How Much Should I Keep in a HYSA?

TL;DR: Direct Answer

3-6 months of essential expenses if you're working dual-income, 6-12 months if single-income, 9-12 months if self-employed, and 12-24 months of expenses if retired (the cash bucket). Anything above your target is over-allocated to cash and is bleeding purchasing power to inflation. The excess should move to CDs, T-bills, or MYGAs depending on your time horizon.

Rates change often. Get an email when they do. Figures in this article are kept for context, not as today’s rate; confirm with the bank before you decide. For reference (latest checks, September 2026): Leading online savings accounts paid about 3.00% to 4.00% APY (bank sites, September 24, 2026); the best nationally available 5-year CDs paid 4.35% to 4.50% APY (DepositAccounts, September 24, 2026); and A-rated 5-year MYGAs topped out around 5.50% to 6.05% (public carrier rate sheets, October 14, 2026). The Fed's target range is 3.75% to 4.00% (raised September 16, 2026, +0.25 point).Email me when rates change →

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.

Quick answer

The right HYSA balance depends on your income stability, not your net worth. Working households: 3-12 months of essential expenses depending on income reliability. Retirees: 12-24 months as a cash bucket against sequence-of-returns risk. Business owners or self-employed: 9-12 months plus business reserves.

Anything held in HYSA above the appropriate target is over-allocated cash. Over-allocated cash bleeds 2-4% per year to inflation drag (real yield = nominal yield minus CPI). It's safe, but it's not earning what it should.

Why this matters

The two failure modes are symmetric:

The math says: hold the minimum cash that lets you sleep through any reasonable surprise, and put everything else to higher-yielding work.

Worked example with $ numbers

A 62-year-old married couple, both retired, with $35,000/month in essential expenses. Pension + SS = $14,000/month, leaving $21,000/month to fund from portfolio. Target cash bucket: 18 months of the portfolio draw = $378,000 in HYSA.

Their actual cash: $620,000. Surplus: $242,000.

Allocation of the surplus to fixed-rate vehicles:

By moving the surplus, the couple keeps the same liquidity buffer but adds ~$12,800/year of guaranteed credited interest, locked for 3-5 years. If HYSA rates drop to 3.50% during that period, the protected income is roughly $4,500/year above what they'd have earned leaving everything in HYSA.

What to do next

Follow-up Questions

Is there such a thing as too much cash in a HYSA?
Yes. Cash beyond your appropriate buffer bleeds 2-4% per year to inflation drag. After 10 years that's a meaningful loss of purchasing power.
Does the HYSA target include retirement accounts?
No. HYSA target is taxable, immediately-accessible cash. Retirement accounts (401k, IRA) are separate and serve a different purpose.
Should I count brokerage cash sweep toward my HYSA target?
Yes if the yield is comparable and access is fast. Brokerage sweep at 4%+ FDIC-pass-through is functionally equivalent to a HYSA.
How much cash should a retiree drawing $80K/year keep liquid?
Typically $80K-$160K (12-24 months) in HYSA, with another $80K-$160K in a 1-3 year CD or T-bill ladder as the second tier. The remainder works harder.
What about a HELOC instead of more cash?
HELOC is a backup, not a substitute. Banks can freeze HELOCs. They did mass freezes in 2008. Real cash for real emergencies.
Does the answer change in a recession?
Marginally. If your job is at higher risk, bump the buffer 50%. If you're retired, your cash bucket is already sized for downturns. Don't double up.
Should business owners keep separate HYSAs for personal and business?
Yes. Separate ownership categories (better FDIC structure) and cleaner bookkeeping. Don't comingle.
