity is the entire purpose.
- You're parking incoming cash awaiting deployment (closing, tax bill, investment). CDs introduce friction; MMAs don't.
- Rates are expected to rise. MMAs reprice up with the Fed. CDs are stuck at the rate you locked.
- You want check-writing or debit-card access on the balance. CDs don't offer it. Many MMAs do.
Worked example: $250,000 over the planning horizon
You have $100,000 and you're not sure whether you'll need it in 6-12 months for a possible business opportunity. Two scenarios:
Option A: 12-month CD at 4.80%.
If held to maturity: $4,800 gross interest. After 24% federal + 5% state: $3,408 net. If you have to break it at month 6, penalty = 3 months interest = $1,200, leaving you with $2,400 gross / ~$1,700 net.
Option B: MMA at 4.30%.
If held 12 months: $4,300 gross. After tax: $3,053. If used at month 6: $2,150 gross / $1,527 net. No penalty, but the rate could drop during the period.
If you definitely don't break the CD: CD wins by $355/year. If there's a 30% probability you break it: expected value of CD = 0.7 x $3,408 + 0.3 x $1,700 = $2,895. Expected MMA = $3,053. MMA wins by $158 in expectation. Lesson: lock only if you're highly confident you won't need access.
Tax implications
Both are taxed identically: ordinary income, federal and state, on Form 1099-INT. No tax advantage to either.
If you're shopping for after-tax efficiency, neither beats Treasury bills (state-tax-exempt) or muni money market funds (federal-tax-exempt). For high earners in high-tax states, consider those alternatives over a bank MMA.
