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. General education, not tax, legal or financial advice.

Do not let the app pick for you
Higher rates were available the same week: Live Oak Bank 4.00% (as of September 8, 2026) and Sallie Mae 3.85% (September 24, 2026). On $50,000, each 0.25 point is about $125 a year.
Marcus 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 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| Tax on interest | Every year (1099-INT) | Deferred until withdrawn |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.

Mobile-app savings accounts: FAQ
Which high-yield savings account has the best mobile app?
It depends on the feature you want. Ally's app has Buckets (named sub-goals inside one savings account); SoFi's has Vaults and puts checking and savings together; Capital One's app had a 4.8/5 App Store and 4.5/5 Google Play rating as of July 27, 2026, per Capital One.
What do these accounts pay?
As of September 24, 2026: Marcus 3.50% APY, SoFi 3.30% with eligible direct deposit (as of September 23), Capital One 360 Performance Savings 3.10%, Ally 3.00%. Rates are variable.
Is an app-first bank FDIC insured?
The ones here are banks themselves: Goldman Sachs Bank USA (cert 33124), SoFi Bank, N.A. (26881), Capital One, N.A. (4297), Ally Bank (57803). Coverage is $250,000 per depositor, per bank, per ownership category.
Should I pick a savings account for its app?
Rate and terms first, app second. The rate gap between these four was 0.50 point on September 24, 2026, about $250 a year on $50,000.
My take
Pick on rate and terms, then use app features as the tiebreaker: Buckets or Vaults if you save toward several goals, Marcus if you want the highest rate of this group.

Disclosure
HYSA rates change daily and vary by bank, account tier, and promotional period. The rates shown reflect publicly posted APYs as of the date stated above and may be different by the time you open an account. Always confirm the current APY on the bank's own site before transferring funds. FDIC coverage is $250,000 per depositor, per insured bank, per ownership category; NCUA coverage at federally insured credit unions is the same limit. This article is general information for educational purposes; it is not a personalized recommendation, solicitation, or offer of any specific bank account, brokerage product, annuity, or other financial product. Hans Goldstein is an independent licensed insurance producer (NPN 20602398) appointed with multiple A-rated annuity carriers; he is not a bank employee, broker-dealer registered representative, or fiduciary investment advisor. No compensation has been received from any bank or credit union in connection with this review. Multi-year guaranteed annuities (MYGAs) referenced here are long-term insurance contracts with surrender charges and are not suitable for funds you may need before the end of the surrender period; they are not FDIC insured and are backed instead by the issuing carrier and the state guaranty association of the owner's state of residence (typically $250,000-$300,000 of present value). Always read the actual account disclosure or contract and consult a licensed advisor before committing funds.
