The Federal Deposit Insurance Corporation (FDIC) protects depositors against loss if an FDIC-member bank fails, within defined limits. Coverage applies to checking, savings, money market deposit accounts, and certificates of deposit - not to stocks, bonds, mutual funds, or crypto held at the same institution. The standard insurance amount is $250,000 per depositor, per insured bank, for each ownership category. Knowing how categories split lets you keep large cash balances protected without assuming every dollar everywhere is covered.
What FDIC insurance guarantees
If a covered bank closes, FDIC (or the acquiring institution) typically pays insured deposits up to the limit or moves accounts to a healthy bank. Customers continue accessing insured funds with minimal disruption in most resolutions. Uninsured amounts above limits may be recovered partially through dividends from the failed bank's liquidation, but that process is uncertain and slow.
CDs at FDIC banks carry the same insurance as savings when registered properly. Model CD maturity values with the CD Calculator; insurance covers principal and accrued interest up to applicable limits at failure.
The $250,000 per depositor rule of thumb
The widely cited $250,000 limit applies separately in each ownership category at each FDIC-insured bank. Single accounts (one owner, no beneficiaries) share one category bucket. Certain retirement accounts, trust accounts, and corporation accounts have their own categories with separate limits. The limit includes principal plus accrued interest on the date of failure.
Joint account coverage
Joint accounts owned by two people are insured up to $250,000 per co-owner in the joint category, assuming both signatories are eligible depositors and ownership is truly joint. Two eligible co-owners could insure up to $500,000 in joint accounts at one bank, plus each owner's single accounts up to $250,000 each, when structured correctly. Mislabeled pay-on-death or informal arrangements do not create extra coverage.
Payable-on-death (POD) accounts
POD beneficiaries can increase coverage in the revocable trust account category when documentation meets FDIC requirements. Title on the account must match bank records. Verify with the institution's deposit insurance specialist for large balances.
CDs and accrued interest
A $240,000 CD that accrues $12,000 interest before failure has $252,000 in that category; $2,000 may be uninsured unless other categories absorb it. Laddering CDs does not by itself increase insurance if all are single-owner accounts at the same bank totaling above $250,000. Splitting across banks or using joint and retirement categories does.

What FDIC does not cover
- Investment products: mutual funds, annuities, stocks, bonds.
- Safe deposit box contents.
- Losses from fraud or theft (separate bank policies may apply).
- Deposits at non-member institutions unless another insurer applies.
Credit unions use NCUSIF insurance with parallel but not identical rules. Confirm membership and category limits separately.
Worked example: household with two banks
Alex (single) holds $180,000 in savings and $70,000 in a twelve-month CD at Bank One, same ownership category. Total $250,000 is fully insured. A $5,000 interest accrual before failure would push $5,000 uninsured unless Alex moves excess before failure or opens a joint POD structure meeting FDIC rules.
At Bank Two, Alex holds $200,000 in a joint account with a spouse. Joint category insures up to $500,000 for two owners ($250,000 each co-owner's share). The $200,000 balance is fully covered. Combined across banks, coverage follows per-bank, per-category math - not a single national cap.
Practical steps for large cash holders
Use the FDIC's Electronic Deposit Insurance Estimator (EDIE) on fdic.gov for account-specific answers. Keep account titles accurate after marriage or divorce. Spread balances above limits across member banks or categories intentionally rather than accidentally duplicating risk at one brand. Brokered CDs still require the issuing bank's membership and proper registration.
Bank mergers and name changes
When banks merge, FDIC typically covers accounts under both charters during a transition window, then combines balances under one charter for limit purposes. Letters from the acquiring bank explain timing. After a merger closes, recalculate totals so combined single accounts do not silently exceed $250,000 in one category. Online brand names that share a charter still aggregate together even when marketing sites look separate.
Credit unions and NCUSIF
Member share accounts at federally insured credit unions fall under NCUSIF, a separate system from FDIC with its own limits and category rules. Do not assume FDIC language in a blog post applies verbatim to your credit union statement. Ask the institution for its insurance disclosure when balances grow large.
Business accounts use different ownership categories than personal single accounts. Mixing business revenue deposits with personal emergency cash at one bank can complicate insurance calculations after failure.
Beneficiaries on POD accounts should know which institution holds deposits so they can file claims quickly if the owner dies. FDIC processes depend on accurate legal titles matching bank records.
International accounts at U.S. branches of foreign banks follow different rules. Confirm FDIC membership on the specific U.S. entity accepting your deposit, not only the parent brand name.
Trust officers at larger banks can walk through EDIE inputs with you before you move proceeds from a home sale or inheritance into multiple accounts.
