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.

Both rates float.

A higher Fed target does not force either bank to raise its savings rate; each sets its own.

Marcus Online Savings vs. a 5-year MYGA
Savings is the right home for emergency money. For money you will not touch for three to five years, a multi-year guaranteed annuity fixes a higher rate and defers the tax.
| $250,000 for 5 years | Marcus Online Savings (if 3.50% held) | 5-yr MYGA at 5.50% |
|---|---|---|
| Rate | 3.50% APY, variable | 5.50%, fixed for the term |
| Tax on interest | Every year (1099-INT) | Deferred until withdrawn |
| Value after 5 years, after 24% federal tax | ~$283,100 | ~$308,300 (tax paid at the end) |
| Protection | FDIC, $250,000 per depositor, per ownership category | Insurer claims-paying ability + state guaranty association (limits vary by state) |
| Getting money out | Any time | Surrender charge above the free-withdrawal amount; IRS 10% penalty before 59½ |
About $23,200 more after tax on the MYGA if the savings rate held all five years (24% federal bracket, state tax ignored). Savings rates are not fixed, so the real gap depends on where they go. Fixed annuity benchmark: carriers rated A or better topped out around 5.50% to 6.05% on 5-year compound-interest MYGAs, per public carrier rate sheets, October 14, 2026. Rates vary by state, premium and carrier.
