Yes — every HYSA at the major online banks is FDIC-insured up to $250,000 per depositor per ownership category, identical protection to a brick-and-mortar bank. Verify the FDIC certificate number on FDIC.gov BankFind before depositing.

What's the difference between APY and APR?

APY (annual percentage yield) includes the effect of compounding; APR does not. For savings accounts, banks must advertise APY by federal Truth in Savings rules — APR is used on the loan side. Comparing APY-to-APY is always apples-to-apples.

How much does a high-yield savings account cost?

By Yinka Olayokun Published April 18, 2026 Updated May 19, 2026

Direct Answer

The leading high-yield savings accounts cost $0 — no monthly fee, no minimum balance, no transaction limits inside the 6-per-month Reg D guideline — and pay 4.00%–4.50% APY in 2026. Keeping $10,000 at a top HYSA earns roughly $420 a year, versus $42 at the FDIC national-average rate of 0.42%. The real "cost" of using a traditional bank is the foregone interest, about $380 a year per $10,000.

Cost scenarios

Scenario	Cost	Notes
Top online HYSA (Ally, Marcus, SoFi)	$0 / year	4.00–4.50% APY, no minimums
Brick-and-mortar national savings	$0 / year (but ~0.42% APY)	~$380/yr foregone interest per $10k vs HYSA
Premium 'relationship' savings tier	$0–$25 / month if balance < min	Fee waived above $25k balance
Excess withdrawal fee (Reg D legacy)	$5–$15 per occurrence	Still charged at many banks despite Reg D suspension

Where the hidden costs live

True "high-yield" savings at online-only banks (Ally, Marcus, SoFi, Capital One 360, Discover) carry zero ongoing cost. Costs creep in at branch-based banks via paper-statement fees, dormant-account fees, or excess-withdrawal fees that survived the 2020 suspension of Regulation D. Read the fee schedule before opening — if any line item shows a dollar amount, look elsewhere.

The opportunity cost is the real price

The FDIC national average savings rate is 0.42%. The top quartile of online HYSAs pay 4.00%+. On a $20,000 emergency fund that gap is about $760 per year, every year. That is the true "cost" of staying with a low-rate account — and it's tax-advantaged only inside an IRA.
