Savings account vs MYGA, after tax
What $100,000 earns in 5 years: savings account vs MYGA, after tax
Rates used: Savings account 4.00%, the top online savings rate we tracked (bank sites, September 24, 2026); savings rates can change any day; 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).
| Savings account, interest taxed every year | $116,604 |
|---|---|
| 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 savings account, after tax | $9,531 |
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.

The six mainstream no-minimum HYSAs
| Bank | APY | Notable | Best for |
|---|---|---|---|
| Marcus | 3.50% | Goldman Sachs Bank backing | Minimalist savers who want zero friction |
| Synchrony | 3.30% | ATM card included (rare) | Yield-focused savers who want ATM access |
| Barclays | 3.20% | UK megabank parent | Yield-focused savers who like global parent |
| American Express | 3.10% | Amex card integration | Existing Amex cardholders |
| Capital One 360 Performance Savings | 3.10% | Took over Discover's online savings (Discover's savings page redirects here) | Savers who want branches/cafés plus online access |
| Ally | 3.00% | Savings Buckets + checking ecosystem | Savers who want a full online banking stack |
Why open with $1?
Three legitimate reasons to use no-minimum HYSAs even if you have a large balance:
- Test the bank's UX before funding heavily. Open, transfer $100, try a withdrawal, test customer service. Then move serious money once you're comfortable.
- Maintain optionality. If you draw the account down to fund a purchase, no-minimum means the account stays open earning the same rate when you re-fund.
- Parallel accounts for separation. Marcus for emergency fund, Ally for sinking funds, Capital One 360 for tax escrow. Each is opened with whatever amount and earns the same APY on every dollar.

When 'no minimum' becomes 'wrong tool'
The marketing pitch for no-minimum HYSAs is universal accessibility, which is exactly right for emergency funds and small savers. But once your liquid cash is comfortably set aside (3-12 months of expenses), the marginal dollar in a HYSA is doing worse than it could.
The math at $50K, $100K, $250K (5-year horizon)
Assumes 32% federal + 9.3% CA bracket (combined 41.3% on ordinary interest). HYSA at 4.25% (held flat, generous given Fed cycle history). 5-yr MYGA at 5.65% guaranteed, A-rated carrier (both June 2026 rates).
| Balance | HYSA 5-yr ending (after tax) | MYGA 5-yr ending (gross) | MYGA advantage |
|---|---|---|---|
| $50,000 | $56,541 | $65,818 | +$9,277 (+16.4%) |
| $100,000 | $113,082 | $131,636 | +$18,554 (+16.4%) |
| $250,000 | $282,706 | $329,090 | +$46,384 (+16.4%) |
The percentage gap is the same (because the math scales linearly), but the dollar gap is meaningful at $100K+. At $250K, that's enough to add 9-12 months of retirement income.
How to deploy a no-minimum HYSA correctly
Step 1: Calculate your "untouchable" cash
What's your real 12-month outflow? Mortgage + bills + insurance + travel + variable expenses. Multiply by 1.0. That's your HYSA target.
Step 2: Keep that in your favorite no-minimum HYSA
Pick from the six above based on your preference (rate, UX, ecosystem). Don't sweat 10 bps differences.
Step 3: Anything above that, ask "do I need this liquid in the next 3 years?"
If no, a 3-yr or 5-yr MYGA contractually locks the rate AND defers tax. If yes, keep it in the HYSA.

My take
For zero-friction emergency-fund and short-term savings, Marcus, Ally, Synchrony, Barclays, Amex, and Capital One 360 are all excellent and effectively interchangeable. Pick by ecosystem fit (Ally if you want checking, Synchrony if you want ATM, Amex if you have an Amex card, Marcus if you want simplest) more than by 10-15 bps of rate. For amounts above your 12-month liquid floor, run the HYSA-vs-MYGA math at your bracket. The MYGA usually wins meaningfully.
